The Comparison of Intraocular Pressure Elevation after Intravitreal Injection of Different Concentration of Triamcinolone Acetonide

Purpose: The purpose of this study was to compare the effects of intravitreal injections of 4 mg or 8 mg triamcinolone acetonide(TA) on intraocular pressure (IOP) in macular edema. Methods: This was a retrospective study conducted by reviewing follow-up records for the eyes of 60 patients with macular edema 6 months receiving a intravitreal TA injection. Two groups, A and B, who had received TA injections of either 4 or 8 mg, respectively, were compared. Results: The average pre-injection IOP for group A was 12.8±2.6 mmHg, and the average post-injection IOP at 1 day, 1 week, 1 month, 3 months, and 6 months was 15.0±2.7, 14.6±3.2, 15.3±3.5, 15.8±4.0, and 14.4±2.8 mmHg, respectively. The average pre-injection IOP for group B was 12.5±2.4 mmHg, and the average post-injection IOP at 1 day, 1 week, 1 month, 3 months, and 6 months was 14.9±2.9, 14.3±3.0, 14.7±3.2, 15.2±4.4, and 14.5±4.5 mmHg, respectively. The difference in IOP elevation between the two groups was not statistically significant (p>0.05). Conclusions: There was no statistically significant difference between a 4 mg or 8 mg intravitreal TA injection with respect to IOP elevation.
