Symptoms and Treatments of Retinal Vein Occlusion

Retina Associates

At Retina Associates in Tucson, Arizona, Dr. Cameron Javid and his team offer treatment for a broad range of retinal conditions and injuries. Retina Associates welcomes patients with central or branch retinal vein occlusion.

Retinal vein occlusion occurs when a blockage develops in the main branch of the retina or in one of its secondary vessels. Both central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO) causes blood and fluid to leak into the retina. This, in turn, can cause the central area of the retina to swell and cause a blurring or loss of vision.
Vision loss due to retinal vein occlusion can affect all or part of the eye's field of vision. Onset may be sudden or gradual over the course of a few days and may even feature complete instantaneous vision loss, depending on the type of blockage. Some patients may experience dark spots or lines in the field of vision, known as floaters, that occur when clumps of leaked blood enter the gel-like substance that fills the eyeball.
There is no cure for retinal vein occlusion, nor is there a way to undo the blockage. Some patients experience restored vision without treatment.
Others require intervention to address secondary effects, such as the development of abnormal blood vessels or swelling of the central retina called the macula. Untreated, this new growth of blood vessels can lead to a special type of glaucoma and further impact vision in the affected eye.
