![]() ![]() The presence of a gas bubble in an incompletely vitrectomized eye can induce traction on the peripheral retina, leading to formation of peripheral breaks and retinal detachment. ![]() Retinal detachment may be attributable to the surgical technique, and can be affected by how much of the peripheral vitreous remained in MH cases. The incidence of retinal detachment after vitrectomy is 6–8% in epi-retinal membrane (ERM) cases, 6% in branch retinal vein occlusion cases, and varies between 0-11% in macular hole (MH) cases. Retinal detachment is one of the most severe complications following vitrectomy. Intraoperative 360° laser retinopexy following phacovitrectomy resulted in a significant reduction in the rate of postoperative retinal detachment in MH cases. There was no significant difference between the groups in RRD cases (p = 0.092). Kaplan-Meier survival analysis demonstrated that the rate of retinal detachment in the control group was significantly higher than that in the 360° laser group (p = 0.035). ![]() The 360° laser group showed a significant reduction (0%, 0/77 eyes) in the rate of the incidence of retinal detachment after vitrectomy at 12 months after surgery in MH cases, compared with the control group (5.7%, 2/35 eyes) (p = 0.034). Additionally, prophylactic intraoperative 360° laser treatment was performed on 108 RRD cases (64.0 years) and compared to 270 RRD cases (64.4 years). Prophylactic intraoperative 360° laser treatment was performed on 77 MH cases (67.3 years) and compared to a control group of 35 MH cases (65.8 years). The baseline characteristics and the risk of retinal detachment over time were analyzed and compared between the groups. For the 360° laser treatment group, three rows of medium-white burns were positioned anterior to the equator. The patients were part of two consecutive case series cohorts in macular hole (MH) and rhegmatogenous retinal detachment (RRD), one which did not receive intraoperative prophylactic 360° laser, and one which received intraoperative prophylactic 360° laser. To investigate the effect of intraoperative 360° laser retinopexy anterior to the equator for the prevention of retinal detachment after phacovitrectomy. ![]()
