Artery Blockage and Retina Vein Center



- Retinal Disorders, Eye Disease
The central retinal artery, the main channel that supplies blood to the retina, can become completely blocked by atherosclerosis or particles, such as blood clots, which enter the bloodstream and block the duct (embolism). Inflammation of the blood vessels is also likely to cause retinal artery insulation. In people with glaucoma, diabetes, or high blood pressure, various processes may occur, which can lead to venous isolation.

If the retinal central artery is clogged, the affected eye experiences a sudden but painless loss of vision. The presence of a central retinal vein causes the full vein to expand in front of the optic nerve. Loss of visibility from mild to severe because the central retinal artery is insulated. Recurrence is common.

In addition to losing a severe outlook, complications from the encapsulated central retinal artery or vein include bleeding into the eye and glaucoma caused by abnormal blood vessel growth in the rainbow film and angle, where fluid is drained from the eye.

DIAGNOSIS

Using ophthalmoscope, a physician may see changes in the blood vessels and other signs of reduced blood supply to the retina, such as the retinal pallor in the terse arterial case or full vein and swelling in front of the optic nerve in the case of a sealed vein. Fluorescein angiography action in which a doctor injects a dye into the veins and then photographing the retina helps determine the least amount of damage to the retina and helps the doctor's treatment plan. Doppler ultrasound scans may sometimes be used to check blood flow in the bloodstream.

TREATMENT

Treatment as soon as is often given in an attempt to remove retinal artery blockage. However, treatment is rarely effective. Pressure in the eye can be reduced by massaging the eyelids closed intermittently with the fingers. Alternatively, a procedure called anterior chamber paracentesis may help to reduce pressure inside the eye. In this procedure, eye drops are applied to the eye to numb the eye, then the needle is inserted into the anterior chamber of the eye to suck a little liquid, thus rapidly reducing the pressure in the eye. Reduced pressure inside the eye with a massage or anterior chamber paracentesis may excrete blood clots or other plugs and may enter smaller chambers, thereby reducing the damage area of ​​the retina. Generally no approved drug therapy. Laser treatment may be used to destroy abnormal blood vessels if they progress to a rainbow or angle film
