Keratoconus

Keratoconus is progressive bilateral ectasia of the cornea into a conical shape, presenting in adolescence/adulthood with progressive myopia and irregular astigmatism. It may be associated with atopy/eye rubbing. Clinical: irregular astigmatism, Munson sign, apical scarring. Treatment: rigid gas-permeable contact lenses for vision; corneal collagen cross-linking to halt progression; corneal transplantation for advanced/scarred cases.

Common Symptoms

Progressive myopia/irregular astigmatism; conical cornea; Munson sign; atopy/eye-rubbing history

Causes and Pathogenesis

Corneal stromal weakening thins and bulges into a cone, causing irregular astigmatism.

Treatment

RGP contact lenses; corneal cross-linking to halt progression; transplant for advanced

Preventive Measures

Avoid eye rubbing; early cross-linking.
