Abstract
Purpose :
To analyze the data collected by the Japanese Retina and Vitreous Society (JRVS) registry system on the treatment of eyes with rhegmatogenous retinal detachment (RRD). The registration is conducted by the JRVS which consists of retinal specialists at the ophthalmological institutions throughout Japan.
Methods :
The JRVS registry is a nonrandomized, prospective data collection aimed at analyzing the surgical outcomes of the treatments for RRD. A total of 26 institutions, comprising the JRVS committee members, were selected as data-collecting hospitals. All RRD cases treated at these hospitals were registered by the surgeons to the central data center using a web-based system between February 2016 and May 2017. A questionnaire consisting of 61 questions was completed for each case. The 3-month follow-up data were analyzed.
Results :
The 3-month follow-up data of 2648 cases were registered by November 2017. The primary surgery performed on these cases was pals plana vitrectomy (PPV) in 1833 eyes (69.2%), scleral buckle (SB) in 625 eyes (23.6%), and PPV combined with SB (PPV+SB) in 190 eyes (7.2%). The reoperation rate was 5.4%, 6.4%, and 9.5% after PPV, SB, and PPV+SB, respectively. The reoperation rate was higher after PPV+SB than that after PPV (P=0.032, Fisher’s exact test). The incidence of reoperation was 4.0%, 5.9%, 7.4% in phakic patients, and 9.8%, 11.1% and 13.7% respectively in pseudophakic patients. In eyes with proliferative vitreoretinopathy (PVR), the rate of reoperation was dependent on the grade of the PVR: 0-A, 5.4%; grade B, 7.7%; and grade C, 14.6% (P=0.001, Chi-square test).
Conclusions :
The analyses of the JRVS registry data showed that PPV was the most frequently performed primary surgery for RRD in Japan. A second surgery was required more often in pseudophakic than phakic eyes. The rate of reoperation is dependent on the grade of the PVR. The JRVS registry system is promising in terms of the critical analyses of real-world treatments for RRD and in improving the treatment strategy for RRD cases.
