Branch retinal vein occlusion (BRVO) associated with ocular tuberculosis (TB) is a rare presentation of retinal vasculitis but it can also present in the absence of active uveitis. [ncbi.nlm.nih.gov]

BRVO may present initially as the ischemic type, or it may progress from nonischemic. [decisionmakerplus.net]

  Common symptoms include blurred vision or changes in a portion of the visual field (peripheral vision). [vrssurgery.com]

  Patients typically complain of a sudden onset of blurred vision or defect in their central field of vision. [ellsretina.com]

  BRVO causes a painless decrease in vision, resulting in misty or distorted vision. If the veins cover a large area, new abnormal vessels may grow on the retinal surface, which can bleed into the eye and cause blurred vision. [bostonlaser.com]

• Rubeosis Iridis

  Neovascularization (abnormal new vessel formation) of the retina or iris (rubeosis iridis) occurs in about 16% of patients with central retinal vein occlusion and can result in secondary (neovascular) glaucoma, which can occur weeks to months after occlusion [msdmanuals.com]

  Late, in neglected cases, rubeosis iridis can cause secondary glaucoma and, if inadequately treated, lead to a blind, painful eye. [healio.com]

  If vessel growth on the iris occurs (rubeosis iridis), these eyes may develop a very high pressure known as neovascular glaucoma due to obstruction of the fluid outflow channels. [williamsoneyeinstitute.com]

• Confusion

  Background Much confusion exists in the literature because central retinal vein occlusions and branch retinal vein occlusions (BRVOs) are often grouped and studied together. The natural history and the complication rate for each entity differ. [emedicine.medscape.com]

The prognosis of patients with BRVO and SRD requires further investigation. [ncbi.nlm.nih.gov]

However, frequently recurring ME might result in a poor final visual prognosis in eyes treated with STTA and switch therapy ( Fig. 2B ). [nature.com]

A multi-center study, the Branch Vein Occlusion Study, found that laser improved the visual prognosis after three years of follow-up. [vrssurgery.com]

We reviewed cases in literature and combined possible etiologies. We report a previously unpublished case of retinal artery occlusion following the use of intravitreal bevacizumab. [ncbi.nlm.nih.gov]

Minocycline is a drug that might help prevent cells involved in inflammation from becoming activated. It is approved for use as an antibiotic, but it has not yet been tested to see if it can treat BRVO. [clinicaltrials.gov]

This prevents fluid from traveling through the tear and under the retina, which usually prevents the retina from detaching. These treatments cause little or no discomfort and may be performed in your ophthalmologist’s office. [hawaiivisionspecialists.com]

Progression to an ischemic status may possibly be prevented with successful anastomosis formation. Marked visual improvement may occur. [ncbi.nlm.nih.gov]

Several treatments are available to deal with the macular oedema and prevent neovascularisation (new blood vessels forming). [gladesvilleeye.com.au]

This prevents the veins from carrying blood away from the retina. [calgaryretina.ca]
