Summary
Definition
History and exam
Key diagnostic factors
- positive family history
- presence of an associated syndrome
- decreased peripheral vision
- night blindness
- impaired dark adaptation
- decreased central acuity
- atrophy of retinal pigment epithelium
- bone spicule pigmentation
Other diagnostic factors
- waxy pale optic nerve
- photopsias
- refractive error
- cataracts
- retinal vascular attenuation
- cystoid macular edema
- vitreous cells
- glare from bright lights
- abnormal color vision
- keratoconus
- glaucoma
- optic nerve head drusen
- Coats-like retinopathy
- Leber congenital amaurosis
Risk factors
- family history
- presence of an associated syndrome
Diagnostic investigations
1st investigations to order
