We report a case of bilateral peripheral retinal neovascularization and chronic idiopathic myelofibrosis in a 69-year-old man. Ophthalmic examination revealed peripheral retinal nonperfusion with retinal neovascularization in both eyes and vitreous hemorrhage in the right eye. Fluorescein angiography of both eyes showed a marked midperipheral and peripheral avascular retina temporally with arte...
purpose: to compare the effect of tissue plasminogen activator (tpa) and aspirin in patients with central retinal vein occlusion. methods: a prospective interventional study was conducted on patients with central retinal vein occlusion of less than 28 days' duration. patients in the tpa group received 100 μg intravitreal tissue plasminogen activator and the patients who declined intravitre...
PURPOSE We report a newly developed device to fragment thrombi in retinal vein occlusion. METHODS The new instrument consists of a 23-gauge (G) pipe and a 37-G needle with an internal wire. A total of 40 porcine eyes were used; 20 eyes for experiments in the branch retinal vein (BRV group) and 20 eyes for experiments in the central retinal vein (CRV group). We placed 25-G 3-port trocars, and ...
Retinal vein occlusion is an eye condition commonly seen by retinal specialists. It is second only to diabetic retinopathy as a cause of visual loss due to retinal vascular disease. There are two forms of retinal vein occlusion, branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO). While there are similarities in the pathogenesis and clinical nature of these two events...
