To compare anterior-segment optical coherence tomography (AS-OCT), ultrasound biomicroscopy (UBM), and direct visualization for detecting vitreous incarceration in sutureless sclerotomies.
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.
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 for identifying incisional vitreous when compared with UBM and AS-OCT (P < .0001). In turn, UBM was superior to AS-OCT for observing vitreous incarceration (P < .0001).
Direct visualization is the most effective method for detecting vitreous entrapment. Regarding the imaging techniques, UBM was superior to AS-OCT for identifying vitreous incarceration.
比较眼前节光学相干断层扫描（AS-OCT）、超声生物显微镜（UBM）以及直接观察法在检测无缝线巩膜切开术中玻璃体嵌顿情况的效果。
在猪眼上进行23G玻璃体切割术的前瞻性、随机、观察者盲法实验研究。通过AS-OCT、UBM以及直接观察法评估术后切口处玻璃体嵌顿情况。
共纳入118只猪眼。分别通过AS-OCT、UBM以及直接观察法分析，发现玻璃体嵌顿在巩膜切开术病例中的占比分别为7.9%（354例中的28例）、59.6%（354例中的211例）和95.5%（354例中的338例）。与UBM和AS-OCT相比，直接观察法是识别切口处玻璃体最敏感的方法（P < .0001）。反过来，在观察玻璃体嵌顿方面，UBM优于AS-OCT（P < .0001）。
直接观察法是检测玻璃体嵌顿最有效的方法。在成像技术方面，UBM在识别玻璃体嵌顿方面优于AS-OCT。
