Performance of Automated Machine Learning in Predicting Outcomes of Pneumatic Retinopexy. OPHTHALMOLOGY SCIENCE 2024; 4:100470. [PMID: 38827487 PMCID: PMC11141253 DOI: 10.1016/j.xops.2024.100470] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 12/30/2023] [Accepted: 01/12/2024] [Indexed: 06/04/2024]
Abstract
Purpose Automated machine learning (AutoML) has emerged as a novel tool for medical professionals lacking coding experience, enabling them to develop predictive models for treatment outcomes. This study evaluated the performance of AutoML tools in developing models predicting the success of pneumatic retinopexy (PR) in treatment of rhegmatogenous retinal detachment (RRD). These models were then compared with custom models created by machine learning (ML) experts. Design Retrospective multicenter study. Participants Five hundred and thirty nine consecutive patients with primary RRD that underwent PR by a vitreoretinal fellow at 6 training hospitals between 2002 and 2022. Methods We used 2 AutoML platforms: MATLAB Classification Learner and Google Cloud AutoML. Additional models were developed by computer scientists. We included patient demographics and baseline characteristics, including lens and macula status, RRD size, number and location of breaks, presence of vitreous hemorrhage and lattice degeneration, and physicians' experience. The dataset was split into a training (n = 483) and test set (n = 56). The training set, with a 2:1 success-to-failure ratio, was used to train the MATLAB models. Because Google Cloud AutoML requires a minimum of 1000 samples, the training set was tripled to create a new set with 1449 datapoints. Additionally, balanced datasets with a 1:1 success-to-failure ratio were created using Python. Main Outcome Measures Single-procedure anatomic success rate, as predicted by the ML models. F2 scores and area under the receiver operating curve (AUROC) were used as primary metrics to compare models. Results The best performing AutoML model (F2 score: 0.85; AUROC: 0.90; MATLAB), showed comparable performance to the custom model (0.92, 0.86) when trained on the balanced datasets. However, training the AutoML model with imbalanced data yielded misleadingly high AUROC (0.81) despite low F2-score (0.2) and sensitivity (0.17). Conclusions We demonstrated the feasibility of using AutoML as an accessible tool for medical professionals to develop models from clinical data. Such models can ultimately aid in the clinical decision-making, contributing to better patient outcomes. However, outcomes can be misleading or unreliable if used naively. Limitations exist, particularly if datasets contain missing variables or are highly imbalanced. Proper model selection and data preprocessing can improve the reliability of AutoML tools.

[PMID: 39182651 DOI: 10.1016/j.oret.2024.08.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 08/08/2024] [Accepted: 08/19/2024] [Indexed: 08/27/2024]
Abstract
PURPOSE To assess long-term re-detachment rates of the Pneumatic Retinopexy versus Vitrectomy for the Management of Primary Rhegmatogenous Retinal Detachment Outcomes Randomized Trial (PIVOT). DESIGN Randomized controlled trial. SUBJECTS PIVOT trial participants METHODS: This study was performed at St. Michael's Hospital, Unity Health Toronto, Toronto, Canada. PIVOT trial participants, with a minimum follow-up of two years, who had undergone either pneumatic retinopexy or ppv for rrd repair were assessed for long-term re-detachment by chart review or telephone interview. The latter was the only accepted method for those with less than two years of follow-up. Patients were only eligible if no re-intervention to reattach the retina was performed within the first year of the initial procedure. MAIN OUTCOME MEASURES Long-term re-detachment rates for pneumatic retinopexy versus ppv following RRD repair. RESULTS 61 ppv participants and 62 pneumatic retinopexy participants were analyzed. The long-term re-detachment rate was 0% and 1.61% (1/62) in the ppv and pneumatic retinopexy groups, respectively (p= 0.32). The mean follow-up duration in years was 5.43+/-3.60 versus 5.51+/-3.03 in the ppv and pnr groups, respectively. CONCLUSION There was no statistically significant difference in long-term re-detachment rates for pneumatic retinopexy vs ppv. Both procedures are durable treatment options for rrd over an extended period, rarely requiring additional intervention for re-detachment.

Reattachment rate with pneumatic retinopexy versus pars plana vitrectomy for single break rhegmatogenous retinal detachment. Br J Ophthalmol 2024:bjo-2023-324005. [PMID: 39159999 DOI: 10.1136/bjo-2023-324005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Accepted: 06/25/2024] [Indexed: 08/21/2024]
Abstract
AIM To assess the primary reattachment rate (PARR) in pneumatic retinopexy (PnR) versus pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) meeting the Pneumatic Retinopexy versus Vitrectomy for the Management of Primary Rhegmatogenous Retinal Detachment Outcomes Randomised Trial (PIVOT) criteria with a single break in detached retina. METHODS A post hoc analysis of two clinical trials. To be included, patients with primary RRD had to meet PIVOT criteria but could have only one break in the detached retina. Patients with additional pathology in the attached retina were included in a secondary analysis. The primary outcome was PARR following PnR versus PPV at 1-year postoperatively. RESULTS 162 patients were included. 53% (86/162) underwent PnR and 47% (76/162) had a PPV. 99% (85/86) and 86.8% (66/76) completed the 1-year follow-up visits in the PnR and PPV groups, respectively. PARR was 88.2% (75/85) in the PnR group and 90.9% (60/66) in the PPV group (p=0.6) with a mean postoperative logMAR best-corrected visual acuity of 0.19±0.25 versus 0.34±0.37 (Snellen 20/30 vs 20/44) (p=0.01) each in the PnR and PPV groups, respectively.In an additional analysis of patients who were also allowed to have any pathology in the attached retina, the PARR was 85% (91/107) and 91.6% (66/72) in the PnR and PPV groups, respectively (p=0.18). CONCLUSIONS PnR and PPV provide similar long-term PARR in a substantial proportion of patients meeting PIVOT criteria with only a single break in the detached retina. Therefore, in patients meeting these specific criteria, PnR is an appropriate first-line therapy as it offers superior functional outcomes without compromising PARR.

BMC Ophthalmol 2024; 24:287. [PMID: 39014314 PMCID: PMC11251132 DOI: 10.1186/s12886-024-03559-7] [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: 03/21/2024] [Accepted: 07/05/2024] [Indexed: 07/18/2024] Open
Abstract
BACKGROUND To report real-world outcomes of patients with primary Reghmatogenous Retinal Detachment (RRD) treated with Pneumatic Retinopexy (PnR) according to the indications of the Pneumatic Retinopexy versus Vitrectomy for management of Primary Rhegmatogenous Retinal Detachment Outcomes Randomized Trial (PIVOT) trial. METHODS Multicenter, retrospective study. Patients treated with PnR for RRD between 2021 and 2023 and a follow-up of at least 6 months were included. Single-procedure anatomical success, final anatomical success, complications, causes of failures, best corrected visual acuity (BCVA) after surgery, and the vision-related quality of life using the 25-Item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) were reported. RESULTS A total of 76 eyes of 76 patients were included. Mean age was 60 ± 8.1 years. Primary anatomic reattachment was achieved by 84.3% of patients and final anatomical reattachment after pars plana vitrectomy was obtained in 100% of patients. BCVA improved from 0.32 (20/40) to 0.04 (20/20) logMar (p < 0.001) at 6 months. The main cause of failure was related to the presence of additional (likely missed) retinal breaks (66.6% of cases). Also, primary PnR failure was more frequent in eyes of patients with older age, macular involvement, worse baseline BCVA, greater extent of the RRD, and increased duration from diagnosis to treatment. Overall, the mean NEI-VFQ 25 composite score was 93.9% ± 6.4 at 6 months. CONCLUSIONS The criteria of the PIVOT trial can be applied to real-world scenarios in the decision-making process for the treatment of primary RRD, with excellent anatomical and functional outcomes.

Abstract
BACKGROUND To study out types and incidence of the complications and reveal the risk factors that affect anatomical and visual success of pneumatic retinopexy with a high number of rhegmatogenous retinal detachment cases. METHODS Eight hundred and fifty eyes of the 837 patients who admitted at a tertiary center, between January 2015 and January 2022 for the diagnosis of rhegmatogenous retinal detachment, then underwent pneumatic retinopexy and had at least sixth month follow-up, were included in the study. The multivariate logistic regression model was created to investigate the factors affecting anatomical and visual success. RESULTS The anatomical success rate was 53.4% with the first pneumatic retinopexy and 99.8% after subsequent procedures. Visual acuity of >0.4 logMAR (<20/50 Snellen), proliferative vitreoretinopathy, and macular involvement was determined as significant preoperative risk factors for single operation and visual success in all univariate and multivariate analyses. In addition, pseudophakic/aphakic lens status was associated with single operation failure in all analyses. Besides, in all analyzes for single operation and visual success, new or missed tears, proliferative vitreoretinopathy, delayed subretinal fluid, macular hole, and subretinal gas were identified as significant postoperative risk factors. Among these, new or missed tears was determined as the most common complication with a rate of 24%. CONCLUSION There are many risk factors influencing the success of pneumatic retinopexy. These factors and complications should always be considered, before applying this rapid, effective, inexpensive, and minimally invasive method.

Abstract
PURPOSE To compare the efficacy and safety of pars plana vitrectomy (PPV) with silicone oil compared to gas tamponade for uncomplicated rhegmatogenous retinal detachment (RRD). DESIGN Systematic review and meta-analysis. METHODS A systematic literature search was conducted on Ovid MEDLINE, Embase, and the Cochrane Library from January 2000 to September 2023 for comparative studies evaluating the efficacy and safety of PPV with either silicone oil or gas tamponade in the setting of uncomplicated RRD. Our primary outcome was best-corrected visual acuity at the last study observation. Secondary outcomes included the rates of retinal reattachment, retinal thickness, and the incidence of adverse events. We performed a meta-analysis using a random-effects model. RESULTS Nine observational studies reporting on 491 RRD eyes were included. The mean best-corrected visual acuity at the last study observation was significantly better in the gas tamponade group than in the silicone oil group (weighted mean difference [WMD] = 0.17 logMAR, 95% confidence interval [CI] = [0.06, 0.27], P = .002). Rates of primary retinal reattachment were similar between the silicone oil and gas tamponade groups (P = .89). The ganglion cell layer was significantly thinner in the silicone oil group compared to the gas tamponade group (WMD =-3.70 µm, 95% CI = [-5.87, -1.53, P = .0008), as was the inner plexiform layer (WMD = -2.45, 95% CI = [-4.50, -0.40], P = .02) and outer nuclear layer (WMD = -11.74 µm, 95% CI = [-18.39, -5.10], P = .0005). CONCLUSIONS PPV with gas tamponade was associated with better functional outcomes compared to PPV with silicone oil, although both tamponades yielded comparable primary reattachment rates. The absence of randomized trials and the potential for selection bias underscore the importance of further investigation in diverse patient populations.

Abstract
PURPOSE OF REVIEW 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). RECENT FINDINGS No significant trends were found for average number of services ( P = 0.153) of PnR after the publication of PIVOT results. SUMMARY 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.

Management, risk factors and treatment outcomes of rhegmatogenous retinal detachment associated with giant retinal tears: scoping review. Int J Retina Vitreous 2024; 10:35. [PMID: 38654369 PMCID: PMC11036595 DOI: 10.1186/s40942-024-00552-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Accepted: 03/27/2024] [Indexed: 04/25/2024] Open
Abstract
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%). CONCLUSION 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.

[PMID: 37459912 DOI: 10.1016/j.oret.2023.07.010] [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: 05/18/2023] [Revised: 07/11/2023] [Accepted: 07/11/2023] [Indexed: 08/24/2023]
Abstract
PURPOSE To assess clinical outcomes in elderly patients aged ≥ 75 years who underwent pneumatic retinopexy (PnR) for primary rhegmatogenous retinal detachment (RRD). DESIGN Retrospective cohort study. SUBJECTS Patients aged ≥ 75 years with primary RRD undergoing PnR. METHODS This study evaluates clinical outcomes among eligible patients who presented from October 1, 2010, to December 31, 2022, with a minimum of 3 months' follow-up. There were no limitations with respect to the number, size, or location of retinal breaks. Exclusion criteria included significant proliferative vitreoretinopathy or previous retinal detachment repair in the index eye, inability to maintain the postoperative posturing requirements or inability to carry out adequate examination of the peripheral retina because of media opacity. Lens status did not impact the decision to offer PnR. MAIN OUTCOME MEASURES Pneumatic retinopexy primary anatomic reattachment rate and postoperative best corrected visual acuity (BCVA) at 3 months. RESULTS Eighty patients with a mean age of 80.6 ± 4.6 years were included in this study; 35% (28/80) were phakic and 34% (27/80) presented with a fovea-on RRD. The mean number of breaks in the detached retina was 1.52 ± 1.13, and the mean number of quadrants of detached retina was 2.35 ± 0.93. The primary anatomic reattachment rate at 3 months after PnR was 78.8% (63/80), whereas the remaining 21.2% (17/80) failed PnR and underwent an operating room procedure. There was a statistically significant improvement in logarithm of the minimum angle of resolution (logMAR) BCVA from baseline to 3 months (1.29 ± 0.94 and 0.69 ± 0.67, respectively, P < 0.001). A subgroup analysis that only included patients aged > 80 years was also performed, with a total of 39 patients with a mean age of 84.4 ± 3.5 years. The primary anatomic reattachment rate with PnR in this subgroup was 74.4% (29/39), with a statistically significant improvement in BCVA from baseline to 3 months (1.4 ± 1.05 and 0.77 ± 0.70, respectively; P = 0.004). CONCLUSIONS Elderly patients treated with PnR for primary RRD had relatively comparable primary anatomic reattachment rates with other surgical techniques such as pars plana vitrectomy and scleral buckle. Pneumatic retinopexy is an effective, minimally invasive office-based procedure that may be desirable for some elderly patients.

Abstract
BACKGROUND Demarcation line in a rhegmatogenous retinal detachment (RD) is a classic finding noted in chronic cases. In this case report, we describe a case of evolution of post-operative demarcation line after pneumatic retinopexy (PnR) in a subtotal rhegmatogenous RD. CASE DESCRIPTION A 31-year-old male diagnosed with acute, subtotal, macula-off rhegmatogenous RD in the left eye of 15-day duration underwent PnR on the same day. His presenting visual acuity was 6/48 in the left eye. Transconjunctival cryopexy was performed to the retinal break at the same sitting and 0.5 cc of 100% perfluoroproprane (C3F8) gas was injected in the vitreous cavity and right lateral position was advised to the patient. RESULT A pigmentary demarcation line was noted extending the nasal part of the macula along the most dependent part of the detachment on the immediate post-operative day and was more obviously visible on the 2nd and then on the 11th post-operative day. The visual acuity at the last follow-up visit improved to 6/18. Successful reattachment of the retina was noted on the last follow-up visit. CONCLUSION Post-operative demarcation lines after RD surgery could develop due to subretinal migration of pigments and along the most-dependent part depending upon post-operative positioning of the patient. Careful post-operative positioning, particularly in macula splitting RDs could be important to avoid pigment accumulation along the foveal area.

Abstract
BACKGROUND Combined retinal and choroidal detachment (RD-CD) poses significant challenges in ophthalmic treatment, often requiring surgical intervention for optimal outcomes. The selection of the appropriate surgical procedure is crucial for ensuring visual restoration and overall eye health. This study delves into the therapeutic benefits and outcomes of two distinct surgical approaches for RD-CD: pneumatic retinopexy (PR) followed by pars plana vitrectomy (PPV) and PPV alone, in an attempt to guide optimal clinical decision-making. MATERIAL AND METHODS We retrospectively analyzed data from 64 consecutive patients diagnosed with RD-CD. They were categorized into two groups: Group A consisted of 34 patients (34 eyes) who underwent PR as an initial treatment and subsequently received PPV, while Group B, serving as a control, comprised 30 patients (30 eyes) treated solely with PPV. RESULTS The application of PR in Group A notably accelerated intraocular pressure (IOP) increase (P.

Abstract
Purpose The purpose of this study is to retrospectively analyze single-operation success (SOS) rates of pneumatic retinopexy (PR) for the treatment of rhegmatogenous retinal detachment (RRD) and to identify the predictors of treatment outcomes. Methods Sixty-one eyes of 61 patients who underwent PR for RRD during a period of 12 years were included in this study. Patient demographics along with pre-treatment clinical characteristics were recorded. Treatment outcomes in terms of best-corrected visual acuity (BCVA) and anatomical characteristics were reported including any post-operative complications. Visual outcomes were compared according to pre-treatment characteristics and between groups of the eyes achieving SOS and those requiring additional surgery. Results SOS was achieved in 37 (61%) eyes. Twenty-four (39%) eyes required one (36%) or two (3%) additional procedures. There was no significant association between pre-treatment characteristics and treatment failure. SOS eyes had significantly better visual outcomes (P=0.002), and so did those with macula-on status (P=0.003). New/missed breaks (9.8%) and proliferative vitreoretinopathy (PVR) (4.9%) were the most common causes of failure. Conclusions We found PR to be a beneficial technique for the treatment of RRD in this cohort. PR remains the least invasive treatment modality, and as a cost-effective technique, it is especially useful in low/middle-income countries such as Pakistan.

Abstract
This study aimed to demonstrate the laser retinopexy method through the gas bubble under a slit-lamp biomicroscope using a wide-field contact lens to treat rhegmatogenous retinal detachment (RRD) with pneumatic retinopexy (PR) and report its anatomical and functional results. This single-center, retrospective case series included RRD patients treated with PR using sulfur hexafluoride (SF6). The demographics, preoperative factors, and anatomical and functional outcomes were collected from the patient files. The single-procedure success rate of PR at postoperative 6th months was 70.8% (17/24 eyes), and the final success rate after secondary surgeries was 100%. The BCVA was better in the successful PR eyes at postoperative 3rd (p = 0.011) and 6th month (p = 0.016) than in failed eyes. No single preoperative factor was associated with PR success. The single-procedure success rate of PR using the laser retinopexy method through the gas bubble with a wide-field contact lens system seems comparable to the PR literature.

Abstract
Background In young adults with rhegmatogenous retinal detachment, pneumatic retinopexy can be a cost-effective and minimally invasive highly effective method in suitable cases. Objectives To evaluate the role of pneumatic retinopexy in the treatment of young adults with rhegmatogenous retinal detachment (RRD) and the factors that may affect the success of pneumatic retinopexy. Design Retrospective study. Methods The study included 67 eyes of 67 patients aged between 21 and 40 who underwent pneumatic retinopexy (PR) between January 2015 and June 2021 for primary RRD. We retrospectively analyzed the prognostic factors that may affect the success of PR, such as preoperative age, best corrected visual acuity, tear site, lens condition, and axial length. Results PR was successful in 61.2% of the patients, whereas 38.8% required secondary surgery. Between the group that had a single surgery (Group 1) and the group that required secondary surgery (Group 2) the tear location, axial length, and volumes of gases used were statistically different (p = 0.04, p < 0.001, and p = 0.02, respectively). There was a significant difference in visual acuity before and after surgery in the group that was successful with a single surgery (Friedman χ2 = 40.051, p < 0.001). There was no significant difference between the two groups in terms of intraocular pressure (p > 0.05), and glaucoma was not observed in the postoperative period. Conclusion Since it is a minimally invasive and cost-effective method that provides rapid visual rehabilitation, it can be considered as first-line therapy in young adults who are suitable for PR.

Abstract
BACKGROUND AND OBJECTIVE To compare pneumatic retinopexy (PnR) and scleral buckling (SB) for repair of primary rhegmatogenous retinal detachment. MATERIALS AND METHODS Single-centre retrospective analysis of patients undergoing PnR and SB. Inclusion criteria comprehend phakic patients with a single retinal break or a group of breaks in detached retina in the same quadrant above the 8- and 4-o'clock meridians. A total of 184 patients were included, respectively 106 underwent PnR and 78 SB. Follow-up time was 6 months. RESULTS Final visual outcome did not differ significantly between the two procedures (P = 0.12). Single-procedure reattachment rate was significantly higher in SB (94%) than in PnR (68%) (P < 0001). Anatomical success rate was not influenced by macular involving. Reattachment rate in repeated PnR was 95% and in these patients visual outcome did not statistically differ compared to those reattached with first attempt (P = 0.196). Total reattachment rate including repeated procedures was 87% in PnR group and 94% in SB group, the difference was not significant (P = 0.06). CONCLUSION SB has a higher single reattachment rate than PnR. However, final visual outcomes of both procedures are comparable. In selected cases, PnR can be repeated with a high successful rate.

Abstract
The purpose of this manuscript was to design a better method for recovery from rhegmatogenous retinal detachment (RRD) surgery. We attempted to achieve this by designing a helmet that can manipulate intraocular magnetic nanoparticles (MNPs) and create a magnetic tamponade, eliminating the need for postoperative head positioning. A simulated analysis was developed to predict the pattern of magnetic force applied to the magnetic nanoparticles by external magnetic field. No participants were involved in this study. Instead, magnetic flux and force data for three different helmet designs were collected using virtual simulation tools. A prototype helmet was then constructed and magnetic flux and force data were recorded and compared to virtual data. For both virtual and physical scenarios, magnitude and direction of the resulting forces were compared to determine which design created the controlled direction and strongest forces into the back of the eye. Of the three virtual designs, both designs containing a visor had greater force magnitude than magnet alone. Between both designs with visors, the visor with bends resulted in forces more directed at the back of the eye. The physical prototype helmet shared similar measurements to virtual simulation with minimal percent error (Average = 5.47%, Standard deviation = 0.03). Of the three designs, the visor with bends generated stronger forces directed at the back of the eye, which is most appropriate for creating a tamponade on the retina. We believe that this design has shown promising capability for manipulating intraocular MNPs for the purpose of creating a tamponade for RRD.

Abstract
Pneumatic retinopexy (PR) is a minimally invasive, non-incisional procedure for repairing uncomplicated rhegmatogenous retinal detachment. It consists of an intravitreal gas injection followed by the maintenance of a postoperative head position and the use of laser or cryopexy to seal the retinal breaks. It was initially indicated for a single or a group of retinal breaks no larger than 1 clock hour involving the superior 8 clock hours in phakic eyes with no proliferative vitreoretinopathy. We aim to perform a narrative review on pneumatic retinopexy since the last major review of 2008, based on a Medline search up to June 20 2021 using multiple search words including pneumatic retinopexy, pneumoretinopexy, retinal detachment, and pars plana vitrectomy. Indications for PR have been expanded and include pseudophakic eyes, eyes with mild PVR, and even breaks in the inferior fundus. Depending on the case selection, PR has a single-operation success rate ranging from 45 to 80%. Despite the lower single operation success rate, the functional outcomes of those eyes repaired successfully by primary PR exceed those of scleral buckling (SB) and pars plana vitrectomy (PPV). Best corrected visual acuity, metamorphopsia scores, mental health scores, and vision-related functioning scores were all better in PR-treated eyes compared to PPV-treated eyes. PR should be strongly considered for eligible patients with a primary uncomplicated rhegmatogenous retinal detachments.

Abstract
IMPORTANCE Pneumatic retinopexy (PR) is the only clinic-based method of rhegmatogenous retinal detachment (RRD) repair. Registry-acquired clinical practice setting outcomes data with this procedure have not yet been reported. OBJECTIVE To describe the clinical outcomes associated with RRD treated primarily with PR. DESIGN, SETTING, AND PARTICIPANTS In this retrospective cohort study, data from patients 19 years and older with noncomplex RRD treated at academic and private ophthalmology practices participating in the American Academy of Ophthalmology IRIS Registry (Intelligent Research in Sight) were analyzed. Data were collected from January 1, 2013, to December 31, 2019, and data were analyzed from January to December 2020. EXPOSURES Data from the IRIS Registry were queried for eyes that underwent PR for noncomplex RRD and had at least 3 months of follow-up. Cases were identified by a combination of diagnosis code for RRD and a Current Procedural Terminology code for PR. MAIN OUTCOMES AND MEASURES The number of eyes that achieved single-operation success (SOS), defined as retinal reattachment without a subsequent retinal detachment surgery or repeated PR. RESULTS Of 9553 included patients, 5827 (61.0%) were male, and the mean (SD) age was 62 (10) years. A total of 9659 eyes were identified. SOS was achieved in 6613 eyes (68.5%). Best-corrected visual acuity significantly differed 9 to 12 months after treatment between the SOS group, with a mean of 0.24 logMAR (95% CI, 0.23-0.25; approximate Snellen equivalent, 20/35), and the single-operation failure group, with a mean of 0.43 logMAR (95% CI, 0.40-0.46; approximate Snellen equivalent, 20/54). Among all patients, the mean time to maximal visual recovery was 268 days (95% CI, 260-276). Endophthalmitis was observed in 3 eyes (0.03%). SOS was associated with female sex (odds ratio, 1.51; 95% CI, 1.38-1.65), while current smoking status was associated single-operation failure (odds ratio, 0.78; 95% CI, 0.68-0.91). CONCLUSIONS AND RELEVANCE In this registry-based study, which encompasses a large number of eyes drawn from multiple, heterogenous electronic health record systems, SOS was achieved in 68.5% of eyes with noncomplex RRD treated by primary PR. It is unknown how these outcomes would have compared with other methods of RRD repair in this cohort.

Abstract
We describe the new technique of chandelier-assisted pneumatic retinopexy in repairing rhegmatogenous retinal detachments in a series of young adults. In the operating room, a 25-gauge trocar cannula is inserted at the pars plana 180° across the preoperatively detected retinal break followed by Chandelier light insertion, which is used in globe fixation and rotation. The retinal periphery is reexamined using scleral indentation and chandelier light endoillumination. Transconjunctival cryopexy is performed around the break followed by paracentesis and pure sulfur hexafluoride gas injection. Twelve eyes of 12 patients were repaired. Their mean (±SD) age was 29.4 (±3.4) years and preoperative corrected distance visual acuity (CDVA) was 0.36 (±0.32). Nine eyes had 1 break while 3 eyes had 2 breaks within 1 clock hour. Mean duration of operation was 11.7 (±1.8) min. No patient experienced major intraoperative complications, but one patient required reoperation. Mean CDVA 6 months postoperatively was 0.63 (± 0.21) (p < 0.05).

Abstract
Purpose: The purpose of this study is to study single surgery reattachment rate, refractive shift, surgical time, cost, and complications of pneumoretinopexy (PR) compared to scleral buckling (SB) in rhegmatogenous retinal detachments (RRDs) with superior breaks. Methods: Data of RRD with superior breaks, from 2013 through 2016, treated either with PR or SB surgery at a tertiary eye-care center were retrospectively reviewed. Treatment outcomes, procedural costs, refractive shift, surgical time, and complications, namely, cataract and glaucoma, were analyzed. Results: Thirty-two cases treated by PR (n = 15) and SB surgery (n = 17) fulfilled the selection criteria. Macula off RRD (91%) was the commonest presentation. Baseline parameters like duration of vision loss, presenting vision, and ocular characteristics were comparable. Single surgery retinal reattachment (66.7% PR vs. 76.5% SB) was analogous (P = 0.698). Retinal reattachment with secondary intervention was achieved in all cases at the last follow-up. Average vision gain in logMAR of 0.8 in PR and 0.6 in SB was not significantly different (P = 0.645) between the two groups, with SB group having a 1.9 Dioptre myopic shift and PR group none. Surgical time was shorter in PR versus SB at 15 versus 85 min and surgical cost (including additional surgery) was 50% less in PR. Complications like cataract progression (P > 0.99) and glaucoma (P = 0.71) were analogous among the groups. Horse-shoe tears were associated with failed primary surgery in 60% of PR and 75% of SB procedures. Conclusion: In RRDs secondary to superior breaks, PR proved to be faster, more economical, and less tissue manipulative than scleral buckle surgery, with equivalent efficacy and safety profile.

Abstract
PURPOSE To evaluate the visual and anatomical outcomes of reoperations following failure of pneumatic retinopexy (PR) for rhegmatogenous retinal detachment repair and compare the different surgical techniques used in these cases. METHODS The study included 114 eyes of 114 patients who underwent PR for rhegmatogenous retinal detachment and required subsequent surgery for its repair. These included repeated PR, scleral buckling, vitrectomy with gas or silicone oil, and vitrectomy with scleral buckling. The groups were compared for rates of retinal reattachment, visual improvement, and the occurrence of recurrent rhegmatogenous retinal detachment and any other postoperative complications. RESULTS In 91 (79.8%) eyes, the retina was reattached with one additional procedure. The success rate was significantly lower in eyes treated by repeated PR than by other surgical techniques (33 vs. 76-90%; P < 0.001). Visual acuity after PR failure was not significantly different than that at presentation and had improved significantly after surgery for retinal reattachment (P < 0.001). CONCLUSION Pneumatic retinopexy failure was not associated with visual acuity loss, and the outcomes in 79.2% of cases that required only one additional surgery are comparable with those achieved with primary surgery. Poor outcomes were associated with eyes that required more than one additional surgery and that suffered complications.

Abstract
Recent reports suggest that the use of an outpatient-based procedure (pneumatic retinopexy, PR) for retinal detachment repair should be encouraged within the UK, especially in light of Covid-19 and possible restrictions/competing demands on access to operating theatres. It is therefore essential that patients receive comprehensive information about the risks and benefits of this approach compared with a formal surgical repair either by pars plana vitrectomy (PPV) and/or scleral buckling (SB). We report a retrospective case series of retinal detachments (RD) satisfying the strict selection criteria for PR but who were managed with formal surgery. Single-operation success rate for PPV/SB at six months follow-up was 93.8% in our study, higher than published primary success rates for PR (60-80%). When counselling patients for possible PR, the ease, speed and potentially reduced co-morbidity of an outpatient-based procedure needs to be balanced against its significantly higher failure rate in comparison with primary PPV/SB.

Abstract
Pneumatic retinopexy (PR) has been widely advocated for treatment of selected rhegmatogenous retinal detachments: those with small, anterior, superior, retinal breaks and little or no proliferative vitreoretinopathy. It has been suggested that PR is underused and is advantageous because it is an outpatient clinic or office procedure, short in duration, nonincisional, and cost saving - with reduced perioperative morbidity, faster postoperative recovery, better and faster visual recovery, a low rate of complications and a high rate of overall success compared with scleral buckling or pars plana vitrectomy. We reevaluated these advantages to substantiate the effectiveness and efficiency of PR and critically define its role in the treatment of rhegmatogenous retinal detachment. We found that PR has a much higher rate of subsequent reoperation and proliferative vitreoretinopathy than scleral buckling or pars plana vitrectomy for simple, good prognosis rhegmatogenous retinal detachments. PR often involves multiple procedures that largely negates its potential cost savings and subjects the patient to prolonged stress and disability. Scleral buckling rather than PR is ideally suited for simple, good prognosis rhegmatogenous retinal detachments for surgeons who feel comfortable with the technique; alternatively, pars plana vitrectomy is indicated.

Abstract
AIM To demonstrate local dry vitrectomy combined with segmental scleral buckling and viscoelastic tamponade for the treatment of partial rhegmatogenous retinal detachment (RRD) with local vitreous traction in patients at high-risk for proliferative vitreoretinopathy (PVR). METHODS Eleven eyes of 11 patients were retrospectively studied, including 5 retinal dialysis and 6 retinal detachment (RD; 5 eyes with peripheral retinal hole and 1 eye with giant tear). All patients exhibited partial RD and local vitreous traction. Combined local dry vitrectomy without conventional infusion and segmental scleral buckling was performed. Viscoelastic fluid was injected into the vitreous cavity if needed. Demographic information, preoperative and post-operative complications, and outcomes were recorded. RESULTS The mean age of the patients at presentation was 26.55±13.52y. All 11 patients obtained retinal reattachment after a single surgical intervention. Postoperative visual acuities were improved or remained stable in all patients. None of them developed complications, except for temporary mildly increased intraocular pressure in 3 cases. CONCLUSION Combined local dry vitrectomy and segmental scleral buckling are effective for patients of RRD with local vitreous traction. The technique avoids many complications associated with regular surgery and was minimally invasive to both the external and internal eye.
