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.
