PURPOSE: To evaluate accommodative amplitude (AA) and fusional vergence amplitudes (FVA) in type 2 diabetes mellitus (DM) patients without diabetic retinopathy (DR).
MATERIALS AND METHODS: This study of 30 type 2 diabetic patients aged 35-50 years and 31 healthy subjects analyzed FVA, objective AA measurement and statistical evaluation. The study also evaluated the effects of mean HbA1c, age, and DM duration on AA.
RESULTS: The groups were similar in age (P=0.535). There were statistically significant differences between the groups in terms of mean convergence amplitude at distance (P=0.003), divergence amplitude (P=0.002) and mean convergence amplitude at near (P=0.001). Mean divergence amplitude at near (P=0.063) and near convergence point measurements (P=0.586) were not statistically different. AA was 0.52±0.3D in the DM group and 0.88±0.4D in the control group (P<0.001). Age was negatively correlated with AA in both groups (r1=-0.492, P1=0.003 and r2=-0.844, P2<0.001). Multivariate regression analysis showed that age influenced AA in patients with an R2 value of 0.179 (P=0.044).
CONCLUSION: Compared to healthy controls, type 2 DM patients without DR had lower accommodative and convergence amplitudes, suggesting that type 2 DM patients may develop presbyopia at an earlier age.
