Purpose : Prevalence of keratoconus in the State of Qatar remains unknown. Keratoconus is reported to affect all ethnicities with a higher prevalence in Asians when compared to Caucasians. The incidence and prevalence of keratoconus have been extensively studied across the world. It is the aim of this study to calculate referred keratoconus cases to the main tertiary medical institution in Qatar.

Methods : All subjects participated in this study were referred from five different cities (Doha, Al Rayyan, Al Wakrah, Al Khor and Al Ruwais) to the Optometry department at Hamad General Hospital (HGH), Doha, Qatar. A total of 1628 records of patients diagnosed with keratoconus from 1, January 2005 to 31, December 2015 were reviewed retrospectively. Data were statistically analysed by one-way analysis of variance (one-way ANOVA) for determining the prevalence among males and females and as well as the prevalence in different regions.

Results : The cities of Al Rayyan and Doha had similar and higher percentage of referred cases of keratoconus with 37.22% and 37.04% respectively. The cities of Al Wakrah and Al khor had an intermediate level of referred cases of keratoconus at 9.40% and 10.57% respectively. Least percentage of referred cases (5.77%) came from the city of Al Ruwais. For the cities of Al Wakrah and Al Ruwais, the number of referred keratoconus patients (62.09% and 61.70% respectively) was greater in males than in females (37.91% and 38.40% respectively). The number of referred patients, males and females, with keratoconus from the two cities of Al Khor (54.07 % and 45.93 %) and Al Rayyan (50.16% and 49.84 %) did not show a significant variation.

Conclusions : Estimated number of keratoconus, as referred cases, in HGH, Doha, Qatar is 0.81 per 100,000, and the mean patient age was 21.7±7.32 (range: 14-49 years).
