Stepwise 900 µm to 1100 µm Microneedle Selection for Suprachoroidal Triamcinolone Acetonide

Abstract
Purpose
To describe real-world microneedle size use during suprachoroidal triamcinolone acetonide injection and identify patient-level factors associated with 900 µm vs 1100 µm microneedle requirement.
Methods
A retrospective study was performed of all eyes receiving suprachoroidal triamcinolone acetonide between November 2022 and May 2026 from a single provider at a tertiary referral center. The primary outcome was microneedle size requirement (900 µm vs 1100 µm) at the first injection. The secondary outcome was needle size transition on repeat injections among eyes initially injected with the 900 µm needle. Generalized estimating equations with patient-level clustering were used for the primary analysis. Safety outcomes were also assessed.
