Macular Degeneration is considered as the most prominent cause of losing oneâs vision. It is affecting more people compared to the combined percentage of glaucoma and cataract. Currently, it is known to be incurable since it is not like other eye disorders where the problem can be corrected via lasik eye surgery or correction glasses. However, there are treatments available that can help in delaying the progress of the condition or even in improving the vision of the patient.
This condition becomes present on one or both eyes when the deterioration of the retinaâs central portion started. The retina can be found at the eyesâ inside back layer and is the one recording all images you see and sending these images through the optic nerve from your eyes directly to the brain. The central portion of the retina is called the macula and is responsible for keeping the central vision of the eye. It is the one controlling the ability of a person to drive, read, recognize colors and face and see objects with fine detail.
When the maculaâs condition is affected, the ability of performing various visual tasks and seeing each in fine detail will be affected.
Different Forms of the Eye Disease
There are different forms of this eye disease that you can be diagnosed with. Your diagnosis can either be wet which is also called neovascular or dry which is non neovascular. The term neovascular pertains to the growth or production of new blood vessels within inappropriate areas like the macula. It affects the central vision that causes blind spots for the person suffering from the disease.
Wet or Neovascular Form
It is the form where the new blood vessels are growing just beneath the retina and leaking fluid and blood. The leakage is the one causing permanent damage to the retinal cells that are light-sensitive that eventually die off and result in blind spots in the central vision.
CNV or Choroidal Neovascularization is the basic process that causes this wet form of the eye disease. It is the misguided way of the body in attempting to make a new structure of blood vessels for supplying the retina with more oxygen and nutrients. Instead of helping, it only creates scarring that leads to the severe loss of the central vision.
Dry or Non-Neovascular Form
Unlike the wet form, this one is considered as its early stage and is basically associated with thinning and aging of the macular tissues. It can also be due to the deposit of pigments within the macular or can be the combination of the two causes. This form of the eye disease is usually diagnosed when there are yellowish spots called drusen start accumulating in and around the eyeâs macula. Experts believe that these are debris or deposits coming from the deteriorating tissue. With this form, the loss of central vision may progress gradually but the symptoms are not as serious as the wet one. However, the slow progress over the years may lead to geographic atrophy that is known as the gradual degradation of the retinal cells that can also lead to severe loss of vision.
