The Intraocular Pressure Rise Secondary to Subtenon’s Injection of Triamcinolone After Intravitreal Injection

`Purpose: To evaluate the safety of posterior subtenon’s injection of triamcinolone acetonide (PSTA) after intravitreal triamcinolone acetonide injection (IVTA). Methods: We reviewed the charts of 34 patients who had previously treated with IVTA. Patients were categorized as steroid responder or non-responder. Responders were defined as having a relative intraocular pressure increase of 5 mmHg and absolute intraocular pressure greater than 24 mmHg. Relative risk of intraocular pressure was prospectively evaluated after PSTA. Result: Eighteen eyes were categorized as steroid responders after IVTA injection and sixteen eyes were categorized as non-responders. For the actual amount of increase in the intraocular pressures, the steroid responder group (39%) was shown to be statistically higher than the non-responder group (6%) (P=0.044). However, the mean pressure values did not show a significant difference (P>0.05). Only one eye required the use of glaucoma medications and the intraocular pressure remained normal after treatment. Conclusions: PSTA is a relatively safe treatment method after IVTA injection regardless of steroid responsiveness.`
