What is cystoid macular edema?
Cystoid macular edema is an eye failure in which small pockets or cysts accumulate in the center of the retina. In most cases, the accumulation of fluids is the result of broken or escaping blood vessels in the eye. Cataract surgery is the main cause of cystoid macular edema due to accidental damage to the retinal blood vessel. Many other conditions, including trauma, diabetes and viral infections, can also be preceded. Blurred vision and other symptoms usually disappear within a few weeks, but the persistent cases may be treated with eye drops or occasionally surgery.
Makula is a small place in the middle of a retina that focuses on a central vision. Around the macula are hundreds of small blood vessels, which, if damaged, can escape the liquid and form yellow cysts. The condition is usually painless, although central vision can be significantly disrupted. A person may have trouble focusing on objects or text directly in front of them. Peripheral vision is typincal remained intact.
Surgical procedures to reconnect the injured retina or clean cataracts can result in a cystoid macular edema. After a delicate surgery, the immune system instinctively causes a slight chemical reaction to help the eyes to heal. The resulting inflammation can damage the blood vessels and possibly cause them to break. Most cases of post-surgical cystoid macular edema themselves without treatment in two to three weeks when their eyes continue to recover.
A person can also develop a cystoid macular edema after injury or eye infection. Diabetes is also a remarkable risk factor because it is known that the disease disrupts the blood vessels of the retina. In addition, some prescription drugs, including glaucoma drugs and certain cancer types, can also cause cystoid macular edema.
The eye physician can usually diagnose the condition during the routine eye test. If it is not clear whether swelling and more are presentCyst, an X -ray procedure called fluorescein angiogram can be performed. A fluorescent dye is injected into the bloodstream, which is distributed in the eyes through the blood vessels. X -ray images can monitor the movement of the dye to see if the blood vessels are escaping into the macula.
The treatment of the persistent cystoid macular edema depends on the basic cause. When infections and diabetes are adequately treated, symptoms usually clarify rapidly. Medicated eye drops or injected solutions may be administered to relieve inflammation and reduce the healing time. If other treatment fails, surgery can be considered for cauterizing blood vessels and removal of damaged tissue.
