|b BACKGROUND: Macular edema is an increase in macular thickness due to fluid accumulation in the macula in patients with diabetes mellitus. Optical coherence tomography (OCT) has been shown to be highly reproducible in measuring macular thickness in normal individuals and diabetic patients. OCT can detect subtle changes of macular thickness. The aim of this study is to investigate the changes of refractive status of the eye and visual acuity post photocoagulation in diabetic macular edema. Subjects and methods: A cross sectional hospital-based study was done at Al Faisal Eye Center, Riyadh - Khartoum in period from January to December 2017.Central macular thickness (CMT) pre and post photocoagulation was measured using optical coherence tomography (oct), vision and best-corrected visual acuity (BCVA) was measured using Snellen chart, refractive status was measured using auto refract meter, data were taken from records of the patient who attend to the hospital. Results: The study was conduct 120 (240 eyes) 132 males (55%) and 108 females (45%), their ages ranged between (40-65) years with mean of 55.3±7.44 years. Paired sample t-test showed no significant differences between patient’s vision pre and post photocoagulation treatment with mean 0.39±0.29 and 0.40±0.30 respectively, P value 0.116. Another measure by paired sample t-test showed no significant differences between patient's visual acuity mean pre and post-photocoagulation was 0.61±0.32 and 0.62±0.31 respectively, P value 0. 198. Considering the refractive state of the eye the study revealed slightly influenced with non-significant differences pre and post photocoagulation with hypermetropic mean 2.48±1.64 and 2.60±1.69 respectively and mean for myopic pre and post photocoagulation 1.66±1.46 and post 1.72±1.40 respectively with range 0.25± 7.00. Significant differences were found only on the upper and temporal macular thickness pre and post photocoagulation, comparison of average macular thickness pre and post photocoagulation revealed significant differences p value (0.009) and (0.001) respectively. Conclusion: The study revealed that diabetic macular edema leads to slightly blurry vision to noticeable vision loss, the treatment influenced upper and temporal macular thickness otherwise make slightly changes in vision and refractive states.
