To evaluate the efficacy and safety of posterior subTenon triamcinolone acetonid injection in diabetic macular edema cases


13 eyes of 12 diabetic macular edema patients ( 7 M, 5 F ) were enrolled into this retrospective study. 40 mg triamcinolone acetonide was injected into the subTenon space via blunt tip cannula through a minor conjunctival incision in the inferonasal quadrant posteriorly. Preinjection, and postinjection at 3th month visit, central macular thickness (CMT ), best corrected visual acuity (BCVA; Snellen), and intraocular pressure (IOP) values were evaluated. SPSS 18 was used for statistical analysis.


Mean pretreatment CMT value was decreased from 477 µm to 319 µm ( p<0,001). Mean BCVA increased from 0,32 lines to 0,5 at 3th month ( p<0,05). Mean IOP value increased from 14,77 to 16,38 mmHg (p>0,05). Anti-glaucomatous agents were not indicated in any cases. Side effects such as endophthalmitis or cataract progression were not seen in the follow-up.


Posterior SubTenon triamcinolone injection is an effective and safe treatment modality in diabetic macular edema cases. Long-term folow-up is needed for further evaluation.
