Central retinal artery occlusion following blunt trauma a 19-year-old patient presented with complaints of severe loss of vision in the right eye following a high pressure compressor gas injury of 1 day duration. External ocular examination revealed ecchymosis in the right eye and relative afferent pupillary defect. Fundus examination showed white-out retina and a cherry red spot at the macula in the right. A clinical diagnosis of right central retinal arterial obstruction (CRAO) was made. CRAO in young is a rare disease usually found in patients with cardiac embolic diseases, coagulopathies or systemic vascular inflammations and rarely following trauma. Despite active intervention the visual loss persisted. Hence the case report.
Triamcinolone is a corticosteroid that is used to treat many ophthalmic diseases. Recently, its use has been advocated to aid in visualization of transparent tissue in ophthalmic surgery. It can be used in anterior segment surgery to help manage vitreous loss during complicated cataract surgery. It has been used to visualize the posterior cortical vitreous during pars plana vitrectomy. In addition, it can be useful in the visualization and peeling of the internal limiting membrane. Triamcinolone has been advocated in surgical repair of proliferative vitreoretinopathy both for its visualizing properties and its anti-inflammatory properties. Overall, triamcinolone use in surgery is safe with low incidence of complications including elevated intraocular pressure, cataract and endophthalmitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
