Keratoconus: Symptoms & Signs

Keratoconus describes the condition in which the cornea of the eye takes on an abnormal shape and bulges outward in a cone shape due to pressure within the eye. Conical cornea is another name for the condition. It usually begins in the teen years, and the shape changes in the cornea take place over many years.

Signs and symptoms associated with keratoconus include double vision when looking with one eye, the appearance of halos around bright lights, sudden vision change in one eye, and distorted or blurred vision (depending on the stage of the disease). Other associated changes with keratoconus include the development of nearsightedness and astigmatism as the cornea changes shape.
