A Retrospective Study Of Pre And Post Treatment OCT( Optical Coherence Tomography)In Patients Of BRVO (Branch Retinal Vein Occlusion)With Macular Edematreated With Intravitreal Injection Bevacizumab(1.25mg/0.05ml) Attending Ophthalmology Department Of Ter

ABSTRACT

Background:Retinal vein occlusion (RVO) is the second most common sight threatening retinal vascular disorder after diabetic retinopathy. Retinal vein occlusion is a common form of retinal vascular disease, especially in middle-aged and older individuals. Occlusion results due to thrombotic effect on the retinal vein . BRVO is classified according to the anatomical location as major or macular. Major BRVO refers to occlusion of a retinal vein that drains one of the quadrants. Macular BRVO refers to occlusion of a venule within the macula. BRVO is further classified into perfused (non-ischemic) or non-perfused (ischemic). Ischemic BRVO is defined as > 5 disc diameters of nonperfusion on fluorescein angiography (FA).Objectives:To study pre and post treatment (Intravitreal Bevacizumab 1.25mg/0.05ml)OCTin patients with macular edema secondary to BRVO. Material And Methods:30 Eyes of 30 patients of BRVO with macular edema were studied retrospectively who attended eye opd during Sept-2012 to Aug-2014 according inclusion and exclusion criteria Afterroutine ophthalmic examination with slitlamp biomicroscopy and dilated fundus examination with indirect ophthalmoscope and preop OCT done for CFT(central foveal thickness)patient underwent intravitreal injection anti VEGF.Posttreatment OCTof these patients were reviewed after 1 week and 1 month retrospectively.Result:Significant improvements in CFT were observed in these patients after treatment. Results were analyzed based on the duration Of the treatment given, after 1 week and after 1 month.Conclusion:Early diagnosis & treatment of the pathology contributes to the better visual outcome.
