Decreased Vision Due to Keratoconus
Keratoconus is a deterioration of the cornea whose cause is unknown, resulting in gradual bulging from the normal round shape to a cone shape. This condition causes decreased visual acuity. It is frequently discovered during adolescence.
Keratoconus is more common in contact lens wearers and people with nearsighted eyes. Some researchers believe that allergies may play a role.
The earliest symptom is a subtle blurring of vision that is not correctable with glasses. (Vision is generally correctable to 20/20 with gas-permeable contact lenses.)
Keratoconus can usually be diagnosed with a slit-lamp examination of the cornea along with sophisticated topographical testing that gives a contour map of the curvature of the cornea. When keratoconus is advanced, the cornea may be thinner in areas. This can be measured with a painless test called pachymetry.
In most cases, vision can be corrected with gas-permeable contact lenses. Severe cases may require corneal transplantation; results are usually good after a long recovery period. Dr. Kent Leavitt also uses Intacs using the IntraLase™ laser to form the channels.
