The goal of this study is to learn if a suprachoroidal triamcinolone injection can treat vision-threatening swelling in the center of the retina (macular edema) caused by non-infectious uveitis, especially in people who did not improve after a standard steroid injection around the eye (sub-Tenon injection). The main questions it aims to answer are: Does vision improve on the eye chart after the injection? Does the injection lower retinal swelling (reduction in thickness) within 3 months? Participants will: Have a pre-treatment check (vision test, slit-lamp exam, and a retinal scan called OCT). Receive one suprachoroidal triamcinolone injection under anesthetics drops in a sterile setting (operating room) with standard monitoring. Return for visits about 1 month and 3 months after treatment for repeat vision tests, and OCT scans. Contact the clinic if they notice pain, redness, new floaters, or worsening vision.
