AimTo report anatomical and functional outcomes after surgical repair of acute-onset vs delayed-onset rhegmatogenous retinal detachments (RDs) following acute posterior vitreous detachment (PVD).MethodsA retrospective, comparative interventional cohort study where patients...

Comparison of the Safety and Efficacy of a 3-Dimensional Heads-up Display vs a Standard Operating Microscope in Retinal Detachment Repair.

Purpose: To evaluate the safety, efficacy, and efficiency of the Ngenuity 3-dimensional (3D) heads-up display (HUD) visualization system for primary rhegmatogenous retinal detachment (RRD) repair at a large academic medical center in the United States. Methods: This retrospective review comprised consecutive patients aged 18 years or older who had primary RRD repair (pars plana vitrectomy [PPV] alone or combined PPV and scleral buckle) performed by the same fellowship-trained vitreoretinal surgeon using the 3D visualization system and a traditional standard operating microscope (SOM) at Massachusetts Eye and Ear from June 2017 to December 2021. The minimum follow-up was 90 days. Results: The 3D HUD group comprised 50 eyes of 47 patients and the SOM group, 138 eyes of 136 patients. There were no between-group differences in single surgery anatomic success rates at 3 months (98% HUD vs 99% SOM; P = 1.00) or at the last follow-up (94% HUD vs 98% SOM; P = .40). The rate of postoperative proliferative vitreoretinopathy was similar between the 2 groups (3 months: 3% HUD vs 5% SOM, P = .94; last follow-up, 2% HUD vs 3% SOM, P = .93). There was no difference in the mean duration of surgery (57.4 ± 28.9 minutes HUD vs 59.4 ± 29.9 minutes SOM; P = .68). Conclusions: Anatomic and functional outcomes, in addition to surgical efficiency, of noncomplex primary RRD repair with a 3D HUD system were similar to those of surgery performed with an SOM.

Rates of Fellow Eye Macular Hole Development During Long Term Follow-Up

Identify the long-term rate of fellow eye full-thickness macular hole (FTMH) development. In this single site, single provider retrospective consecutive case series, idiopathic FTMH patients who underwent surgery from 2003 to 2014 who also had at least 5 years of follow-up information within our electronic medical record (EMR) which was started in 2014 were identified. Cases with secondary causes (ie, trauma), high myopia, bilateral FTMH on presentation, previous retinal surgery, retinal breaks, or intraocular inflammation were excluded. Demographics, medical and ocular history, refractive error, phakic status, best corrected visual acuity, follow-up duration, surgical technique, single operation anatomic success, and reoperations were recorded. The rate of fellow eye FTMH was 2.6% (2/77) at 1 year, 5.2% (4/77) at 3 years, 9.1% (6/66) at 6 years, and 9.1% (7/77) as of final follow up. There were 2 cases by year 1, 2 additional cases by year 3, 2 additional cases by year 6, and 1 additional case reported thereafter. The average follow up was 11.1 ± 4.5 years. There was no significant difference in visual outcomes between primary eyes and fellow eyes. There was no significant difference in gender, age, ocular comorbidities, refractive error, phakic status, and visual acuity between the unilateral and bilateral groups. The rate of FTMH in the fellow eye was low but significant, increased during long-term follow up, and may stabilize after 6 years.

Five-Year Visual Acuity Outcomes of Fovea-Involving Rhegmatogenous Retinal Detachments Following Pars Plana Vitrectomy (PPV) or Combined PPV/Scleral Buckle.

Macular involvement is considered a poor prognostic factor for visual recovery after rhegmatogenous retinal detachment (RRD) repair. Few prior studies report outcomes longer than 2 years after repair with pars plana vitrectomy (PPV) or combined PPV/scleral buckle (SB). The purpose of this study is to evaluate long-term (at least 5 years) visual outcomes following fovea-involving RRD repair with PPV or PPV/SB. This retrospective case series evaluated eyes that underwent fovea-involving RRD repair with PPV or PPV/SB. Eyes with single surgery anatomic success and 5 years or more of follow-up were included. Eyes with other ophthalmic pathology affecting central vision were excluded. Paired analysis compared changes in best visual acuity (BVA) between two timepoints. Fifty-one eyes were included. Median (interquartile range, IQR) time to final follow-up was 7 (IQR: 3) years. Median pre-operatively BVA was 19.95 (IQR: 41.25) letters and improved to 80.15 (IQR:15.05) letters and 80.16 (IQR: 8.80) letters at the 1-year and final follow-up, respectively (P < 0.001). Thirteen of 45 eyes (28.89%) had an improvement in BVA of at least 10 letters from the 1-year to the final follow-up. Average BVA was 20/40 or better in 35/45 eyes (75.56%) at 1-year and 45/51 eyes (88.24%) at final follow-up. No eye had an average BVA of 20/200 or worse at final follow-up. Patients with fovea-involving RRD successfully repaired with PPV or PPV/SB have favorable long-term visual acuity outcomes. BVA may continue to significantly improve even beyond 1 year after surgery. The majority of patients have a BVA of 20/40 or better 5 years after surgery. [Ophthalmic Surg Lasers Imaging Retina 2022;53:674-680.].

360 DEGREE ENDOLASER VERSUS FOCAL ENDOLASER IN PRIMARY RHEGMATOGENOUS RETINAL DETACHMENT REPAIR.

To determine the efficacy of the 360-degree endolaser (360EL) versus focal laser during primary vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) repair. A single-site retrospective chart review was performed on 241 patients who underwent PPV for primary RRD. Patients were assigned to two groups, PPV with 360EL (n = 183) and PPV without 360EL (n = 59). Only cases where surgeons performed 360EL on all RRDs or surgeons who never perform 360EL on RRDs were included. The single surgery anatomical success rate in the 360EL group was 90.2% compared with 86.5% with focal laser ( P = 0.619). Epiretinal membrane formation in 360EL group at 1 year was 44.4% versus 37% with focal laser ( P = 0.429). Cystoid macular edema formation within 1 year of surgery was 25.8% in 360EL group versus 11.9% with focal laser ( P = 0.04). The use of 360EL in PPV for RRD repair does not improve single-surgery anatomical success in routine RRDs when compared with PPV with focal laser.

Localized versus 360-degree laser photocoagulation with limited pars plana vitrectomy in the management of primary rhegmatogenous retinal detachment

BackgroundTo compare the efficacy of intraoperative localized and 360-degree laser photocoagulation in 23-gauge limited pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD).MethodsThis retrospective, comparative, consecutive, interventional study included 155 eyes of 155 patients who underwent primary repair of RRD utilizing 23-gauge PPV with at least six months of follow up. Medical records were retrospectively reviewed, and the corresponding demographic data, preoperative ophthalmic features, surgical management, and postoperative course were recorded. Main outcome measures included single surgery anatomical success, pre- and post-operative visual acuity, and complications.ResultsEighty-three patients (group A) received localized laser photocoagulation in PPV, while the remaining 72 patients (group B) received underwent circumferential 360-degree laser photocoagulation in PPV. Two skilled-surgeons performed all the surgeries, and 23-gauge PPV instrumentation, a wide-angle viewing system, endolaser photocoagulation, and gas tamponade were used in each case. No significant difference was identified in baseline characteristics. The single surgery anatomical success rate was 96.4 % in group A, and 95.8 % in group B, showing no significant difference (p = 1.00). Primary anatomical failure was caused by re-detachment due to break in 2 eyes in each group (no new break 1 eye, new break 1eye in group A, 2 eyes with no new break in group B), and proliferative vitreoretinopathy in 1 eye in each group. Other complications were epiretinal membrane in 7 eyes (3 in group A, 4 in group B), and macular hole in 1 eye in group B. There were no differences in pre- and post-operative best-corrected visual acuity (BCVA) as well as BCVA improvement (p=0.144, p=0.866 and p=0.263, respectively).ConclusionLocalized laser photocoagulation showed no difference in anatomic and visual outcome in RRD patients, when compared with 360-degree laser photocoagulation in limited PPV. Routine circumferential 360-degree laser photocoagulation may not be necessary in vitrectomy surgery for primary rhegmatogenous retinal detachment without severe PVR.

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.

A Comparative Study of Traditional Scleral Buckling to a New Technique: Guarded Light Pipe with Heads-Up Three-Dimensional Visualization.

PurposeThe guarded light pipe is a recently described alternative endoillumination technique to chandelier illumination. We sought to compare the outcomes of scleral buckling (SB) under indirect ophthalmoscopy (ID) to heads-up three-dimensional visualization with a guarded light pipe (3DGLP).MethodsA retrospective comparative study was performed, including 47 eyes that underwent SB for rhegmatogenous retinal detachment (RRD) repair with either traditional ID (n = 31) or 3DGLP (n = 16).ResultsThe single surgery anatomic success rate was 87.0% in the ID group and 87.5% in the 3DGLP group. The final anatomic success rate was 100% in both groups. The median (interquartile range) post-operative logMAR was 0.10 (0.0–0.20) in the ID group and 0.08 (0.02–0.69) in the 3DGLP group (p = 0.51). The median operative time was 107 (94–123) minutes in the ID group and 100 (90–111) minutes in the 3DGLP group (p = 0.25). Among eyes that underwent subretinal fluid drainage, the operative time was significantly longer in the ID group compared to the 3DGLP group, 113 (100–135) minutes vs 93 (85–111) minutes (p = 0.035). There were no post-operative complications in the ID group and one complication of self-resolving vitreous hemorrhage associated with a malfunctioning cryoprobe in the 3DGLP group (p = 0.34). There were no cases of post-operative cataract progression in either group.ConclusionCompared to traditional SB, 3DGLP improves ergonomics and educational value with similar anatomical, visual, intra and post-operative outcomes and may result in shorter operative time in cases requiring subretinal fluid drainage.

Outcomes of Retinectomy without Lensectomy in Rhegmatogenous Retinal Detachments with Proliferative Vitreoretinopathy

To report the anatomic and functional outcomes of retinectomy without lensectomy in eyes with rhegmatogenous retinal detachment (RRD) and proliferative vitreoretinopathy (PVR). Retrospective, noncomparative, and interventional case series. One hundred twelve eyes of 112 patients with RRD complicated by PVR who underwent retinectomy without lensectomy. Retrospective review of patients treated with vitrectomy and retinectomy without lensectomy from January 1, 2015, to January 1,2020. The primary outcome was the final attachment rate and single surgery anatomic success (SSAS) at 3 and 6 months after retinectomy. Secondary outcomes included predictors of final visual acuity (VA), the mean number of subsequent operations required for complete retinal reattachment, cataract surgery, and the number of eyes that ultimately had successful silicone oil removal. Complete final retinal reattachment was achieved in 111 of 112 (99.1%) patients, with a mean (standard deviation [SD]) follow-up of 29 (14) months (range, 8-62 months) after retinectomy. The SSAS was achieved in 84 of 112 (75%) patients at 3 months and 73 of 112 (65.2%) patients at 6 months. The final VA improved or stabilized in 76 of 112 (67.9%) eyes. Silicone oil removal was performed in 72 of 112 patients (64.3%) at a mean (SD) of 6.6 (3.3) months, and cataract surgery was performed on 101 (90.2%) eyes before the last follow-up visit. Retinectomy without lensectomy to repair RRDs complicated by PVR showed acceptable anatomic and functional results. This study suggests that removing the lens when there is no significant cataract may not be necessary in these cases to obtain reasonable outcomes.

Utility of Removal of Vitreous Cortex Remnants during Vitrectomy for Primary Rhegmatogenous Retinal Detachment Repair

Purpose To investigate the prevalence of vitreous cortex remnants (VCR) in primary rhegmatogenous retinal detachment (RRD) and the utility of VCR removal using diamond-dusted membrane scrapers (DDMS) during pars plana vitrectomy (PPV). Methods One hundred and eighty-seven eyes (187 consecutive patients) were retrospectively studied. We evaluated the prevalence of VCR on the retinal surface extending from the macula to outside the vascular arcade in eyes that underwent PPV for primary RRD by a single surgeon between July 2014 and February 2021. The VCR outside the vascular arcade was completely removed using a DDMS. Preoperative factors and surgical outcomes were compared between eyes with VCR removed intraoperatively to those without VCR. Results VCR was present and removed (group A) in 86 (46%) eyes and absent (group B) in 101 (54%) eyes. Patients with VCR were significantly older than those without (p = 0.006). The preoperative BCVA (logMAR) tended to be worse in group A (1.23 ± 0.92 [Snellen equivalent, 20/340]) than in group B (1.03 ± 0.89 [20/214]), however, the difference was not statistically significant (p = 0.095). There were no between-group differences in postoperative BCVA (group A; 0.44 ± 0.54 [20/55]; group B; 0.42 ± 0.50 [20/53]; p = 0.38). Single surgery anatomic success (group A; 90%, group B; 91%, p = 0.573) and the incidence of postoperative PVR (group A; 9%, group B; 6%, p = 0.554) were comparable between the groups. Conclusions Nearly half of the patients had VCR, which was more likely to occur in older patients. VCR removal resulted in favorable functional and anatomic outcomes similar to those in eyes without any VCR in patients with RRD.

AIR VERSUS SULFUR HEXAFLUORIDE GAS TAMPONADE IN VITRECTOMY FOR UNCOMPLICATED RETINAL DETACHMENT WITH INFERIOR BREAKS

To compare surgical outcomes of filtered air and sulfur hexafluoride (SF6) as an internal tamponade in patients undergoing primary 25-gauge pars plana vitrectomy for uncomplicated rhegmatogenous retinal detachment with inferior breaks. Patients with uncomplicated rhegmatogenous retinal detachment associated with inferior breaks (between 4 and 8 o'clock positions) who were undergoing primary pars plana vitrectomy were enrolled. All eyes underwent pars plana vitrectomy and complete drainage of subretinal fluid, followed by filtered air or 20% SF6 tamponade. The main outcome measures included single-surgery anatomical success rates and final visual recovery. Overall, 116 eyes of 116 patients (81 men and 35 women with a mean age of 55.2 years) were assessed. Air was used in 52 eyes (air group) and gas in 64 eyes (gas group). Single-surgery anatomical success was achieved in 50 (96.2%) and 60 (93.8%) eyes in the air and gas groups, respectively (P = 0.69), and final anatomical success was achieved in all eyes. The mean final Snellen visual acuity was similar in the air (20/23) and gas groups (20/21; P = 0.13). No significant differences were observed in single-surgery anatomical success rates and final visual recovery when comparing air with SF6 gas tamponade in pars plana vitrectomy for primary uncomplicated rhegmatogenous retinal detachment with inferior breaks.

OUTCOMES IN PRIMARY UNCOMPLICATED RHEGMATOGENOUS RETINAL DETACHMENT REPAIR USING PARS PLANA VITRECTOMY WITH OR WITHOUT SCLERAL BUCKLE.

To compare outcomes after primary uncomplicated rhegmatogenous retinal detachment repair using pars plana vitrectomy (PPV) or PPV with scleral buckle (PPV-SB). This is a retrospective cohort study with propensity score analysis in a single tertiary care center between 2014 and 2018 comparing patients with primary uncomplicated rhegmatogenous retinal detachment repaired using PPV only or PPV-SB (full cohort: n = 1,516, propensity-matched cohort: n = 908). The primary outcome was single surgery anatomic success, whereas secondary outcomes were 3-month and final pinhole visual acuity in logarithm of the minimum angle of resolution and final retina status. In the full cohort, single surgery anatomic success was achieved in 745 (91%) PPV patients versus 623 (89%) PPV-SB patients (P = 0.13). This was 390 (92%) versus 314 (88%) in phakic patients (P = 0.06) compared with 353 (91%) versus 301 (90%) in pseudophakic patients (P = 0.79), respectively. After matching, single surgery anatomic success was achieved in 424 (93%) PPV patients versus 412 (91%) PPV-SB patients (P = 0.14). Median pinhole visual acuity after PPV was better at 3 months (PPV: 20/40 vs. PPV-SB: 20/50; both cohorts: P < 0.001) and final follow-up (PPV: 20/29 vs. PPV-SB: 20/38; full cohort: P < 0.001 and PPV: 20/29 vs. PPV-SB: 20/36; matched cohort: P < 0.001). Addition of scleral buckle does not significantly change the rate of single surgery anatomic success compared with PPV only in primary uncomplicated rhegmatogenous retinal detachment. It is also associated with worse pinhole visual acuity at follow-up.

Surgical Outcomes of Acute Retinal Necrosis–Related Retinal Detachment in Polymerase Chain Reaction–Positive Patients: A Single-Center Experience

To evaluate the clinical features, operative techniques, and surgical outcomes of patients who underwent surgery for acute retinal necrosis (ARN)-related retinal detachment (RD). Retrospective, longitudinal, consecutive case series. Patients with polymerase chain reaction-positive ARN presenting from 2011 to 2021 who underwent vitreoretinal surgery for ARN-related RD at our institution. Univariate, multivariate, and survival analyses were used to determine predictors of anatomic and functional outcomes. Single-surgery anatomic success rate, recurrent RD, and visual acuity (VA) at 1year. Thirty-four eyes of 34 patients (32.4% women, mean age, 45.1 ± 20.4 years) were included for analysis with a median follow-up of 2.5 years (interquartile range [IQR], 0.8-5.5 years). Presenting VA was 1.1±0.8 logarithm of the minimum angle of resolution (LogMAR) (Snellen ∼20/250). The median time from presentation to RD surgery was 1.7 months (IQR, 0.8-4.1 months), and the mean preoperative VA was 1.6 ± 0.8 LogMAR (Snellen ∼20/800). Small-gauge pars plana vitrectomy (PPV) with or without a scleral buckle (SB) was performed for all eyes with an overall single-surgery success rate of 63.6%, with no statistically significant differencesin visual/anatomic outcomes between PPV and PPV/SB cases. Silicone oil was used for tamponade in 33 (97.1%) cases and was removed in 10 (30.3%) with good anatomic and final functional outcomes (Snellen∼20/80). Independent predictors of recurrent RD included the female sex (hazard ratio, 8.38; 95% confidence interval, 2.03-34.68; P < 0.01) and zone 1 retinitis involvement at presentation (hazard ratio, 10.95; 95% confidence interval, 2.12-56.48; P < 0.01). The mean VA at 1 year (VA1year) and at the final follow-up both had a Snellen equivalent of 20/640 (P > 0.05 for both compared with preoperative VA, respectively). Eyes that achieved single-surgery success had VA1year of 20/200 versus hand movements in those with single-surgery failure (P < 0.01). On multivariate linear regression, younger age (P= 0.04) and better presenting VA (P<0.01) were both associated with better VA1year. Moderate single-surgery anatomic success can be achieved with modern vitreoretinal surgical techniques for ARN-related RD, although visual outcomes remain poor. Further studies investigating interventions for increasing single-surgery success rates, for the inflammatory complications of ARN, and for preventing ARN-related RD are needed.

Outcomes of 25-gauge pars plana vitrectomy alone with air tamponade for the management of rhegmatogenous retinal detachment with inferior breaks

BackgroundThis study was investigated the surgical outcomes of primary rhegmatogenous retinal detachment (RRD) with inferior retinal breaks (IRBs) that were repaired by 25-gauge pars plana vitrectomy (PPV) with air tamponade.MethodsThis retrospective review included 81 consecutive patients who had RRD with IRBs and underwent PPV with air tamponade in our hospital from January 2017 to January 2020. The main outcomes were single surgery anatomical success (SSAS) rate, postoperative best-corrected visual acuity (BCVA), and complications.ResultsThe patient population consisted of 29 women and 52 men (mean age, 52.12 years); the mean follow-up interval was 8.88 months. The mean number of affected quadrants was 1.65 (range, 1–4 quadrants) and the mean number of breaks was 3.25. A single break was present in 20 cases (24.7%); two to 10 breaks were present in 61 (75.3%) cases. The SSAS rate was 91.36% (74/81) and the final anatomical success rate was 96.30% (78/81). More than half of the patients had BCVA < 0.3 logarithm of the minimum angle of resolution at the last follow-up. Axial length and patient age were candidate risk factors for redetachment (axial length, p = 0.03; age, p = 0.002). Postoperative complications included macular epiretinal membrane formation in one patient, lens opacity in three patients, and clinically significant macular edema in one patient.ConclusionsPPV with air tamponade may be effective for the treatment of primary RRD with IRBs. Extensive preoperative discussion may be necessary for young patients and patients with particularly long axial length.

360-Degree laser retinopexy in primary vitrectomy for rhegmatogenous retinal detachment: factors associated with its use and impact on surgical outcomes

BackgroundTo determine patient and surgical factors associated with the use of 360-degree laser retinopexy during primary pars plana vitrectomy (PPV) ± scleral buckle (SB) for rhegmatogenous retinal detachment (RRD) and its impact on surgical outcomes.MethodsPatients who underwent PPV ± SB for repair of non-complex RRD at a single centre were included in this retrospective study. The primary outcome was single surgery anatomical success (SSAS). Secondary outcomes included visual acuity, epiretinal membrane formation, the presence of cystoid macular oedema, tonic pupil and corneal epithelial defects. Multiple logistic regression and multivariate regression was used.ResultsThe study included 192 cases, of which 130 received 360-degree laser. Worse preoperative logMAR visual acuity (P = 0.009), male sex (P = 0.060), higher PVR grades, supplemental SB (P = 0.0468) and silicone oil/C3F8 tamponade (P < 0.0001) were associated with 360-degree laser use. No significant associations between 360-degree laser and SSAS (P = 0.079), final logMAR visual acuity (P = 0.0623), ERM development (P = 0.8208), postoperative CMO (P = 0.5946), tonic pupil (P > 0.9999) or corneal epithelial defects (P = N/A) were found.Conclusions360-degree laser retinopexy during primary PPV ± SB for RRD was associated with more complex cases and more extensive operations. Even when accounting for this, there was no difference in surgical outcomes or complication rates.

Simultaneous Management of Retinal Detachment and Aphakia with Pars Plana Vitrectomy, Silicone Oil Tamponade and Retropupillary Iris-Claw Intraocular Lens Implantation in These Cases.

Marfan Syndrome is an autosomal dominant disease with multiple ocular abnormalities including ectopia lentis and a high incidence of rhegmatogenous retinal detachment (RRD). The management of RRD may be challenging in cases of aphakic patients with Marfan. To report on the management of four cases of simultaneous RRD and aphakia with vitrectomy, silicone oil tamponade, and retropupillary iris-claw intraocular lens (IOL) implantation in patients with Marfan that have been operated at the Jules-Gonin Eye Hospital between 2019 and 2020. Ages at presentation were 20, 30, 32, and 31 years, respectively. All patients had a history of extraction of a dislocated lens. None of the patients had a previous posterior vitrectomy. Two patients had records of previous measurements for IOL calculation by optical biometry (IOL Master, Carl Zeiss Meditec AG, Jena, Germany) about 1 year prior to the RRD development. In two cases, measurements for IOL calculation by optical biometry were based on the contralateral eye. All patients underwent 23 G vitrectomy, peripheral iridotomy, and retropupillary iris-claw IOL. No intraoperative complications were encountered. All patients had silicone oil tamponade, one of which required heavy silicone oil. Silicone oil was removed 3 months following primary surgery. Minimum follow-up was 1 year. The single surgery anatomic success rate was 100%. All patients had visual acuity of at least 0.8 at the last follow-up (1.25, 1.0, 0.8, and 0.8 respectively). The targeted refractive results were accurately achieved in all four cases postoperatively. One patient presented ocular hypertension 2 weeks after surgery due to presumed steroid response and was managed conservatively. None of the patients had silicone oil migration into the anterior chamber. Retropupillary iris-claw IOL implantation in cases of RRD and aphakia creates a barrier to tamponades from the posterior segment, effectively preventing them from entering the anterior segment of the eye. Therefore, the management of aphakia and retinal detachment with simultaneous vitrectomy and a retropupillary iris-claw IOL may be a successful strategy in reducing postoperative complications in patients with Marfan syndrome.

Management of uncomplicated rhegmatogenous retinal detachments: a comparison of practice patterns and clinical outcomes in a real-world setting.

To investigate practice patterns and clinical outcomes in the repair of uncomplicated rhegmatogenous retinal detachments (RRD) in a real-world setting over a 10-year period. We compared preferences for scleral buckling (SB), pars plana vitrectomy (PPV), PPV/SB, or pneumatic retinopexy (PR) over time, and examined the 1-year single surgery anatomic success (SSAS) and best-corrected visual acuity (BCVA) at a tertiary academic institution from 2008-2018. Eight hundred eight eyes had RRD repair between 2008-2011 (n = 240), 2012-2014 (n = 271), and 2015-2017 (n = 297). Compared to 2008-2011, PPV was preferred over SB in 2012-2014 (OR: 2.93; 95% CI: 1.86-4.63) and 2015-2017 (OR: 5.94; 95% CI: 3.76-9.38), and over PPV/SB in 2012-2014 (OR: 2.74; 95% CI: 1.65-4.56) and 2015-2017 (OR: 3.16; 95% CI: 31.96-5.12). PR was uncommonly utilized (<10%). Younger surgeons (graduating 2010-2017) favored PPV over SB when compared to older surgeons [graduating 1984-2000 (OR: 1.77; 95% CI: 1.18-2.65) and 2001-2009 (OR 1.73; 95% CI: 1.14-2.65)], but similarly selected PPV vs. PPV/SB as their older counterparts (p > 0.05). Compared to PPV, SSAS was higher with SB (OR: 1.53; 95% CI: 1.03-2.26) and PPV/SB (OR: 2.55; 95% CI: 1.56-4.17). One-year BCVA was markedly improved compared to baseline only for eyes that achieved SSAS (p < 0.001). Over the past 10 years, PPV has become the favored approach to repair uncomplicated RRD and this appears to be driven by younger surgeons' preferences. Given the superior long-term SSAS in SB and PPV/SB as compared to PPV, SB and PPV/SB should be more frequently considered when determining the appropriate repair strategy for uncomplicated RRD.

Vitrectomy versus Vitrectomy with Scleral Buckling in the Treatment of Giant Retinal Tear Related Retinal Detachments: An International Multicenter Study

To determine the practice pattern for treating giant retinal tear (GRT) related detachments, and their anatomic and visual outcomes with pars plana vitrectomy (PPV) with or without scleral buckling (SB). Retrospective cohort study. Eyes with GRT detachments repaired from 2008 to 2020 with at least 6 months of follow-up from 7 institutions in North and South America, Europe, and Asia. Eyes repaired using PPV versus PPV/SB were compared. Anatomic and functional outcomes. A comparable number of eyes underwent PPV (n= 101) and PPV/SB (n= 99). Except for history of developmental abnormalities, prior intraocular surgery, and lens status, no differences in baseline demographics, ocular characteristics, or intraoperative surgical adjuncts were observed. The overall single surgery anatomic success (SSAS) at 6 months and 1 year were similar between the groups (82.2% and 77.2% of PPV, and 87.9% and 85.7% of PPV/SB). When stratified by age, the 1-year SSAS rate was higher for PPV/SB (88.5%) than PPV (56.3%) (P= 0.03) for children <18 years. For both children and adults, the mean best-corrected visual acuity (BCVA) at baseline did not differ between the PPV and PPV/SB groups. However, for children, mean BCVA at 1 year was better in the PPV/SB than PPV groups (P= 0.001) while for adults, no difference was found between the 2 groups. The mean time to the first redetachment was 7.9 months in the PPV group and 5.5 months in the PPV/SB group (P= 0.8). Proliferative vitreoretinopathy was the most common cause for redetachment (70.4% of PPV and 93.8% of PPV/SB in redetached eyes; P= 0.1). Postoperative complications were also similar between the 2 groups, including ocular hypertension, epiretinal membrane, and cataract formation. PPV and PPV/SB are equally popular among surgeons globally for managing GRT detachments and have comparable anatomic and visual outcomes in adults. In children, PPV/SB is superior to PPV for anatomic and functional success at 1 year. In adults, the relief of traction by the GRT may reduce peripheral traction and obviate the need for an SB. However, in children, a supplemental SB can be beneficial as complete vitreous shaving and posterior hyaloid detachment, and postoperative positioning, are difficult in this group.

Impact of Coronavirus Disease 2019 Restrictions on Retinal Detachment: A Multicenter Experience

In this retrospective, multicenter study of 261 eyes (259 patients), patients who underwent rhegmatogenous retinal detachment repair during the coronavirus disease 2019 (COVID-19) post-lockdown period experienced an additional 22-day delay, leading to significantly more epiretinal membrane and proliferative vitreoretinopathy and lower single-surgery anatomic success rates. During lockdown, perfluoropropane gas was used more commonly, and pneumatic retinopexy was used more commonly in COVID-19–positive patients.

Repair of progressive retinal detachment complicating degenerative retinoschisis: surgical management and outcomes in phakic eyes

BackgroundDegenerative retinoschisis is a common condition defined by the splitting of the neurosensory retina that may rarely be associated with progressive retinal detachment (RD). Here, we aim to describe the anatomic and functional outcomes of surgical treatment of progressive symptomatic retinal detachment complicating degenerative retinoschisis (PSRDCR) using pars plana vitrectomy (PPV), scleral buckle (SB), or combined PPV/SB procedure.MethodsA retrospective chart review of patients with PSRDCR between Jan 1, 2008 and Dec 31, 2019 was conducted. Data regarding demographics, surgical approach, and anatomic/functional outcomes were collected.ResultsOf the 4973 charts with RD repair during the study period, 36 eyes (0.7%) had retinoschisis with RD. 18 eyes met inclusion criteria (0.4%). The median age was 54 years (range 18–74) and all eyes were phakic. All eyes had outer layer breaks (OLBs) and 16 eyes (89%) had identifiable inner layer breaks. All OLBs were posterior to the equator in charts where position was recorded (16 eyes). The single surgery anatomic success (SSAS) and final anatomical success rates were 66% (12/18) and 100%, respectively. Eyes treated with PPV/SB had an SSAS rate of 75% (9/12), while PPV and SB had SSAS rates of 66% (2/3) and 33% (1/3), respectively.ConclusionsPSRDCR is an exceedingly rare complication of degenerative retinoschisis associated with an SSAS rate lower than for uncomplicated rhegmatogenous RD. The majority of PSRDCR were repaired via combined PPV/SB in our study, and the rarity of this complication limits statistical support of an optimal surgical method in our and prior studies. The role of SB combined with PPV for PSRDCR requires further investigation.
