Case of the week: Keratoconus
Keratoconus is a progressive ocular condition in which the cornea bulges forward forming a cone like shape. Approximately 1 in every 1500 people have keratoconus. The exact cause is unknown but there does seem to be a genetic component. Also, extensive eye rubbing has been shown to increase the risk/progression.
The best treatment for keratoconus is early detection and corneal cross-linking. I have posted a picture of an eye undergoing the cross-linking procedure. Cross-linking involves putting riboflavin drops into the eye and then using UV light to strengthen the corneal integrity and prevent further cone formation. Visually, special contact lenses called scleral lenses usually provide the best vision for these patients.
