(1) Background: Ocular emergencies account for 1.5-3% of emergency department (ED) visits and require urgent diagnosis to prevent serious complications. Ultrasonography is a crucial, non-invasive diagnostic tool for these conditions but traditionally lacks portability and integration with modern electronic smart devices. The purpose of this study was to assess the accuracy and performance of a new handheld ultrasound device in comparison to a conventional cart-based sonographic machine in patients attending to the ED for vitreo-retinal diseases. (2) Methods: three specialists in ophthalmology, with at least 4-year experience in vitreo-retinal diseases and eye ultrasound, evaluated images of 50 eyes with both portable and traditional ultrasound probes. Each specialist made the diagnosis based on the images captured with both probes and then rated their overall image quality and confidence of diagnosis with a five-point Likert scale. The concordance of diagnosis between the two probes was evaluated. (3) Results: The sample comprised 42 patients. Twenty (40%) healthy eyes and thirty eyes with the following vitreo-retinal interface conditions were examined: 12 retinal detachment (24%), 8 vitreous hemorrhage (16%), and 10 posterior vitreous detachment (20%). The overall accuracy of the two devices appeared to be comparable (70.7% vs. 69.3%). The Butterfly iQ+ probe showed similar sensitivity in retinal detachment diagnosis (91.7% vs. 94.4% of the Accutome B-scan Pro), while it showed poor performance in diagnosing posterior vitreous detachment (sensitivity = 27.2%); (4) Conclusions: The Butterfly iQ+ device demonstrated high sensitivity in the diagnosis of retinal detachment. Significant adjustments are still needed to improve the resolution of the vitreous body.
(1) 背景：眼科急症占急诊科就诊病例的1.5 - 3%，需要紧急诊断以预防严重并发症。超声检查是诊断这些病症的关键非侵入性工具，但传统上缺乏便携性且无法与现代电子智能设备集成。本研究的目的是评估一种新型手持式超声设备与传统台式超声诊断仪相比，在急诊科就诊的玻璃体视网膜疾病患者中的准确性和性能。(2) 方法：三位眼科专家，在玻璃体视网膜疾病和眼部超声方面至少有4年经验，使用便携式和传统超声探头评估了50只眼睛的图像。每位专家根据两种探头采集的图像进行诊断，然后用五点李克特量表对整体图像质量和诊断信心进行评分。评估两种探头诊断结果的一致性。(3) 结果：样本包括42名患者。检查了20只（40%）健康眼睛和30只患有以下玻璃体视网膜界面病症的眼睛：12只视网膜脱离（24%）、8只玻璃体出血（16%）和10只玻璃体后脱离（20%）。两种设备的总体准确率似乎相当（70.7%对69.3%）。Butterfly iQ +探头在视网膜脱离诊断中显示出相似的敏感性（与Accutome B扫描探头相比为91.7%对94.4%），而在诊断玻璃体后脱离方面表现不佳（敏感性 = 27.2%）；(4) 结论：Butterfly iQ +设备在视网膜脱离诊断中显示出高敏感性。仍需要进行重大调整以提高玻璃体的分辨率。
