The document contains statistics on the prevalence of keratoconus by region in Saudi Arabia, with the highest rates in the central and southern regions. It also includes data on the mean age of keratoconus patients, risk factors like consanguineous marriages, eye rubbing and UV exposure. Additional information presented includes the incidence and severity of keratoconus in Asir Province, Saudi Arabia, mean age of patients there, rates of positive family history and atopic disease. The conclusion recommends that Saudi Arabia's high prevalence may be due to genetic and environmental factors and that earlier contact lens correction and more screening could help manage the condition.
