What symptom is commonly seen in cases of retinal vein occlusion?

In cases of retinal vein occlusion, sudden loss of vision is a hallmark symptom. This condition occurs when a vein in the retina becomes blocked, often leading to a rapid onset of visual disturbances. The blockage can cause fluid to leak from the retina, leading to swelling in the macula, which is the center of the retina responsible for sharp central vision. As a result, patients may experience a sudden decrease in vision in one eye, which can be alarming and requires immediate assessment by a healthcare professional.

Other symptoms, such as severe eye pain, bright flashes of light, and floaters, may occur with different ocular conditions but are not as directly associated with retinal vein occlusion itself. Sudden vision loss is unmistakable and serves as a critical indicator for diagnosis and urgent treatment, underscoring its significance as a symptom in this context.
