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.
Results : 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.
Conclusion : PSTA is a relatively safe treatment method after IVTA injection regardless of steroid
responsiveness.
