5M.D. Asistant Professor, Yıldırım Bayazıt University Department of Ophthalmology, Ankara/TURKEY Purpose: In this study, we aimed to assess the effectiveness of a single sub-tenon injection of triamcinolone acetonide on the development of cystoid macular edema (CME) detected by ocular computed tomography (OCT) in diabetic patients after cataract surgery.
Materials and Methods: In this prospective, randomized controlled study, we included 40 eyes of 31 patients with type 2 diabetes mellitus who underwent phacoemulsification and intracapsular lens implantation without any complication. The control group comprised eyes not treated with a triamcinolone acetonide injection, and the subtenon group comprised eyes treated with a single posterior sub-tenon injection of triamcinolone acetonide. Best corrected visual acuity, intraocular pressure (IOP), CME development were compared between the two groups preoperatively and at postoperative 1st week, 1st month.
Results: The subtenon group comprised 20 eyes and the control group, 20 eyes. There was no statistically significant difference between the 2 groups in the mean corrected distance visual acuity at any follow-up examination (p>0.05). At postoperatif 1st month, four eyes in the control group and no eye in the subtenon group developed CME (p=0.048). IOP was not developed in any eyes which necessitated topical medication.
Conclusion: Although, a single posterior subtenon injection of triamcinolone acetonide significantly reduced the incidence of CME in diabetic patients after phacoemulsification surgery, no effect on visual acuity and IOP was observed.
