BACKGROUND: Anti-vascular endothelial growth factor (VEGF) treatments are the first-line treatment for Retinal Vein Occlusion (RVO). Although effectiveness and safety of these treatments is well documented, knowledge regarding the effect of lapses in anti-VEGF treatment among RVO patients is lacking. The purpose of this study is to analyse the anatomic and visual outcomes from a lapse in anti-VEGF treatment in patients with RVO.
METHODS: This retrospective case-control study evaluated 136 patients diagnosed with RVO and treated with anti-VEGF between January 2012 and June 2020 at Cole Eye Institute, Cleveland Clinic. Patients were divided into two cohorts: RVO patients with no lapse in anti-VEGF treatment (control group) and RVO patients with a lapse ≥3 months (lapse group). Central subfield thickness (CST) and best corrected visual acuity (BCVA) were collected pre-lapse, the first appointment post-lapse, and at 3-, 6-, and 12-month follow-up appointments.
RESULTS: Lapse patients (n = 68) and control patients (n = 68) had similar pre-lapse CST (p = 0.466) and BCVA (p = 0.303). Lapse patients experienced a significant increase in CST after discontinuing anti-VEGF therapy (lapse: 400.6 ± 192.1 µm, control: 333.0 ± 111.1 µm, p = 0.024). This persisted 12 months post-lapse after re-initiation of anti-VEGF agents (lapse: 381.6 ± 161.1 µm, control: 307.5 ± 95.4 µm, p = 0.030). Lapse patients also experienced a decrease in BCVA after lapse (lapse: 54.3 ± 25.1 ETDRS, control: 64.4 ± 17.8 ETDRS, p < 0.001) that recovered after 6 months of anti-VEGF treatment.
CONCLUSIONS: RVO patients with any lapse of anti-VEGF treatment are at risk for poorer anatomic and visual outcomes. Though BCVA normalizes upon treatment resumption, patients experience a statistically significant increase in CST that does not recover.
