To describe a new surgical technique to effectively close large (>180 degrees) cyclodialysis clefts.
Our method involves the use of procedures commonly associated with repair of retinal detachment and complex cataract extraction: phacoemulsification with placement of a capsular tension ring followed by pars plana vitrectomy and gas tamponade with light cryotherapy. We also used anterior segment optical coherence tomography (OCT) as a noninvasive mechanism to determine the extent of the clefts and compared those results with ultrasound biomicroscopy (UBM) and gonioscopy.
This technique was used to repair large cyclodialysis clefts in 4 eyes. All 4 eyes had resolution of hypotony and improvement of visual acuity. One patient had an intraocular pressure spike requiring further surgical intervention. Anterior segment OCT imaging in all 4 patients showed a more extensive cleft than UBM or gonioscopy.
This technique is effective in repairing large cyclodialysis clefts. Anterior segment OCT more accurately predicted the extent of each cleft, while UBM and gonioscopy both underestimated the size of the cleft.
描述一种有效闭合大（>180度）睫状体分离裂隙的新手术技术。
我们的方法包括使用通常与视网膜脱离修复和复杂白内障摘除相关的手术步骤：超声乳化并植入囊袋张力环，随后进行玻璃体平坦部玻璃体切除术和光凝冷冻疗法下的气体填充。我们还使用眼前段光学相干断层扫描（OCT）作为一种非侵入性手段来确定裂隙范围，并将这些结果与超声生物显微镜检查（UBM）和前房角镜检查结果进行比较。
该技术用于修复4只眼中的大睫状体分离裂隙。所有4只眼的低眼压均得到缓解，视力有所提高。1例患者眼压急剧升高，需要进一步手术干预。所有4例患者的眼前段OCT成像显示裂隙范围比UBM或前房角镜检查显示的更广泛。
该技术在修复大睫状体分离裂隙方面有效。眼前段OCT能更准确地预测每个裂隙的范围，而UBM和前房角镜检查均低估了裂隙大小。
