Abstract: Retinal vein occlusion remains the second most common cause of vision loss from retinal vascular disease, second to diabetic retinopathy. Retinal vein occlusions (RVO) are categorized into branch (BRVO), hemiretinal (HRVO) or central retinal vein occlusion (CRVO) depending on the location of the occlusion. Vision loss from retinal vein occlusions is secondary to macular edema. Macular oedema (ME) occurs in a wide variety of pathological conditions and accounts for different degrees of vision loss. Early detection of ME is therefore critical for diagnosis and therapeutic management. Optical coherence tomography (OCT) is a non-contact, diagnostic method that uses infrared light, which allows the analysis of the retinal structure by means of high-resolution tomographic cross sections............
