Symptoms often first appear in childhood, but severe vision problems do not usually develop until early adulthood.

• Decreased vision at night or in low light
• Loss of side (peripheral) vision, causing "tunnel vision"
• Loss of central vision (in advanced cases)

Tests to evaluate the retina:

• Color vision
• Examination 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
