BackgroundCataract is an extremely serious cause of visual impairment in paediatric patients worldwide, with untreated cataract being the leading cause of blindness in children.AimsThe aim of the present study was to assess the level of awareness and knowledge about paediatric cataract among the general population of Jeddah, Saudi Arabia.Methods This survey-based cross-sectional study was conducted between June and July 2018 and included a representative sample of the general population of Jeddah, Saudi Arabia. The questionnaire included a set of questions pertaining to paediatric cataract knowledge and awareness. The gathered data were analysed using Statistical Package for Social Sciences (SPSS) version 21, and the results were acquired by Pearson’s chi square tests and frequency calculations.Results In total, 678 individuals, including 51.6per cent women and 48.4per cent men, participated in the survey. Approximately 39.7per cent participants did not know whether cataract can affect the paediatric population or not. Although the majority could not recognize the risk factors and symptoms of the disease, 75.2per cent realized that it is treatable. Surgical intervention was identified as the main treatment modality by 46.9per cent participants.ConclusionOur findings suggest that the general population of Jeddah has limited knowledge about paediatric cataract. Thus, educational campaigns and programs are necessary to increase public awareness. In addition, further studies on awareness about this condition should be considered in order to prevent serious eye complications in children
