ABSTRACT
Objective To observe the retinal reattachment of suprachoroidal injection with sodium hyaluronate in the treatment of rhegmatogenous retinal detachment (RRD).Methods Twelve eyes of 12 patients with RRD diagnosed by the examinations of B-mode ultrasound,binocular indirect ophthalmoscope,OCT and scanning laser ophthalmoscope in West China Hospital of Sichuan University from October 2018 to February 2019 were included in this study.There were 7 males and 5 females,aged from 15 to 66 years,with the mean age of 32.40± 14.81 years.There were 4 eyes with BCVA＜0.1,4 eyes with BCVA 0.1-0.4,4 eyes with BCVA＞0.4.The extent of retinal detachment involves 1 to 4 quadrants.All eyes were injected with sodium hyaluronate via suprachoroidal space under non-contact wide-angle system.Surgery was performed by the same ophthalmologist with extensive surgical experience.During the operation,the retinal hole was handled with scleral freezing and laser photocoagulation.The follow-up was 2 months.The retinal reattachment was observed.Results Of the 12 eyes,6 eyes (50.00％) were anatomically reattached,4 eyes (33.33％) ere partly anatomically reattached with subretinal fluid,2 eyes (16.67％) were not reattached.The holes in 4 eyes of partly anatomically reattached with subretinal fluid were located on the choroidal pad and the holes were closed,in addition,the subretinal fluid gradually absorbed over time.Two eyes failed in retinal reattachment received vitrectomy with silicone oil tamponade or sclera buckling surgery.No severe complications such as endophthalmitis and choroidal hemorrhage were found at follow-up visits.Conclusion Suprachoroidal injection of sodium hyaluronate is an effective and safe treatment for RRD,which can promote retinal reattachment.
