METHODS: From April 2015 to April 2017, 20 patients(20 eyes)with coexisting rhegmatogenous retinal detachment and choroidal detachment who were treated in Department of Ophthalmology, Jiangsu Province Hospital were enrolled in this retrospective analysis. All patients received modified scleral puncture drainage combined with 23G minimally invasive vitrectomy. This study analyzed and compared intraoperative paracentesis success rate, the incidence of intraoperative, postoperative visual acuity, intraocular pressure, and postoperative retinal reattachment rate.

RESULTS: Suprachoroidal fluid from all patients were drainaged successfully. Compared with preoperative conditions, the postoperative visual acuity was significantly improved(P<0.01). There was a significant difference in average intraocular pressure(IOP)between preoperative one and postoperative one(7.00±2.05mmHg and 15.38±2.66mmHg respectively, P<0.01). The origin retinal reattachment rate was 90%(18/20), and the final retinal reattachment rate was 95%(19/20).

CONCLUSION: The modified scleral puncture surgery in the treatment of patients with coexisting rhegmatogenous retinal detachment and choroidal detachment in 23G vitrectomy has great clinical effects. It not only simplifies the procedure of operation, but also reduces the difficulty and complication of operation.
