    The aim of this study was to determine the predictors of post-traumatic enophthalmos (PE) in relation to the internal orbital changes following pure orbital blowout fractures. The design was a 10-year retrospective cross-sectional study analysing 629 medical records and computed tomography (CT) data of patients with orbital fractures from January 2008 to January 2017. Demographic, etiology, co-morbidity and clinical characteristics were obtained from the medical records. Assessment of the PE, fracture site and size, intraorbital structures and muscle change were performed using the Digital Imaging and Communications in Medicine (DICOM) viewer software, OsiriX v5.8.2. Of the 629 patients with orbital fractures, 87 were pure orbital blowout fractures. Demographic pattern showed that males outnumbered females in the series, with male: female ratio of 5.7:1. The mean age was 37.2 ± 14.7 and the main etiology was motor vehicle accident. Orbital floor fracture was the most common fracture location (67.8%). The involvement of the posterior ledge and inferior orbital fissure showed statistical significant difference with PE (Fisher's exact test, p = 0.03). Binary logistic regression showed that after controlling for age, patients with fracture size of more than 150 mm2 had three times the odds of sustaining a PE, (adjusted odds ratio (AOR) = 3.01 (95% CI 1.17-7.92). Fracture size larger than 150 mm2 was a radiological predictor of PE. Additional research investigating further on the role of concurrent fracture of the posterior ledge and inferior orbital fissure is advocated.

    Sinonasal tumors may grow to considerable size before presentation and in view of their relation to the base of skull, orbit, cranial nerves and vital vessels; a precise diagnostic and therapeutic planning is needed to achieve the optimal results. We report a case who presented with unilateral nasal blockage, rhinorrhea and episodes of epistaxis which diagnosed as sinonasal inverted papilloma and angiofibroma.

    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.

    In this paper, we report three cases of orbital rhabdomyosarcoma in different age groups with different histopathologic types. Case 1 is a 10-year old Malay boy who presented with painless proptosis of the left eye. Magnetic resonance imaging (MRI) showed soft tissue mass arising from the lateral rectus muscle. Tissue biopsy revealed rhabdomyosarcoma of embryonal type. Case 2 is a 32-year old Malay man who presented with a progressive left eye proptosis associated with pain and redness. Computed Tomography (CT) scan showed a retrobulbar mass extending medially in the left orbit. Meanwhile, biopsy showed rhabdomyosarcoma of pleomorphic type. Case 3 is a 67-year old Malay woman who presented with proptosis and fungating growth of left orbital region, epistaxis and nasal blockage. CT scan revealed an ill-defined mass filling up the left orbital cavity. Biopsy showed rhabdomyosarcoma of alveolar type. Rhabdomyosarcoma is the most common in childhood but it should be considered as a differential diagnosis of orbital tumours irrespective of age.

    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.

    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.

    Comet Lulin was discovered by Lin Chi-Sheng and Ye Quanzhi using the 16-inch telescope at Lulin Observatory in Nantou, Taiwan in 2007. According to Brian Marsden of the Smithsonian Astrophysical Observatory, it reached its perihelion on 10 January 2009 at a distance of 113 million
    km from the Sun. It moves in a very nearly parabolic retrograde (‘backwards’ compared to the movement of the planets) orbit at an inclination of 1.6 degrees from the ecliptic (“Newfound Comet Lulin to Grace Night Skies”). http://www.space.com/spacewatch/090206-ns-cometlulin.html). It passed nearest to the Earth at a distance of 61 million km on 23 February 2009.

    Comet 17P/Holmes was discovered by Edwin Holmes on 6 November 1892 while he was conducting regular observations of the Andromeda Galaxy (M31). Calculations using observation of its orbits established the perihelion date as 13 June and the orbital period as 6.9 years. The 1899 and 1906 appearances were observed, but the comet was only seen again in 1964. The comet has since been
    observed on every subsequent return.

    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.

    Enucleation and evisceration are the most common surgical procedures that are performed to manage tumor, trauma, and infection. Given the consequences of surgical intervention, the conditions of the remaining eye socket may affect future prosthetic rehabilitation. A custom-made ocular prosthesis can be used to help restore the esthetics and functional defects and to improve the quality of life of patients with such conditions. An assessment must be performed on the prosthetic outcome before rehabilitation. The etiology of defect, type of surgery, condition of the remaining socket, and patient's age should all be considered. This report discusses three different etiological eye defects that have undergone enucleation and evisceration and describes the factors that have a significant role in the esthetic and functional outcome of the prosthesis. This report should serve as a helpful aid for maxillofacial prosthodontists to understand the primary objective of rehabilitating each eye defect and to meet patient expectations.

    Enucleation is the removal of the entire globe of the eye and a portion of the optic nerve, while evisceration involves the removal of the contents of the globe leaving the sclera, extraocular muscles, and optic nerve. Following enucleation or evisceration, intraorbital implants are routinely placed to enhance the prosthetic outcome in addition to restoring the lost orbital volume. Current practice employs intraorbital implants made of nonporous silicone, hydroxyapatite, or porous polyethylene. Intraorbital implant selection and placement, being a highly demanding procedure in terms of knowledge, skill, and expertise, may be associated with a multiplicity of technical and surgical errors. Complications are usually minimal with these implants, but they do occur. The literature reveals many articles related to intraorbital implants, their benefits, and complications; however, the literature regarding the effect of various intraorbital implant situations on the subsequent prosthetic rehabilitation is markedly scarce. Moreover, the need for interdisciplinary surgical and prosthetic interventions required for successful rehabilitation in cases of compromised implant situations has been underemphasized. Hence, this review aimed to evaluate the effect of different intraorbital implant situations on ocular rehabilitation and the required interdisciplinary surgical and prosthetic treatment approach for rehabilitation of enucleated/eviscerated sockets with compromised implant situations, to provide a critical appraisal, and to present a simplified management strategy.

    Our aim was to examine the relations between type and site of the fracture, age of the patient, and the management and outcomes, among children diagnosed with orbital fractures at the Women's and Children's Hospital, Adelaide, during a 10-year period from 1 January 2003 to 31 December 2012. The records of 41 children whose ages ranged from 8 months to 15 years were analysed. There was a male predominance (n=33). Two most common fractures were orbital floor and multiwalled fractures, with medial wall as the second most common site. The most common cause of injury was sport, more often with increasing age. In contrast, falls were more common among young children. Fractures of the orbital roof were more common among young children, all of ours being in children 10 years old or less. Lateral wall fractures were also more common among young children and declined in frequency with increasing age. In contrast, fractures of the orbital floor and medial wall can occur at any age, though those of the medial wall were more common among older children. As children grow their behaviour and activities change, and the mechanism by which they become injured also changes. Growth and development of the craniofacial skeleton lead to differences in the patterns of fractures with age. Fractures of the orbital roof and lateral wall are more common among young children, while those of the orbital floor and medial wall can occur at any age.

    BACKGROUND: Orbital cavernous hemangiomas (OCH) are the most common adult orbital tumor and represent an ideal index lesion for endonasal orbital tumor surgery. In order to standardize outcomes reporting, an anatomic-based staging system was developed.

    METHODS: An international, multidisciplinary panel of 23 experts in orbital tumor surgery was formed. A modified Delphi method was used to develop the cavernous hemangioma exclusively endonasal resection (CHEER) staging system with a total of 2 rounds being completed.

    RESULTS: Tumors medial to a plane along the long axis of the optic nerve may be considered amenable for an exclusively endonasal resection. In select cases, tumors may extend inferolaterally if the tumor remains below a plane from the contralateral naris through the long axis of the optic nerve (ie, plane of resectability [POR]). This definition reached consensus with 91.3% of panelists in agreement. Five stages were designed based on increasing technical resection difficulty and potential for morbidity. Stages were based on the relationship of the tumor to the extraocular muscles, the inferomedial muscular trunk of the ophthalmic artery (IMT), and orbital foramina. Staging by anatomic location also reached consensus with 87.0% of panelists in agreement. Size was not included in the staging system due to the lack of agreement on the contribution of size to resection difficulty.

    CONCLUSION: Endoscopic orbital tumor surgery is a nascent field with a growing, yet heterogeneous, body of literature. The CHEER staging system is designed to facilitate international, high-quality, standardized studies establishing the safety, efficacy, and outcomes of endonasal resection of OCH.

    This study documented details of the dentitions, skulls and other skeletal remains of Crocodylus porosus and Tomistoma schlegelii, from western part of Sarawak, Malaysian Borneo. The remains of both reptiles were exhumed, followed by standard cleaning procedures and then detail morphological assessments were carried out accordingly. Both species show similar structure of vertebral columns, but T. schlegelii has the following unique structures: a long and narrower snout, D-shaped eye sockets, long and sharp pointed protruding quadratojugal bones, straight maxillae and dentary, a smooth surfaced skull, elongated triangular suborbital fenestrae, round shaped internal nares and visible supraoccipital from a dorsal view. C. porosus has heterodont dentition with blunt-pointed and irregular size of teeth whereas T. schlegelii has almost homodont dentition with sharp and similar size teeth. This is the first collection of teeth, skulls and other skeletal remains of both species obtained from Sarawak, and the materials have been used regularly to educate the public through science exhibitions, hoping they will spark the interests of young budding scientists to be involved in wildlife taphonomic studies in the future.

    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.

    Orbital fractures and the concomitant soft tissue injuries within the bony orbit result in well-recognized complications such as diplopia and enophthalmos. Guidelines for timing and indications for surgery for achieving an optimal outcome remain elusive. This study examined the effects of timing and fracture type on the outcome of orbital fracture repair.

    Epsilon-and-mu-near-zero (EMNZ) metamaterial structure inspired UHF antenna for nanosatellite has been proposed in this paper. The antenna consists of 3 × 2-unit cell array on the ground plane and a meander line radiating patch. Coaxial probe feeding technique has been obtained to excite the antenna. The meander line enables the antenna to resonate at lower UHF band and the metamaterial array is used to make the resonant frequency stable by reducing the coupling effect with metallic nanosatellite structure. The metamaterial structure exhibits EMNZ characteristics from 385 MHz to 488.5 MHz, which facilitates stable resonant frequency and higher antenna efficiency when embedded with nanosatellite structure. The proposed EMNZ inspired antenna has achieved measured impedance bandwidth (S11 orbit nanosatellite communications.

    Acute ptosis due to preseptal cellulitis requires urgent medical attention, as the infection can extend posteriorly into the orbit, leading to significant visual and cerebral complications. We report a case of a 58-year-old woman with uncontrolled diabetes mellitus presenting with acute ptosis due to preseptal cellulitis. After initial resolution of fever with intravenous amoxicillin-clavulanate, she experienced a seizure due to cerebral abscess a week later and was treated with intravenous ceftriaxone. Preseptal cellulitis is usually treated on an outpatient basis with oral antibiotics, as it rarely extends posteriorly to cause cerebral complications. We wish to highlight the importance of admitting patients with preseptal cellulitis in patients with uncontrolled diabetes for intravenous antibiotics due to the potential for visual and cerebral complications.
