Diabetic retinopathy is a common eye problem among diabetic patients. It is also the leading cause of blindness of adults in the US. The condition damages the blood vessels in the retina. This light-sensitive nerve tissue transmits visual images to the brain so if it is damaged, a patient is unable to see.
How the Condition Progresses
Therefore, services in ophthalmology in Madison, AL feature surgery for this this type of vision concern. When the blood vessels weaken in the eye, they often leak fluid into the surrounding tissue. When this happens, macular edema results, which is a type of swelling. In turn, abnormal new blood vessels may grow on the retina, bleeding into the eye and blocking the ability to see.
Get Your Eyes Checked Regularly
As diabetic retinopathy progresses, the retina becomes detached from the eye, which results in permanent blindness. However, irreversible vision loss can be stopped with early detection and treatments. That is why it is important for people to have their eyes checked by an ophthalmology specialist regularly. In addition to a vision exam, the doctor will also look for indicators of the disease.
A Gradual Process
Retinal damage occurs gradually. If you have a high blood glucose count or suffer from hypertension, this type of condition can damage the tiny blood vessels in the retina. In the first stages of the condition, the blood vessels weaken and swell. They also become clogged, which affects the circulation. However, you still may not experience any vision problems during this time. That is why you need to seek out ophthalmology services even if your vision seems fine.
In the later stages of the condition, you may see floating spots or darkness. Sometimes the blood clears on its own. Still, you usually need to undergo surgery in order to remove the excess blood. Over the years, weak and swollen blood vessels can develop scar tissue and, as indicated, pull the retina away from the eye. When the retina becomes detached, patients usually see spots that float or lights that flash.
