Two-year outcomes of different subretinal fluid drainage techniques during vitrectomy for fovea-off rhegmatogenous retinal detachments: ELLIPSOID-2 study. Br J Ophthalmol 2024; 108:1263-1268. [PMID: 38290803 DOI: 10.1136/bjo-2023-323879] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Accepted: 12/20/2023] [Indexed: 02/01/2024]
Abstract
BACKGROUND The purpose of the study is to compare visual acuity, complications and outer retinal integrity following subretinal fluid (SRF) drainage from the peripheral retinal breaks (PRBs) versus posterior retinotomy (PR) versus perfluorocarbon liquid (PFCL) for macula-off rhegmatogenous retinal detachments (RRDs) at 2 years post-surgery. METHODS Retrospective analysis of 300 consecutive patients with primary RRD undergoing 23-gauge pars plana vitrectomy with SRF drainage through (1) PRB (n=100), (2) PR (n=100) or (3) with PFCL (n=100). Primary outcomes were visual acuity (best-corrected visual acuity (BCVA)) and complications (cystoid macular oedema (CMO) and epiretinal membrane (ERM)). Secondary outcomes were discontinuity of the external limiting membrane (ELM), ellipsoid zone (EZ) and interdigitation zone (IDZ) at 2 years post-surgery. RESULTS Mean (±SD) logMAR BCVA at 24 months was better in the PRB compared with PR and PFCL, with PFCL having the worst BCVA (PRB 0.5±0.6; PR 0.7±0.5; PFCL 0.9±0.7, p=0.001). CMO was higher with PFCL (PRB 29.7%; PR 30.2%; PFCL 45.9%, p=0.0015) and ERM formation was higher in PR (PRB 62.6%; PR 93.0%; PFCL 68.9%, p=0.002). There were no differences in ELM or EZ discontinuity. However, IDZ discontinuity was higher in PFCL (PRB 34%; PR 27%; PFCL 46%, p=0.002) at 2 years. CONCLUSIONS Visual acuity was worse and discontinuity of the IDZ and CMO was greater in eyes with PFCL-assisted drainage compared with PRB or PR. Drainage technique may impact long-term visual acuity and photoreceptor integrity.

Abstract
Purpose Proliferative retinal changes may occur postsurgery for rhegmatogenous retinal detachment (RRD), possibly preceding recurrent detachment. This study aims to establish the groundwork for an imaging system capable of discerning changes in retinal vessel tortuosity after RRD repair, analyzing widefield optical coherence tomography angiography (WF-OCTA) images. Methods Eighty-eight eyes of 86 patients with RRD who underwent surgical procedures and had repeated imaging with clear widefield optical coherence tomography (WF-OCT) and WF-OCTA on different postoperative days were enrolled in this retrospective study. We compared WF-OCTA images over time to identify alterations in retinal vessel tortuosity and observed regional changes in retinal morphology. Results After image processing, changes in retinal vessel tortuosity were detected in 66 quadrants. These changes, attributed to retinal traction from proliferative membranes, were observed in 56 quadrants, among which retinal thickness remained unchanged in seven sectors (12.5%) according to the WF-OCT map. In nine quadrants, changes in retinal vessel tortuosity were attributed to changes in subretinal fluid, aligning with observable variations in retinal thickness. Conclusions Observation of vessel tortuosity changes using WF-OCTA can help detect early postoperative proliferative changes in eyes with RRD. Translational Relevance Because WF-OCTA can detect minute vessel tortuosity changes, it can offer a noninvasive alternative for the detection of early postoperative proliferative changes.

Abstract
PURPOSE To assess efficacy and safety outcomes of subretinal fluid drainage methods during pars plana vitrectomy for rhegmatogenous retinal detachment. METHODS A systematic search strategy was conducted for studies published between January 2000 and October 2022. Included studies reported on either the safety or efficacy of two or more drainage methods during pars plana vitrectomy for patients with rhegmatogenous retinal detachment. RESULTS Two randomized and five observational studies consisting of 1,524 eyes were included. Best-corrected visual acuity at the last study observation and primary reattachment rates were similar across groups. A significantly lower risk of epiretinal membrane formation was associated with draining subretinal fluid through preexisting retinal breaks (risk ratio = 0.70, 95% confidence interval = [0.60, 0.83], P = <0.01, I 2 = 0%) or with perfluorocarbon liquid (risk ratios = 0.70, 95% confidence interval = [0.59, 0.83], P = <0.01, I 2 = 0%) compared with posterior retinotomy. The risk of an abnormal foveal contour was significantly greater in perfluorocarbon liquid-treated eyes relative to posterior retinotomy (risk ratios = 1.56, 95% confidence interval = [1.13, 2.17], P = <0.01, I 2 = 0%). CONCLUSION No significant differences were observed in the final best-corrected visual acuity at the last study observation and primary reattachment rates across different drainage methods. There remains limited information on the topic, so future research is warranted.

Abstract
We investigated the impact of drainage retinotomy on the outcome of pars plana vitrectomy for repair of rhegmatogenous retinal detachment (RRD). This study was a retrospective observational multicenter study. All patients were registered with the Japan-Retinal Detachment Registry. We analyzed 1887 eyes with RRD that had undergone vitrectomy and were observed for 6 months between February 2016 and March 2017. We compared the baseline characteristics and postoperative outcomes between eyes with and without drainage retinectomy. We then performed propensity score matching using preoperative findings as covariates to adjust for relevant confounders. Of 3446 eyes, 1887 met the inclusion criteria. Among them, 559 eyes underwent vitrectomy with drainage retinotomy, and 1328 eyes underwent vitrectomy without drainage retinotomy. After propensity score matching, each group comprised 544 eyes. There was no significant difference between the two groups in BCVA at 6 months after vitrectomy (0.181 vs. 0.166, P = 0.23), the primary anatomical success rate (6.3% vs. 4.4%, P = 0.22), or the rate of secondary surgery for ERM within 6 months (1.5% vs. 1.3%, P = 1.0). Drainage retinectomy does not increase the risk of decreased postoperative BCVA, surgical failure, or secondary surgery for ERM within six months outcomes.

Abstract
BACKGROUND Epiretinal membrane (ERM) causes visual impairment such as reduction in visual acuity and metamorphopsia due to retinal traction. With the improvement of optical coherence tomography (OCT) and microincision vitrectomy surgery (MIVS), the surgery of ERM has significantly advanced. However, there have been no large-scale studies on the following: (1) how to evaluate visual impairment in ERM, (2) the relationship between OCT findings and visual function, (3) when is the optimal timing of surgery, and (4) the relationship between the surgical instruments as well as techniques and prognosis. The purpose of this study was to obtain evidence regarding these ERM surgeries. METHODS AND DESIGN This is a prospective, multicenter cohort study of ERM surgery in Japan from March 1, 2023, to March 31, 2027 (UMIN000048472, R-3468-2). Patients who underwent ERM surgery during the study period and agreed to participate in this study will be included. The goal is to have a total of 5,000 eyes surgically treated for ERM. The following data will be collected: age, gender, medical history, subjective symptoms, visual function before and 6 and 12 months after surgery, clinical findings, OCT data, surgical technique, instruments used in surgery, and complications. DISCUSSION The results of this study will support the surgical decisions and procedures in ERM practices.

Abstract
PURPOSE To investigate the incidence and risk factors for the main complications in patients with rhegmatogenous retinal detachment treated with scleral buckling (SB) or pars plana vitrectomy (PPV). METHODS A retrospective, comparative, observational study was conducted. The medical records of 107 patients with primary rhegmatogenous retinal detachment who were managed with SB (n = 57) or PPV (n = 50) were reviewed. Scleral buckling was performed using scleral encircling solid silicone band and circumferential solid silicone exoplant to support the break. Pars plana vitrectomy was combined with phacoemulsification in phakic eyes and with scleral encircling in inferior detachments. Follow-ups, including spectral-domain optical coherence tomography examination, were scheduled at 1, 3, and 12 months after surgery. Propensity score matching was used to adjust for potential preoperative selection bias. RESULTS The overall incidence of postoperative cystoid macular edema (CME) and epiretinal membrane was 14.95% and 30.84%, respectively. Compared with SB, CME was more frequent in the PPV (P = 0.021) and in the PPV pseudophakic eyes (P = 0.027). Postoperative CME was an early, predominantly transient complication and regressed in 67% of SB and in 77% of PPV eyes within 12 months after surgery. No differences were observed regarding epiretinal membrane development. Except for the surgical technique, no preoperative factors associated with CME were identified. A correlation between epiretinal membrane and patients' age was found (P = 0.028). CONCLUSION The incidence of CME after rhegmatogenous retinal detachment repair was higher in patients who underwent PPV, either alone or combined with phacoemulsification, than in those treated with SB. Epiretinal membrane development was correlated to older age, regardless of the surgical procedure.

Abstract
Background To compare the safety and efficacy of Ab-externo subretinal bands removal in comparison with the classical Ab-interno approach during pars plana vitrectomy for primary rhegmatogenous retinal detachment. Methods Subjects aged 28–62 years with primary RRD complicated by proliferative vitreoretinopathy (PVR) with subretinal bands interfering with retinal flattening were treated by pars plana vitrectomy (PPV) and silicone oil injection. Subretinal bands were removed using the classical AB interno approach through one or more retinotomies in ten patients (group A) and using AB externo approach in twenty cases (group B). Post-operative follow-up visits occurred at 1 day, 1 week, 1 month, and 3 months, after surgery. The main outcomes were assessment of subretinal bands removal efficacy, documentation of complications, anatomical reattachment rate, and postoperative best-corrected visual acuity (BCVA). Results There was no statistically significant difference between both groups regarding patients’ age, gender, lens status, and the onset of retinal detachment. Seventy percent of both groups presented with inferior retinal detachment while ten percent presented with temporal detachments and twenty percent had a total retinal detachment. Both groups had a statistically significant improvement in postoperative visual acuity in comparison with preoperative visual acuity (P = 0.005 for group A and P = < 0.001 for group B). There was no statistically significant difference between both groups regarding preoperative (P = 0.928) and postoperative (P = 0.185) visual acuity. A higher incidence of complications was reported in group A (40%) in comparison with group B (30%) but this difference was not statistically significant (P = 0.69). More Epimacular membranes were seen postoperatively in group A (30%) in comparison with group B (20%) but again this difference was not statistically significant (P = 0.657). Subretinal hemorrhage was seen in ten percent of cases in both groups. Intraocular pressure was measured in every follow-up of all patients in both groups, no statistically significant difference was found between both groups. Conclusions Both techniques are effective and safe to remove subretinal bands with similar outcomes.
