UBM在原发性闭角型青光眼手术前后的应用

Application of UBM in the pre- and post-operative management of primary angle-closure glaucoma

手术是原发性闭角型青光眼（primary angle-closure glaucoma，PACG）治疗的有效手段。超声生物显微镜检查（ultrasound biomicroscopy，UBM）可实现对房角等眼前段各种组织的形态学观察和定量测量，从而在手术前有利于明确PACG的发病机制，如单纯性瞳孔阻滞型和非瞳孔阻滞型及多种机制并存型等；手术后可通过UBM观察虹膜周边切除孔、滤过泡的形态及可能出现的睫状体脱离、脉络膜脱离、迟发性脉络膜上腔出血等术后并发症，从而指导治疗及随访。

The effective treatment of primary angle-closure glaucoma （PACG） is surgery. The anterior segments of the eye can be analyzed and quantitatively measured with the ultrasound biomicroscope （UBM）. Thus, the pathogenesis of PACG can be evaluated precisely, such as pupillary block angle-closure glaucoma, non-pupillary angle block glaucoma or combined mechanisms. After surgery, the peripheral iridectomy, the shape of the filtering bleb as well as the postoperative complications such as ciliary body detachment, choroidal detachment and delayed suprachoroidal hemorrhage, can be also observed with UBM.
