    Anterior-Segment Optical Coherence Tomography–Guided Measurement Of A Melting Ulcer For Follow-Up Of Corneoscleral Thinning Progression

    Purpose: To evaluate the feasibility of using anterior-segment optical coherence tomography (AS-OCT) for three-dimensional assessment of corneoscleral thinning progression in ulcers after pterygium removal. Methods: A patient with corneoscleral melting after pterygium removal surgery and mitomycin C treatment was evaluated using AS-OCT imaging of the corneoscleral ulcer at five consecutive time points, up to 2 years. AS-OCT scans of 8.3×5.6 mm (15°×10°) containing 41 B-scans spaced 139 μm apart were performed monthly for 4 months and then at 2 years following pterygium removal. A single B-scan was comprised of 768 A-scans. Ten B-scans of the same ...
