An 18-year-old Malay gentleman was noted to have profound bilateral blurred vision for one month duration, associated with loss of weight, appetite, low grade fever and abdominal distension. Visual acuity on presentation was 6/60 on the right, counting finger on the left with no afferent pupillary defect. Anterior segments were unremarkable. Vitreous cells were occasional bilaterally. Fundus revealed multiple choroidal and sub-retinal Roth spots with areas of pre-retinal and intra-retinal haemorrhages, involving the macula in the left eye. Vessels were dilated and tortuous in all quadrants of the right eye. Many areas of capillary fall out at peripheral retina were demonstrated in fundus fluorescein angiogram. Further systemic and laboratory review confirmed the diagnosis of CML and chemotherapy was initiated. Both eye ischaemic retinopathy secondary to CML was confirmed and scatter pan retinal photocoagulation was performed bilaterally. Good improvement in vision noted during subsequent follow up to 6/24 on the right, 6/60 on the left. High levels of suspicion and accurate early recognition of fundus changes are vital in these types of cases to ensure the institution of prompt treatment.

A 65-year-old lady complained of occasional flashes of light over her left eye for 2 months. She was referred for ocular assessment after she underwent refractive assessment at the optometrist. On examination, best corrected visual acuity in both eyes was 6/9. Both eyes anterior segments were normal, with normal intraocular pressure. The pupils were equal with no relative afferent pupillary defect. Left eye fundus examination was normal. On the contrary, the "normal" right eye fundus examination revealed a huge, well-circumscribed hypo-pigmented elevated choroidal mass. B scan ultrasonography of the right eye showed a mushroom-shaped intraocular mass. Magnetic resonance imaging showed an intraocular lesion. Comprehensive systemic examination and investigations to rule out distant primary malignancy were unremarkable. A provisional diagnosis of right eye primary choroidal melanoma was made. Despite good vision in the affected eye, she underwent right eye enucleation in view of the large intraocular mass. The diagnosis was confirmed by histopathological examination.

Kiu KH, Hanizasurana H, Zunaina E

Int Med Case Rep J, 2015;8:255-8.
PMID: 26527902 DOI: 10.2147/IMCRJ.S91323

A 22-year-old Malay female presented with left eye floaters for 2 weeks, associated with temporal visual field defect and metamorphopsia for 3 days. She has a guinea pig and a hedgehog at home, but denied being bitten or scratched by them. Her visual acuity at presentation was 6/12 on the left eye and 6/6 on the right eye. Her left eye relative afferent pupillary defect was barely positive with mild anterior chamber reaction. Fundus examination of the left eye showed mild vitritis, swollen optic disc with macular star, crops of active choroidal lesions at superonasal retina with a linear arrangement in the form of migratory track nasally. However, there were no nematodes seen on fundus examination. Investigations showed normal full blood count with no eosinophilia and positive serology test for Bartonella henselae. She was diagnosed to have dual infection - diffuse unilateral subacute neuroretinitis (DUSN), based on the presence of crops of choroidal lesions with migratory track, and cat scratch disease (CSD) based on a positive serological test. She was treated with oral albendazole 400 mg 12 hourly for 6 weeks for DUSN and oral doxycycline 100 mg 12 hourly for 4 weeks for CSD. Focal laser had been applied to the area of migratory track in the left eye. Her left eye vision improved to 6/6 at 1 month after treatment, with resolution of neuroretinitis.

PMID: 31205829 DOI: 10.7759/cureus.4407

Purpose To describe the visual presentation and factors affecting visual outcome in pediatric patients treated for craniopharyngioma at a referral center in the East Coast states of Peninsular Malaysia. Methodology A retrospective review of medical records of children aged 17 years and below who had been treated for craniopharyngioma in Hospital Universiti Sains Malaysia from January 2014 to December 2018. The data collected included age, gender, presenting symptoms and duration, visual acuity, visual fields, color vision, light brightness, relative afferent pupillary defects, fundus examination and cranial nerves examination. The best corrected visual acuity during presentation, and after a one-year post-operative period, was documented. Records on investigations, surgical procedures, therapeutic modalities and recurrences were also reviewed. Results A total of 11 pediatric patients (22 eyes) were recruited. Fifty percent presented with optic atrophy. The mean duration of the onset of symptoms before consultation was 22.3 (24.5) months. A final best corrected visual acuity of 6/12 (20/40) or better was observed in 50% of the patients. There was a statistically significant association between presenting visual acuity, optic nerve function and visual field defects, and the final visual outcome. Conclusions Visual presentations in our study were fairly similar to previous reported studies. One-third presented late with permanent visual loss. Almost half had significant visual impairment after one-year post-operative period. Significant associations were observed between presenting visual acuity, duration of symptoms, impairment of optic nerve function tests, and visual field defects during presentation, and final visual acuity at one year after treatment.

Fulltext Optic nerve infiltration in adult acute lymphoblastic leukaemia (ALL)

Muhamad-Amin, R., Nur Hasnida Gani, Liza-Sharmini, A.T., Zamli, A.H.

Journal of Biomedical and Clinical Sciences, 2018;3(2):22-25.
MyJurnal

Acute lymphoblastic leukemia (ALL) is the most common
childhood leukaemia. It is a malignant neoplasm caused by the proliferation of
poorly differentiated precursors of the lymphoid cells. It is relatively
uncommon in adult. In adult ALL, central nervous system (CNS) involvement
is associated with poor prognosis. The incidence of CNS involvement has
been reported between 7% and 15 %. We report a case of optic nerve
infiltration in ALL in a 49 years old gentleman. He was diagnosed with
precursor-B ALL. He was treated with chemotherapy and CNS prophylactic
regime. He presented with sudden left eye loss of vision for one-day duration
with history of right eye inferior visual field loss for the past three months. His
visual acuity was no perception to light on the left eye and 6/9 on the right
eye. There was marked left relative afferent pupillary defect. The right eye
showed decreased in optic nerve function with inferior visual field defect.
Anterior segment examination was unremarkable in both eyes. Left optic disc
appeared normal but the right optic disc was pale. Blood investigation
showed no sign of infection or haemoconcentration. Cerebral spinal fluids
examination revealed abundant of white cells and blast cells. Magnetic
resonant imaging showed bilateral optic nerve enhancement suggesting of
bilateral optic nerves infiltration. He was started on a new regime of
chemotherapy followed by cranial radiotherapy. Unfortunately, he succumbed
to death due to septicaemia. There are variations in clinical presentation of
optic nerve infiltration in leukaemic patients. Normal appearance of optic disc
may not exclude the possibility of infiltration by malignancy. Assessment of
the optic nerve function and imaging is helpful for the detection of leukaemic
infiltration. Early detection of optic nerve infiltration is important for initiation or
change of therapy to prevent mortality.

PMID: 22536041 DOI: 10.2147/OPTH.S29806

We report a case of diffuse unilateral subacute neuroretinitis in a young boy with no clinical visualization of nematode. The diagnosis was made based on clinical findings and detection of Toxocara immunoglobulin G by Western blot test. An 11-year-old Malay boy presented with progressive blurring of vision in the left eye for a duration of 1 year. It was associated with intermittent floaters. Visual acuity in the left eye was 6/45 and improved to 6/24 with pinhole. There was positive relative afferent pupillary defect, impaired color vision, and presence of red desaturation in the left eye. There were occasional cells in the anterior chamber with no conjunctiva injection. Posterior segment examination revealed mild-to-moderate vitritis and generalized pigmentary changes of the retina with attenuated vessels. The optic disk was slightly hyperemic with mild edema. There was presence of multiple, focal, gray-white subretinal lesions at the inferior part of the retina. Full blood picture results showed eosinophilia with detection of Toxocara immunoglobulin G by Western blot test. Investigations for other infective causes and connective tissue diseases were negative. The diagnosis of diffuse unilateral subacute neuroretinitis secondary to Toxocara was made based on clinical findings and laboratory results. He was treated with oral albendazole 400 mg daily for 5 days and oral prednisolone 1 mg/kg with tapering doses over 6 weeks. At 1 month follow-up, the inflammation had reduced, and multiple, focal, gray-white subretinal lesions were resolved; however there was no improvement of vision.

Fulltext Frontal mucocele masked as upper lid abcess- a case report

Ng, WL, Umi Kalthum MN, Jemaima CH, Norshamsiah MD

Journal of Surgical Academia, 2016;6(1):43-45.
MyJurnal

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.

A 21-year-old Chinese gentleman with no known medical illness, presented with a history of right painless blurring of vision with central scotoma of two weeks duration. He also had a history of multiple episodes of seizures prior to presentation. Visual acuity was 1/60 with unremarkable anterior segment findings and no relative afferent pupillary defect. Fundus examination of the right eye revealed dilated and tortuous retinal veins with multiple retinal capillary hemangiomas and sub retinal hard exudates at the macula with edema. A diagnosis of Von Hippel Lindau disease was made when a posterior fossa mass suggestive of hemangioblastoma with obstructive hydrocephalus was seen on computed tomography of the brain. Craniotomy with nodule excision was performed. The retinal capillary hemangiomas were treated with the combination of laser photocoagulation and intravitreal Ranibizumab injections. Visual acuity subsequently improved to 6/36.

A 42-year-old Chinese man, known case of renal cell carcinoma with lung metastasis, was referred to Universiti
Kebangsaan Malaysia Medical Centre for left eye blurring of vision for one month duration, which was worse upon
waking up in the morning and cleared up after 1-2 hours. On examination, visual acuities were 6/6 in both eyes. No
relative afferent pupillary defect. Left fundus showed inferonasal retinal detachment without macular involvement.
No retina break, no retinitis and no choroidal lesion seen. Right eye examination was normal. Optical coherence
tomography (OCT) of left eye showed subretinal fluid temporal and inferior to optic disc. Fundus fluorescein
angiography (FFA) left eye showed hypofluoresence in early phase but hyperfluorescence with pin point leakage in
late phase over inferonasal quadrant. Indocyanine green (ICG) showed early hypofluoresence with late pin point
hyperfluoresence in the same quadrant. A clinical diagnosis of exudative retinal detachment due to choroidal
metastasis secondary to renal cell carcinoma was made. The patient was planned for cyber-knife radiotherapy of his
left eye but unfortunately we lost the follow up. High index of suspicion and relevant investigation are needed for
patients with visual complaints and history of renal cell carcinoma to diagnose choroidal metastasis.

Zuhaimy H, Aziz HA, Vasudevan S, Hui Hui S

GMS Ophthalmol Cases, 2017;7:Doc04.
PMID: 28194321 DOI: 10.3205/oc000055

Objective: To report an aggressive case of extranodal natural killer/T-cell lymphoma (NKTCL) of the ethmoid sinus presenting as orbital cellulitis Method: Case report Results: A 56-year-old male presented with right eye redness, reduced vision, and periorbital swelling for 5 weeks duration associated with a two-month history of blocked nose. The visual acuity of the right eye was 6/18. The eye was proptosed with periorbital oedema and conjunctival chemosis. The pupil was mid-dilated but there was no relative afferent pupillary defect. The fundus was normal. The extraocular movements were restricted in all directions of gaze. Nasal endoscopy revealed pansinusitis that corresponded with CT scan orbit and paranasal sinuses findings. Despite treatment, he showed no clinical improvement. Ethmoidal sinus biopsies performed revealed extranodal NKTCL. Further imaging showed involvement of the right orbital contents and its adnexa with intracranial extension into the right cavernous sinus and meninges over right temporal fossa. The patient underwent chemotherapy. However he succumbed to his illness two months after the diagnosis. Conclusion: Extranodal NKTCL is a great mimicker. This case demonstrated how an acute initial presentation of extranodal NKTCL can present as orbital cellulitis with pansinusitis.

Optic Nerve Infiltration in Systemic Metastatic Retinal Lymphoma (SMRL): Multimodal Imaging and Challenges in Diagnosis

Mohd Fauzi Yap MFB, Mohd Zain A, Tumain NR, Palaniappan S, Nasaruddin RA, Md Din N

Ocul Immunol Inflamm, 2020 Sep 24.
PMID: 32967510 DOI: 10.1080/09273948.2020.1800050

A 45-year-old man was diagnosed with diffuse large B-cell lymphoma stage IV which was confirmed by celiac lymph node biopsy. He subsequently completed six cycles of R-CHOP chemotherapy. Six months later, he presented with panuveitis OU with positive relative afferent pupillary defect OD. OCT revealed hyper-reflective lesions and irregularity of the retinal pigment epithelium OU. Fundus fluorescein angiogram shows hyper-auto fluorescence and granular changes on the retina. A month later, he developed swollen optic disc OD and hemorrhagic retinitis OU and treated as presumed CMV retinitis. Anti-TB was started after a positive Mantoux test. He finally consented for a vitreous biopsy which showed atypical lymphoid cells highly suggestive for vitreoretinal lymphoma and subsequently received intravitreal methotrexate OU.
CONCLUSION: Optic nerve infiltration in systemic metastatic retinal lymphoma may have initial occult signs but with profound visual loss. Ocular infections like CMV retinitis and tuberculosis may mask and delay the diagnosis in immunocompromised patients.

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.
