Uveitic Macular Edema: Clinical Outcomes in Real-World Practice

To examine the real-world management and outcomes of uveitic cystoid macular oedema (CME).

Retrospective study.

Patients with uveitic CME were identified from the Inflammatory Eye Disease database. 248 eyes of 218 patients with uveitic CME were identified. Main Outcome Measures: Time to resolution, time to recurrence and vision loss.

Median age at time of CME was 51.7 years [IQR 37.3-63.9]. Overall likelihood of resolution was 209/248 eyes (85.3%). Resolution occurred in 34.1% with topical therapy, 69.2% treated with oral prednisone (72.9% if prednisone dose ≥ 60 mg/day), 73.5% treated with orbital floor steroid, and 86.7% treated with intravitreal steroid. On multivariate analysis, ERM was associated with decreased resolution of CME (HR 0.735 p = 0.045). Additionally, infectious aetiology approached significance (HR 0.635 p = 0.059) for CME resolution. Recurrence occurred in 85 eyes (36.5%). Predictors of increased likelihood of recurrence were current smoking status (HR 1.818 p = 0.042) and subretinal fluid at diagnosis (HR 1.577 p = 0.043). Eyes with infectious aetiology had lower chance of CME resolution, but those that did resolve had lower probability of recurrence (HR 0.891 p = 0.019). Moderate vision loss (20/50-20/200) occurred in 24 eyes (9/7%) and severe vision loss (≤20/200) in 17 eyes (6.9%).

Management of CME is challenging given the heterogeneous aetiologies, severity of the macular edema as well as response to the therapy. A high rate of resolution was observed, given sufficient time, but recurrence occurs in one-third. Current smoking status plays an important role in the risk of recurrence of CME and patients should be encouraged to stop smoking.
