超声生物显微镜在前段玻璃体视网膜疾病诊断中的应用

Application of Ultrasound Biomicroscopy in Diagnosis of Anterior Segment Vitreoretinal Disorders

目的:探讨超声生物显微镜(biomicroscopy,UBM)诊断前段玻璃体视网膜疾病。方法:用UBM检查58例60只眼,并与临床检查、B型超声波检查及手术中观察结合起来,综合评价UBM单项检查的客观性。结果:UBM能良好地显示从角膜到赤道部的眼前段结构,发现视网膜脱离42例43只眼、视网膜环形收缩29例29只眼、视网膜前移位24例24只眼、玻璃体混浊或机化55例57只眼、睫状体或脉络膜脱离26例26只眼、睫状体上皮脱离5例6只眼、巩膜穿刺孔处增殖9例9只眼、视网膜肿瘤2例2只眼、睫状体囊肿5例6只眼、硅油周增殖8例8只眼和硅油乳化7例7只眼、玻璃体异物2例2只眼。结论:UBM可用于前段玻璃体视网膜疾病的诊断和鉴别诊断,并对治疗起指导作用。眼科学报1997;13:192—196。

Purpose :To investigate the diagnostic value of ultrasound biomicroscopy(UBM) in anterior segment vitreoretinal disorders( ASVD). Methods: 60 eyes of 58 sequential patients were examined with UBM. The ultrasound biomicroscopic images were compared with the results of clinic examination, B - scan ultra-sonography and the finding during surgery to evaluate the reliability of UBM for ASVD. Results :UBM allows structural details of the conjunctiva, rectus muscle, sclera, uvea, retina and vitreous to be visualized at microscopic resolution in living eye. The area of UBM may cover from cornea to vitreous base, partially to the equator of eye. A variety of the changes of ASVD were imaged in 60 eyes, including retinal detachment in 43 eyes, retinal circumferential contraction in 29 eyes, retinal anterior displacement in 24 eyes, vitreous opacities or fi-brosis in 57 eyes, ciliary orchoroidal detachment in 26 eyes, ciliary nonpigmented epithelial detachment in 6 eyes, proliferative tissue at the sclerotomy site in 9 eyes, retinal neoplasm in 2 eyes, ciliary cyst in 6 eyes, proliferation of peripheral silicone oil in 8 eyes, silicone oil emulsification in 7 eyes and vitreous foreign body in 2 eyes, respectively. Conclusions :Our studies showed the feasibility of UBM for ASVD not visible by current techniques UBM can be used for the diagnosis, differential diagnosis and the instructive treatments of ASVD.
