Keratoconus is an eye condition that you may not be familiar with until you are already suffering from it. This common disorder is characterized by a structural change within the cornea which renders it unable to hold its dome-like shape. The cornea instead begins to curve forward like a cone, causing a range of vision problems.

About Keratoconus

Normally, the cornea is held together by proteins in the eye known as collagen. As the protein fibers weaken, their ability to hold the round shape of the cornea is reduced which creates the cone-like effect of keratoconus. Its exact cause is not known, but it appears to be a hereditary disorder. Although it often begins without cause or explanation, it has sometimes been linked to excessive eye rubbing due to allergies. It can begin to occur at almost any time in your life, but it becomes less likely after the age of 40.

Effects of Keratoconus

The change in shape to the cornea causes the light collected by the eye to be distorted which can lead to a variety of eyesight issues. Blurred vision, glare, halos, and light streaking are all common symptoms of keratoconus. The effects of this disorder usually develop in one eye before becoming apparent in the other. Although the gradual transformation of the cornea can persist for decades, the changes sometimes stop suddenly.
