To explore the distribution of ocular, corneal and internal higher order aberrations (HOAs) in insulin-dependent (IDDM) and non-insulin-dependent (NIDDM) diabetic patients
Oftalmar. Medimar International Hospital. Alicante
Total, corneal and internal HOAs were in fourteen IDDM and twenty-two NIDDM eyes using ray tracing aberrometry (i-Trace, Tracey Technologies Corp., Houston, TX) and Scheimpflug imaging (Pentacam, Oculus Inc. Germany).
Total HOA was slightly higher in IDDM (0.634 ± 0.23µm) than in NIDDM patients (0.527 ± 0.24µm) (p>0.05). No significant differences in total, internal or corneal wavefront aberrations between IDDM and NIDDM were found. The greatest contributor of total optical aberration was internal coma 1 (Z3-1) for both diabetic groups. In NIDDM, age and CCT were correlated with total HOA (p<0.01), ACD and ACV were inversely correlated with total HOA (p<0.05). In IDDM there were not significantly correlations between HOAs, ocular parameters and age (p>0.05).
Diabetic patients showed high values of total and internal coma 1 (Z3-1). These increases were primarily due to changes in the crystalline lens. Optical quality measurements may be used as an aid for monitoring changes related to DM
