| Résumé: | Copyright 2013, SLACK Incorporated. An accurate analysis of the thickness and volume of choroid using optical coherence tomography (OCT) requires precise visualization of the choroido-scleral interface. Results of studies that use spectral-domain OCT (SD-OCT) to look at the percent visualization of the choroido-scleral interface for accurate analysis of choroidal thickness show varying success rates. This study assessed the visualization of choroido-scleral interface in 19 healthy participants (19 eyes) prospectively recruited for consecutive high-definition raster scanning with an SD-OCT system with and without enhanced depth imaging (EDI) and a prototype long-wavelength swept-source OCT (SS-OCT) system. Choroido-scleral interface was visualized in all eyes imaged on SS-OCT, compared with 13 of 19 (68.4%) and 14 of 19 (73.6%) eyes imaged on SD-OCT without EDI (P = .009) and with EDI (P = .02), respectively. The prototype long-wavelength SS-OCT system, with its higher acquisition speed and deeper tissue penetration, may have better clinical utility in determining the involvement of choroid in various chorioretinal diseases |
