Assessment of Vitreous Incarceration in Sclerotomies With OCT, Ultrasound Biomicroscopy, and Direct Visualization
BACKGROUND AND OBJECTIVE: To compare anterior-segment optical coherence tomography (AS-OCT), ultrasound biomicroscopy (UBM), and direct visualization for detecting vitreous incarceration in sutureless sclerotomies. MATERIALS AND METHODS: Prospective, randomized, and observer-masked experimental study in which 23-gauge vitrectomy was performed in pig eyes. Postoperative incisional vitreous incarceration was evaluated by AS-OCT, UBM, and direct visualization. RESULTS: One hundred eighteen pig eyes were included. Vitreous entrapment was found in 7.9% (28 of 354), 59.6% (211 of 354), and 95.5% (338 of 354) of the sclerotomies analyzed by AS-OCT, UBM, and direct visualization, respectively. Direct visualization was the most sensible method ...
