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.
Medics at Ruhr-Universitaet-Bochum in Germany have found the cause of a hereditary, progressive form of blindness: they have identified the previously unknown protein CCDC66, the loss of which initially leads to night blindness and in due course usually results in complete blindness.
