Brief summary
Purpose: To search platelet activation via detecting three important platelet activation parameters; Mean Platelet Volume (MPV), Platelet Distribution Width (PDW), and Plateletcrit (PCT) in patients with branch retinal vein occlusion (BRVO) in comparison to those in healthy adults as controls. Design: A prospective case control study Participants and Controls: 30 patients within the BRVO (Group 1) and 30 age-and sex-matched healthy controls will included into the study (Group 2). Methods: All patients and control subjects will undergo complete ophthalmologic evaluation. MPV, PDW, and PCT were measured in the studied groups. Main Outcome Measures: Alterations in platelet activation parameters. The mean level of MPV PDW and PCT value in Group 1 and in Group 2 will determined.
Interventions
Blood sampled will be collected in patients with acute branch retinal vein occlusion (BRVO). Platellet activation will be assessed. Patients with BRVO will be treated with conventional therapy. Duration of observation is 1 month.
