Rhegmatogenous retinal detachment, a severe eye condition, presents anatomic separation of the neurosensory retina from its outermost layer-the retinal pigment epithelium. Early recognition of this relatively common finding and proper referral of patients to the retinal surgery department is essential in order to minimize its consequent possible severe reduction in vision. Several major surgical methods for the repair of primary rhegmatogenous retinal detachment have been in use over the last several decades, and they all aim to find and close the break in the retina that has caused the detachment. Surgery can be performed as pneumatic retinopexy, pars plana vitrectomy, and/or episcleral surgery (buckling). General surgical trends for reattaching the retina include moving from extraocular to intraocular surgery and from bigger gauge to smaller gauge via minimal invasive vitrectomy surgery (MIVS), with implementing shorter-lasting intraocular tamponades. Surgical options for rhegmatogenous retinal detachment treatment nowadays emphasize gaining retinal reattachment, preferably with one surgery and with minimum damage to the eye. The procedure should not bring secondary eye conditions and complications with severe impairment of visual acuity, and it should be performed on as much as a smaller budget, with possibly peribulbar anesthesia, enabling the patient the quickest possible recovery. It should be adjusted to the patient\'s condition, not to the surgeon\'s skills or preferences.

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.

UNASSIGNED: Simultaneous bilateral rhegmatogenous retinal detachment (RRD) is a rare and challenging condition in ophthalmology. This case report focuses on a modified pneumatic retinopexy technique, designed to improve treatment outcomes for this difficult condition.
UNASSIGNED: A 59-year-old male presented with decreased visual acuity in his right eye for one week. Examination revealed extensive retinal detachment in the right eye with multiple superior breaks and macula off, separated by approximately 3 clock hours. The left eye exhibited one quartile of retinal detachment with superior breaks and macula on. Bilateral simultaneous PR was performed for retinal repair. In the modified PR procedure, 0.7 ml of low-concentration perfluoropropane and 0.7 ml of filtered pure air were intravitreally injected into the right and left eyes, respectively. A head position maneuver was then employed to sequentially close retinal breaks, followed by laser photocoagulation once the surrounding retina reattached. Two days after gas injection, both retinas were completely reattached. Best corrected visual acuity improved to 0.6 in the right eye and 0.9 in the left eye at the 8-month follow-up.
UNASSIGNED: The innovative modified pneumatic retinopexy technique presented in this case report offers a promising new approach for effectively treating simultaneous bilateral rhegmatogenous retinal detachment.

UNASSIGNED: 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.
UNASSIGNED: Retrospective multicenter study.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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).
UNASSIGNED: 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.

BACKGROUND: This study aimed to investigate the incidence of and risk factors for epiretinal membrane (ERM) formation following primary rhegmatogenous retinal detachment (RRD) repair.
METHODS: This comparative, retrospective, single-center cohort study included eyes with primary RRD treated between 2011 and 2023 at Massachusetts Eye and Ear, Boston, Massachusetts, with pars plana vitrectomy (PPV), scleral buckle (SB), PPV+SB, or pneumatic retinopexy (PnR). Demographic, clinical, and surgical parameters were collected from medical records. The primary outcome was the risk of ERM formation, while the secondary outcome was the risk of ERM requiring surgery. Univariable and multivariable Cox regression were performed, and a hazard ratio (HR) and 95% confidence interval (95% CI) were reported.
RESULTS: Overall, 394 eyes were included. The mean age was 58.49 ± 12.8 years, and most patients were male. There was a significantly lower risk of ERM formation following SB compared to PPV in the univariable analysis (HR = 0.2, 95% CI = 0.08-0.60, p = 0.003); however, there was no significant association between treatment modality and ERM formation on multivariable Cox regression controlling for confounding factors (p = 0.24). ERM formation was found more commonly in patients who were older (HR = 1.0 per 1 year increase in age, 95% CI = 1.01-1.04, p = 0.001), those with worse baseline visual acuity (HR = 1.3, 95% CI = 1.09-1.71, p = 0.008), and those with macula-off RRDs (HR = 2.1, 95% CI = 1.41-3.32, p < 0.001).
CONCLUSIONS: Surgical modality does not have a significant impact on the risk of ERM following retinal detachment repair. However, age, baseline visual acuity, and macular status are important predictors of ERM formation after RRD repair.

OBJECTIVE: To evaluate the efficacy of pneumatic retinopexy (PR) in patients undergoing PR as primary treatment for rhegmatogenous retinal detachment (RRD) and analyze the factors associated with success and failure in the studied population.
METHODS: A retrospective chart review was done of patients with RRD treated with PR as primary management method treated at New York Eye and Ear Infirmary of Mount Sinai between January 2017 and December 2021. Primary outcome measured success or failure of PR. Secondary outcome measured best corrected visual acuity (BCVA) after PR. A separate risk analysis was done to identify and stratify risks associated with success and failure of PR.
RESULTS: A total of 179 eyes from 179 patients were included for final analysis. The 83 patients (46.37%) achieved anatomical reattachment of the retina after primary PR with no need for additional surgery. The 96 patients (53.63%) had a failed primary PR and required a PPV and 6 of them required pars plana vitrectomy (PPV) with scleral buckle (SB). In total, 19 cases (10.61%) were done as temporizing pneumatics, 18 (94.74%) underwent PPV, and 1 (5.26%) did not require further intervention. The visual acuities at postoperative month 1 (POM1) for patients who underwent primary PR successfully and for those that underwent PPV after, were 0.58 (20/80) and 1.03 (20/200) respectively. Patients who met Pneumatic Retinopexy Versus Vitrectomy for the Management of Primary Rhegmatogenous Retinal Detachment Outcomes Randomized Trial (PIVOT) criteria had a statistically significant decreased risk of primary PR failing (hazard ratio 0.29, P=0.00). Majority of missed or new breaks were found superotemporally.
CONCLUSIONS: PR is a good treatment option for treating RRDs in patients that meet PIVOT criteria and can be conducted as a temporizing measure. PIVOT criteria and fovea on status decrease the risk of PR failure.

Purpose: To assess the visual and anatomic outcomes of eyes that had secondary scleral buckle (SB) surgery after unsuccessful pneumatic retinopexy (PR) for rhegmatogenous retinal detachment (RRD). Methods: A retrospective study, performed over a 12-year period, comprised patients who had secondary SB procedures after failed primary PR. Clinical parameters (eg, best-corrected visual acuity [BCVA], lens status, macula status, details of RRD and subretinal fluid) were assessed at presentation, before additional procedures, and at follow-up (6 months, 1 year, and last visit). Statistical comparisons were made using Brown-Forsythe and Welch analysis-of-variance tests, with significance levels set at P < .05. Results: Fifty-four eyes with adequate follow-up were included. Forty-four (81.5%) of 54 eyes had successful retinal reattachment with secondary SB alone. The remaining eyes had subsequent pars plana vitrectomy (PPV). Patients presenting with macula-on RRD who had successful secondary SB had no statistically significant change in BCVA from baseline (mean final, 0.23 ± 0.25 logMAR [Snellen 20/34]; P = .999). There was a statistically significant improvement in BCVA in patients presenting with macula-off RRD who had successful secondary SB (mean final, 0.32 ± 0.36 logMAR [20/42]; P < .001 and mean change, -1.06 ± 0.85 logMAR). Ten patients presenting with macula-off RRD who had failed secondary SB had a significant improvement in the final BCVA (mean final, 0.22 ± 0.28 logMAR [20/33]; P = .044), despite the need for an additional PPV to achieve reattachment. Conclusions: Secondary SB remains a good option for RRD repair after unsuccessful PR and may avoid the need for PPV.

Comparisons of the surgical and anatomic results of rhegmatogenous retinal detachment surgery have been investigated previously. A systematic evaluation of the available evidence comparing quality of life outcomes of either pars plana vitrectomy, scleral buckling, or pneumatic retinopexy has not been evaluated to date. This article analyzes whether pars plana vitrectomy, scleral buckling, or pneumatic retinopexy for the treatment of rhegmatogenous retinal detachment results in differing quality of life outcomes.
In February of 2022, a comprehensive search of MEDLINE, EMBASE, CINHAL, and Cochrane Library was conducted for studies on patients treated surgically for rhegmatogenous retinal detachment and included follow-up measurements of quality of life outcomes. Meta-analysis was completed using STATA v. 14.0. The main outcomes of interest were the mean vision-related quality of life score (VRQOL) and SD of VRQOL of each type of surgical procedure.
In this systematic review of 13 distinct trials including follow-up of patient quality of life after rhegmatogenous retinal detachment surgery (n = 1063), a better correlation was found between higher quality of life outcomes with scleral buckling than with pars plana vitrectomy (SMD = 0.62, CI: [0.31, 0.93]). There was also no signficant difference in quality of life outcomes between pneumatic retinopexy and pars plana vitrectomy (SMD = 0.08, CI: [-0.07, 0.22]).
Scleral buckling results in better quality of life outcomes for patients when compared to pars plana vitrectomy. Pneumatic retinopexy did not show a difference in quality of life outcomes compared to pars plana vitrectomy.

UNASSIGNED: In young adults with rhegmatogenous retinal detachment, pneumatic retinopexy can be a cost-effective and minimally invasive highly effective method in suitable cases.
UNASSIGNED: 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.
UNASSIGNED: Retrospective study.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.

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.
