Current status and progress of surgical management of giant retinal tear / 眼科新进展

ABSTRACT

Giant retinal tear (GRT) refers to a retinal break extending circumferential for ≥ 3 clock hours (＞90°) of the retinal with trailing edge folding.With the de velopment of technology,success rate of surgical for GRT was increased.Chandelier illumination can help surgeons complete the operation by themselves,and 23 G,25G,27G microsurgical techniques make it easy for the application of surgical instruments and amplify the scope of operation.Meanwhile,endoscope can reduce the impact of refractive media opacity.Administration of preoperative intraocular medicine is helpful for the operation.However,there is no definite findings of whether adjuvant scleral buckling and lens extraction are necessary in the management of GRT as well as how to deal with retinal stiff and flap of GRT.And this article tries to summarize the pathogenesis,surgical methods and pre-and post-operative stuffing of the GRT.
