Posterior Subtenon Injection of Triamcinalone Acetonide for Cystoid ...

clinics and improves patient’s compliance with this
therapy.
Marco (17) reported a significant rise in IOP from
the baseline measurements in eyes with diffuse
diabetic macular edema after four weeks of PSTI. In
our study, a significant rise in IOP from the baseline
was noted in two eyes after the first week of PSTI.
These eyes were treated with antiglaucoma drugs for
a short time period (5.5 month).
Other possible complications of posterior
subtenon corticosteroid injection include ptosis,
cataract formation, inadvertent globe perforation. (15)
Conclusion
PSTI of 40mg TA through a superotemporal
approach appears to be safe and effective for shortterm
management of diabetic CME.
