Why the study?
Does axial myopia correlate with a lower prevalence of diabetes and diabetic retinopathy in patients undergoing ophthalmic surgery?
Does axial myopia correlate with a lower prevalence of diabetes and diabetic retinopathy in patients undergoing ophthalmic surgery?
Axial myopia is negatively correlated with HbA1c levels and the prevalence of diabetes and diabetic retinopathy.
Longer axial length was associated with lower diabetes/DR prevalence; hypothesis-generating and requires prospective validation before clinical consideration.
The aim of this study was to investigate whether axial myopia has a suppressive effect on diabetes and diabetic retinopathy. Methods: This retrospective, cross-sectional study used propensity-score matching to explore the correlations between axial myopia and diabetes and diabetic retinopathy. This study included patients who underwent ophthalmic surgery, including cataract surgery, between April 2009 and July 2016. Results: With an increase of the axial length (AL < 24 mm; 24 mm AL < 26 mm; and AL 26 mm) in axial myopia, the prevalence of diabetes (35.9%, 27.9%, and 20.1%, respectively) and diabetic retinopathy (43.3%, 31.2%, and 24.1%, respectively) decreased (p < 0.001 and = 0.001, respectively). Similarly, glycosylated hemoglobin (HbA1c) level (7.00%, 6.67%, and 6.44%, respectively) decreased with an increase of AL in axial myopia (p < 0.001). Axial length and HbA1c level were significantly and negatively correlated, as determined by partial correlation analysis after adjusting for age and sex (r = -0.127; p < 0.001). Conclusions: Axial myopia and low HbA1c level are correlated and have a suppressive effect on diabetes and diabetic retinopathy.
