Abstract

Purpose: : To evaluate the diagnostic potential of a slit-lamp adapted spectral radar optical coherence tomography as an in vivo imaging device for routine clinical examination of the anterior and posterior segment of the eye.

Results: : Our slit-lamp adapted SR-OCT system allowed direct biomicroscopic imaging. Anatomical structures and pathological changes were illustrated with high resolution and excellent contrast. In comparison to time domain systems of the anterior segment images (SL-OCT), SR-OCT exhibited a higher resolution providing more clinically relevant details (e.g. corneal stroma, filtering blebs). Due to the backscattering properties of the anterior part of the sclera at 830nm our system was not sufficient for completely imaging the anterior chamber angle. In posterior segment imaging, SR-OCT displayed a fine description of the macula and optic nerve head details with distinct analysis of macular pathology and retinal edema. A scan rate of 5000 Hz was sufficient while using a handheld lens. Our slit-lamp mounted SR-OCT was time-saving without shifting the patients between different sites and devices.
