# Suprachoroidal Triamcinolone Acetonide for the Treatment of Refractory Macular Edema Secondary to Non-Infectious Uveitis

## TL;DR

This study shows that suprachoroidal triamcinolone acetonide improves vision and reduces swelling in patients with severe, treatment-resistant eye inflammation.

## Contribution

The study provides early evidence of the safety and short-term efficacy of a newly FDA-approved treatment for refractory macular edema due to non-infectious uveitis.

## Key findings

- Median visual acuity improved from 20/100 to 20/40 at 1 month and 2–3 months.
- Central subfield thickness decreased significantly within the first 3 months of treatment.
- Improvements in vision and swelling were less pronounced at 6–12 months.

## Abstract

Suprachoroidal triamcinolone acetonide (TA) was recently FDA-approved and is emerging as a new alternative to other local therapies for macular edema (ME) associated with noninfectious uveitis (NIU).

This was a retrospective review of our initial experience with a cohort of patients with refractory ME secondary to NIU treated with suprachoroidal TA from November 2022 to October 2023. Data collected included demographics, ophthalmic history, as well as exam and imaging findings at baseline and follow-up visits.

Six eyes from 5 patients with refractory ME secondary to NIU were included in the study. The cohort included 2 females (40%) and the median age was 62 years (IQR = 8). Ophthalmic diagnoses included intermediate uveitis (n = 2; 40%), birdshot chorioretinopathy (n = 1; 20%), autoimmune retinopathy (n = 1; 20%), and panuveitis (n = 1; 20%). The median logMAR visual acuity was 0.7 (Snellen 20/100) at baseline and improved to 0.3 (Snellen 20/40) during follow-up visits at 1 month and 2–3 months. The median central subfield thickness (CST) was 690 μm at baseline and improved to 367.5 μm and 309 μm at the follow-up visits at 1 month and 2–3 months, respectively. The initial improvement in logMAR visual acuity and CST was less pronounced at follow-up visits at 6–7 months and 11–12 months.

This study demonstrates the safety of suprachoroidal TA and efficacy signals including improvement in visual acuity and ME at 3 months in patients with severe, refractory ME secondary to NIU.
