Keratoconus does not make people go blind. However the changes to the cornea can make it impossible for the eye to focus without eyeglasess or contact lenses. Keratoconus can be dangerous if laser vision correction surgery (LASIK or PRK) is performed on the eye.
Cause. Keratosis pilaris is caused by a buildup of keratin, the protein that protects skin from infections and other harmful things. The buildup forms a plug that blocks the opening of a hair follicle, but doctors don't know what triggers the buildup. If you have dry skin, you're more likely to have keratosis pilaris.It's usually worse in the winter months, when there's less moisture in the air, and then may clear up in the summer. It often affects people with certain skin conditions, including eczema (also called atopic dermatitis).f you have dry skin, you're more likely to have keratosis pilaris.
