A retinal tracker was integrated into a third-generation commercial clinical optical coherence tomography system (Stratus OCT) manufactured by Carl Zeiss Meditec Inc. (CZMI). The instrument, called tracking optical coherence tomography (TOCT), uses a secondary sensing beam in a confocal reflectometer and steering mirrors to compensate eye motion with a closed loop bandwidth of 1 kHz and a lateral accuracy of less than 15 μm. Imaging and tracking control systems have been integrated into a single platform and user interface in order to admit new imaging capabilities and considerable simplification in acquisition of clinical data. The system was configured to acquire three-dimensional retinal OCT maps through all subject eye movements and blinks.
