What is a macular hole?
macular hole is usually defined as a break or a small hole in the macula eyeball. The macula is a pigmented place in the center of the retina responsible for providing a sharp acute central vision. The place and size of the macular hole on the retina generally determine the severity of the visual deficit. If it is not treated, this condition may turn into a separate retina. Separate retina often threatens the view and is usually considered to be medical emergency. Symptoms may include distorted and blurred central vision. In the early stages of macular holes, patients often often experience only slight blur or distortion in their central vision. The straight lines can capture a bent or corrugated look. Fulfilling routine tasks and reading often becomes difficult. If a macular hole is present in one eye, there is often a chance of 10 to 15 percent that another macular hole in the other eye will be introduced throughout their lives. Macular holes usually begin gradually and the patient often does not know about the condition.
Sometimes macular holes can be sealed, but surgery may be necessary in many cases to improve vision. Surgery is called showcase. The display case is the removal of the eye enamel gel to prevent it from pulling it on the retina and replacing it with a combination of gas and air. This combination of gas and air forms a bubble that acts as a bandage to maintain the edges of the macular holes in place while healing. Surgery of macular holes is usually performed in an outpatient environment with a local anesthetic.
After surgery, patients usually have to keep their face for one or two days. This case may have to maintain this position for two to three weeks. The position of face down helps the bubble to put pressure on the macula, allowing it to be reabsorbed back into the eye. This usually seals the hole and allows the cavity to replenish eye fluids.
The risk of showcases involves the formation ofataracts, infections or separate retina. Patients are usually recommended not to travel on the plane, as the air pressure fluctuations can cause the air bubble to expand, increasing intraocular pressure. Visual improvement after surgery differs from man to person. Individuals who had a macular hole for six months or less usually have a more favorable chance of recovering lost vision.
