HU Zhixiang,LIN Haishuang,YE Lingying, et al. The efficacy of combined vitrectomy-lensectomy and non-combined surgery in the treatment of proliferative diabetic retinopathy[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2020, 50(10): 825-829.
Abstract：Objective: To analyze the effect of combined vitrectomy-lensectomy surgery and non-combined surgery assisted by wide-angle viewing system in the treatment of proliferative diabetic retinopathy (PDR) with cataract. Methods: A retrospective study was conducted in which patients with PDR who underwent vitrectomy assisted by wide-angle viewing system from January 2014 to February 2018. The patients were divided into combined operation group and non-combined operation group according to whether combined lensectomy was used in vitrectomy. The visual acuity changes, total operation time and complications were compared between the two groups. Results: A total of 76 patients (98 eyes) with PDR were enrolled in this study. 57 eyes underwent combined surgery and 41 eyes underwent non-combined surgery. When the preoperative visual acuity was better than finger count, the logMAR visual acuity of the combined operation group improved more than that of the
non-combined operation group (0.6 vs. 0.3, Z=-1.991, P=0.047). Among 39 patients (51 eyes) who were not filled with silicone oil during the initial operation, the total operation time of the combined operation group was shorter than that of the non-combined operation group (Z=-2.368, P=0.018). The common complications of
vitrectomy and silicone oil tamponade in PDR patients were high intraocular pressure and re-bleeding of fundus.Conclusion: For patients with preoperative visual acuity better than finger count, it is recommended to combine phacoemulsification with intraocular lens implantation in PDR vitrectomy to reduce operation time and obtain
better visual acuity.
