Macular HoleMacular hole Surgery, what in entails.
The macula is an extremely light sensitive zone in the retina of the human eye. Macula Densa has a rich concentration of rod and cone cells so they are responsible for providing us with sharp and crisp images of our surroundings, while we read, drive and look at something closely. A hole in the macula can give rise to various complications in the vision of a human being. Macular holes usually occur in people aged above sixty and the only way to cure the problem is to perform a surgery. Macular surgery is very popular in treating the condition, which can cause a disruption in central vision of a person. Causes The interior of the eye is filled with a transparent gel like substance called the Vitreous humor. The vitreous humor constitutes of as much as about eighty percent of the eye’s mass and it helps maintain the round shape of the eye. There are a number of small fibrillar structures in the vitreous that anchor the retina to its place. As we grow old the vitreous shrinks and pull the fibers away. If the vitreous is firmly anchored to the retina then this pulling action can tear the retina and create a hole. The fluid that replaces the vitreous humor now seeps in and fills up the macula and thereby distorts the vision. Symptoms Straight lines look bent and objects in the direct line of vision start to appear blurry. Te focusing and refocusing of the eye takes a long time. Partial blindness in the affected eye is very common, unless treated with surgery. The most popular surgical procedure is known as the Vitrectomy. In this surgery the Vitreous gel is removed to stop it from pulling the retina. The vitreous humor is then replaced by a bubble containing a mixture of air and gas, this mixture helps the eyeball retain its original shape. The bubble also acts as a dressing on the hole and gives it the time to heal completely. The patient is required to lie in a face down position for two to three days so that the macula can be healed. After macular hole fills up, the air and gas is absorbed by the eye and is replaced by natural eye fluids. The most common problem of the surgical procedure is that, this increases the chances of cataract development in older patients. The patients are advised to consult their doctors and weigh out the options before going under the knife.
