Keratoconus comes in a variety of forms. Depending on your symptoms, you may be experiencing one of the following forms of this disease:
- Forme fruste Keratoconus is a mild form and a precursor of the disease. It is a mild form of the condition that usually causes few issues.
- Nipple cone Keratoconus involves the cornea forming a cone-like shape. Common symptoms include blurry and distorted vision.
- Oval cone Keratoconus is a version where the cornea bulges into an oval shape. The bulging tends to occur at the bottom outer part of the cornea and can make it look as if it is sagging.
- Pellucid Keratoconus is a version of KC with inferior thinning of the cornea from the outside in.
- Globus cone Keratoconus is the most severe form of the disease. It causes an individual’s cornea to thin and bulge into a round shape.
