Aim: To evaluate macular thickness and retinal nevre fiber thickness measurements with OCT in type 1 and type 2 diabetes mellitus patients without retinopathy and to compare these results with normal group.Materials and Methods: Fifty type 1 and 50 type 2 diabetes mellitus patients without retinopathy and 50 volunteers without diabetes mellitus were enrolled in this study.BCVA of all patiens and all volunteers were determined and detailed anterior and posterior segment examinations were done. Intraocular pressures were evaluated using Goldman aplanation tonometer. Each eye of patiens and normal group vere scanned with OCT using fast macular thickness and macular thickness protochols. Retinal thickness (RT) and total macular volum (TMV) were calculated automatically in central 1 mm area using retinal thickness/volume protochol. Groups were compared to each other according to horisontal scannings in central 1 mm area and TMV measurements. Retinal nevre fiber layer (RNFL) thickness measurements of 50 eyes of each 25 type 1, 25 type 2 and 25 volunteers were done using RNFL Thickness Average method and evaluated in superior, temporal, nasal and inferior areas.Results: RT was 186.02 ± 30.138 µ (112-272) in type 1 DM patiens, 195.92 ± 25,445 µ (118-274) in type 2 DM patients and 195.92 ± 28.824 µ (136-295) in normal group in central 1 mm area. Retinal thickness average was found significantly lower in type 1 DM patiens according to other 2 groups (p=0.017). TMV was 6.811 ± 0.5740 mm³ (3.5-7.9) in type 1 DM patients, 6.857 ± 0.5120 mm³ (4.9-9.2) in type 2 DM patients and 7.027 ± 0.6501 mm³ (5-10) in normal group. TMV was lower than type 2 DM patients and control group and difference between type 1 DM patients and control group was significantly important (p=0.023). RNFL thickness was 77.72 ± 14.43 µm (48-125) in type 1 DM patients, 68.08 ± 15.72 µm (42-108) in type 2 DM patients and 73.74 ± 25.25 µm (38-194) in control group in nasal area. Difference between type 1 DM patients and type 2 DM patients in nasal area was ...
