RETINAL IMAGING WITH HIGH-RESOLUTION HIGH-SPEED OPTICAL COHERENCE TOMOGRAPHY IN PATIENTS WITH NYSTAGMUS

Abstract

To compare the quality of retinal images in patients with nystagmus made by the Spectral Domain High-Resolution High-Speed Optical Coherence Tomography Copernicus (SD-OCT) and by the Time Domain Stratus Optical Coherence Tomography (Stratus-OCT).

Three patients with a congenital horizontal nystagmus and various retinal features were tested with both the SD-OCT (Optopol, Rockmed, Poland) and the standard Stratus-OCT (Carl Zeiss Meditec, Dublin, CA).

Stratus-OCT exhibited “saw tooth” or waved images in all three patients with nystagmus and failed to discriminate the retinal layers. In contrast, the SD-OCT imaging gave clear representation of the retina with discrimination of intraretinal layers in all three patients.

The high speed and resolution of SD-OCT resulted in discrimination of intraretinal layers in patients with nystagmus and indicates the potential of SD-OCT in diagnosing retinal disorders in patients with nystagmus.
