The effectiveness of sub-Tenon's infiltration of local anaesthesia for cataract surgery

Verghese I, Sivaraj R, Lai YK

Aust N Z J Ophthalmol, 1996 May;24(2):117-20.
PMID: 9199741

PURPOSE: To determine if adequate anesthesia and akinesia could be obtained using an inferonasal quadrant sub-Tenons anaesthesia for cataract surgery.
METHODS: The sub-Tenons method of local anaesthesia was used in 50 patients undergoing extracapsular cataract extraction and lens implantation. The technique following was that described by JD Stevens in his study of 50 patients. Posterior sub-Tenons space was approached through a conjunctival incision in the inferonasal quadrant and the anaesthetic solution delivered by an irrigating cannula. The patients were assessed for residual ocular movements just before surgery. Effectiveness of anaesthesia was assessed during surgery using a verbal pain rating score. Scoring was based on the concept of a visual analogue pain score chart.
RESULTS: Total akinesia was obtained in 20% patients and total anaesthesia in 24% patients. The remainder of the patients had adequate akinesia and anaesthesia to proceed with and complete the surgery.
CONCLUSION: This method provides satisfactory anaesthesia for cataract surgery.

Fulltext Leptomeningeal Carcinomatosis With Optic Nerve Metastasis Secondary to Breast Cancer

Chew C, Wan Hitam WH, Ahmad Tajudin LS

Cureus, 2021 Mar 31;13(3):e14200.
PMID: 33936906 DOI: 10.7759/cureus.14200

Leptomeningeal carcinomatosis (LC) and optic nerve metastasis are uncommon occurrences in breast cancer. We report a rare case of LC with optic nerve infiltration secondary to breast cancer. A 45-year-old lady who was a known case of treated right breast carcinoma six years ago presented with a blurring of vision in both eyes, floaters, and diplopia for one month. She also had recurrent attacks of seizure-like episodes, headache, and vomiting. Examination revealed high blood pressure with tachycardia. Her right eye visual acuity was counting fingers at two feet and 6/36 in the left eye. She had right abducens nerve palsy. Fundoscopy showed bilateral optic disc swelling with pre-retinal, flame-shaped haemorrhages and macular oedema. CT scan of brain and orbit was normal. She was admitted for further investigations. While in the ward, her vision deteriorated further. Her visual acuity in both eyes was at the level of no perception to light. She also developed bilateral abducens nerve palsy and right facial nerve palsy. Subsequently, she started having bilateral hearing loss. There were few episodes of fluctuations in conscious awareness. MRI brain showed mild hydrocephalus. Both optic nerves were thickened and enhanced on T1-weighted and post-gadolinium. Lumbar puncture was performed. There was high opening pressure. Cerebrospinal fluid cytology showed the presence of malignant cells. Family members opted for palliative care in view of poor prognosis. Unfortunately, she succumbed after a month's stay in hospital. Diagnosis of LC and optic nerve infiltration presents a formidable challenge to clinicians especially in the early stages where neuroimaging appears normal and lumbar puncture has high false negatives. Multiple high-volume taps are advised if clinical suspicion of LC is high.

Fulltext Corticosteroid Therapy in Optic Neuropathy Secondary to Nasopharyngeal Carcinoma

Wahab Z, Tai E, Wan Hitam WH, Sonny Teo KS

Cureus, 2021 Mar 06;13(3):e13735.
PMID: 33842113 DOI: 10.7759/cureus.13735

INTRODUCTION: Nasopharyngeal carcinoma (NPC) is a tumor arising from the epithelial cells of the nasopharynx. NPC can spread and invade the base of skull, nasal cavity, paranasal sinuses, pterygopalatine fossa, and apex of the orbit. However, the involvement of the optic nerve in NPC is rare. The purpose of this case report is to report the efficacy of corticosteroid therapy in optic neuropathy secondary to NPC.
CLINICAL CASE: A 56-year-old Chinese woman, an active smoker, presented with a hearing deficit, persistent tinnitus and nasal congestion. Examination and investigations revealed the presence of a mass in the nasopharynx. Tissue biopsy revealed nasopharyngeal carcinoma. However, the Epstein-Barr virus was not tested. She was counseled for chemotherapy, but refused and was subsequently lost to follow up. She presented one year later with right eye ptosis associated with progressive worsening of diplopia and blurring of vision. Examination revealed multiple (second, third, fourth and sixth) cranial nerve involvement. Systemic examination and investigations revealed cervical lymphadenopathy and liver metastasis. Repeated imaging showed that the mass had invaded the base of the skull, cavernous sinus and orbital apices. Pulse dosing of corticosteroid therapy was commenced, resulting in dramatic improvement of vision.
CONCLUSION: Optic neuropathy may be the presenting sign of NPC. Corticosteroid therapy can offer immediate visual improvement.

Fulltext Severe orbital cellulitis secondary to chronic sinusitis: challenges in saving the eye

Diymitra, K. G., Mushawiahti, M., Aida Zairani, M. Z.

Journal of Surgical Academia, 2018;8(1):47-50.
MyJurnal

Orbital cellulitis is a relatively common disease affecting predominantly the paediatric population. Most cases occur as a result of spread from the nearby sinuses. Other causes include penetrating trauma or extension from infected adjacent structures.If left untreated, this condition may result in devastating sequelae such as orbital apex syndrome, cavernous sinus thrombosis, meningitis, cranial nerve palsies, intracranial abscess formation and even death. A 47 year old immunocompetent Burmese lady presented with left eyelid swelling of 2 days duration associated with eye redness, blurring of vision and diplopia. Previously, there was history of right maxillary sinusitis and parapharyngeal abscess 9 months prior to presentation. On examination, she was afebrile with vision of 1/60 for the left eye with positiverelative afferent pupillary defect (RAPD). The eye was proptosed and swollen with restricted extraocular movements in all gazes. Conjunctiva was injected with chemosis and there was corneal epithelial bedewing. Otherwise anterior chamber was quiet and intraocular pressure was 51mmHg. Bilateral fundus examination was normal. Computed tomography (CT) scan of the orbit and paranasal sinus showed dense sinusitis and periosteal abscess at the lateral orbital wall.She was started on intravenous (IV) Cefuroxime and Metronidazole and underwent Functional Endoscopic Sinus Surgery (FESS) and orbital decompression. Intra-operatively there was pus and debris at the left anterior ethmoid, maxillary and sphenoid air sinuses and cultures revealed Klebsiella pneumoniae which was sensitive to Cefuroxime. Despite medical and surgical treatment, left orbital swelling only reduced minimally. However after starting intravenous Dexamethasone the swelling dramatically improved. She completed 10 days of intravenous Dexamethasone. Upon discharge, she was given oral Dexamethasone 2mg daily for 2 weeks and completed 2 weeks of oral Cefuroxime and Metronidazole. Intraocular pressure normalised and vision recovered to 6/9. A repeat CT orbit 3 weeks later showed resolving preseptal and periorbital collection.

Facial dimensions of Malay children with repaired unilateral cleft lip and palate: a three dimensional analysis

Zreaqat M, Hassan R, Halim AS

Int J Oral Maxillofac Surg, 2012 Jun;41(6):783-8.
PMID: 22424709 DOI: 10.1016/j.ijom.2012.02.003

This comparative cross-sectional study assessed the facial surface dimensions of a group of Malay children with unilateral cleft lip and palate (UCLP) and compared them with a control group. 30 Malay children with UCLP aged 8-10 years and 30 unaffected age-matched children were voluntarily recruited from the Orthodontic Specialist Clinic in Hospital Universiti Sains Malaysia (HUSM). For the cleft group, lip and palate were repaired and assessment was performed prior to alveolar bone grafting and orthodontic treatment. The investigation was carried out using 3D digital stereophotogrammetry. 23 variables and two ratios were compared three-dimensionally between both groups. Statistically significant dimensional differences (P<0.05) were found between the UCLP Malay group and the control group mainly in the nasolabial region. These include increased alar base and alar base root width, shorter upper lip length, and increased nose base/mouth width ratio in the UCLP group. There were significant differences between the facial surface morphology of UCLP Malay children and control subjects. Particular surgical procedures performed during primary surgeries may contribute to these differences and negatively affect the surgical outcome.

Fulltext Gunshot-like wound caused by sling shot injury - a case report

Vinuthinee N, Azreen-Redzal A, Juanarita J, Zunaina E

Int Med Case Rep J, 2015;8:47-50.
PMID: 25709507 DOI: 10.2147/IMCRJ.S75198

We report a rare case of sling shot injury that presented with a gunshot-like wound with preseptal cellulitis, in a toddler. An 11-month-old Malay child presented with a gunshot-like wound over the forehead following sling shot injury. On examination, he had a deep circular laceration wound over the forehead, measuring 2.0 cm in diameter, with minimal bleeding. There was no obvious foreign body seen inside the wound and no palpable foreign body surrounding the wound. The gunshot-like wound was associated with left preseptal cellulitis. A skull X-ray showed a white opaque foreign body in the left frontal bone. Computed tomography (CT) scan of orbit and brain revealed a left comminuted fracture of the left orbital roof, and left frontal brain contusion with prelesional edema. Wound exploration was performed and revealed a 0.5 cm unshattered marble embedded in the left frontal bone. The marble and bone fragments were removed. The left preseptal cellulitis responded well to intravenous antibiotic and topical antibiotic.

Fulltext Posterior intraorbital metallic foreign body: a case discussion

Vinodh VP, Sellamuthu P, Harun RH, Zenian MS

Med J Malaysia, 2014 Apr;69(2):89-91.
PMID: 25241819 MyJurnal

Intraorbital foreign body (IOFB) has been a rare phenomenon in the cases of gunshot wounds and always represents a dilemma in medical management. In Sabah, this scenario is becoming common as there is still certain population in the interiors who owns self made guns for hunting. They either present with self inflicted gunshot injuries or after being mistakenly shot while hunting. There are very few articles on this topic especially when it is located posteriorly in the orbit and occurs without visual impairment. This case reports the challenges faced in the management of the patient with a posteriorly located metallic IOFB. The appropriate management of the patient is discussed based on several international literatures. Author describes a 37 years old male farmer, who was referred from a nearby district hospital after he sustained gunshot injuries to his face and scalp. Urgent computed tomography (CT) scan showed that bullet pellets were at the left orbital floor, the left mandible and the left frontal bone. All bullet pellets were located extracranially only without intracranial involvement. Patient clinically does not have any neurologic deficit and without any visual impairment, thus he refused any surgical intervention. As there is no proper guideline in managing such cases, decision was made based on evidences from international literatures. It was concluded that metallic IOFB located in the posterior orbit may be conservatively managed with observation and regular follow-ups as they are well-tolerated and does not cause much impact on visual deterioration unless inflammation, infection, optic neuropathy or functional deficit occurs. This avoids unnecessary surgery and prevents risk of iatrogenic injury to the eye.

Ghani Siti-Ilyana, Koh, Yi-Ni, Embong Zunaina

Journal of Biomedical and Clinical Sciences, 2018;3(1):19-24.
MyJurnal

Toxoplasmic optic neuropathy is rare and usually occurs monoocularly. This case report demonstrates a rare presentation of bilateral
juxtapapillary retinochoroiditis (Jensen disease) due to toxoplasma infection in
a young healthy patient. A 20-year-old lady presented with bilateral painless
blurring of central vision for 5 days duration. It was preceded by fever, upper
respiratory tract symptoms and headache. There was no history of contact or
being scratched by a cat. Visual acuity was counting fingers for the right eye
and 6/45 for the left eye. There was presence of relative afferent pupillary
defect in the right eye. Optic nerve functions were impaired bilaterally which
was severe in the right eye. Both eyes showed the presence of mild anterior
segment inflammation and vitritis. Fundus examination revealed juxtapapillary
retinochoroiditis bilaterally with swollen optic disc. Optical coherence
tomography (OCT) showed presence of intra-retinal and sub-retinal fluid at
macular area bilaterally. Serology for anti-toxoplasma Immunoglobulin G (IgG)
was positive with titre of 1450 IU/ml. Computed tomography scan (CT scan) of
brain and orbit was normal. A diagnosis of bilateral juxtapapillary
retinochoroiditis or Jensen disease was made. Oral azithromycin 500 mg daily
and guttae prednisolone 4 hourly for 6 weeks was commenced. Oral
prednisolone 50 mg daily (1 mg/kg/day) was added after completion of 1 week
of antibiotic and was tapered down within 5 weeks. There was improvement of
vision as early as 3 weeks post initiation of the treatment. Upon 6 weeks
completing the treatment, her vision has improved to 6/7.5 on both eyes with
resolution of optic disc swelling and sub-retinal fluid. Early recognition and
initiation of treatment in toxoplasma infection associated with juxtapapillary
retinochoroiditis usually result in good visual prognosis.

Fulltext Eyelid abscess with dacryocystitis due to burkholderia pseudomallei

Chee, Yik Chang

Borneo Journal of Medical Sciences, 2020;14(3):61-62.
MyJurnal

A 24-year-old female complained of a 2-week history of fever and right-eye swelling. There was no ocular pain, blurring of vision, or history of prior trauma to the affected eye. On examination, she was febrile and not in respiratory distress. The right lower eyelid appeared swollen with skin erythema (Figure 1), while the visual acuity was normal. The white cell count was 14.8 × 103/μL (normal range = 4 – 10 × 103/μL). Her liver and renal function tests were within the normal range. The abdominal ultrasonography revealed multiple splenic microabscesses, while chest radiograph was normal. Contrast-enhanced computed tomography of the orbit showed a right lower eyelid abscess with extension into the right nasolacrimal duct (Figure 2). Incision and drainage of the eyelid abscess were performed and the culture of the pus, as well as the blood, yielded Burkholderia pseudomallei. She received intravenous ceftazidime 2 g every 8 hours for 4 weeks, followed by oral trimethoprim-sulfamethoxazole for 20 weeks’ duration. The right eyelid abscess and splenic microabscesses resolved completely post-treatment. Please interpret the figures and suggest the provisional diagnosis.

Ting XW, Sothiraghagan S, W Md Kasim WM, Muhammed J

Cureus, 2020 May 24;12(5):e8259.
PMID: 32596077 DOI: 10.7759/cureus.8259

Objective To describe the patient demographics, clinical findings, investigations, surgical outcomes, and histopathological findings of seven cases of orbital solitary fibrous tumours. Method This was a retrospective review of seven cases of orbital solitary fibrous tumour, which were followed up in Hospital Serdang, a national oculoplastic centre, from years 2008-2017. Results This study included seven patients with ages between 21 and 35 years old; two were males and five were females. All seven patients presented with painless chronic unilateral proptosis. Radiological imaging of the orbit showed a localized contrast enhancing intraorbital mass. All patients underwent orbitotomy and excisional biopsy. Intraoperative findings showed a well-encapsulated and vascularized mass. Histological findings of spindle-shaped cells were noted. All cases had positive staining for cluster of differentiation (CD) 34, five were positive for CD 99, four were positive for B-cell lymphoma (BCL-2), and five patients had positive staining for S-100. Three of the patients did not have clear margins during the primary operation and subsequently had a recurrence within two years. Conclusion A solitary fibrous tumour is a rare mesenchymal tumour with a pleural origin. The orbit is the most common extrapleural site of the tumour and they are usually benign. Immunohistochemistry is important to differentiate it from other, more aggressive forms of orbital tumours. Regular follow-up is important to monitor for recurrence.

MyJurnal

A 64-year-old Malay gentleman alleged occupational injury when a malfunctioned metal hydraulic door hit on his face while unloading sand from his tipper-truck. Post-trauma, he complained of right eye (RE) pain and total loss of vision. On examination, noted RE visual acuity was unable to be assessed and left eye (LE) was 6/24 with pinhole 6/9. No eyeball could be seen in the right socket with superior orbital rim step deformity and left periorbital haema- toma. Computed tomography scan of the brain and orbit confirmed displaced right eye globe into the right anterior cranial fossa with right and left multiple orbital wall fractures. He then underwent successful right eye globe reposi- tioning. Traumatic orbital roof fracture is a rare condition. Repositioning of the eye globe was done to salvage the eye globe for a cosmetic reason and to avoid localised inflammatory reaction at the anterior cranial fossa.

PMID: 33981511 DOI: 10.7759/cureus.14392

Paediatric orbital cellulitis is a potential sight- and life-threatening condition. It is a serious infection in children that can result in significant complications, including blindness, cavernous sinus thrombosis, cerebral venous sinus thrombosis, meningitis, subdural empyema, and brain abscess. Of the patients with orbital cellulitis, 17% died from meningitis, and 20% of the survivors had permanent loss of vision. Therefore, the potential for sight- and life-threatening complications makes prompt diagnosis and early treatment very important. We report here a case of a two-year-old girl who presented with a three-day history of left periorbital swelling, preceded by left upper perioral swelling that extended upward to the left cheek and left lower lid and was associated with low-grade fever. The patient had been admitted and was treated as having left preseptal with facial cellulitis; the patient was started on intravenous amoxicillin/clavulanic acid (200 mg three times per day dose), and chloramphenicol ointment was applied to the periorbital area. On day 3, the condition worsened, and dental examination showed multiple dental caries, upper gum swelling and abscess, and mobility of teeth 61 and 62 (two baby teeth). Contrast-enhanced computed tomography (CECT) of the orbit, paranasal, and brain showed a left periosteal abscess collection extending to the inferomedial region of the orbit. Examination and tooth extraction were performed under general anesthesia. The intraoperative results showed the presence of a left upper gum abscess, which was possibly the primary source of infection. Clinical improvement was observed postoperatively. Orbital cellulitis can be a complication of a dental abscess. This case emphasizes the importance of primary tooth care in children. A lack of care can result in fatal complications.

A 42-year-old Malay gentleman presented with progressive painless blurring of vision on his left eye associated with ocular ache, redness and increasing proptosis. Examination revealed presence of relative afferent papillary defect with visual acuity of counting finger, and 6/6 on the right eye. Extraocular muscle movement of the left eye was restricted to ten percent in all directions. Computed tomography (CT) and magnetic resonance imaging (MRI) showed enhancing mass occupying the left orbital apex. Diagnosis of optic nerve sheath meningioma was made, and patient subsequently went for radiotherapy. His symptoms subsided completely, until he presented with similar visual complains, and fullness of the upper lid two years later. A repeated MRI showed enlargement of superior and lateral recti muscles with extension to lacrimal gland region. Biopsy of the lacrimal gland revealed inflammatory cells consistent of inflammatory pseudotumor. High dose systemic steroid was instituted, followed by slow tapering of oral steroid. His symptoms completely resolved, and latest visual acuity was 6/9, with no recurrence, to date.

Frontal mucocele is not commonly masked as upper lid abscess.A 72-year-old Chinese man with underlying hyperthyroidism complained of left upper eyelid swelling of 6 months duration. The swelling had persisted and worsen when intravenous antibiotic was changed oral type. Visual acuity on presentation was hand motion and reverse relative afferent pupillary defect was present. Because the swelling was large and resulted in mechanical ptosis and ophthalmoplegia, a CT imaging was performed, which showed huge left frontal mucocele eroding the supereromedial orbital rim. The left globe was displaced inferolaterally but there was no extension into brain parenchyma. Fundus examination showed pale optic disc with dull macula. Old laser marks were seen at peripheral fundus. Referral to ortholaryngologist was made and endoscopic sinus surgery and evacuation of mucopyocoele was done. Culture and sensitivity of the fluid showed no organism. He recovered well postoperatively with additional two weeks of antibiotics. We highlight the necessity of surgical drainage of mucocele, following a course of antibiotic.

44-year-old Malay lady presented with drooping of the right eyelid and worsening of left eye vision for one week duration. There was associated headache, periorbital discomfort and diplopia on left gaze. She previously had a history of recurrent optic neuritis affecting both eyes over a period of 12 years. On examination, there was right-sided partial ptosis and left exotropia. The adduction, abduction, elevation and depression of the right eye was limited. Left eye extraocular movements were full. The right eye visual acuity was 6/9, while the left eye visual acuity was perception to light, with a positive relative afferent papillary defect and a pale optic disc. The right optic disc was normal. There was reduced sensation in the trigeminal nerve distribution over the right side of the face. Neurological examination was otherwise normal. Magnetic resonance imaging of the brain and orbit revealed meningeal thickening with involvement of the right orbital apex and cavernous sinus. Blood investigations for infectious and autoimmune causes were unremarkable. She was diagnosed to have idiopathic hypertrophic cranial pachymeningitis and treated with systemic corticosteroids. The right eye extraocular motility improved, while the left eye visual acuity improved to counting finger. This case demonstrates that idiopathic hypertrophic cranial pachymeningitis may present as recurrent optic neuritis in the early phase, before radiological evidence of the disease is present. A high index of suspicion for the underlying cause is essential to prevent irreversible optic nerve damage due to recurrent optic neuritis.

Malaysian Journal of Paediatrics and Child Health, 2016;22(101):0-0.
MyJurnal

Background: A 9 year old boy presented with history of persistent headache and recurrent vomiting for 1 month post dental extraction. CT brain was performed for the possibility of space occupying lesion but it was normal. Subsequently, he was treated as migraine after exclusion of meningitis and intracranial lesion. Unfortunately, he developed 3rd, 4th and 6th cranial nerve palsy two weeks later. Repeated CT brain showed subtle finding and inconclusive. MRI brain performed at the time showed features suggestive of basal skull osteomyelitis with congestion of right orbit and optic nerve swelling. Case was referred to Paediatric Neurologist and he was diagnosed to have cranial nerve palsy secondary to basal skull osteomyelitis, post dental extraction.

Conclusion: Dental procedure is common among children, however basal skull osteomyelitis with cranial nerve palsy is a rare complication. Adequate treatment of dental infection post dental procedure is important to prevent this complication.

Strabismus is one of the most common ocular problems affecting the preschool population and the aim of strabismus surgery is to correct abnormal alignment of the eyes. A 5-year-old girl with strabismus underwent an uneventful surgery and was discharged on the same day with topical medications. Two days later, she returned with a painful right lower eyelid swelling, eye discharge and fever which started 1 day post-surgery. She was admitted for intravenous (IV) antibiotic. Symptoms initially improved after 24 hours of treatment, but later she had worsening eyelid swelling. An urgent CT scan of the orbit showed a right lower lid abscess with orbital cellulitis. Subsequently an examination under anaesthesia (EUA) and incision and drainage (I&D) of the lower lid abscess were performed. Culture from the pus grew Community Acquired Methicillin-resistant Staphylococcus aureus (CA-MRSA), sensitive to Vancomycin. At day 2 post I&D she subsequently developed another episode of localised right lower lid swelling. Another EUA was done but showed the lower lid and wound was free of pus. She was later found to have a toxic reaction to topical Gentamicin and hence this medication was stopped. She responded well to treatment and was discharged after completing her IV antibiotics. At 14 months outpatient follow up, she was well and orthophoric in primary gaze. While treating a disease, we should be opened to all possibilities and not to treat with multiple antibiotics once susceptibility is known

Insect succession associated with a hanging pig carcass placed in an oil palm plantation in Malaysia

Heo CC, Sallehudin Sulaiman, Hidayatulfathi Othman, Baharudin Omar, Jeffery J, Kurahashi H

Sains Malaysiana, 2010;39.

This study was carried out in an oil palm plantation in Tanjung Sepat, Selangor in September 2007 by using pigs (Sus scrofa L.) as a carcass model in a forensic entomological research. A 2.5 month old pig (10 kg) which died naturally was hanged on a palm tree to observe the insect succession and decomposition stages. Observation was made for 16 days; one afternoon visit per day and all climatological data were recorded. On the first day, adult muscids of Ophyra spinigera Stein and Musca domestica L. were observed, however no blowfly (Calliphoridae) activities were sighted. Fly eggs wer seen on the second day on both sides of the face, inside nostrils and genitourinary area. Adults of Chrysomya megacephala Fabricius and Chrysomya rufifacies (Macquart) congregated on the head and anal areas. Adult flies and maggots (first and second instars) were observed in the mouth and anus of the pig on the third day of hanging. Adult yellow jackets (Vespidae) and spiders (Arachnida) were found preying on some adult flies. Rove beetles (Staphilinidae) were also discovered on the pig carcass. Only a few ants (Formicidae) were sighted. Maggot masses were found in eye orbits, neck, and genital organs on the fourth day of hanging and some maggots were seen falling down to the ground. The dominant maggot species identified on this day was Ch. megacephala. On the sixth day, the head, neck, and anus were in the stage of active decay. Maggots of Ch. rufifacies were abundant on the seventh day and was the dominant species. On day eight the carcass fell onto the ground. Chrysomya rufifacies maggots were found underneath the pig carcass and they started to migrate and pupated under the soil. On the tenth day, third instar Op. spinigera maggots were found under the carcass. The rate of carcass decomposition slowed down and became stable from tenth day onwards to the sixteenth day of decomposition. Thereafter, most of the remaining parts of the body remained dried and devoid of any insects.
