Abstract

Optical coherence tomography (OCT) has had a tremendous global health impact upon the current ability to diagnose, treat, and monitor multiple eye diseases. We propose that a miniature forward-imaging OCT probe can be developed for real-time ocular imaging. A miniature 25-gauge forward-imaging probe was designed and developed to use with an 850 nm spectral-domain optical coherence tomography (SDOCT) system (Bioptigen, Inc. Durham, NC). Imaging parameters were determined. Ocular tissues were examined with the miniature OCT probe. A miniature SDOCT probe was developed with the scanning driver within the hand piece. The SDOCT fiber-scanning probe maximally transmitted power of 800 μW. The scanning range was 3 mm when the probe tip was held 3 to 5 mm from the tissue surface. The axial resolution was 6 μm and the lateral resolution was 30-35 μm. The 25-gauge forward-imaging probe was used to image cellophane tape, eyelid skin, cornea, conjunctiva, sclera, iris, anterior lens, anterior chamber angle, retina, retinal tear, retinal detachment, optic nerve head, and optic nerve sheath. Images obtained from the miniature probe appeared similar to images from a 3 mm scanning range of a commercial large handheld OCT probe (Bioptigen, Inc. Durham, NC).
