Superior temporal venous branch occlusion

Color retinography showing secondary ORVTS with intraretinal hemorrhages and hard exudates in said territory

Description

Retinal vein occlusion (RVO) is the second most common cause of vision loss due to retinal vascular disease, after diabetic retinopathy. Branch vein obstruction (BRVO) is more common than central retinal vein obstruction (CRVO). BRVO can be major or primary, affecting a first-order branch, macular, or minor, affecting only one macular branch, or secondary, affecting a branch without macular involvement, and is generally asymptomatic. High blood pressure (HBP) and diabetes are the risk factors most frequently associated with the appearance of vascular occlusion in patients over 60 years of age. In patients younger than this age, however, it is necessary to rule out other causes of hypercoagulability (entities related to blood hyperviscosity, thrombophilia, etc.).

Indication

A 48-year-old woman with a history of type 2 diabetes mellitus and poorly controlled hypertension came to the emergency room with a hypertensive emergency. During admission, an ophthalmology consultation was requested to assess the fundus, where the presence of a secondary ORVTS in the right eye was observed with intraretinal hemorrhages in said area, without macular edema. Visual acuity was one unit, and the angiography ruled out the presence of retinal ischemia.
