Effect of deprivation and ethnicity on primary macula-on retinal detachment repair success rate and clinical outcomes: A study of 568 patients
Ontology highlight
ABSTRACT: Purpose
Socio-economic deprivation and ethnic variation have been frequently linked to poorer health outcomes. We collected a large series of primary macula-on rhegmatogenous retinal detachment (RRD) cases and analysed the effect of socio-economic deprivation and ethnicity on both six-month retinal re-detachment rate and visual outcomes. Materials and methods
Retrospective consecutive case series of 568 patients attending Birmingham and Midlands Eye Centre from January 2017–2020. Multiple Indices of Deprivation (IMD) deciles were used for deprivation status and split to two groups: IMD-A (Decile 1–5) and IMD-B (Decile 6–10). The two largest subgroups of ethnicities were compared, White and South Asians (SA). Results
We report an overall retinal re-detachment rate of 8.5%. IMD-A re-detached significantly more than IMD-B (11.2% vs 6.0% respectively, p = 0.034). No statistical significance was found between White and SA re-detachment rate (9.1% and 5.6% respectively, p = 0.604). SA median age significantly lower at 49 years (IQR: 37–61) compared to White patients at 57 years (IQR: 50–65) (p = <0.001). IMD-A median age of 55 years (IQR: 46–64) was significantly lower to IMD-B median age of 58 years (IQR: 51–65) (p = 0.011). No differences in final visual outcomes were detected across all groups. Conclusion
We demonstrated an increased retinal re-detachment rate in our more deprived patients according to IMD and a younger cohort of SA compared to White ethnicity. Further prospective studies are required to demonstrate the link between socio-economic deprivation and surgical success.

Project description:PurposeTo find predictive markers for the visual potential in optical coherence tomography (OCT) one month after surgical repair of macula-involving rhegmatogenous retinal detachment (miRD) with and without internal limiting membrane (ILM) peeling.MethodsThis retrospective single-center, single-surgeon cohort study included 74 patients who underwent pars plana vitrectomy (PPV) for primary miRD between January 2013 and August 2020 with follow-up examinations for at least 6 months. Patients developing recurrent detachments, media opacities, or with an axial length over 27 mm were excluded from the analysis. LogMAR visual (VA) and LogRAD reading acuity (RA) ± standard deviation (SD), and OCT measurements 6 months after surgery were compared to OCT and VA measurements one month after surgery using multiple linear regression analysis for predictions.ResultsVA increased from 0.34 ± 0.25 at one month to 0.22 ± 0.21 after 6 months [p < 0.001; effect size = -0.662, 95% confidence interval (CI): -(0.99-0.33)]. The continuity of the external limiting membrane (ELM) and ellipsoid zone (EZ) increased between 1 and 6 months. Subfoveal ELM integrity after one month predicted VA [adjusted R2 of 8.0%, F(2, 71) = 4.17, p = 0.018] and RA [adjusted R2 of 29%, F(2, 27) = 6.81, p = 0.002] after 6 months. EZ integrity had a less pronounced predictive effect on VA and RA. ELM integrity after 1 month correlated with better reading acuity after 6 months (p = 0.016).ConclusionVA and morphological OCT parameters improve between 1 and 6 months after surgery for miRD. The grade of ELM is a better predictor for RA than for VA, explaining more variance.

Project description:PurposeTo investigate the thickness of retinal layers and association with final visual acuity using spectral-domain optical coherence tomography (SD-OCT) in macular area of macula-off rhegmatogenous retinal detachment (RRD) patients after a successful macular re-attachment.MethodsIn retrospective study, a total 24 eyes with macula-off RRD were enrolled. All patients underwent vitrectomy to repair RRD. Outer plexiform layer (OPL), outer nuclear layer (ONL), photoreceptor layer (PR), retinal pigment epithelium (RPE) thicknesses were measured by the Spectralis (Heidelberg Engineering, Heidelberg, Germany) SD-OCT with automated segmentation software. The relationship between the thicknesses of each retinal layer and postoperative logarithm of the minimum angle of resolution scale (LogMAR) visual acuity was analyzed.ResultsOPL and RPE thicknesses were not significantly different between the retinal detachment eyes and fellow eyes (P = 0.839, 0.999, respectively). The ONL and photoreceptor thickness were significantly thinner in the retinal detachment eyes (P <0.001 and 0.001, respectively). In the univariate regression analysis, preoperative best corrected visual acuity (BCVA), ONL thickness and photoreceptor thickness showed association with the postoperative BCVA (P = 0.003, <0.001 and 0.024, respectively). In final multiple linear regression model, ONL thickness was the only variable significantly associated with postoperative BCVA (P = 0.044).ConclusionsSegmented ONL and photoreceptor thickness of retinal detachment eyes were significantly thinner than fellow eyes. Segmental analysis of the retinal layer in macular region may provide valuable information for evaluation RRD. And ONL thickness can be used as a potential biomarker to predict visual outcome after RRD repair.

Project description:PurposeTo evaluate the reliability and reproducibility of visual function assessments for patients with macula-off rhegmatogenous retinal detachment (RRD).MethodsThis prospective study included patients with unilateral macula-off RRD of <10-day duration successfully treated with a single, uncomplicated surgery at least 1 year following repair. Visual function assessments were performed at time of enrollment and 1 month later. Testing included Early Treatment Diabetic Retinopathy Study (ETDRS) best-corrected visual acuity (BCVA), low-luminance visual acuity (LLVA), low-contrast visual acuity (VA) 2.5% and 5%, contrast sensitivity assessment with Mars and Gabor patches, reading speed (acuity, speed, and critical print size), color vision testing (protan, deutan, and tritan), and microperimetry. Spectral-domain ocular coherence tomography (SD-OCT) was performed. Paired t-statistics were used to compare values between visits and between the study and fellow eyes.ResultsFourteen patients (9 male, 5 female) with a mean age of 69 years at time of surgery were evaluated. Correlation coefficients across the two visits were highest for ETDRS BCVA (0.97), tritan color vision testing (0.96), and low-contrast VA 5% (0.96), while the average t-statistic was largest for low-luminance deficit (4.2), ETDRS BCVA (4.1), and reading speed critical print size (3.7). ETDRS BCVA did not correlate with SD-OCT findings.ConclusionsETDRS BCVA can be considered a highly reliable and reproducible outcome measure. LLVA, protan color discrimination, contrast sensitivity, and reading speed may be useful secondary outcome measures.Translational relevanceThis study provides guidance on the selection of visual function outcome measures for clinical trials of patients with macula-off 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:ObjectiveTo evaluate costs and treatment benefits of rhegmatogenous retinal detachment (RD) repair.DesignA Markov model of cost-effectiveness and utility.ParticipantsThere were no participants.MethodsPublished clinical trials (index studies) of pneumatic retinopexy (PR), scleral buckling (SB), pars plana vitrectomy (PPV), and laser prophylaxis were used to quantitate surgical management and visual benefits. Markov analysis, with data from the Center of Medicare and Medicaid Services, was used to calculate the adjusted costs of primary repair by each modality in a hospital-based and ambulatory surgery center (ASC) setting.Main outcome measuresLines of visual acuity (VA) saved, cost of therapy, adjusted cost of therapy, cost per line saved, cost per line-year saved, and cost per quality-adjusted life years (QALY) saved.ResultsIn the facility, hospital surgery setting, weighted cost for PR ranged from $3726 to $5901 depending on estimated success rate of primary repair. Weighted cost was $6770 for SB, $7940 for PPV, and $1955 for laser prophylaxis. The dollars per line saved ranged from $217 to $1346 depending on the procedure. Dollars per line-year saved ranged from $11 to $67. Dollars per QALY saved ranged from $362 to $2243. In the nonfacility, ASC surgery setting, weighted cost for PR ranged from $1961 to $3565 depending on the success rate of primary repair. The weighted costs for SB, PPV, and laser prophylaxis were $4873, $5793, and $1255, respectively. Dollars per line saved ranged from $139 to $982. The dollars per line-year saved ranged from $7 to $49, and the dollars per QALY saved ranged from $232 to $1637.ConclusionsTreatment and prevention of RD are extremely cost-effective when compared with other treatment of other retinal diseases regardless of treatment modality. Retinal detachment treatment costs did not vary widely, suggesting that providers can tailor patient treatments solely on the basis of optimizing anticipated results because there were no overriding differences in financial impact.

Project description:ImportanceA lack of consensus exists with regard to the optimal positioning regimen for patients after macula-involving retinal detachment (RD) repair.ObjectiveTo evaluate the effect of face-down positioning vs support-the-break positioning on retinal displacement and distortion after macula-involving RD repair.Design, setting, and participantsA prospective 6-month single-masked randomized clinical trial was conducted at a multicenter tertiary referral setting from May 16, 2016, to May 1, 2018. Inclusion criteria were fovea-involving rhegmatogenous RD; central visual loss within 14 days; patients undergoing primary vitrectomy and gas surgery, under local anesthetic; patients able to give written informed consent; and 18 years old and older. Analysis was conducted following a modified intention-to-treat principle, with patients experiencing a redetachment or failure to attach the macula being excluded from analysis.InterventionsParticipants were randomized 1:1 to receive face-down positioning or support-the-break positioning for a 24-hour period postoperatively. Positioning compliance was not monitored.Main outcomes and measuresThe proportion of patients with retinal displacement on autofluorescence imaging at 6 months postoperatively. Secondary outcomes included proportion of patients with displacement at 2 months; amplitude of displacement at 2 and 6 months; corrected Early Treatment Diabetic Retinopathy Study visual acuity; objective Distortion Scores; and quality of life questionnaire scores at 6 months.ResultsOf the 262 randomized patients, 239 were analyzed (171 male [71.5%]; mean [SD] age, 60.8 [9.8] years). At 6 months, retinal displacement was detected in 42 of 100 (42%) in the face-down positioning group vs 58 of 103 (56%) in the support-the-break positioning group (odds ratio, 1.77; 95%CI, 1.01-3.11; P = .04). The degree of displacement was lower in the face-down group. Groups were similar in corrected visual acuity (face-down, 74 letters vs support-the-break, 75 letters), objective D Chart Distortion Scores (range: 0, no distortion to 41.6, severe distortion; with face-down at 4.5 vs support-the-break at 4.2), and quality of life scores (face-down 89.3 vs support-the-break 89.0) at 2 and 6 months. Retinal redetachment rate was similar in both groups (face-down group, 12.2% and support-the-break group, 13.7%). Retinal folds were less common in the face-down positioning group vs the support-the-break positioning group (5.3% vs 13.5%, respectively; odds ratio, 2.8; 95% CI, 1.2-7.4; P = .03). Binocular diplopia was more common in the support-the-break group compared with the face-down positioning group (7.6% vs 1.5%, respectively; odds ratio, 5.3; 95% CI, 1.3-24.6; P = .03). Amplitude of displacement was associated with worse visual acuity (r = -0.5; P < .001) and distortion (r = 0.28; P = .008).Conclusions and relevanceIn this study, findings suggest that face-down positioning was associated with a reduction in the rate and amplitude of postoperative retinal displacement after macula-involving RD repair and with a reduction in binocular diplopia. No association was found with visual acuity or postoperative distortion.Trial registrationClinicalTrials.gov Identifier: NCT02748538.

Project description:PurposeWe describe the outcome of a 23-year-old man undergoing vitreoretinal surgery for a macula-off rhegmatogenous retinal detachment secondary to a giant retinal tear.MethodsPatient underwent combined 25- gauge 3-port pars plana vitrectomy with scleral buckle, perfluorocarbon liquid, and perfluoropropane gas tamponade. During surgery, triamcinolone inadvertently entered the subretinal space and was retained.ResultsThe subretinal triamcinolone deposits spontaneously absorbed over a 2-month period. No adverse sequelae were associated with this complication.ConclusionThis may support avoiding aggressive mechanical removal of iatrogenic subretinal triamcinolone in the context of retinal detachment repair.

Project description:PurposeTo compare baseline levels of exploratory biomarkers in the vitreous fluid of patients with primary retinal detachment who subsequently develop proliferative vitreoretinopathy (PVR) versus those who do not.MethodsIn this exploratory case-control study, we evaluated the baseline protein biomarker levels from a biobank containing the vitreous fluid of patients who had undergone primary pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment. Undiluted samples were collected at the time of PPV and stored at -80°C. Samples from 13 patients who developed PVR within 6 months (PVR group) and 13 age- and gender-matched controls who did not develop PVR (control group) were included. Protein abundance levels were evaluated using a proximity extension assay, and a confirmatory enzyme-linked immunosorbent assay (ELISA) was used to measure the concentration of vimentin.ResultsBaseline vimentin (Normalized Protein eXpression [NPX], 8.6 vs. 6.4, P < 0.0001) and heme oxygenase 1 (NPX 8.9 vs. 7.0, P < 0.001) levels were found to be elevated in vitreous fluid of patients who subsequently developed PVR compared to those who did not. Confirmatory analysis using ELISA demonstrated mean vimentin concentrations of 7254 vs. 2727 ng/mL in the PVR versus control groups (P = 0.0152). The odds ratio for developing PVR was 14 (confidence interval, 1.4-168; P = 0.03), assuming a baseline vimentin threshold of 7500 ng/mL.ConclusionsVimentin is an intermediate filament protein expressed by retinal glial cells, and our data combined with prior evidence suggest that it may serve as an early vitreous biomarker for subsequent PVR formation and reactive gliosis. Furthermore, we found, for the first time, elevated baseline levels of heme oxygenase 1, a measurable indicator of oxidative stress.Translational relevanceOur positive findings could impact clinical care for retinal detachment patients by facilitating risk stratification for targeted interventions or closer monitoring in those at the highest risk of developing PVR.

Project description:We aimed to evaluate the neuroprotective efficacy of rasagiline in pseudophakic patients who had surgery for macula-off rhegmatogenous retinal detachment (RRD). This was a 6-month, prospective, randomized, double-blind, placebo-controlled pilot study. Patients presenting with acute macula-off RRD were recruited and randomized 1:1 to receive rasagiline 1?mg/day or placebo for 7 days. Best-corrected visual acuity (BCVA) and optical coherence tomography were acquired 1 day before as well as 2 days, 3 weeks, 3 months and 6 months after surgery. We screened 26 patients with RRD whereof 23 were eventually included and randomized. The primary outcome was final BCVA. Secondary outcomes included central retinal thickness (CRT) and adverse events (AE). We evaluated photoreceptor cells (prc) recovery through morphological measurements. The baseline characteristics were comparable between groups. BCVA significantly improved in both groups (letters gained: rasagiline 61.5?±?18.1 vs placebo 55.3?±?29.2, p?=?0.56), but no significant inter-group difference was found at any visit. CRT was stable 3 weeks after surgery onwards, with no inter-group difference. No treatment-emergent AE occurred. Significant prc restoration was observed from 3 weeks to 6 months after surgery, without inter-group difference at either visit. Ellipsoid zone integrity (??=?0.517, p?=?0.008) and foveal bulge (??=?0.387, p?=?0.038) were significant predictors of good final BCVA. In conclusion, perioperative oral treatment with rasagiline 1?mg/day for 7 days did not show significant benefits on visual or anatomical outcomes in macula-off RRD patients.

Project description:PurposeTo investigate the effects of internal limiting membrane (ILM) peeling on visual acuity (VA) after rhegmatogenous retinal detachment (RRD) surgery.MethodsThis retrospective analysis examined the medical records of patients with RRD who underwent vitrectomy at 26 institutions. To detect prognostic factors of VA at 6 months postoperatively (post-VA), multivariate linear regression was performed with post-VA as the objective variable; ILM peeling, sex, age, preoperative VA (pre-VA), intraocular pressure, axial length, duration of RRD, and cataract surgery served as explanatory variables. Recurrence of RRD and epiretinal membrane formation within 6 months postoperatively were compared between groups of patients with and without ILM peeling, among patients with macula-on and macula-off RRD.ResultsThe inclusion criteria were met by 523 eyes with a macula-on RRD and 364 eyes with a macula-off RRD. ILM peeling was performed in 85 eyes with a macula-on RRD and 57 eyes with a macula-off RRD. In eyes with a macula-on RRD, ILM peeling did not affect post-VA (p = 0.72). Vitrectomy without cataract surgery and poor pre-VA were significantly associated with poor post-VA (p = 0.01 and p < 0.001, respectively). In eyes with a macula-off RRD, ILM peeling, long duration of RRD, and poor pre-VA were significantly associated with poor post-VA (p = 0.037, p = 0.007, and p < 0.001, respectively). Recurrence of RRD and epiretinal membrane formation were similar between groups of patients with and without ILM peeling, among patients with macula-on and macula-off RRD. Retina sensitivity was not evaluated by microperimetry.ConclusionILM peeling did not affect post-VA in eyes with a macula-on RRD, whereas post-VA was worse in eyes with ILM peeling than in eyes without peeling, among eyes with a macula-off RRD.
