Keratoconus: Causes, Tests, and Treatment Options

By Alan Edgar

Keratoconus is a degenerative and slow progressive disorder often presented in the teens or early twenties with steepening results: slight blurring, distortion of vision and increased sensitivity to light and glare. For ten to twenty years, it may progress and then slow or stabilize. This is may go undetected for long periods of time because there is no display of any acute symptoms such redness and inflammation. Experts believe it always affects both eyes, although you may notice more severe symptoms in only one eye. If you or a loved one is suffering from keratoconus, this informative book outlines the causes, tests and treatment options available to combat this distressing disorder.

Together with these changes, you become sensitive to glare and light affecting your ability to drive or read normal print. In addition, you seem to see halos over bright lights. These changes in your vision tend to worsen from day to day. Eventually, you’re diagnosed as suffering from a degenerative disorder of your cornea known as Keratoconus (KC).
