Ethics committee of the Iran University of Medical Sciences approved the study. In this retrospective non-comparative case series, the charts of all patients with the diagnosis of RRD associated with GRT who underwent surgery from 2005 to 2015 at Rassoul Akram Hospital were reviewed. The aim of this study was to present our experience with the surgery in RRD associated with GRT over 10 years in a tertiary referral hospital. These include, but not limited to wide-angle viewing systems, small gauge vitrectomy instruments, and introduction of perfluorcarbon liquids (PFCL). 7, 8 Also, several innovations in the surgical instrumentations and techniques have improved the success rate of the surgery for GRTs. 2, 3, 4, 5, 6, 7 Several factors including prior vitrectomy, GRT size greater than 180 and the presence of preoperative proliferative vitreoretinopathy (PVR) have reported to be associated with poor surgical success. Final success after single or multiple surgeries has been reported to be between 48 to 100%. 1, 2, 3, 4, 5 These reports are generally small and the surgical techniques are different.
#RETINA DETACHMENT SURGERY SUCCESS RATE SERIES#
6 Few case series have reported outcomes of surgery for RRD associated with GRT. 5 Pars plana vitrectomy (PPV) is the standard treatment for RRD associated with GRT. However, the outcomes were generally poor. Historically, several surgical procedures including intentional retinal incarceration, prone air-fluid exchange and retinal tacks or sutures have been employes for the treatment of rhegmatogenous retinal detachment (RRD) associated with GRT. 1, 2 The majority of GRTs have been described to be idiopathic however, GRT has been reported after trauma, extensive cryotherapy, photocoagulation and refractive surgery. Giant retinal tear (GRT) is defined as a full-thickness circumferential break in the neurosensory retina, extending more than 3 clock hours (90°). Our study shows that the high surgical success can be achieved in patients with RD associated with GRT with single or multiple surgeries. Trauma, extension of tear, age, and lens status had no significant effect on the rate of repeated PPV. The rate of repeated PPV was significantly higher in eyes with PVR at baseline and surgery with encircling episcleral band. Seventeen eyes needed repeated PPV due to redetachment associated with PVR in the follow up period. Anatomic success after one vitrectomy procedure was achieved in 45 eyes (72.58%) and ultimately in 61 eyes (98.4%) at last follow up. An encircling episcleral band was placed in 7 eyes (11.3%).
Pars plana vitrectomy (PPV) alone was performed in 44 eye (71.0%) and simultaneous vitrectomy and phacoemulsification surgery was performed in 18 eyes (29.0%). Proliferative vitreoretinopathy (PVR) was present in 14 (22.6%) of eyes. Sixty two eyes of 61 patients including 51 males and 10 females were assessed. The success rate and factors associated with repeated surgery were determined. All patients had to have at least 3 months of follow up. Exclusion criteria were concomitant presence of diabetic retinopathy, and uveitis. In this retrospective study, the charts of all patients with the diagnosis of RD associated with GRT who underwent surgery from 2005 to 2015 at Rassoul Akram Hospital were reviewed. To present our experience with the surgery in retinal detachment (RD) associated with giant retinal tear (GRT) over 10 years in a tertiary referral hospital.
