ABSTRACT

Abstract?AIM: To observe the effects of different antidiabetic therapies on macular thickness in diabetes patients without fundus complication.?METHODS: The macular thickness was measured by optical coherence tomography ( OCT) .The retina volume on the center of macula was scanned, and it generated automatically the average thickness data of three rings and nine areas of 1mm, 3mm and 6mm.The data were statistically analyzed.?RESULTS: Healthy control group, oral hypoglycemic drug group and insulin treatment group were enrolled. Each group included 22 cases 22 eyes.The macular retinal thickness of healthy control group is 268.09±17.97μm (the 1st ring), 340.41 ±22.25μm ( the 2nd ring) and 298.14 ± 12.90μm ( the 3 rd ring ) , respectively. The macular thickness of oral hypoglycemic drug group is 260.00 ± 18.17μm (the 1st ring), 335.44±21.12μm (the 2nd ring) and 295.63 ±15.92μm ( the 3rd ring), respectively.The macular thickness of insulin therapy group is 271.01 ± 26.09μm (the 1st ring), 340.86±17.10μm (the 2nd ring) and 298.57 ±12.14μm ( the 3rd ring ), respectively. Comparison of the macular thickness of the 1st ring among 3 groups was insignificant (F=1.21, P=0.31), neither the comparison of the 2nd ring (F=0.35, P=0.71), neither the comparison of the 3rd ring (F=0.22, P=0.81).? CONCLUSION: Compared with healthy individuals, both oral antidiabetic medicines and insulin therapy don't alter the macular thickness of patients with diabetes while without fundus complication.
