    Purpose: To evaluate the efficacy and safety of preservative-free triamcinolone acetonide (Triesence) for the treatment of macular edema. Methods: A retrospective study was conducted on patients who attended a tertiary retinal clinic from June 2009 to July 2012 with macular edema due to various causes. Patients who received at least 1 intravitreal Triesence injection and completed 6 months of follow-up were recruited. Data, including best-corrected Snellen visual acuity, central macular thickness (CMT), intraocular pressure (IOP), and adverse events (AEs), were collected at baseline, week 1, month 1, month 3, and month 6 after initiation of treatment. Snellen visual acuity was converted to visual acuity score (VAS) for statistical analysis using paired t-tests and linear regression. Results: One hundred two eyes from 102 patients were included in the study. Mean VAS was significantly improved at all follow-up time points compared to baseline (P≤0.002), with highest mean gain at month 1 (6.1±8.9 letters). Mean CMT decreased significantly at all follow-up points compared to baseline (P≤0.0005), with the greatest reduction at week 1 (146.6±109.4μm). A total of 22 AEs were observed, and IOP elevation was the most common AE related to Triesence treatment (17/22, 77.3%). No sterile or infectious endophthalmitis was observed. Conclusion: Intravitreal Triesence improves visual acuity and reduces macular thickness in eyes with macular edema from various causes. Treatment-associated IOP elevation was manageable with antiglaucoma medications. There were no serious vision-threatening complications associated with intravitreal Triesence therapy during the study period.
