虹膜劈裂1例

A case of iridoshcisis

患者因"左眼视物模糊20余年"就诊,20余年前曾行左眼小梁切除术,视力:右眼(oculus dex ter,OD)无光感(nolightperception,NLP),左眼(oculussinister,OS)光感(lightperception,LP)光定位准确,右眼巩膜葡萄肿(鼻上),前房浅约1/4CT,瞳孔固定散大,晶状体脱位于玻璃体腔,左眼结膜上方滤过泡扁平,前房浅,约1/4 CT,虹膜层状分离漂浮于前房,上方虹膜切口引流通畅,C/D:0.4。眼压(intraocular pressure,IOP)示:右眼13.0 mm Hg,左眼16.0 mm Hg。超声生物显微镜(ultrasound biomicroscopy,UBM)示:右眼各象限前房角狭窄,晶体脱位;左眼前房浅,颞侧前房角狭窄,其余象限关闭,虹膜层状分离。B超示:右眼晶体脱离。诊断:左眼虹膜劈裂;右眼晶体脱位。

The patient was treated with‘left eye blurred vision for more than 20 years’.The patient underwent left trabeculectomy more than 20 years ago.Visual acuity oculus dexter(OD):no light perception(NLP),oculus sinister(OS):light perception(LP),and light positioning was accurate,right eye scleral staphyloma(nose),the anterior chamber was approximately 1/4 CT,the pupil was fixed and scattered,the lens was displaced into the vitreous cavity,and the left eye conjunctiva was filtered.The blister was flat,the anterior chamber was shallow,about 1/4 CT,and the iris layer was separated and floated in the anterior chamber.The upper iris incision led to smooth flow,C/D:0.4.Intraocular pressure(IOP):R 13.0 mmHg,L 16.0 mmHg.Ultrasound biomicroscopy(UBM):in the right eye,anterior chamber angle was narrow in each quadrant,dislocation of the lens;anterior chamber of the left eye was shallow,anterior chamber angle of the temporal stenosis was narrow,the remaining quadrants were closed,iris lamellar separated.B-ultrasound:the right eye lens was displaced into the vitreous cavity.Diagnosis:left eye Iridoshcisis;right eye lens dislocation.
