Analysis of optic disc damage by optical coherence tomography in terms of therapy in non-arteritic anterior ischemic optic neuropathy.

This study aimed to assess the relationship between the rate of nerve fiber loss in non-arteritic anterior ischemic optic neuropathy (NAION) and time delay before therapy. Total 24 patients received the same treatment within or after 2wk (early and late groups). There were significantly lower level of destruction of nerve fibers (P=0.

Increased level of platelet P-selectin in nonarteritic anterior ischemic optic neuropathy.

Purpose: P-selectin receptor is expressed in platelets and endothelial cells in a cell-activation-dependent manner. Platelet P-selectin (CD62) levels may become elevated in a number of vasoocclusive diseases, including arteriosclerosis, atherothrombosis, and diabetes mellitus (DM). Nonarteritic anterior ischemic optic neuropathy (NAION) is associated with a sudden loss of vision due to the vascular insufficiency of ciliary arteries supplying the optic nerve.

Bilateral central retinal vein occlusion caused by malignant hypertension in a young patient.

Central retinal vein occlusion (CRVO) occurring simultaneously in both eyes is a rare condition, in such cases usually associated with severe systemic disease. Overall, only 10% of all CRVO patients are younger than 40 years. A relatively young patient reported with simultaneous bilateral CRVO associated with chronic kidney disease and malignant hypertension.
