RESUMO
Objectives: Primary aim was to review the literature on the prevalence of diabetic retinopathy [DR] and Vision threatening diabetic retinopathy [VTDR] in Pakistan
Methods: A search of the bibliographic databases [Medline, Pub med, and Google scholar] was conducted from 1990 to March 2017. Articles about prevalence of DR and VTDR in Pakistan were retrieved and scrutinized. The studies satisfying the inclusion/exclusion criteria were considered for detail review
Results: Forty one articles on prevalence of DR were traced out. Exclusion and inclusion criteria were met in 29 studies. In selected studies [29], pooled Prevalence of DR was found to be 28.78% with a variation of 10.6% to 91.3%. Out of 29 studies, DR was classified in 19 studies. Pooled Prevalence of VTDR in these 19 studies was found to be 28.2% [variation of 4% to 46.3%] of patient with retinopathy and 8.6% of all diabetics
Conclusion: A great variation in the values of DR and VTDR was observed in this study. Researchers suggest a community based study with uniform methodology to find out a comparable value of prevalence of DR and VTDR in all provinces of Pakistan
