Retinitis Pigmentosa is a disorder of the eye that affects the ability of the retina to respond to light. This genetic disorder causes the slow loss of vision. The initial sign of this disorder is a loss or reduction in night vision followed by the loss of peripheral vision.
HOW IS RETINITIS PIGMENTOSA DIAGNOSED?
Tests to evaluate the retina include:
• 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?
Currently there is no known cure for retinitis pigmentosa. Research has shown that vitamin A palmitate may slow the progression of certain forms of RP. Another way to slow the vision loss from RP is to wear sunglasses to protect the retina from harmful ultraviolet (UV) light.As RP is a genetically-based disease, gene therapy has become a widely explored area of research, particularly in identifying ways to insert healthy genes into the retina.
DID YOU KNOW?
Complete blindness to occur in patients with retinitis pigmentosa is extremely rare.
