Long-Term Functional Outcomes of Retinal Detachment Due to Acute Retinal Necrosis: A Case Series.

Objectives: To evaluate the long-term anatomical and functional prognosis of patients with retinal detachment (RD) secondary to acute retinal necrosis (ARN) treated with pars plana vitrectomy (PPV). Methods: This retrospective case series included 21 eyes from 21 patients with RD secondary to ARN. The study analyzed vitreous or aqueous biopsy results, the impact of antiviral therapy, time to retinal detachment, changes in visual acuity (VA), and anatomical and surgical outcomes. All cases underwent 23-gauge PPV with silicone oil tamponade, and an episcleral encircling band was used in 11 cases. All patients received systemic antiviral therapy at diagnosis. Results: Retinal reattachment was achieved in 91% of cases during follow-up, with an average follow-up period of 39.5 ± 36.8 months. The average time from ARN diagnosis to RD onset was 33.3 ± 27.5 days. VZV was detected in 10 eyes through PCR analysis. Significant differences in visual prognosis were found between macula-off and macula-on RD (p = 0.048). Eyes with optic nerve head inflammation had worse final VA (p = 0.010). No significant difference was observed between preoperative VA and VA at the end of follow-up (p = 0.665). Conclusions: VZV was the primary virus associated with ARN-related RD. Early involvement of the macula and optic nerve in retinitis negatively impacted the final visual prognosis.

Cost Analysis of Scleral Buckle and Pars Plana Vitrectomy for Retinal Detachment Surgery.

To compare the cost and utility of scleral buckle (SB) and pars plana vitrectomy (PPV) techniques for repairing moderately complex rhegmatogenous retinal detachment (RRD). A cost-utility analysis was conducted using data from the Primary Retinal Detachment Outcomes Study (PRO) and a study conducted by the author. Total costs, patient utility over a lifetime, and cost per quality-adjusted life year (QALY) were calculated for each surgical procedure. The cost of scleral buckle surgery was €287.93, with an estimated lifetime QALY of 7.49. Costs per QALY were €38.44. According to the PRO study and Belin et al, total costs were $5975, with a lifetime QALY of 5.4 and costs per QALY of $1106. The cost of pars plana vitrectomy (PPV) was €1468.26, with an estimated lifetime QALY of 6.84 and costs per QALY of €214.65. Based on the PRO study and Belin et al, total costs were $8125, with a lifetime QALY of 4.7 and costs per QALY of $2196. Repairing moderately complex RRD presents a highly cost-effective profile for both SB and PPV techniques, well below recommended QALY thresholds. SB demonstrated a slightly more favorable profile compared to PPV.

Long-Term Redetachment Rates of Pneumatic Retinopexy versus Pars Plana Vitrectomy in Retinal Detachment: A PIVOT Post Hoc Analysis

PurposeTo assess long-term re-detachment rates of the Pneumatic Retinopexy versus Vitrectomy for the Management of Primary Rhegmatogenous Retinal Detachment Outcomes Randomized Trial (PIVOT). DesignRandomized controlled trial. SubjectsPIVOT trial participants MethodsThis 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 MeasuresLong-term re-detachment rates for pneumatic retinopexy versus ppv following RRD repair. Results61 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. ConclusionThere 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.

Pneumatic retinopexy for primary rhegmatogenous retinal detachment: from a clinical trial to the real-life experience

BackgroundTo 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.MethodsMulticenter, 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.ResultsA 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.ConclusionsThe 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.

Impact of drainage retinotomy on surgical outcomes of retinal detachment: insights from the Japan-Retinal Detachment Registry

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.

Surgical Outcomes of Retinal Detachment in Knobloch Syndrome

To describe the rate, characteristics, and outcomes of rhegmatogenous retinal detachment (RD) in patients with Knobloch syndrome. A single-center retrospective cohort study. 50 patients with Knobloch syndrome diagnosed clinically with or without molecular confirmation of recessive pathogenic COL18A1 variants. A retrospective chart review of all patients diagnosed with Knobloch syndrome from November 1st, 1983, to March 31st, 2023. Demographic data, ophthalmic evaluation at baseline and follow-up, interventions, and final anatomic and visual outcomes were collected. Rate, time of onset, characteristics, and treatment outcomes of RD. Fifty patients with Knobloch syndrome were included. Males constituted 56% of cases. The diagnosis was confirmed with molecular genetic testing in 37 (74%) patients. 22 patients (44%) had documented occipital bony defects or scalp lesions. Forty-eight of 100 eyes (48%) developed RD at a mean age of 6.5 (SD = 6.1) years. The mean follow-up was 7.7 (SD = 5.6) years [range 6 months - 24.3 years]. Macular hole-related RD comprised 33% of RD cases. The overall single surgery success rate was 36% and the final anatomical success rate was 70%. Macular hole-related RD carried a slightly worse prognosis with a 58% final anatomical success rate. Vitrectomy with adjunct scleral buckle and silicone oil tamponade provided the highest single surgery success (62.2%). In eyes with measurable best corrected visual acuity (BCVA), the mean preoperative BCVA was 1.2 logMAR (Snellen equivalent 20/320). After successful repair, mean VA was 1.3 logMAR (Snellen equivalent 20/500). Retinal Detachment in Knobloch syndrome is frequent and occurs in young children. Macular hole retinal detachment comprises one-third of RD cases and requires careful macular evaluation. Vitrectomy, combined with scleral buckling and silicone oil tamponade appear to provide the best anatomical outcomes.

Outcomes and variables that impact pneumatic retinopexies.

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. 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. 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. 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.

Pediatric retinal detachment: Anatomical and visual outcomes from tertiary eye center in Nepal

Abstract Objective: The aim is to evaluate the anatomical and functional outcomes of retinal detachment (RD) surgery in the pediatric population in a tertiary eye hospital in Nepal. Methods: This study is a hospital-based, retrospective cross-sectional study, including patients under 18 years of age, diagnosed with rhegmatogenous RD (RRD) for 5 years from January 2015 to December 2019, who underwent RD surgery. Results: Twenty patients were included in the study (mean age of 10.75 ± 2.63). Male patients were 19 (95%). A history of trauma was seen in 13 (65%) patients. Phakic RRD was observed in 18 (90%) patients and the rest 2 (10%) patients were pseudophakic. Type B proliferative vitreoretinopathy changes were observed in 3 (15%) patients, type C was observed in single patient (5%). Scleral buckling was performed in 7 (35%) patients, while 12 (60%) patients underwent three-port pars plana vitrectomy (PPV) and silicon oil instillation and the remaining single patient (5%) underwent PPV with gas exchange. Lensectomy was performed in 8 (40%) patients. Retinal attachment with a single surgical procedure was seen in 8 (40%) patients, while 12 (60%) patients required multiple surgeries. The mean duration of silicon oil removal was 5 ± 2.78 months (1–11 months). At the end of 6 months, 11 (55%) patients had improved visual acuity of 6/60. Six months postoperatively, 18 (90%) patients had attached retina. Conclusion: Visual improvement and retinal reattachment could be achieved with early diagnosis and intervention in pediatric RRD.

REtinal Detachment Outcomes Study (REDOS): study protocol for a factorial, randomized controlled trial

BackgroundFew large randomized controlled trials provide strong evidence to guide surgical repair of primary rhegmatogenous retinal detachment (RRD) repair. The purpose of this factorial, single-blind, randomized controlled trial is to analyze and compare the surgical outcomes, functional visual outcomes, complications, and quality of life associated with RRD repair using (A) pars plana vitrectomy only (PPV) or PPV with scleral buckle (PPV-SB) and (B) sulfur hexafluoride gas (SF6) or perfluoropropane gas (C3F8) tamponade.MethodsEligible patients with moderately complex RRD will be randomized 1:1 to PPV or PPV-SB and 1:1 to SF6 or C3F8 gas tamponade. Approximately 560 patients will be recruited to be able to detect a difference of around 10% in SSAS rate between the groups. Patients will be followed using multimodal imaging and quality of life questionnaires after the surgical repair until 1 year postoperative. The primary outcome will be a single-surgery anatomic success (SSAS), defined as the absence of reoperation for recurrent RRD in the operating room. Secondary outcomes will be pinhole visual acuity (PHVA) at 8–10 weeks and 6 months, final best-corrected visual acuity (BCVA), final retina status (i.e., attached or detached), time to onset of RRD recurrence, severity and number of complications, and questionnaire results.DiscussionThis will be the first 2 × 2 factorial RCT examining repair techniques in primary RRD. It will also be the first RCT to compare gas tamponade between the two most common agents. Notably, it will be adequately powered to detect a clinically significant effect size. The use of multimodal imaging will also be a novel aspect of this study, allowing us to compare head-to-head the impact of adding an SB to the retina’s recovery after RRD repair and of differing gas tamponades. Until now, the treatment of RRD has been largely guided by pragmatic retrospective cohort studies. There is a lack of strong evidence guiding therapeutic decisions and this trial will address (1) whether supplemental SB is justified and (2) whether longer duration gas tamponade with C3F8 is necessary.Trial registrationClinicalTrials.gov NCT05863312. Registered on 18 May 2023.

The effect of patient symptom awareness on the visual outcome in retinal detachment.

To explore whether a patient's prior knowledge of the symptoms associated with rhegmatogenous retinal detachment (RRD) relates to the visual outcome after treatment. We performed a prospective survey study on 126 patients receiving treatment for primary RRD between March and July 2021. Thirty-seven per cent (n = 47) of patients responded that they were aware of the RRD symptoms prior to the detachment. A history of RRD in the fellow eye or knowledge of family members treated for RRD was frequently reported as a reason for the patient's awareness of RRD symptoms. Patients aware of RRD symptoms presented significantly more often with an attached macula (χ2, p = 0.002) and a better visual outcome following surgery (Mann-Whitney U, p = 0.028) compared to patients who were not aware of RRD-related symptoms. Among 76 patients with a myopic refractive error, only 15% (n = 11) indicated that they had been warned about the increased RRD risk related to myopia, suggesting that three-quarters of patients were not actively informed by their eye care professionals. RRD symptom awareness is significantly related to a higher rate of macula-on RRDs and better visual outcomes after treatment. There is limited awareness of increased RRD risk in myopic RRD patients. These findings suggest that counselling individuals at high risk of RRD about related symptoms is inadequate and better counselling may improve visual outcomes following RRD treatment.

Outcomes of vitreoretinal surgery in eyes with retinitis pigmentosa without retinal detachment.

Outcomes of retinal detachment (RD) have been discussed in detail in many reports of patients with retinitis pigmentosa (RP). This study tries to understand the outcomes of vitreoretinal (VR) surgery for indications other than RD in the eyes with RP. This is a retrospective study that includes clinical data from January 2013 to December 2021. Patients with RP who were treated with a VR surgical intervention were included in the study. The primary outcome of the study was to assess the changes in best-corrected visual acuity. Forty-four eyes of 40 patients with RP were included in the study. Nearly half of the eyes (43%, 19/44) presented from 1month to 1year after the onset of diminished vision, with or without floaters. The mean ± standard deviation (SD) best-corrected visual acuity (BCVA) at presentation was 1.30 ± 0.79 logMAR (20/400 ± 20/125). The major surgical indications were vitreous opacities (43.2%, 19/44) and subluxated/dislocated cataractous lenses (25%, 11/44). The median follow-up duration was 8months (interquartile range (IQR): 1.5-27). Approximately 77% (34/44) of the eyes had improvement in vision. The mean postoperative BCVA at the last follow-up was 0.95 ± 0.73 logMAR (p-value: 0.03). Most eyes with RP recovered well after VR surgical interventions, with short-term improvements in visual acuity. It may be crucial to address the vitreous opacities and membranes as they hinder the residual central island of vision in RP. However, appropriate counselling is required regarding the progressive nature of retinal neuronal degeneration.

Anatomical and functional outcomes of retinal detachment associated with nontraumatic giant retinal tears compared to simple rhegmatogenous retinal detachment

BackgroundTo compare the functional and anatomical outcomes of primary surgery in patients with giant retinal tear (GRT)-associated retinal detachment (GRT-RD) to patients with simple rhegmatogenous RD (RRD).MethodsThis is a retrospective study at the CHU de Québec - Université Laval. Medical records of all consecutive patients operated for RD between 2014 and 2018 were reviewed. Patients with GRT-RD and RRD were included. Preoperative, intraoperative, and postoperative data were compared between both groups, including extension of giant tears, number of RD quadrants, preoperative macula and lens status, type of surgery, best corrected visual acuity (BCVA) in logarithm of the minimum angle of resolution (logMAR) preoperatively and at follow-up, and single surgery anatomical success (SASS).ResultsThere were 39 patients (1.7%) with GRT-RD and 1661 patients (74%) with RRD. Median [Q1, Q3] ages were 59 [52, 62] years and 62 [56, 69] years (p = 0.003), while number of affected quadrants were 2 [2, 3] and 2 [2, 3] (p = 0.96) in GRT-RD and RRD patients, respectively. In GRT-RD patients, GRT size was 120 [90, 150] degrees. Final BCVA was 0.30 [0.10, 0.30] and 0.30 [0.10, 0.40] (p = 0.76) in GRT and RRD patients, respectively. SSAS was 82% (32/39) in the GRT-associated-RD group and 90% (1495/1661) in the RRD group (p = 0.10). After correcting for other preoperative factors, GRT was a risk factor for worse SSAS (odds ratio: 0.422, p = 0.047).ConclusionsGRT-RD is still challenging to treat, and our results suggest that it is a risk factor for poorer SSAS.

Socioeconomic disadvantage and impact on visual outcomes in patients with viral retinitis and retinal detachment

While socioeconomic disparities impact clinical care and patient outcomes, their impact on the anatomic and visual outcomes of retinal detachment in patients with viral retinitis is unstudied. This case series included 18 eyes in 18 patients from a single academic institution between January 1, 2008 and December 31, 2018. Patient characteristics including age, sex, race, ethnicity, insurance, immunosuppression, viral retinitis, retinal detachment, retinal detachment repair, visual and anatomic outcomes, missed appointments, and Area Deprivation Index [ADI] were collected. The low-ADI group, indicating less socioeconomic disadvantage, was comprised of twelve patients with national ADIs less than 38, and the high-ADI group of six patients with national ADIs greater than 38. High-ADI patients tended to be younger (average age 38.0 versus 51.3; P = 0.06), of female sex (P = 0.03), and had more missed appointments (median 11.0 vs 0; P = 0.002). A similar number of patients in both the high-ADI and low-ADI groups underwent pars plana vitrectomy alone or pars plana vitrectomy with scleral buckle. Visual acuity was similar in the high-ADI group than in the low-ADI group at baseline, but worse at the final follow-up visit (P = 0.004). Post-operative and final visit ocular hypotony were more common in the high-ADI group (P = 0.02). In our series, socioeconomic disadvantage negatively affects the visual outcomes in patients with viral retinitis associated-retinal detachments. These factors should be considered by ophthalmologists when treating these patients.

A Splicing Mutation in Slc4a5 Results in Retinal Detachment and Retinal Pigment Epithelium Dysfunction.

Fluid and solute transporters of the retinal pigment epithelium (RPE) are core components of the outer blood–retinal barrier. Characterizing these transporters and their role in retinal homeostasis may provide insights into ocular function and disease. Here, we describe RPE defects in tvrm77 mice, which exhibit hypopigmented patches in the central retina. Mapping and nucleotide sequencing of tvrm77 mice revealed a disrupted 5’ splice donor sequence in Slc4a5, a sodium bicarbonate cotransporter gene. Slc4a5 expression was reduced 19.7-fold in tvrm77 RPE relative to controls, and alternative splice variants were detected. SLC4A5 was localized to the Golgi apparatus of cultured human RPE cells and in apical and basal membranes. Fundus imaging, optical coherence tomography, microscopy, and electroretinography (ERG) of tvrm77 mice revealed retinal detachment, hypopigmented patches corresponding to neovascular lesions, and retinal folds. Detachment worsened and outer nuclear layer thickness decreased with age. ERG a- and b-wave response amplitudes were initially normal but declined in older mice. The direct current ERG fast oscillation and light peak were reduced in amplitude at all ages, whereas other RPE-associated responses were unaffected. These results link a new Slc4a5 mutation to subretinal fluid accumulation and altered light-evoked RPE electrophysiological responses, suggesting that SLC4A5 functions at the outer blood–retinal barrier.

Prospective for Diagnosis and Treatment of Diabetic Retinopathy.

Diabetic retinopathy is a posterior eye disorder in which damage occurs to the light sensitive retina due to diabetes mellitus. This disorder specifically affects people aged between 18-64 with type ІІ diabetes. This disease progresses through different pathophysiological pathways, which include oxidative stress, inflammation, stimulation of the growth factor in the eye's vasculature, isoforms of protein kinase C, and also the activation of the hexosamine pathway. It starts as micro aneurysms and advances in complicated stage, which results in retinal detachment. Treatment of posterior eye diseases has complications due to the structural design of the eye and physiological barriers present. The current treatment approach involves the use of intravitreal anti- VEGFs, corticosteroids implants, laser and surgery; these treatment methods have drawbacks attributed to them despite their benefits. The development of a robust delivery system with minimal or no invasion to tackle the issues of diabetic retinopathy will be of considerable benefit to patients having diabetic retinopathy; the dependency on ophthalmologists for multiple injections will significantly reduce and provide a promising approach in drug delivery. In this review article, the authors provided information related to existing treatment methods available for diabetic retinopathy, the most significant among which is nanotechnology approach through which local delivery via the ocular route to posterior eye can be achieved. It also possesses the various carriers studied for the non-invasive approach for retinal delivery of medicaments. Non-invasive approach for delivery of drugs can be considered as potential for the treatment of diabetic retinopathy.

COST ANALYSIS OF SCLERAL BUCKLE, PARS PLANA VITRECTOMY, AND PARS PLANA VITRECTOMY WITH SCLERAL BUCKLE FOR RETINAL DETACHMENT REPAIR.

To compare the cost and utility of scleral buckle (SB), pars plana vitrectomy (PPV), and PPV with SB (PPV/SB) for moderately complex rhegmatogenous retinal detachment repair. Cost-utility analysis using data from the Primary Retinal Detachment Outcomes Study. The model estimated costs, lifetime utility, and lifetime cost per quality-adjusted life year for treatment of moderately complex rhegmatogenous retinal detachment with SB, PPV, or PPV/SB. Data from the Centers for Medicare and Medicaid Services were used to calculate costs in hospital and ambulatory surgery center settings. Total costs (2020 US dollars) for repair of a moderately complex rhegmatogenous retinal detachment in hospital (ambulatory surgery center) settings were $5,975 ($3,774) for the SB group, $8,125 ($5,082) for the PPV group, and $7,551 ($4,713) for the PPV/SB group. The estimated lifetime quality-adjusted life years gained were 5.4, 4.7, and 4.7 in the SB, PPV, and PPV/SB groups, respectively. The cost per quality-adjusted life year for hospital and ambulatory surgery center settings was $1,106 a ($699) for the SB group, $1729 ($1,081) for the PPV group, and $1,607 ($1,003) for the PPV/SB group. Scleral buckle, PPV, and PPV/SB yielded very favorable cost-utility results for the repair of moderately complex rhegmatogenous retinal detachment, with slightly better results for SB, compared with current willingness to pay standards.
