Correlation Between Ischemic Index of Retinal Vein Occlusion and Oxygen Saturation in Retinal Vessels.

Purpose: To evaluate the relationship between the ischemic index and the oxygen saturation in retinal vessels in patients with retinal vein occlusion.

Design: Prospective, cross-sectional study.

Methods: We performed a prospective study.

Migration of emboli in the retinal artery: case report.

Branch retinal artery occlusion (BRAO) is a prevalent vascular occlusive disorder of the eye. In transient BRAO, an embolus temporarily blocks the vessel and then moves on resulting in recovery of blood circulation. In this case, we have documented migration of the embolus with recovery of perfusion of the retina and improvement of visual acuity in a patient with transient BRAO.

The natural evolution of idiophatic epimacular membrane.

Background And Aims: Epiretinal membrane (ERM) refers to a semi-translucent tissue layer found on the inner surface of the retina especially in older people. Surgical treatment remains controversial, optimal timing for such treatment is difficult to determine and data on the natural evolution of this disorder are limited. In this study we evaluated the natural course of idiopathic epimacular membrane in 49 patients (53 eyes).
