En face enhanced-depth swept-source optical coherence tomography features of chronic central serous chorioretinopathy.

ABSTRACT:

Objective

To characterize en face features of the retinal pigment epithelium (RPE) and choroid in eyes with chronic central serous chorioretinopathy (CSCR) using a high-speed, enhanced-depth swept-source optical coherence tomography (SS-OCT) prototype.

Design

Consecutive patients with chronic CSCR were prospectively examined with SS-OCT.

Participants

Fifteen eyes of 13 patients.

Methods

Three-dimensional 6×6 mm macular cube raster scans were obtained with SS-OCT operating at 1050 nm wavelength and 100000 A-lines/sec with 6 μm axial resolution. Segmentation of the RPE generated a reference surface; en face SS-OCT images of the RPE and choroid were extracted at varying depths every 3.5 μm (1 pixel). Abnormal features were characterized by systematic analysis of m
