Intraoperative OCT may impact decision-making during vitreomacular traction surgery

Subclinical findings on optical coherence tomography during vitreomacular traction surgery can affect decisions made during the course of the surgery, according to study findings.
The retrospective, consecutive case series included 12 eyes of 12 patients who underwent 23- or 25-gauge three-port pars plana vitrectomy (PPV) repair of vitreomacular traction (VMT). All patients had preoperative spectral-domain OCT scanning to verify the presence of VMT. Researchers analyzed clinical characteristics and findings from intraoperative OCT images.
Patients’ mean visual acuity improved from 20/51 to 20/72. At the time of PPV, all eyes were pseudophakic, except for four that were phakic; three of the phakic eyes required cataract extraction with IOL placement at the time of PPV, according to the researchers.
Intraoperative OCT highlighted the presence of microarchitectural changes, particularly in the outer retina with increased subretinal hyporeflectivity, after the release of VMT. The researchers found that in five of the eyes analyzed, these intraoperative OCT findings altered the initial surgical plan in order to address issues such as full-thickness macular hole formation and residual membrane.
