Several factors have been identified as determinants for the development of DR and its progression, including, type and duration of DM, age, gender, glycemic control, hypertension, the body mass index (BMI), smoking, serum lipids and presence of microalbuminuria (MA) (Cai et al., 2006; Parving et al., 2006). Myopia was suggested to have a beneficial effect against DR as early as 1965 by IS (Jain et al., 1965). Subsequently, several researchers also noted this association, but the underlying cause remained debatable (Wang et al., 2016; Yu Fu et al., 2016). Myopia is a common ocular condition affecting approximately 1.6 billion people worldwide and its prevalence is expected to reach 2.5 billion by the year
