Abstract

Purpose:

The purpose of this study was to investigate the sensitivity of various scan modes of spectral-domain optical coherence tomography (SD-OCT) for detecting pathologies that may accompany myopic foveoschisis, which is important for making surgical decisions and planning surgical strategies for myopic foveoschisis.

Methods:

Twenty-one eyes of 18 patients were diagnosed with myopic foveoschisis by SD-OCT. Patients were examined with SD-OCT using both a five-line raster scan and a three-dimensional scan at the same visit. The detection rates of pathologies such as macular hole, epiretinal membrane, retinal vascular microfolds, internal limiting membrane detachment, paravascular microhole, and photoreceptor inner and outer segments defect were compared between modes.

Results:

The three-dimensional scanning mode of the SD-OCT tended to be superior to both the one-line and five-line raster scanning modes for detecting inner and outer segments, epiretinal membrane, macular hole, paravascular microhole, and internal limiting membrane. The three-dimensional mode had a significantly higher detection rate (71%) of retinal vascular microfolds than both the 1-line (19%, P < 0.01) and 5-line raster scanning modes (33%, P < 0.05).

Conclusion:

The three-dimensional scan mode of SD-OCT was more sensitive for detecting the pathologies that accompany myopic foveoschisis, providing important information for vitreous surgery.
