Purpose:
|
To evaluate the effect of high myopia on the incidence and severity of diabetic retinopathy.
|
|
Methods:
|
This study was an observational, paired matched, contralateral eye study in which 58 diabetic patients, with myopic anisometropia greater than -6 diopters, were selected among 1450 diabetic patients. The myopic eyes were selected as the case group and compared with non-myopic contralateral eyes. Main outcome measures were the presence and severity of diabetic retinopathy
|
|
Results:
|
Fifty eight patients with a mean age of 60.3 ± 12.1 years, 22 males and 36 females were evaluated. Sixty percent of patients had type 1 diabetes mellitus. Mean refractive error was -9.5±2.1 diopters in myopic eyes and +0.5 diopters6±1.7 in non-myopic eyes (P=0.001). Mean axial length was 26.89±0.75 mm in the myopic eyes and 23.25±0.65 mm in the non-myopic eyes (P=0.035). Diabetic retinopathy was present in all non-myopic eyes, however, it was observed only in 16 (27.59%) myopic eyes (P=0.006). Also, myopic eyes had lower stages of diabetic retinopathy (P=0.001).

|
Conclusion:
|
Axial elongation in high myopia seems to be protective against incidence and progression of diabetic retinopathy.
