Eye vascular problem

Eye vascular |
The retina is behind the eyes. The most common of these retinal vascular problems is blockage after diabetes. Blood vessel blockage can occur in both veins and arteries. It can again block the main vein or artery of the retina i.e. Or a branch (capillary or venule) may be blocked. We are more or less familiar with the blockage of blood vessels in the heart. Retinal blood vessel blockage is also in the same process.
A clot is called a thrombus. The solid lipid or cholesterol is called embolus. When either a thrombus or an embolus blocks a vein or artery, the blood supply to that area is blocked and the oxygen supply is cut off. This is called a stroke. Strokes can occur in the retina as well as in the brain. Nerve cells or neurons need an uninterrupted supply of oxygen to survive. Nerve cells or neurons are damaged due to temporary interruption of blood or oxygen supply. Once any nerve in the body is damaged, it is permanently damaged.
There are two types of blood vessel blockage or stroke in the retina:
1. Vein block or arterial occlusion can be central retinal artery or any of its branch blocks.
2. Arterial block or venous occlusion-central retinal vein block or any of its branch blocks.
Causes of retinal vascular blockage:
The main causes of venous blockage are blood clots (thrombus) and clotted lipids and cholesterol embolus. The main sources of these thrombus and embolus are the heart valves and atherosclerosis or fat deposits in the veins.
Venous atherosclerosis is the leading cause of arterial occlusion. Atherosclerosis causes the veins to thicken and harden, and the arteries become blocked by direct pressure.
Among the many risks of vascular occlusion are atherosclerosis, aging, hypertension, hyperlipidemia or high cholesterol, diabetes, smoking, taking birth control pills, glaucoma, blood problems such as thalassemia or sickle cell anemia. This problem can also occur with the side effects of radiotherapy.
Symptoms and do's and don'ts
When the blood vessels of the retina are blocked, vision suddenly becomes blurred in one eye. It is more common in adults. There is no pain. eye angiogram is performed to identify retinal vascular block.
If not treated quickly, there is a risk of permanent loss of vision. Awareness is needed to prevent such problems. Diabetes, high blood pressure, hyper cholesterol lemia etc. should be controlled. Anti-VGF injections may be given to the eyes. There are many benefits to laser treatment. Aspirin-type medications may be needed.
