Comparison of central macular thickness measured by three OCT models and study of interoperator variability.

Purpose: To compare central macular thickness (CMT) measurement on healthy patient using 3 different OCT devices by two operators.

Methods: Prospective, monocentricstudy. Right eye's central macular thickness (CMT) of 30 healthy patients has been measured three times using a time-domain (TD) OCT (Stratus OCT, Carl Zeiss Meditec, Dublin, Ca) and two spectral domain (SD) OCTs (Cirrus HD-OCT, Carl ZeissMeditec, Dublin, Ca) and 3D-OCT 1000 (Topcon, Tokyo, Japan) by two operators.
