The Influence of Axial Myopia on Diabetic Retinopathy

ABSTRACT

PURPOSE: To investigate the association of axial myopia with the incidence and progression of diabeticretinopathy. METHODS: One hundred eyes of diabetic group and one hundred eyes of non-diabetic group were included. We divided one hundred eyes of diabetic group into 5 groups according to their axial length, compared the incidence and progression of diabetic retinopathy at first hospital visit and after three year follow up. RESULTS: In severe myopic eye(axial length>28mm), the grade of diabetic retinopathy incidencence at the first visit is 1.23(near mild non proliferative diabetic retinopthy) and the grade of diabetic retinopathy progression is 1.17(nearly no change between the first hospital visit and after three year follow up). We found that axial length is inversely related with incidence and progression of diabetic retinopathy. CONCLUSION: From this result, we knew that axial myopia is protective for the development of diabetic retinopathy and we suggest there'll be association with decrease in ocular perfusion pressure and axial myopia patients with diabetic retinopathy.
