Catalase activity was evaluated in Long Evans rat retina after ischemia and reperfusion. Ischemia was induced by ligation of the optic nerve and vessels. Rats were sacrificed after 15 and 120 min of reperfusion, respectively. Catalase activity was assessed by Claiborne's method and was expressed as U/mg of protein. In the first group, retinas of each animal(More)
The heat shock protein 70 (HSP-70) mRNA level was evaluated in Long Evans rat retinas after ischemia and after reperfusion following ischemia. Retinal ischemia was induced by ligation of the optic nerve and vessels. Rats were sacrificed after 90 min of ischemia or 120 min of reperfusion following ischemia. Retinas were dissected. Total mRNA was extracted(More)
Purpose. To precise the natural cc~urse of extensive submacular hemorrhages in age-related macular degeneration (AMD). &&Q&. 68 eyes (62 patients) with subretinal hemorrhage larger than 1 disk diameter extending beneath the fovea were retrospectively reviewed. All patients, older than 55 years, presented AMD features and had no previous laser treatment.(More)
We reported on the case of a seven years-old boy suffering from an acute unilateral proptosis. Diagnosis of orbital lymphangioma was made with Magnetic Resonance Imaging (MRI) showing an intra-tumoral hemorrhage in a vascular tumor unrelated to general circulation. Authors underlined the interest of MRI due to its unique ability to characterize hemorrhage(More)
Purpose: Capsular related complications may occur during and/or following cataract s”rPew. Methods: We used endocapsular PUMA rings (EPR) to prevent such complications in eyes with pre or peroperative zonular c’ehiscence, high myopic eyes and eyes witl: exfoliation syndrome which have weak zonoles. EPR can be implanted easily through the phaco-incision(More)
