What is a retinal vein occlusion?
<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t

A retinal vein occlusion occurs when one of the veins responsible for draining blood from the retina becomes blocked.
This blockage causes increased pressure inside the affected vessels, leading to retinal hemorrhages, reduced blood flow, and leakage of fluid into the retina.


<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tThe retina is the light-sensitive layer at the back of the eye that converts light into visual signals. When its blood circulation is affected, vision may become blurred or reduced.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tRetinal vein occlusion is one of the most common retinal vascular diseases, especially in older adults. \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Types of Retinal Vein Occlusion
\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tThere are two main forms:
\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t

1. Central Retinal Vein Occlusion (CRVO)
<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tThe main retinal vein becomes blocked at the level of the optic nerve.

Because a larger part of the retina is affected, symptoms may be more severe.
\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t

2. Branch Retinal Vein Occlusion (BRVO)
<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tSmaller, peripheral veins of the retina become blocked.
The damage is more localized, but it still requires close monitoring.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tIf it occurs in one eye, there is about a 10% chance that it will also occur in the other eye in the future.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
