Project description:Existing surgical modes for retinal detachment are elaborate and extremely complex. We have treated 20 cases of rhegmatogenous retinal detachment with pneumatic retinopexy which is Iess time consuming and does not require hospitalization. After pneumatic retinopexy reattachment of retina was achieved in 15 (75%) eyes. In 2 eyes retinal reattachment was achieved after repeating intravitreal injection of sulphur hexafluoride gas. Remaining 3 eyes were secondarily treated with scleral buckle surgery. One case needed vitreoretinal surgery. In pneumatic retinopexy there is minimum tissue handling and functional results are good.

Project description:ImportancePneumatic 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.ObjectiveTo describe the clinical outcomes associated with RRD treated primarily with PR.Design, setting, and participantsIn 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.ExposuresData 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 measuresThe number of eyes that achieved single-operation success (SOS), defined as retinal reattachment without a subsequent retinal detachment surgery or repeated PR.ResultsOf 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 relevanceIn 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.

Project description:PURPOSE:To determine factors predictive of anatomic, visual, and financial outcomes after traditional and nontraditional primary pneumatic retinopexy (PR) for rhegmatogenous retinal detachment (RD). DESIGN:Retrospective interventional case series and cost comparison. METHODS:Participants: Total of 178 eyes (156 patients) with PR-repaired primary RD by a single surgeon at a clinical practice from January 2001 to December 2013 and followed for ≥1 year. The cohort had 2 subgroups: traditional (TPR) and nontraditional (NTPR) PR. MAIN OUTCOME MEASURES:Characteristics associated with best-corrected visual acuity (BCVA) and anatomic outcomes. Cost analysis and potential cost savings comparing PR to scleral buckle and vitrectomy. RESULTS:One hundred thirty-one of 178 eyes (73.5%) were successfully treated at 1 year (postoperative year 1): 72.8% (75/103) in TPR and 74.6% (56/75) in NTPR. Macula-off detachment (-0.44 logMAR, P < .001) and clock hours of RD (-0.84 logMAR, P < .001) correlated with improved BCVA; pseudophakia (0.26 logMAR, P = .002) and inferior retinal tears (0.62 logMAR, P = .009) correlated with worsening BCVA. Pseudophakia (-0.15, P = .03), inferior quadrant RD (-0.27, P < .001), and proliferative vitreoretinopathy (-0.68, P < .001) correlated with anatomic failure. Total average cost for TPR and NTPR was $1248.37 ± $882.11 and $1471.91 ± $942.84, respectively (P = .10). PR had a potential cost savings of 62% and 60.8% when compared to scleral buckle and vitrectomy, respectively. CONCLUSIONS:PR results in successful anatomic and visual outcomes in both TPR and NTPR repair of primary RD. Preoperative pseudophakia is associated with worse visual outcomes and less anatomic success. The cost of primary PR and subsequent procedures to achieve final anatomic success was not significantly different between TPR and NTPR, and supports the possible cost-effectiveness of expanded indications for PR.

Project description:ImportanceAlthough rhegmatogenous retinal detachment (RRD) repair techniques have high anatomical reattachment rates, there may be differences in various aspects of postoperative vision-related quality of life (VRQoL).ObjectiveTo explore the differences in various aspects of VRQoL between pneumatic retinopexy (PnR) and pars plana vitrectomy (PPV) following RRD repair.Design, setting, and participantsPost hoc exploratory analysis of the the Pneumatic Retinopexy vs Vitrectomy for the Management of Primary Rhegmatogenous Retinal Detachment Outcomes randomized clinical trial conducted between August 2012 and May 2017 at St Michael's Hospital, Toronto, Ontario, Canada. Patients with RRD with a single break or multiple breaks within 1 clock hour of detached retina in the superior 8 clock hours of the retina with any number, location, and size of retinal breaks or lattice degeneration in attached retina.Main outcomes and measuresDifferences in the 25-Item National Eye Institute Visual Function Questionnaire 12 subscale scores between the PnR and PPV groups at 6 months following RRD repair.ResultsA total of 160 patients were included in this analysis, with 81 patients (92%) and 79 patients (90%) in the PnR and PPV groups, respectively. The PnR group consisted of 32% women with a mean (SD) age of 60.9 (9.3) years, while the PPV group consisted of 38% women with a mean (SD) age of 60.3 (7.6) years. For the 152 patients with 6-month follow-up (75 patients in PnR [85%] and 77 patients in PPV [88%]), there was evidence for an association of PnR with superior vision-related functioning compared with PPV for several subscales. There were no differences between groups at 1 year. After adjusting for age, sex, baseline macular status, visual acuity in the nonstudy eye, and lens status, patients who underwent PnR had higher scores for distance activities (mean [SD] PnR, 88.7 [13.4]; PPV, 82.8 [17.1]; adjusted difference, 6.5; 95% CI, 1.6-11.4; P = .01), mental health (mean [SD] PnR, 84.3 [17.4]; PPV, 78.7 [21.1]; adjusted difference, 6.7; 95% CI, 0.4-13; P = .04), dependency (mean [SD] PnR, 96.1 [10.1]; PPV, 91.1 [18.6]; adjusted difference, 5.7; 95% CI, 0.6-10.8; P = .03), and peripheral vision (mean [SD] PnR, 91.6 [16.2]; PPV, 81.2 [24.4]; adjusted difference, 10.8; 95% CI, 4.3-17.4; P = .001) at 6 months.Conclusions and relevanceThese findings demonstrate that patients undergoing PnR for RRD report higher mental health scores and superior vision-related functioning scores in several subscales of the 25-Item National Eye Institute Visual Function Questionnaire during the first 6 months postoperatively compared with PPV.Trial registrationClinicalTrials.gov Identifier: NCT01639209.

Project description:PurposeThis study describes a novel surgical technique of fibrin glue-assisted retinopexy for rhegmatogenous retinal detachment (GuARD) without oil or gas tamponade after pars plana vitrectomy (PPV).MethodsThis pilot clinical trial included five eyes of five patients with rhegmatogenous retinal detachments (RD). A complete PPV was done in all cases followed by fluid-air exchange, laser photocoagulation around the break/s, and application of 0.1-0.2 mL of fibrin glue. No air, long-acting gas or silicone oil was used subsequently. No specific postoperative positioning was prescribed. The primary outcome measure was efficacy of the procedure defined as successful anatomical retinal reattachment. Secondary outcome measures were postoperative improvement in best corrected visual acuity (BCVA) and complications.ResultsThe median age of patients was 55 (range: 36-61 years) years and median duration of symptoms was 15 (range: 7-60) days. All eyes were pseudophakic, four eyes had inferior and one eye had total RD. Successful retinal reattachment was achieved in all (100%) cases and was maintained at the end of 3-8 months of follow-up. The median BCVA improved from 20/100 preoperatively to 20/80 at 1-week and 20/50 at 1-month postoperatively. None of the eyes had any postoperative complications such as elevated intraocular pressures or unexpected inflammation.ConclusionThe findings of this study suggest that GuARD is a promising technique for treatment of rhegmatogenous RD that may allow early visual recovery while avoiding the problems of gas or oil tamponade and obviating the need of postoperative positioning.

Project description:ImportanceIn-office suprachoroidal viscopexy (SCVEXY) is a minimally invasive technique for rhegmatogenous retinal detachment (RRD) repair that can be performed with no incision, no tamponade agent, and no positioning requirements. This technique has the potential to be a step forward in the armamentarium to treat RRDs.ObjectiveTo describe in-office SCVEXY for RRD repair.Design, setting, and participantIn this single-case report with short follow-up, a man in his 50s with pseudophakia and recent visual loss presented to St Michael's Hospital, Unity Health Toronto, with a fovea-off RRD in the right eye, extending from 6 to 10 o'clock, with no visible causative retinal break.ExposureInjection of suprachoroidal sodium hyaluronate, 1%, in the region of the suspected break, using a 30-gauge needle with a custom-made guard that exposed only 1 mm of the needle.Main outcome and measuresAbility to perform in-office SCVEXY and to obtain a visible choroidal indentation.ResultsAfter the procedure, a dome-shaped choroidal convexity was present in the superior temporal area. The patient achieved macular reattachment in less than 24 hours with no postoperative abnormalities, such as outer retinal folds, residual subfoveal fluid, or retinal displacement, with rapid recovery of the outer retinal bands on optical coherence tomography. The optical coherence tomography scans acquired in the area of the choroidal convexity demonstrated the location of the viscoelastic material in the suprachoroidal space. Laser retinopexy was applied in the suspected region of the retinal tear, and the patient was able to resume normal activity immediately after the procedure with no restrictions.Conclusions and relevanceSuprachoroidal viscopexy is feasible as an in-office technique to create a temporary choroidal buckle for RRD repair. It is a minimally invasive procedure with the potential to maximize anatomical outcomes of integrity and postoperative functional outcomes in RRD because its mechanism of action does not require drainage of subretinal fluid or intraocular gas tamponade. Nevertheless, this was a single-case report with short follow-up, which limits the ability to determine the procedure's benefits, potential adverse events, failure rates, and best-case selection. Further work is required to refine the procedure and assess its efficacy and safety.

Project description:PurposeTo describe presenting clinical features and surgical techniques that are associated with successful surgical repair of pediatric rhegmatogenous retinal detachment (RRD).DesignRetrospective interventional case series.ParticipantsTwo hundred twelve eyes of 191 patients 0 to 18 years of age undergoing surgical repair for RRD between 2001 and 2015 with a minimum follow-up of 3 months.MethodsPatients were divided into 3 age groups (0-6 years, 7-12 years, and 13-18 years) and comparisons were made using bivariate and multivariate generalized estimating equation models. A mixed means model was used to examine visual acuity in each age group over time.Main outcome measuresComplete reattachment of the retina at final follow-up.ResultsOf 212 eyes, 166 (78%) achieved total reattachment at final follow-up. Mean follow-up was 36.3 months. Rhegmatogenous retinal detachment associated with Stickler syndrome was more likely to occur in the younger cohorts (odds ratio [OR], 0.45; 95% confidence interval [CI], 0.22-0.91), whereas RRD associated with blunt trauma was more likely to occur in the oldest cohort (OR, 2.3; 95% CI, 1.2-4.4). Subtotal RRD was more likely to be repaired successfully than total RRD (OR, 3.6; 95% CI, 1.5-8.4; P = 0.0100), and eyes with previous vitreoretinal surgery were less likely to undergo successful repair (OR, 0.30; 95% CI, 0.12-0.78; P = 0.0258). There was no significant difference between age groups in the rate of surgical success (P = 0.55). There was a significantly higher success rate with primary scleral buckle (SB; 63%; OR, 2.2; 95% CI, 1.1-4.5) and combined SB plus pars plana vitrectomy (PPV; 68%; OR, 2.3; 95% CI, 1.1-5.1) compared with PPV alone (51%).ConclusionsMost pediatric patients with RRD achieved complete reattachment with surgery. Success was more common in patients with a subtotal RRD at presentation. Previous vitreoretinal surgery was a risk factor for failure. Younger patients were more likely to demonstrate RRD involving the macula, but there was no difference between age groups in successful reattachment at final follow-up. Primary PPV showed a lower rate of success than SB or combined SB plus PPV.

Project description:Rhegmatogenous retinal detachment (RRD) is an ophthalmic emergency, which usually requires prompt surgery to prevent further detachment and restore sensory function. Although several individual factors have been suggested, a systems level understanding of molecular pathomechanisms underlying this severe eye disorder is lacking. To address this gap in knowledge we performed the molecular level systems pathology analysis of the vitreous from 127 patients with RRD using state-of-the art quantitative mass spectrometry to identify the individual key proteins, as well as the biochemical pathways contributing to the development of the disease. RRD patients have specific vitreous proteome profiles compared to other diseases such as macular hole, pucker, or proliferative diabetic retinopathy eyes. Our data indicate that various mechanisms, including glycolysis, photoreceptor death, and Wnt and MAPK signaling, are activated during or after the RRD to promote retinal cell survival. In addition, platelet-mediated wound healing processes, cell adhesion molecules reorganization and apoptotic processes were detected during RRD progression or proliferative vitreoretinopathy formation. These findings improve the understanding of RRD pathogenesis, identify novel targets for treatment of this ophthalmic disease, and possibly affect the prognosis of eyes treated or operated upon due to RRD.

Project description:The study aimed at a quantitative evaluation of macular vasculature after primary repair of rhegmatogenous retinal detachment (RRD) in correlation with the elapsed postoperative time. Optical coherence tomography angiography (OCT-A) was performed in 66 eyes of 33 patients in a retrospective case-control study: superficial and deep retinal vessel density (VD) of the whole image, fovea, parafovea, non-flow area, and foveal avascular zone (FAZ) were measured. Data of eyes with RRD were compared to the healthy fellow eyes in 3 groups according to the elapsed time after surgery: RD1: 6-12 months (n = 10), RD2: 1-2 years (n = 10), and RD3: 2-10 years (n = 13). In RD1 VD was significantly lower in the superficial parafoveal, deep parafoveal, and deep whole area compared to the fellow eyes. In RD3 VD was significantly lower in the superficial fovea, parafovea, whole image, and deep fovea, the non-flow area was significantly enlarged. OCT-A demonstrated a significant reduction in the superficial and deep regions of the macular vasculature after the repair of RRD. The deep area is more affected in the early postoperative period and the superficial region and the extent of the non-flow area are more involved after a longer postoperative time.

Project description:PurposeVarious profibrotic and proinflammatory cytokines have been found upregulated in uncomplicated primary retinal detachment (pRD), but without providing a uniform picture. Here, we compare the cyto- and chemokine profiles in pRD with and without proliferative vitreoretinopathy (PVR) in an attempt to unravel relevant differences not in single cytokines, but in the cytokine profiles at diagnosis.MethodsUndiluted vitreous fluid (VF) was obtained at the beginning of surgery from 174 eyes with pRD without relevant PVR (maximally grade B; group 1; n = 81) and with moderate or advanced PVR requiring a gas tamponade (group 2; n = 49) or silicon oil filling (group 3; n = 44). VF of eyes undergoing macular hole (MH) surgery served as controls (group 4; n = 26). Forty-three cytokines were quantified in parallel using a multiplex cytokine analysis system (Bioplex). For all comparisons we applied Holm's correction to control for multiple comparisons.Results44.9% of group 2 eyes presented grade C1 and 55.1% C2-C3, whereas 86.4% of group 3 eyes exhibited a PVR grade of C2-D. CCL19 was the only cytokine that displayed higher concentrations in the vitreous of eyes with PVR C1 compared to lower PVR grades. Eyes with PVR C2-D showed higher levels of CCL27, CXCL6, IL4, IL16, CXCL10, CCL8, CCL22, MIG/CXCL9, CCL15, CCL19, CCL 23 and CXCL12 compared to controls. Interestingly, no difference of cytokine levels was detected between C1 and C2-D PVR.ConclusionsCCL19 may represent a potential biomarker for early PVR progression that holds promise for future diagnostic and therapeutic applications.
