Awareness and Knowledge About Glaucoma in the Western Region of Saudi Arabia: A Population-Based Survey.

Background Glaucoma is a leading cause of irreversible blindness worldwide. This study aimed to assess the Saudi population's levels of awareness and knowledge regarding glaucoma risk factors, symptoms, treatment, and outcomes. Methods A cross-sectional study was conducted among the Glaucoma Awareness Campaign attendees during the World Glaucoma Week (2015-2016). A structured questionnaire was used, and a knowledge score (0-25) was calculated as the sum of all correct answers. Sociodemographic factors, personal and family history of glaucoma, and the presence of risk factors were investigated and analyzed as factors affecting knowledge. Results The study included 1751 participants, with a mean age of 40.23 (SD ±13.86) years; 51.5% were males, 3.7% had glaucoma and 22.6% had a family history of glaucoma. The overall awareness rate was 65.6%, which was moderately higher among females (71.6%), older participants (≥40 years, 69.7%), and highly educated participants (70.6%). Concerning knowledge, 15.4% had fair to good knowledge (score 15-25). Participants with a personal history of glaucoma had relatively greater knowledge regarding glaucoma-specific questions, such as optic nerve damage (p=0.001) and the requirement of lifetime treatment (p<0.001). Conclusion Awareness and knowledge about glaucoma are limited among the Saudi population, regardless of socioeconomic class or educational status. Knowledge about glaucoma should be further promoted to enable early screening and prevention.
