Causes of Retinitis Pigmentosa

Genetic changes in cells of the retina are the primary cause of Retinitis Pigmentosa (RP). RP is a genetic disease that is present from birth and is usually inherited in different ways. It can also be associated with other genetic conditions, like Usher syndrome. While RP can be caused by certain medicines, infections, or eye injuries, these causes are less common.

The progression of RP varies among individuals, with symptoms usually starting in childhood. Early symptoms include loss of night vision and loss of side (peripheral) vision. As the disease progresses, the field of vision narrows, leading to tunnel vision. Other symptoms include sensitivity to bright light and loss of color vision.

Research is ongoing to develop potential treatments for RP. Clinical trials and experimental therapies may be available for some patients. Although there is currently no cure for RP, vision aids and rehabilitation programs can help manage the condition and improve quality of life. It is important to work with a healthcare team to develop an individualized treatment plan and to have regular eye exams to monitor symptoms and detect other eye problems associated with RP.

Diagnosis of Retinitis Pigmentosa

To diagnose Retinitis Pigmentosa, your eye doctor will perform a comprehensive dilated eye exam. This exam allows the doctor to examine the retina and look for signs of RP, such as the presence of pigment deposits or changes in the blood vessels. In addition to the dilated eye exam, your doctor may also conduct several diagnostic tests to further evaluate your condition. These tests may include:

1. Visual field test: This test measures your peripheral vision and can help determine the extent of vision loss caused by RP.
2. Electroretinography (ERG): This test measures the electrical response of your retina to light stimulation, providing valuable information about the function of your retinal cells.
3. Genetic testing: This test can identify specific genetic mutations associated with RP and help determine the inheritance pattern of the disease.

In some cases, your doctor may also recommend genetic counseling to discuss the implications of the test results. While there is currently no cure for RP, there are visual aids and rehabilitation programs available to help manage the condition. Additionally, ongoing clinical trials and research on gene therapy offer hope for future treatments.

Treatment of Retinitis Pigmentosa

If you have been diagnosed with Retinitis Pigmentosa, your treatment options will primarily focus on managing the symptoms and improving your quality of life.
