- Color vision;
- Exam of the retina by ophthalmoscopy after the pupils have been dilated;
- Fluorescein angiography;
- Intraocular pressure;
- Measurement of the electrical activity in the retina (electroretinogram);
- Pupil reflex response;
- Refraction test;
- Retinal photography;
- Side vision test (visual field test);
- Slit lamp examination;
- Visual acuity.
How is retinitis pigmentosa treated?
There is no proven effective therapy for retinitis pigmentosa. Some studies suggest that treatment with antioxidants (such as high doses of vitamin A palmitate) may slow the disease. However, taking high doses of vitamin A can cause serious liver problems. The benefit of treatment has to be weighed against risks to the liver.
Aids including magnifying glasses and infrared night vision scopes can help people with night blindness and tunnel vision. Wearing sunglasses can protect the retina from ultraviolet light and may help preserve some vision.
