目的：分析20 MHz B超声的声像特征及其诊断价值。方法选取来该院就诊，已明确诊断的眼底疾病患者以20 MHz B超采用直接法对其探查，并将声像图与其OCT检查结果进行对比分析。结果根据OCT检查结果分析相应的20 MHz B超声像特征，黄斑裂孔8眼，B型超声显示黄斑区圆顶带状表浅隆起回声，病变中央呈孔状断裂；中心性浆液性脉络膜视网膜病变17眼，B型超声图像表现为黄斑区形态规则的纤细条索扁平弧形或峰样隆起回声，越远离黄斑中心凹隆起越低；黄斑裂孔性视网膜脱离5眼、黄斑水肿20眼、视网膜劈裂2眼，B型超声均显示黄斑区表面局限性弧形或形态不规则的扁平弧形条索状表浅隆起回声，其下为液性无回声间隙；视网膜色素上皮层（RPE ）脱离3眼，B型超声检查显示后极部表面局限性不规则带状强回声浅隆起，其下见液性无回声间隙。结论在屈光间质混浊及非后极部病变的情况下，20 MHzB超探查对眼底疾病能够进行初步鉴别，一定程度上弥补了OCT不足。

Objective To analyze the application of 20 MHz B-scan ultrasound to the diagnosis of fundus diseases.Methods Patients with posterior fundus diseases underwent 20 MHz B-scan ultrasound detection by direct method.The ultrasonograms were comparatively analyzed with OCT.Results The diagnoses of patients were confirmed by OCT.Ultrasonogram of 8 eyes with macular hole showed the dome-shaped uplift echoes in macular,whose center was rupture.Ultrasonogram of 17 eyes with central serous chorioretinopathy showed regular arc or peak-shaped echoes.Ultrasonogram of 5 eyes with macular hole retinal detachment,20 eyes with macular edema and 2 eyes with retinoschisis showed local arc-shaped or unregular ribbon-shaped echoes,and under which there was no-echo gap.Ultrasono-gram of 3 eyes with retinal pigment epithelium detachment showed unregular local ribbon-shaped echoes,and under which there was no-echo gap.Conclusions In the cases with ocular media opacity or non-posterior fundus diseases,20 MHz B-scan ultrasound could dif-ferentiate the disease preliminarily,which could make up the limitation of OCT.
