Degeneration of the retina annulare (DRC) is an eye disease characterized by loss of peripheral vision. This is a rare disease that occurs mainly in older people.
The main cause of DRC is degeneration of the peripheral parts of the retina, which are responsible for the perception of peripheral vision. As a result of the loss of these areas, the visual image becomes distorted and unclear, which leads to limited vision.
Symptoms of DRC may include blurred vision, especially in dark or low-light conditions, limited field of vision, distorted vision, and flickering or flashing lights. In rare cases, DRC can progress and lead to complete loss of vision.
The diagnosis of DRC can be made by examining the eye and performing special vision tests such as perimetry and electroretinography. Optical coherence tomography may also be performed, which provides a more detailed image of the retina and determines the extent of its damage.
Treatment for DRC is aimed at slowing the progression of the disease and preserving remaining vision. This may include laser therapy, injections of medications such as medications for pain and inflammation, as well as vitamin complexes and other supportive therapies.
Overall, annular retinal degeneration is a serious eye condition that can lead to limited vision and a decrease in the patient's quality of life. Therefore, it is important to seek medical help at the first signs of the disease and follow your doctor’s recommendations for treatment and prevention of progression of DRC.
