Evaluation of macular changes after uneventful phacoemulsification surgery in diabetic patients using fluorescein angiography and optical coherence tomography

Background: Macular edema (ME) is a major cause of vision loss after cataract surgery in diabetic patients. Proper and early diagnosis of post-cataract complications is of utmost importance. Aim: to evaluate the influence of uncomplicated phacoemulsification on macular thickness and macular changes in the postoperative period in diabetic patients. Patients and methods: This study included 100 eyes of cataractous patients attending the outpatient ophthalmology clinic of Al-Azhar University hospital. The included patients were classified into 2 groups: the first included 50 eyes of diabetic patients with no clinical fund us changes, and the second included 50 eyes of normal patients. All patients were submitted to full history taking, clinical and ophthalmological examination. All were evaluated preoperatively and postoperatively at one day, one weak, one month, 3 and 6 months. Results: There was significant decrease in study group when compared to control group as regard to preoperative BCVA (0.95±0.12 vs 0.86±0.17 respectively). There was significant improvement of BCVA postoperatively when compared to corresponding preoperative values in both groups, while IOP revealed that, there was no significant difference at 1, 3 and 6 months when compared to corresponding values at 1 week. Postoperative fundus examination revealed that, there was no abnormality detected at 1 week postoperative; while at 1 month, 5 eyes (10.0%) in diabetic group and 3 eyes (6.0%) in non-diabetic group showed lost foveal depression and macular thickening. CSFT (Central Subfield Foveal Thickness) revealed that, there was no significant difference between diabetic and non-diabetic groups preoperatively; but at 1, 3 or 6 months postoperatively, there was significant increase of CSFT in diabetic group when compared to non-diabetic group. In addition, there was significant increase of CSFT at 1, 3 and 6 months PO when compared to corresponding preoperative values in each group separately. Conclusion: There is a subclinical increase in central retina thickness in diabetic and non-diabetic patients after uncomplicated phacoemulsification, which may be detected clinically and by FFA also can be quantified by OCT.
