RESUMEN
AIM: To study central corneal thickness ( CCT ) and correlation in different degrees of diabetic retinopathy ( DR) . METHODS:A total of 65 cases (130 eyes) with different degrees of DR and 35 normal cases (70 eyes) as the age-and gender-matched control group were examined by corneal endothelial microscope, to measure CCT and statistics RESULTS: Compared to control group, there were no significant difference of CCT both mild and medium nonproliferative diabetic retinopathy ( NPDR) groups ( P>0. 05 ). While the CCT of severe NPDR group and proliferative diabetic retinopathy ( PDR ) group were thicker than control group, and the differences were statistically significant (P CONCLUSION: The CCT increases with severity of DR. Taking care of protecting corneal endothelium is very important in the time of therapeutic measure, especially intraocular operation, to decrease complication.
