Optometrist Questions Keratoconus

What causes keratoconus?

My husband has been diagnosed with keratoconus in both his eyes. What could have caused this and what will be the course of treatment? I am unfamiliar with this condition. Did it come from his astigmatism?

Keratoconus is a degenerative thinning of the cornea, frequently associated with eye rubbing. There is some genetic component as well. Changes in prescription and frequent increases/shifts in astigmatism occur. Chances are, if your husband was recently diagnosed, he is not likely to develop severe stages. Most commonly, the condition is found in teenage years due to significant prescription shifts and decreased vision. Most commonly, the condition is managed with glasses and contact lenses. Corneal crosslinking is another commonly used to stabilize the cornea. The best thing is to get eye exams yearly or sooner when a vision change is noticed. This is a medical condition, so your medical insurance should be used for the exams.
It runs in families. Thinking of the cornea. Call a corneal specialist to do a collagen interlace treatment to stop the progression of the condition. Must use RGP lenses for better vision.

Keratoconus is a hereditary condition. It usually occur in young males in their late 20's. Keratoconus is like having a "cone shaped" cornea instead of a "doom shape" cornea and that is why he has high astigmatism. Current treatments are available in the US, with corneal cross linking. This procedure used Riboflavin and UV light to harden the corneal, therefore strengthen it and reduce astigmatism. This treatment is not corrective, but used to reduce the amount of astigmatism and prevents corneal ruptures.

Keratoconus means cone-shaped cornea. It is a condition that involves genetics, and mostly guys are affected at puberty. A lot of times, constant rubbing of the eyes aggravates the condition. Treatment includes glasses, hard contact lenses, and cross linking surgery.
