Abstract
Background Diabetes mellitus is a major public health problem worldwide. Diabetic patients may suffer many complications including diabetic retinopathy, which can lead to blindness if left undiagnosed and untreated. Methodology A cross-sectional analytical study was conducted among a sample of 251 adult diabetic patients in the Al Qunfudah district. A self-administrated questionnaire was used for data collection and consisted of the following three sections: sociodemographic data, diabetes mellitus, and diabetic retinopathy-related data.Results Out of the 251 participants, 68.5% recognized that diabetes mellitus can cause eye disorders, and 72.5% of the participants knew that regular eye examinations are recommended for diabetic patients. Adequate knowledge score was observed among diabetic patients aged 25-49 years (52.6%), with a university education (53.5%), with a history of diabetes for 10 years and more (60.5%), those on insulin therapy (55.3%), those adherent to their regular treatment (92.1%), and those getting their information from doctors (73.7%).Conclusions Diabetic patients had average knowledge about diabetic retinopathy but little awareness regarding the frequency of regular eye examinations and the physicians who should conduct them. Intensive health education concerning diabetic retinopathy should be conducted for diabetic patients and their caregivers to improve their perception and compliance with eye care and prevent visual damage in the Al Qunfudhah district.
