OBJECTIVE To determine the relative position of the two vessels at the site of venous obstruction, as it facilitates Arteriovenous adventitial sheathotomy and to look for the associated diseases with branch retinal vein occlusion (BRVO) so as to create more awareness among the masses. METHODS It was a case series carried out at the Ophthalmology out-patient department of Ziauddin University H...

cystoid macular edema is a condition that involves the macula, caused by an accumulation of extracellular fluid in the macular region with secondary formation of multiple cystic spaces. this condition is provoked by a variety of pathological conditions such as intraocular inflammation, central or branch retinal vein occlusion, diabetic retinopathy and most commonly following cataract extraction...

tinct zones, each with different venous drainage. Between these 2 zones, a watershed developed. After the 2 chorioretinal anastomoses matured, blood flow through the venous tributary that bridged the watershed zone— the tributary connecting the inferotemporal branch retinal vein to the central retinal vein—was very slow (Figure 2B). The slow blood flow made that blood vessel susceptible to veno...

Venous thrombosis is associated with Virchow’s triad. This involves the combination of hypercoagulability, damage to the vessel endothelium and haemodynamic changes in the form of stasis or turbulence. These features ultimately contribute to thrombosis formation (Heit 2008). Venous thrombosis can affect the eyes, resulting in serious ocular symptoms and is a significant cause of vision loss wor...
