Vitreomacular Traction Surgery from the DISCOVER Study: Intraoperative OCT Utility, Ellipsoid Zone Dynamics, and Outcomes.

Background And Objectives: To characterize the clinical and ellipsoid zone (EZ) integrity outcomes in surgical intervention for symptomatic vitreomacular traction (VMT), and to evaluate the utility of intraoperative optical coherence tomography (OCT) during VMT surgery.

Patients And Methods: This was a post-hoc analysis of eyes in the DISCOVER study undergoing pars plana vitrectomy (PPV) with intraoperative OCT for VMT-related macular disease. Data were collected prospectively on feasibility and utility of intraoperative OCT, with follow-up lasting 12 months.

Results: Forty-three eyes of 41 patients were included and mean visual acuity improved from 20/96 to 20/45 ( < .001). Intraoperative OCT provided information that impacted surgical decision-making in eight patients (18.6%). EZ integrity metrics significantly improved from baseline to 12 months and directly correlated with functional outcomes ( < .001).

Conclusions: Retinal function and morphology improved significantly following PPV for VMT. Intraoperative OCT provided surgeon-perceived valuable information in select cases. Further research is needed to determine whether this information impacts overall surgical outcomes. .
