Optical Coherence Tomography Anatomic and Temporal Biomarkers in Uveitic Macular Edema.

Journal Article (Journal Article)

PURPOSE: To assess the relationship between best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) features in noninfectious uveitis (NIU)-related macular edema. DESIGN: Clinical cohort study from post hoc analysis of 2 phase 3 clinical trials. METHODS: Correlation and longitudinal treatment analyses were performed. Of 198 patients with NIU, 134 received suprachoroidal CLS-TA (proprietary formulation of a triamcinolone acetonide injectable suspension), and 64 received sham, with 12.9% and 72%, respectively, receiving rescue therapy. RESULTS: At baseline, mean BCVA progressively worsened with each ordinal drop in central subfield ellipsoid zone (EZ) integrity. Eyes with normal baseline EZ experienced greater 24-week change in BCVA versus those with some degree of baseline EZ disruption (11.9 vs 9.4 letters, P = .006). In contrast, eyes with baseline central subfield cystoid spaces and/or subretinal fluid showed more improvement (13.7 or 17.2 letters, respectively) at 24 weeks, versus those without such findings (5.5 [P = .012] or 9.5 letters [P < .001], respectively). Longitudinal modeling for CLS-TA-treated eyes showed that central subfield thickness (CST) reached 90% of maximal improvement by week 3, whereas 90% maximal response in BCVA was not reached until week 9. CLS-TA-treated eyes that showed CST reduction of ≥50 µm at 4 weeks experienced a greater 24-week improvement in BCVA versus those without such an early response (14.6 vs 6.5 letters, P = .006 for difference). CONCLUSIONS: Pretreatment EZ integrity and the presence of central subfield cystoid spaces or subretinal fluid each predict improved therapeutic response to treatment in eyes with NIU. In CLS-TA treated eyes, longitudinal modeling shows CST improvement preceding BCVA improvement.
