RETINAL THROMBOSIS Meaning and
Definition
-
Retinal thrombosis refers to the formation of a blood clot (thrombus) within the blood vessels of the retina, a thin layer of tissue located at the back of the eye responsible for transmitting visual information to the brain. The condition occurs when there is an obstruction or blockage in the retinal blood vessels, leading to limited blood flow and subsequent damage to the affected area.
The symptoms of retinal thrombosis can vary depending on the location and severity of the clot, but they typically include sudden, painless vision loss or blurry vision in one eye. In some cases, the whole field of vision may be affected, leading to partial or complete blindness. The condition can be categorized into central retinal artery occlusion (CRAO), when the main artery supplying the retina is blocked, or branch retinal artery occlusion (BRAO), when one of the smaller branches of the artery is affected.
Retinal thrombosis can be caused by various factors, including underlying medical conditions such as hypertension, diabetes, hyperlipidemia, or clotting disorders. Other risk factors include smoking, aging, cardiovascular disease, and certain medications.
Immediate medical attention is crucial when retinal thrombosis is suspected, as early intervention can help prevent further damage and potentially restore or improve vision. Treatment options may include medications to dissolve the clot, increased blood flow to the area, or surgery in severe cases. Regular monitoring and management of underlying risk factors are also essential to prevent recurrence and minimize the risk of complications.

Etymology of RETINAL THROMBOSIS
The word "retinal" refers to the retina, which is the light-sensitive layer at the back of the eye responsible for receiving and transmitting visual information. The term "thrombosis" comes from the Greek word "thrombos", meaning "clot" or "lump".
"Retinal thrombosis" is a medical term used to describe the formation of a blood clot in the blood vessels of the retina, leading to the blockage of blood flow. The etymology of the term essentially combines the specific anatomical location (retina) and the pathological process (thrombosis) occurring within it.
