PURPOSE: To assess a new non-contact anterior optical coherence tomography (OCT) system for anterior chamber evaluation.
METHODS: A new commercial 131-nm infrared light anterior OCT system was used for anterior chamber evaluation. Forty-four eyes of 35 subjects (18 normal subjects, 17 subjects with anterior chamber abnormalities) were enrolled in the study.
RESULTS: Eyes were divided into those with narrowed, broadened and normal anterior chamber depth. Anterior chamber angle dynamics were assessed in three patients with angle-closure glaucoma and cataract extraction. Anterior OCT was also used for visualization of the anterior chamber (OCT goniometry) in a subject with multiple local anaesthetic allergies with phobia regarding conventional contact gonioscopy.
CONCLUSIONS: Anterior OCT is a new, easy-to-handle, non-contact technique that allows exact evaluation of anterior chamber parameters such as anterior chamber depth, chamber angle dynamics, corneal curvature and corneal thickness.
