Abstract
Purpose :
Retinal detachment (RD) is a serious vision threatening condition. Perfluorocarbon liquid (PFCL) can facilitate RD surgical repair, but endures extra cost and may cause unwanted complications. Endoscopic pars plana vitrectomy (EPPV) bypasses anterior segment opacity but requires the surgeon's hand holding the endoscope to remain stable for visualization compared to microscopic pars plana vitrectomy (MPPV), thus may result in frequent PFCL use during RD repair. The purpose of this study is to compare PFCL use rate between EPPV and MPPV for RD repair.
Methods :
A retrospective chart review of 91 patients who underwent RD repair between August 2017 and July 2023 at a tertiary referral center was conducted. Inclusion criteria involved adult patients with RD repair who had a minimum 6-months post operative follow up visit. Patients' demographics and clinical data collection included visual acuity, intraocular pressure, intraoperative PFCL use, and surgical outcomes. Statistical analysis was performed with independent samples tests of proportion and a p-value of 0.05 was used. This study was approved by our institutional review board.
Results :
Ninety-one patients met the inclusion criteria and were included in this study. The average age of patients was 58.1 ± 16 years (32 were females, 59 were males). There were 91 eyes that underwent RD repair, 44 eyes (48.3%) underwent EPPV and 47 eyes (51.6%) underwent PPV. In the EPPV group, 26 eyes (59%) had PFCL used during surgery (five eyes with rhegmatogenous retinal detachments [RRD], and 21 eyes with tractional retinal detachment [TRD]). In the MPPV group, 15 eyes (32%) had PFCL used during surgery (12 eyes with RRD, and three eyes with TRD). The rate of PFCL use between the EPPV and MPPV groups was statistically different (p=0.017). At one-month postoperative visit, the EPPV and PFCL subgroup had three retinal re-detachments (11.5%), while the MPPV and PFCL subgroup had one retinal re-detachment (6.7%).
Conclusions :
In this study, PFCL use was significantly more frequent in the EPPV group compared to the MPPV group. When PFCL was used, there was no statistically significant difference in the re-detachment rate between both subgroups. PFCL may serve a larger role in EPPV that led to its increased use during RD repair. Prospective larger studies are needed to better evaluate the role of PFCL in EPPV for RD repair.
