ABSTRACT
Aim : To study the spectral domain optical coherence tomography (sd-oct) characteristics of macular edema in branch retinal vein occlusion. Methods : 39 patients with branch retinal vein occlusion were studied with sd-oct . Characteristics analyzed were - integrity of inner segment outer segment junction, integrity of external limiting membrane, central retinal thickness and presence or absence of serous macular detachment. Results : 30 patients had disrupted photoreceptor Inner Segment-Outer Segment integrity. ( 76.9 %). External Limiting Membrane was disrupted in 64.2 % patients ( n=25 ). Serous macular detachment was present in 20. 5% patients. Average central retinal thickness was 363.84 microns. Conclusions : Spectral domain oct characteristics can help to predict the visual outcome in patients with macular edema due to branch retinal vein occlusion.
