title: Genetics in keratoconus: A, B, O blood groups.
abstract: A, B, O blood group frequencies and Rh factors were studied in 69 white keratoconus patients and compared with 1,465 healthy white individuals. We did not detect a significant excess of any particular blood group among keratoconus patients. It was concluded that blood groups were not associated with keratoconus.
