探讨高频线阵探头对眼球壁的观察，并对引起球壁回声增厚的疾病及其超声表现进行分析。

这是一项回顾性横断面研究。回顾分析2023年9月至2023年10月于首都医科大学附属北京同仁医院眼科中心行眼部彩色多普勒超声检查的患者的超声图像。所有患者均采用线阵探头采集图像，探头频率为4~20 MHz。观察正常眼球壁的声学表现。对于表现为球壁回声增厚的患者，结合临床诊断统计病因，并对其超声表现进行分析。

共纳入10 340例患者，正常眼球壁在超声表现为强回声，层间结构（视网膜、脉络膜、巩膜）不易分辨。球壁回声增厚患者139例（160只眼），其中低眼压相关疾病所致（包括眼外伤、视网膜脱离、手术后低眼压、陈旧眼部病变）106例（109只眼）、小眼球10例（20只眼）、葡萄膜炎6例（10只眼）、后巩膜炎6例（7只眼）、眼内炎5例（5只眼）、弥漫性脉络膜血管瘤4例（7只眼）、脉络膜转移癌1例（1只眼）、葡萄膜淋巴瘤1例（1只眼）。球壁回声增厚时球壁的层间结构可部分被分辨。

高频线阵探头对眼球壁的观察具有重要价值。球壁回声的增厚多见于累及脉络膜、巩膜及巩膜外Tenon's囊的疾病。结合不同超声表现可对引起球壁回声增厚的疾病进行鉴别。

To observe the eyeball wall using a high-frequency linear array probe, and to analyze different ultrasound manifestations of eyeball wall thickening.

This was a retrospective cross-sectional study in which eye color Doppler ultrasonography images obtained from September to October 2023 in Beijing Tongren Hospital were retrospectively analyzed. All images were obtained using a linear array probe, and the probe frequency was 4 to 20 MHz. The ultrasound manifestations of the eyeball wall were investigated. The ultrasound features of eyeball wall thickening were analyzed in combination with clinical diagnosis.

The imaging data of 10340 patients were included in this study. The normal eyeball wall showed strong echo on ultrasound, and the interlayer structures (the retina, choroid, and sclera) were difficult to distinguish. There were 139 patients (160 eyes) with thickened eyeball wall echo. Diseases that cause thickening of eyeball wall echo included diseases related to low intraocular pressure (such as ocular trauma, retinal detachment, postoperative low intraocular pressure, and old eye diseases) in 106 patients (109 eyes), microphthalmia in 10 (20 eyes), uveitis in 6 (10 eyes), posterior scleritis in 6 (7 eyes), endophthalmitis in 5 (5 eyes), diffuse choroidal hemangioma in 4 (7 eyes), choroidal metastasis in 1 (1 eye), and uveal lymphoma in 1 (1 eye). When there was echo showing that the eyeball wall thickened, the interlayer wall structure could be partially distinguished.

High-frequency linear array probe can be used to observe the eyeball wall. Thickening of the eyeball wall is more common in diseases involving the choroid, sclera, and Tenon's capsule. These diseases can be differentially diagnosed by combining different ultrasound manifestations.
