摘　　要：目的： 研究眼内占位病变的声像特点、鉴别诊断及其病理基础。方法： 回顾总结３４ 例患者术前的超声图像特点及鉴别要点、其中 ３０ 例术后作了病理检查。结果： 发现病变部位细胞的密度、排列方式及血管和纤维组织的含量和分布状态决定超声的回声强度。结论： 坏死、液化和浆液渗出的部位则出现弱回声或无回声。脉络膜黑色素瘤尾部的大量浆液渗出及坏死、液化是产生 “挖空”现象的原因。Objective:To study the diagnosis and differential diagnosis of intraocular space occupying lesions on pathological basis.Methods:34 patients' ultrasonic imaging characters and differential points of the intraocular lesions were reviewed.30 cases' pathologic findings were compared with that of ultrasonic.Results:The echo intensity is determined by cellular density,arrangment and the conditions of vessel,as well as the fiber tissue content and distributed.Areas necrosis liquefaction and serofluid exudation appeared weak echo or non echo.A large amount serofluid exudation,necrosis and liquefaction in the tail like part of malignant melanoma of choroid constitute “dig hollow” phenomenon.Conclusion:Ultrasonography is useful for diagnosis of intraocular space occupying lesions.
