Retinal Vein Occlusion
Retinal vein occlusion, also known as RVO, is a common eye condition that occurs when there is a blockage in one of the veins that carry blood away from the retina. This blockage can cause blood to build up in the retina, leading to potentially significant visual impairment. There are two types of RVO: branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO). BRVO occurs when a smaller vein in the retina becomes blocked, while CRVO happens when the largest vein in the retina is affected. Risk factors for RVO can include high blood pressure, diabetes, high cholesterol, smoking, and certain blood disorders. Symptoms of RVO may include blurry or distorted vision, a loss of vision in an eye, eye pain, and the appearance of floaters. While treatment for RVO depends on the severity of the condition, options may include medications to manage symptoms, laser therapy to reduce swelling, or surgery to prevent further vision loss. It is important to seek medical attention promptly if you experience any changes in your vision, as timely treatment can help prevent long-term vision impairment. Regular eye exams can also help detect and manage conditions like RVO, and may help prevent future complications.
