Objective: To describe a patient with hemi-retinal artery occlusion following methanol toxicity.

Methods: Observational case report.

Results: We report a case presented with an acute altitudinal visual field loss in the right eye following consumption of illicit alcoholic drink. In fundus photography, a well demarcated superior hemi-retinal whitening with foveal sparing was noted. Careful inspection of the optic nerve head in the right eye revealed that there was no main trunk of the central retinal artery anterior to the lamina cribrosa. Two separately emerging superior and inferior arterial trunks were noted. In fundus fluorescein angiography, earlier dye filling in the territory of the superior arterial trunk compared to the inferior arterial trunk was evident.

Conclusion: Hemi-central retinal occlusion may happen as an ocular consequence of methanol toxicity in patients with a proximal bifurcation of the central retinal artery.

Breast carcinoma metastasis can involve any ocular structures, but involvement of the optic nerve is extremely rare. Choroidal metastasis is usually multifocal as well as bilateral and occurs late. We report an unusual initial presentation of metastasis from breast cancer; unilateral infiltrative optic neuropathy with concurrent choroid metastatic deposits in an adequately treated middle-aged female. Our present case, wherein for the first time in the literature, we illustrated unilateral infiltrative optic neuropathy and choroidal metastatic deposits secondary to breast carcinoma, will increase our knowledge about the various potential ocular presentations of this relatively common malignant disease.

Self-enucleation, also known as Oedipism, is a rare form of ocular trauma. The objective of this clinical case report is to highlight the importance of diagnosing this unusual injury and thus ensuring its appropriate management. We herein describe a case of a 58-year-old man who presented to hospital with a bleeding left eye. Initially, limited history was provided, however, on further enquiry it was revealed that he had paranoid schizophrenia. The patient eventually had to be sectioned with assistance from the Police and Psychiatry team, upon discovery of self-inflicted mechanism of injury. Subsequently, the patient had evisceration of the left eye and afterwards, demonstrated insight into the pre-operative problems. Literature review emphasizes the importance of close cooperation required between medical specialities to ensure that the underlying cause, usually schizophrenia, is managed in conjunction to the eye injury in order to provide optimum care for the patient.

Objective: To describe an interesting case of miliary tuberculosis mimicking retinoblastoma. Method: A retrospective case report. Result: The twin brother of a known case of retinobastoma presented with headache. On fundus examination, multiple yellowish-white lesions were noted in both eyes. Magnetic resonance imaging of the brain showed multiple enhancing lesions. A diagnosis of miliary tuberculosis was made and anti-tubercular therapy was started. Conclusion: Ocular tuberculosis can mimic retinoblastoma and lead to diagnostic dilemma especially in cases with family history of retinoblastoma.

Objective: Ocular surface squamous neoplasia (OSSN) is the most common type of non-melanocytic ocular surface tumor. Conjunctival intraepithelial neoplasia (CIN) is a type of OSSN that be medically managed by either topical interferon alpha-2b (IFN α-2b), 5-fluorouracil (5-FU), or mitomycin C. While a paradoxical response to IFN α-2b in the HIV population has been reported, we report a case of a paradoxical response in an immunocompetent individual. Methods: A 65-year-old immunocompetent female presents to the clinic with CIN. Results: She is started on topical IFN α-2b, resulting in an unexpected hypopyon, increased corneal epithelial defect, and increased size of the lesion. Switching to topical 5-FU resulted in decreasing size of the CIN lesion and resolution of the epithelial defect. Conclusions: Topical IFN α-2b can produce a paradoxical worsening of CIN lesions in some patients. Providers should be aware of this reaction, as well as the presenting signs and symptoms, to make appropriate treatment changes when treating CIN.

Background: Microbial keratitis is an important cause of ocular morbidity, with emerging organisms and drug resistance posing a real threat to vision of patients. Case presentation: A 30-year-old female presented with infective keratitis in the left eye. She had been using rose nectar as home remedy for her ailment. With no improvement in her symptoms, she presented to the eye emergency department, where she was started on empirical therapy with moxifloxacin, which was shifted to levofloxacin eye drops after the antimicrobial susceptibility test results came in. Microbiological examination revealed infection with rare gram-negative bacilli Citrobacter koseri. The patient responded well to the treatment with 1.5% levofloxacin eye drops and her vision improved from 20/120 to 20/30 over a course of 3 months. Conclusion: Treatment of microbial keratitis with those antibiotics that the organism is most sensitive to is of paramount importance today, where we often find patients on a cocktail of eye drops, which leads to further resistance and vision deterioration. Culturing of cornea scrapings and antimicrobial susceptibility testing of the isolated organism is now the standard guideline to be followed in the investigation of microbial keratitis.
