BACKGROUND: Rhegmatogenous retinal detachment (RRD) is a serious condition that occurs when the retina detaches from its underlying retinal pigment epithelium. RRDs associated with giant retinal tears (GRTs) are caused by retinal tears at least 90° or one-quarter of the circumferential extent. This scoping review systematically identifies and summarizes clinical studies evaluating surgical techniques for the management of GRT-related RRDs, discusses functional and visual outcomes and the risk factors affecting treatment outcomes.
METHODS: This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, Scopus, Google Scholar, and Springer Link databases were searched for relevant papers (from January 2001 to March 2023). Studies that were published in the English language and reported the risk factors, management, and treatment outcomes of GRT-related RRDs were included in the review. The outcome measures included anatomic success rates, changes in BCVA (logMAR) from baseline to the final follow-up, and adverse events.
RESULTS: A total of 11,982 articles were identified. After the title and abstract review, 71 studies were deemed eligible for full-text review. Thirty-six studies that met the eligibility criteria were included in the final review. Four surgical techniques were identified: pars plana vitrectomy (PPV), combined PPV and scleral buckling, scleral buckling alone, and pneumatic retinopexy. Various types of tamponades, including gas, silicone oil, and air, have been used. PPV was the most commonly used surgical technique in 33.1-100% of patients. Among the 20 studies that used PPV alone, 17 were associated with preoperative PVR. In addition, scleral buckling alone or in combination with PPV was reported as a treatment option in 10 studies, with 2-100% of patients experiencing scleral buckling alone and 13.6-100% experiencing combined PPV and complementary scleral buckling. Primary anatomic success (PAS) was achieved with retinal reattachment via a single operation with no residual tamponade, whereas final anatomic success (FAS) was achieved via more than one operation with no residual tamponade. Reported single surgery anatomic success (SSAS) rates range from 65.51 to 100%. The preoperative best-corrected visual acuity (BCVA) ranged from 0.067 to 2.47 logMAR, whereas the postoperative BCVA ranged from 0.08 to 2.3 logMAR. An improvement in visual acuity was observed in 29 studies. Cataracts (3.9-28.3%) were the most common postoperative complication, followed by high IOP (0.01-51.2%) and PVR (0.8-31.57%).
CONCLUSIONS: PPV is the most common surgical technique, and currently microincision vitrectomy surgery (MIVS) systems are commonly employed. Silicone oil is the most frequently used tamponade in RRD repair. Risk factors for GRT-related RRD include age, sex, lens status, high myopia status, proliferative vitreoretinopathy (PVR), presenting visual acuity, the extent of the GRT and retinal detachment, and macular involvement. Future research areas include guidelines to reduce variability in the reporting of surgical methodology, choice of tamponades, and reporting of functional and visual outcomes to inform the best therapeutic interventions in GRT-related RRD.

OBJECTIVE: We describe the history and series results of pneumatic retinopexy (PnR)and provide an analysis of PnR utilization after publication of results of pneumatic retinopexy versus vitrectomy for the management of primary rhegmatogenous retinal detachment outcomes randomized trial (PIVOT).
RESULTS: No significant trends were found for average number of services ( P  = 0.153) of PnR after the publication of PIVOT results.
CONCLUSIONS: PnR is a rhegmatogenous retinal detachment (RRD) repair technique that was first described in the early 1900 s and has evolved over time to become a modern-day, minimally invasive, underutilized treatment option. Other repair techniques for RRD include scleral buckling and pars plana vitrectomy (PPV), which has been compared to the use of PnR in PIVOT. Results of PIVOT concluded that PnR offered superior visual acuity and noninferiority. PnR is underutilized in the United States even after publication of results of PIVOT deemed it a noninferior treatment. Lack of a significant increase in national utilization of PnR could be associated with multifactorial clinician, systems, and financial reasons in the real-world setting.

UNASSIGNED: To investigate the incidence and factors influencing the occurrence of metamorphopsia in patients with simple rhegmatogenous retinal detachment (RRD) after surgery.
UNASSIGNED: Relevant studies of metamorphopsia were identified by searching in PubMed, Embase, and Cochrane until August 2022. Meta-analysis of the incidence of metamorphopsia after rhegmatogenous retinal detachment surgery was performed using Review Manager 5.4 statistical software.
UNASSIGNED: A total of 12 studies reported 1133 participants with 469 patients with postoperative metamorphopsia. The meta-analysis showed a higher incidence of metamorphopsia in macular-off cases compared with macular-on RRD (RR = 2.88, 95% CI: 2.35 to 3.52). The use of perfluorocarbon liquid (PFCL) during pars plana vitrectomy (PPV) reduced the incidence of metamorphopsia (RR = 0.61, 95% CI: 0.41 to 0.92). There was no evidence of any important difference in metamorphopsia between participants in the PPV group and the scleral buckling (SB) group (RR = 1.04, 95% CI: 0.82 to 1.33). There was little or no difference in metamorphopsia between gas and silicon oil (SO) in the PPV group (RR = 0.89, 95% CI: 0.69 to 1.13).
UNASSIGNED: The incidence of postoperative metamorphopsia is higher in macular-off RRD, and PFCL should be a preferred choice to prevent postoperative metamorphopsia in macula-off RRD cases.

The treatment of retinal detachment (RD) has seen numerous advancements in the last decades. Scleral buckling (SB) is a surgical procedure introduced in the 1950s that has seen a drastic reduction with the advent of vitrectomy. However, due to the new surgical visualization systems, SB has evolved and continues to be an extremely useful procedure in certain conditions. The presence of different case reports or interventional studies with comparable outcomes, as well as the lack of recent studies with direct comparison, may result in an underestimation of its potential nowadays. The aim of this review is to provide a comprehensive update on chandelier-assisted scleral bucking (CSB), with an overview of the surgical evolution, outcomes, advantages, and complications.

Retinotomy refers to \"cutting\" or \"incising\" the retina, whereas retinectomy denotes \"excising\" the retina. Retinotomies and retinectomies aid in tackling traction and retinal shortening that persist following membrane dissection and scleral buckling. We performed a literature search using Google Scholar and PubMed, followed by a review of the references procured. All relevant literature was studied in detail and summarized. We discuss the indications of retinotomies and retinectomies for relaxing retinal stiffness, accessing the subretinal space for choroidal neovascular membrane, hemorrhage and abscess clearance, drainage retinotomies to allow retinal flattening, radial retinotomies to release circumferential traction, harvesting free retinal grafts, and prophylactic chorioretinectomies in trauma.

OBJECTIVE: This study aims to compare the outcomes of pneumatic retinopexy (PnR) versus pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD).
METHODS: A systematic review and meta-analysis were performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guidelines. An electronic search was conducted identifying six comparative studies of PnR versus PPV for RRD enrolling 1,061 patients. The primary outcome was visual acuity (VA). Anatomical success and complications were the secondary outcomes.
RESULTS: No statistically significant difference was observed in VA between the groups. There was a statistically significant difference in the odds of re-attachment favoring PPV over PnR (odds ratio [OR] = 0.29, P < 0.00001). No statistically significant difference was found in final anatomical success (OR = 1.00, P = 1.00) and the development of cataracts (OR = 0.34, P = 0.61). Other complications, including retinal tears and postoperative proliferative vitreoretinopathy, were more frequently reported in the PnR group.
CONCLUSIONS: PPV has a higher rate of primary reattachment compared to PnR for treating RRD with comparable final anatomical success, complications, and VA outcomes. [Ophthalmic Surg Lasers Imaging Retina 2023;54:354-361.].

To review the literature on eyes with concurrent rhegmatogenous retinal and choroidal detachment (RRD-CD).
Several databases were searched for \"rhegmatogenous retinal detachment\" and \"choroidal detachment\" through October 2022. All English language primary literature was reviewed.
Studies demonstrated that eyes with RRD-CD were very uncommon and had diminished baseline visual acuity (VA) and intraocular pressure (IOP) compared with eyes with RRD only. Although no randomized trials have been performed, pars plana vitrectomy with or without scleral buckle (SB) have reported higher surgical success rates than SB alone. Reattachment rates were affected by age, IOP, adjuvant steroids, and grade of proliferative vitreoretinopathy.
Low IOP and poor initial VA are salient features of eyes with RRD-CD. Steroids can be useful adjuvants administered safely using several routes including periocular and intravitreal injection. PPV ± SB may result in best surgical outcomes.

Rhegmatogenous retinal detachment (RRD) is a serious surgical condition with significant ocular morbidity if not managed properly. Once untreatable, approaches to the repair of RRD have greatly evolved over the years, leading to outstanding primary surgical success rates. The management of RRD is often a topic of great debate. Scleral buckling, vitrectomy and pneumatic retinopexy have been used successfully for the treatment of RRD. Several factors may affect surgical success and dictate a surgeon\'s preference for the technique employed. In this review, we provide an overview and supporting literature on the options for RRD repair and their respective preoperative and postoperative considerations in order to guide surgical management.

OBJECTIVE: We report use of cyanoacrylate (N-butyl-Cyanoacrylate) in previously failed retinal reattachment surgeries for chorio-retinal colobomas. We report the surgical technique, its challenges, and long-term outcomes in three patients who underwent the surgery.
METHODS: A chart review of patients with chorio-retinal colobomas and retinal detachment repair with cyanoacrylate at a tertiary eye care center in Nepal. Cyanoacrylate was used to seal colobomatous retinal breaks in eyes which had undergone multiple retinal surgeries with failed outcome.
RESULTS: Three eyes that were operated using cyanoacrylate were included. All three patients had attached retina and none of the patients required a long-term tamponading agent. None of the patients underwent head positioning following the surgery. All of the patients had a visual acuity gain of 3/60 or more at the end of 8 months. No adverse or inflammatory reactions were noted.
CONCLUSIONS: We demonstrate that cyanoacrylate is safe and less resource-demanding without a requirement of second surgery to remove a tamponading agent. It could be helpful in eyes with persistent retinal detachment in colobomatous eyes. Because we were able to achieve favorable outcomes without head positioning, we believe it may also be helpful in patients who are not suitable for positioning because of bodily or bony deformities and in retinal detachment with other coexisting trauma.

OBJECTIVE: To compare the visual, refractive, and anatomical outcomes and incidence of complications between combined pars plana vitrectomy and phacoemulsification (phacovitrectomy) versus pars plana vitrectomy (PPV-only) in phakic eyes with rhegmatogenous retinal detachment (RRD).
METHODS: Two independent reviewers searched MEDLINE, Cochrane Central, and Web of Science to identify relevant articles. Prospective or retrospective studies comparing PPV-only and phacovitrectomy for RRD were included. Recruited studies provided information about at least anatomical success or refractive outcomes. Meta-analysis was performed for single surgery success rate, final best-corrected visual acuity (BCVA), postoperative complications, mean predicted refractive error, and mean absolute predicted refractive error.
RESULTS: Seven studies (788 eyes) were selected, including two clinical trials and five retrospective comparative case series. The single surgery success rate was similar in PPV-only and phacovitrectomy groups (risk ratio [RR] = 1.02; 95% confidence interval [CI] 0.95-1.10; P = 0.57). Mean final BCVA was significantly better in the PPV-only group than the phacovitrectomy group (MD = 0.06; 95% CI 0.00-0.12; P = 0.04). The risk of epiretinal membrane formation was significantly higher in eyes that underwent phacovitrectomy than PPV-only (RR = 2.85; 0.95% CI 1.5-5.41; P = 0.001). Phacovitrectomy group showed a more myopic final mean predicted refractive error than PPV-only group (MD = -0.31; 95% CI -0.55--0.07; P = 0.01).
CONCLUSIONS: There was no significant difference between the two groups regarding the anatomical outcome. Slightly better visual and refractive results were observed in the PPV-only group. However, the results should be interpreted with caution as the majority of included studies were low-quality retrospective studies.
