Abstract Details

PURPOSE:To describe the clinical relevance of en face spectral domain optical coherence tomography (SD-OCT) of the retinal surface before and after epiretinal membrane (ERM) and internal limiting membrane peeling.

Setting:

Ophthalmology department of Centro Hospitalar do Porto in Porto, Portugal.

Methods:

Retrospective analysis of preoperative and postoperative en face SD-OCT images of the inner face of the macula obtained from 15 eyes of 15 patients that underwent vitrectomy with internal limiting membrane peeling for ERM.

Results:

Preoperatively, en face SD-OCT imaging of the retinal surface showed plaques surrounded by radiating folds because of ERM, and areas possibly devoid of internal limiting membrane secondary to ERM contraction. Postoperatively, a rough retinal surface was visible in the peeled area during the first month. Posteriorly, in the majority of patients, dimples were progressively observed, and some residual epiretinal tissue was also detected.

Conclusions:

En face SD-OCT of the retinal surface is an interesting complement to standard retinal OCT section that provides a global overview of the retinal surface. It can detect and classify tiny progressive morphologic changes in the texture of the retinal surface occurring after internal limiting membrane peeling.
