Real-time OCT for study of cornea of living Indian frogs and toads

Kumari S*, Nirala AK

A high-speed Optical Coherence Tomography (OCT) system based on single mode fiber which can capture eight images per second was used to acquire OCT images of the eyes of Indian frogs and toads. The axial resolution of the set up was estimated to be 18 m. With these OCT images, the ocular parameters, viz. corneal thickness, anterior chamber depth and anterior chamber angle were estimated. The thickness of the cornea of frog and toad is found to be 136.12 m and 100.66 m respectively. Measurement of corneal thickness is needed in many physiological and clinical studies and is helpful in diagnosis of several corneal disorders.
