En Face Imaging of Epiretinal Membranes and the Retinal Nerve Fiber Layer Using Swept-Source Optical Coherence Tomography.

BACKGROUND AND OBJECTIVE: To describe en face swept-source optical coherence tomography (SS-OCT) imaging of epiretinal membranes (ERMs) and the underlying retinal nerve fiber layer (RNFL).

PATIENTS AND METHODS: SS-OCT images were captured in nine eyes with ERMs. These SS-OCT en face images were qualitatively compared to spectral-domain OCT (SD-OCT) en face images. Using SS-OCT, en face images of the RNFL were obtained, if possible.

RESULTS: En face SS-OCT images of ERMs were obtained in all nine eyes of eight individuals with clinically diagnosed ERMs that were superior to SD-OCT images. Clear en face images of the RNFL were acquired in seven of nine eyes (78%) using SS-OCT.

CONCLUSIONS: SS-OCT is a novel method for generating en face images of ERMs. Compared with SDOCT en face images, SS-OCT could more clearly identify the plaques and folds of ERMs and underlying defects in the RNFL. Such images could be useful for surgical planning and assessment of the integrity of the underlying RNFL. [Ophthalmic Surg Lasers Imaging Retina. 2016;47:730-734.].
