[Ocular abnormalities in patients with prediabetes].

Prediabetes is recognized as the major risk factor for type 2 diabetes. Nearly 7% of adults worldwide are estimated to have prediabetes and the prevalence is increasing. There is evidence of microvascular and macrovascular complications in patients with prediabetes. Early detection of prediabetes and lifestyle modification could therefore contribute to the prevention of type 2 diabetes and its complications. Many reports indicate the possibility of ocular abnormalities in prediabetes. A number of studies show associations between prediabetes and early forms of retinopathy. There is also evidence that colour vision and contrast sensitivity are impaired in these patients. Our study analyses data regarding ocular abnormalities in prediabetes.
