Aim: The aim of the study is to determinate the effect of diabetes mellitus (type 2) in central corneal thickness CCT, central macular thickness CMT and intra ocular pressure IOP. Material and Methods: A case control study was done at Al Faisal Eye Center, Riyadh - Khartoum in period from December 2018 to May 2019. The collected data included the demographic information of diabetic and non-diabetic subjects the examinations carried out were as follow: vision was assessed by a Snellen automated chart projector (Topcon ACP. 8), objective refraction was done by Auto Kerato Refactometer (TOPCON KR-8900), Intra ocular pressure was measured by AT 900 Goldmann tonometer (Haag-Streit international), Central corneal thickness CCT was taken by Ultrasonic Pachymeter (ACCUTOME- AccuPach V-) and central macular thickness was measured by Heidelberg Engineering OCT Spectralis without pupil dilatation .The collected data was analyzed statistically by use of the statistical package for social sciences (SPSS) version 16.0. Results: 70 subjects (35 cases of diabetic patients and other 35 subjects of non-diabetic controls) were investigated in this study; 60% males and 40% females but this is unlikely to cause a bias in results because diabetes and its related effects was not found as gender difference, their ages range from 43 to 69. Significant differences were found on the CCT for diabetic patients was (551.7± 19.8) which was more than the mean of non-diabetic patients was (538.2± 37.7) also p value <0.0001 .Central macular thickness CMT for diabetic subjects mean was (264.7± 6.19) which was more than CMT of non-diabetic (254± 8.33).There were no statistically significant differences in IOP between diabetic and non-diabetic group p value <0.0001. Conclusion: Our finding revealed an increase in corneal and macular thickness in diabetic (type 2) patients compared to non-diabetic group. There were no statistically significant differences in IOP between diabetic and non-diabetic group.
