RESUMO
PURPOSE: To assess long-term re-detachment rates of the Pneumatic Retinopexy versus Vitrectomy for the Management of Primary Rhegmatogenous Retinal Detachment Outcomes Randomized Trial (PIVOT). DESIGN: Randomized controlled trial. SUBJECTS: PIVOT trial participants METHODS: This 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 MEASURES: Long-term re-detachment rates for pneumatic retinopexy versus ppv following RRD repair. RESULTS: 61 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. CONCLUSION: There 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.
RESUMO
BACKGROUND: The purpose of the study is to compare visual acuity, complications and outer retinal integrity following subretinal fluid (SRF) drainage from the peripheral retinal breaks (PRBs) versus posterior retinotomy (PR) versus perfluorocarbon liquid (PFCL) for macula-off rhegmatogenous retinal detachments (RRDs) at 2 years post-surgery. METHODS: Retrospective analysis of 300 consecutive patients with primary RRD undergoing 23-gauge pars plana vitrectomy with SRF drainage through (1) PRB (n=100), (2) PR (n=100) or (3) with PFCL (n=100). Primary outcomes were visual acuity (best-corrected visual acuity (BCVA)) and complications (cystoid macular oedema (CMO) and epiretinal membrane (ERM)). Secondary outcomes were discontinuity of the external limiting membrane (ELM), ellipsoid zone (EZ) and interdigitation zone (IDZ) at 2 years post-surgery. RESULTS: Mean (±SD) logMAR BCVA at 24 months was better in the PRB compared with PR and PFCL, with PFCL having the worst BCVA (PRB 0.5±0.6; PR 0.7±0.5; PFCL 0.9±0.7, p=0.001). CMO was higher with PFCL (PRB 29.7%; PR 30.2%; PFCL 45.9%, p=0.0015) and ERM formation was higher in PR (PRB 62.6%; PR 93.0%; PFCL 68.9%, p=0.002). There were no differences in ELM or EZ discontinuity. However, IDZ discontinuity was higher in PFCL (PRB 34%; PR 27%; PFCL 46%, p=0.002) at 2 years. CONCLUSIONS: Visual acuity was worse and discontinuity of the IDZ and CMO was greater in eyes with PFCL-assisted drainage compared with PRB or PR. Drainage technique may impact long-term visual acuity and photoreceptor integrity.

PURPOSE: To compare foveal avascular zone (FAZ) geometric indices using optical coherence tomography angiography (OCTA) in pneumatic retinopexy (PnR) versus pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD). FAZ morphology was assessed as a possible imaging feature of retinal displacement. METHODS: This ALIGN post hoc analysis included primary fovea-off RRDs that underwent successful PnR or PPV, and performed OCTA, and fundus autofluorescence at (FAF) 3 months postoperatively at St. Michael's Hospital, Toronto, Canada. FAZ area (mm 2 ), axial ratio, circularity, and roundness were measured, and FAF images were assessed for retinal displacement. RESULTS: Seventy-two patients were included, 78% (56/72) were male mean age was 60 ± 9 years, and 60% (43/72) were phakic. Sixty-five percent (47/72) and 35% (25/72) underwent PnR and PPV, respectively. The mean baseline logarithm of the minimum angle of resolution visual acuity was 1.49 ± 0.76. FAZ circularity was lower after PPV (0.629 ± 0.120) versus PnR (0.703 ± 0.122); P = 0.016. Sixty-six patients had gradable FAF images. Retinal displacement was present in 29% (19/66), 84.2% (16/19) of which had displacement in the macula. FAZ circularity was lower in eyes with displacement in the macula (0.613 ± 0.110) versus those without displacement (0.700 ± 0.124); P = 0.015. There was a moderate negative correlation between 12-month aniseikonia and FAZ circularity(r = -0.262; P = 0.041). CONCLUSION: FAZ circularity was lower after PPV and in eyes with retinal displacement in the macula. Circularity was negatively correlated with 12-month aniseikonia scores. FAZ circularity may be another imaging feature to consider postoperatively after RRD repair.

PURPOSE: To evaluate the role of en face OCT as a diagnostic tool for the detection of persistent subretinal fluid (PSRF) and outer retinal folds (ORFs) after successful rhegmatogenous retinal detachment (RRD) repair. DESIGN: Observational post hoc analysis of 2 prospective surgical trials. PARTICIPANTS: All patients with gradable (signal strength ≥ 5 and no segmentation error) 6 × 6-mm2 macular cube scans obtained using spectral-domain OCT (Carl Zeiss Meditec) between 1 and 2 months after surgery were included in this study. METHODS: The scans were assessed for the presence or absence of PSRF or ORFs using en face OCT and cross-sectional B scans by 2 masked graders, with any disagreements adjudicated by a third senior masked grader. MAIN OUTCOME MEASURES: The sensitivity, specificity, and predictive accuracy (using area under the curve [AUC]) of en face OCT were compared with those of cross-sectional OCT, which is considered the gold standard. RESULTS: Two hundred twenty-three patients were included in this study. The Cohen kappa between the graders in the diagnosis of PSRF and ORFs using en face OCT was 0.84 and 0.86, respectively. The sensitivity of en face OCT was 100% (95% confidence interval [CI], 100%-100%) in the diagnosis of PSRF and 98.8% (95% CI, 96.5%-101.1%) in the diagnosis of ORFs. Similarly, the specificity of en face OCT was 98.7% (95% CI, 96.8%-100.5%) and 84.2% (95% CI, 78.1%-90.2%) in the diagnosis of PSRF and ORFs, respectively. The AUC was 0.99 for PSRF and 0.91 for ORFs. CONCLUSIONS: En face OCT has good sensitivity, specificity, and predictive accuracy (using AUC) in the diagnosis of PSRF and ORFs. En face OCT is an efficient screening tool for postoperative anatomic abnormalities, such as PSRF and ORFs, after RRD repair.

PURPOSE: To assess the incidence of persistent subfoveal fluid (PSFF) in pneumatic retinopexy (PnR) versus pars plana vitrectomy (PPV) following rhegmatogenous retinal detachment (RRD) repair and to determine its association with functional outcomes. METHODS: Posthoc analysis of the PIVOT randomised trial. Eyes with gradable en face and cross-sectional spectral-domain optical coherence tomography (SD-OCT) scans at 1-2 months postoperatively were included. Primary outcome was the proportion of patients with PSFF following PnR versus PPV at 1-2 months postoperatively. Secondary outcomes included association of PSFF with Early Treatment Diabetic Retinopathy Study (ETDRS) letter score at 3, 6 and 12 months and metamorphopsia score (MCHARTs) at 12 months. RESULTS: Of 176 participants enrolled in PIVOT, 158 (89.8%) had gradable SD-OCT scans. Intergrader agreement was 0.870 (Cohen's kappa). The incidence of PSFF was 16% (13/81) following PnR and 10.4% (8/77) following PPV (p=0.298; OR=1.65, 95% CI 0.64 to 4.23). Median ETDRS score at 3 months postoperatively between eyes with and without PSFF was 71 (IQR=58-78) and 78 (IQR=70-84), respectively (difference=7 letters, p=0.037), with no significant difference at subsequent 6-month and 12-month visits. Median metamorphopsia scores in patients with versus without PSFF were: horizontal: 0.1 (IQR=0-0.3) vs 0 (IQR=0-0.2) (difference=0.1, p=0.228) and vertical: 0.25 (IQR=0-0.4) vs 0 (IQR=0-0.2) (difference=0.25, p=0.148), respectively. CONCLUSIONS: There was no significant difference in the incidence of PSFF in eyes undergoing PnR versus PPV for RRD. The presence of PSFF at 1-2 months postoperatively was associated with worse ETDRS letter score at 3 months, but there was no difference at 1 year. TRIAL REGISTRATION NUMBER: NCT01639209.
RESUMO
OBJECTIVE: High cereal fiber and low-glycemic index (GI) diets are associated with reduced cardiovascular disease (CVD) risk in cohort studies. Clinical trial evidence on event incidence is lacking. Therefore, to make trial outcomes more directly relevant to CVD, we compared the effect on carotid plaque development in diabetes of a low-GI diet versus a whole-grain wheat-fiber diet. RESEARCH DESIGN AND METHODS: The study randomized 169 men and women with well-controlled type 2 diabetes to counseling on a low GI-diet or whole-grain wheat-fiber diet for 3 years. Change in carotid vessel wall volume (VWV) (prespecified primary end point) was assessed by MRI as an indication of arterial damage. RESULTS: Of 169 randomized participants, 134 completed the study. No treatment differences were seen in VWV. However, on the whole-grain wheat-fiber diet, VWV increased significantly from baseline, 23 mm3 (95% CI 4, 41; P = 0.016), but not on the low-GI diet, 8 mm3 (95% CI -10, 26; P = 0.381). The low-GI diet resulted in preservation of renal function, as estimated glomerular filtration rate, compared with the reduction following the wheat-fiber diet. HbA1c was modestly reduced over the first 9 months in the intention-to-treat analysis and extended with greater compliance to 15 months in the per-protocol analysis. CONCLUSIONS: Since the low-GI diet was similar to the whole-grain wheat-fiber diet recommended for cardiovascular risk reduction, the low-GI diet may also be effective for CVD risk reduction.

Purpose: To investigate the safety and efficacy of micropulse (MP) macular laser in combination with intravitreal aflibercept for the treatment of center-involved diabetic macular edema (CI-DME). Methods: A single-blind prospective randomized controlled pilot trial was performed. In total, 30 eyes of 30 patients with CI-DME and best corrected visual acuity (BCVA) between, and including, 20/30 and 20/400 were enrolled. Enrolled eyes were randomized to 2 groups. Group 1 received intravitreal aflibercept injections (IVT-AFL) with sham laser. Group 2 received IVT-AFL with MP laser. Both groups were followed every 4 weeks for 48 weeks and retreatment was performed on pro re nata basis according to preset criteria. The main outcome measure was the average number of intravitreal injections for each group at 48 weeks. Secondary outcome measures included changes in BCVA and central macular thickness (CMT) at 24 and 48 weeks. Results: The average number of intravitreal injections at 48 weeks was similar between the groups (8.5±3.3 in Group 1 vs 7.9±3.6 in Group 2, p=0.61). After 48 weeks, both groups demonstrated an improvement in BCVA and CMT. However, the difference in improvement between the groups was not statistically significant (p=0.18 for BCVA and p=0.57 for CMT). Conclusion: Intravitreal injections of aflibercept led to improvements in BCVA and CMT at 24 and 48 weeks. Addition of MP laser to eyes in group 2 did not offer additional benefit in reducing treatment burden or improving CMT. Eyes that received MP laser showed a numerically greater improvement in BCVA, although this was not statistically significant. Clinicaltrialsgov Identifier: NCT03143192 March 8, 2017.
RESUMO
PURPOSE: Suboptimal functional outcomes after rhegmatogenous retinal detachment (RRD) repair may be related to photoreceptor abnormalities, including alterations of the ellipsoid zone (EZ) that may not be apparent on cross-sectional optical coherence tomography (OCT). This study assessed EZ recovery using en face OCT after RRD repair and its association with visual acuity. DESIGN: Post hoc analysis of a randomized controlled trial. METHODS: Patients with macula-off RRD were monitored at 3, 6, 12, and 24 months postoperatively and annually thereafter. En face OCT of the EZ slab were analyzed. Hyporeflective areas were colocalized with EZ abnormalities on cross-sectional OCT B-scans and measured by 2 masked graders. Primary outcome was change in area of EZ hyporeflectivity from 3 to 24 months, and its association with Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity recovery was also assessed. RESULTS: In total, 271 images of 61 patients were assessed. Mean area of hyporeflectivity significantly decreased from 3 to 24 months (-2.98 mm2; 95% CI, 1.82-4.13 mm2; P < .0001), with further reductions up to 4 years. Linear regression revealed an association between change in hyporeflective area and change in the ETDRS letter score from 3 to 24 months (ß = -0.31, P = .009, R2 = 14.8%) and between duration of macula-off and change in hyporeflective area from 3 to 24 months (ß = -0.37, P = .018, R2 = 13.7%). CONCLUSIONS: En face OCT provides a novel biomarker for visualizing and quantifying EZ recovery after RRD repair that is associated with ETDRS visual acuity recovery. A steady decline in the area of EZ hyporeflectivity was observed over many years with delayed recovery in patients with longer duration of macula-off.

PURPOSE: To assess the incidence of postoperative outer retinal folds (ORFs) after pars plana vitrectomy (PPV) vs. pneumatic retinopexy (PnR) for rhegmatogenous retinal detachment (RRD) repair and to determine the association of ORFs with functional outcomes at 1 year. DESIGN: Randomized controlled trial. PARTICIPANTS: Patients with primary macula-off RRD meeting the Pneumatic Retinopexy versus Vitrectomy for the Management of Primary Rhegmatogenous Retinal Detachment Outcomes Randomized (PIVOT) trial criteria who were randomly assigned to undergo PPV or PnR. METHODS: Post hoc analysis of the PIVOT trial. The incidence and quantitative morphologic features of ORFs were assessed using en face and cross-sectional OCT at 1 month postoperatively by 2 masked graders. The ETDRS letter score was measured and quantitative assessment of metamorphopsia was performed at 1 year. MAIN OUTCOME MEASURES: Proportion of patients with ORFs at 1 month postoperatively among those who underwent PPV versus PnR. The secondary outcomes included the association of ORFs with visual acuity (ETDRS letter score) and metamorphopsia via metamorphopsia charts at 12 months postoperatively. RESULTS: Of 176 participants enrolled in PIVOT, 88 were macula-off RRDs. Of them, 94.3% (83 of 88) underwent postoperative OCT scans that were gradable at month 1, 93.2% (41 of 44) in the PPV group and 95.5% (42 of 44) in the PnR group. The incidence of ORF formation was 34.1% (14 of 41) in the PPV group and 14.3% (6 of 42) in the PnR group (P = 0.034). The ETDRS letter score at 1 year was 65.7 ± 6.6 letters in patients with ORFs vs. 75.1 ± 1.4 letters in those without ORFs (difference = 9.4 letters, 95% confidence interval [CI] = 7.5-11.3, P = 0.047). Among patients in the PPV group alone, the mean ETDRS letter score at 1 year in patients with ORFs was 62.8 ± 24.7 letters, compared with 75.4 ± 9.2 letters in patients without ORF formation (difference = 12.6 letters, 95% CI = 0.05-24.59, P = 0.04). Horizontal and vertical metamorphopsia scores were similar in patients with and without ORFs: horizontal, 0.35 ± 0.12 vs. 0.29 ± 0.07 (difference = 0.06, 95% CI = 0.01-0.11, P = 0.69); vertical, 0.25 ± 0.07 vs. 0.29 ± 0.07 (difference = 0.04, 95% CI = 0-0.08, P = 0.60). There was a negative correlation between the closest distance of an ORF from the fovea and vertical metamorphopsia score (r = -0.507, P = 0.045). CONCLUSIONS: There is greater risk of developing ORFs after PPV compared to PnR for primary RRD. Outer retinal folds at 1 month are associated with significantly worse ETDRS visual acuity letter scores at 1 year.

IMPORTANCE: Pneumatic retinopexy (PnR) is associated with superior visual acuity and reduced vertical metamorphopsia compared with pars plana vitrectomy (PPV) for primary rhegmatogenous retinal detachment (RRD). It is important to determine postoperative photoreceptor integrity with both surgical techniques. OBJECTIVE: To compare photoreceptor integrity on spectral domain-optical coherence tomography (SD-OCT) between PnR and PPV at 12 months postoperatively. DESIGN, SETTING, AND PARTICIPANTS: Post hoc analysis of the Pneumatic Retinopexy Versus Vitrectomy for the Management of Primary Rhegmatogenous Retinal Detachment Outcomes Randomized Trial (PIVOT) conducted between August 2012 and May 2017 at St Michael's Hospital, Toronto, Ontario, Canada. Primary RRDs with specific criteria were included. Data were analyzed between April and August 2020. INTERVENTION: Randomization to PnR vs PPV stratified by macular status. MAIN OUTCOMES AND MEASURES: Difference in proportion of patients with discontinuity of the ellipsoid zone (EZ) and external limiting membrane (ELM) between groups assessed independently by 2 masked graders at an external masked image reading center. RESULTS: A total of 150 participants completed the 12-month follow-up visit. A total of 145 patients (72 PPV and 73 PnR) had gradable spectral-domain optical coherence tomography at 12 months. Analysis of the central 3-mm (foveal) scans found that 24% (n = 17 of 72) vs 7% (n = 5 of 73) displayed EZ discontinuity (difference, 17%; odds ratio [OR], 4.204; 95% CI, 1.458-12.116; P = .005) and 20% (n = 14 of 71) vs 6% (n = 4 of 73) displayed ELM discontinuity (difference, 14%; OR, 4.237; 95% CI, 1.321-13.587; P = .01) in the PPV and PnR groups, respectively. Analysis of the 6-mm (foveal and nonfoveal) scans revealed that EZ and ELM discontinuity was greater in the PPV vs PnR groups (EZ, 32% [n = 23 of 72] vs 11% [n = 8 of 73]; difference, 21%; OR, 3.814; 95% CI, 1.573-9.249; P = .002; ELM, 32% [n = 23 of 71] vs 18% [n = 13 of 73]; difference, 14%; OR, 2.211; 95% CI, 1.015-4.819; P = .04). CONCLUSIONS AND RELEVANCE: Discontinuity of the EZ and ELM was more common at 12 months postoperatively following PPV vs PnR for RRD repair. The findings of this post hoc analysis suggest that less discontinuity of the EZ and ELM may provide an anatomic basis for the previously reported superior functional outcomes with PnR, although the analysis does not prove a cause-and-effect relationship.

These recommendations, produced by a group of Canadian retina experts, have been developed to assist both retina specialists and general ophthalmologists in the management of vision-threatening neovascular age-related macular degeneration (nAMD). The recommendations are based on published evidence as well as collective experience and expertise in routine clinical practice. We provide an update on practice principles for optimal patient care, focusing on identified imaging biomarkers, in particular retinal fluid, as well as current and emerging therapeutic approaches. Algorithms for delivering high-quality care and improving long-term patient outcomes are provided, with an emphasis on timely and appropriate treatment to preserve and maintain vision. In the context of nAMD, increasing macular fluid or leakage on fluorescein angiography (FA) may indicate disease activity regardless of its location. Early elimination of intraretinal fluid (IRF) is of particular relevance as it is a prognostic indicator of worse visual outcomes. Robust referral pathways for second opinion and peer-to-peer consultations must be in place for cases not responding to intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy.

Importance: Although 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). Objective: To explore the differences in various aspects of VRQoL between pneumatic retinopexy (PnR) and pars plana vitrectomy (PPV) following RRD repair. Design, Setting, and Participants: Post 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 Measures: Differences 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. Results: A 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 Relevance: These 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.

Importance: Retinal displacement following rhegmatogenous retinal detachment repair may have consequences for visual function. It is important to know whether surgical technique is associated with risk of displacement. Objective: To compare retinal displacement following rhegmatogenous retinal detachment repair with pneumatic retinopexy (PR) vs pars plana vitrectomy (PPV). Interventions or Exposures: Fundus autofluorescence images were assessed by graders masked to surgical technique. Design, Setting, and Participants: A multicenter retrospective consecutive case series in Canada and the UK. A total of 238 patients (238 eyes) with rhegmatogenous retinal detachments treated with PR or PPV who underwent fundus autofluorescence imaging from November 11, 2017, to March 22, 2019, were included. Main Outcomes and Measures: Proportion of patients with retinal displacement detected by retinal vessel printings on fundus autofluorescence imaging in PR vs PPV. Results: Of the 238 patients included in the study, 144 were men (60.5%) and 94 were women (39.5%); mean (SD) age was 62.0 (11.0) years. Of the 238 eyes included in this study, 114 underwent PR (47.9%) and 124 underwent PPV (52.1%) as the final procedure to achieve reattachment. Median time from surgical procedure to fundus autofluorescence imaging was 3 months (interquartile range, 1-5 months). Baseline characteristics in both groups were similar. The proportion of eyes with retinal vessel printing on fundus autofluorescence was 7.0% for PR (8 of 114) and 44.4% for PPV (55 of 124) (37.4% difference; 95% CI, 27.4%-47.3%; P < .001). Analysis based on the initial procedure found that 42.4% (42 of 99) of the eyes in the PPV group vs 15.1% (21 of 139) of the eyes in the PR group (including 13 PR failures with subsequent PPV) had displacement (27.3% difference; 95% CI, 15.9%-38.7%; P < .001). Among eyes with displacement in the macula, the mean (SD) displacement was 0.137 (0.086) mm (n = 6) for PR vs 0.297 (0.283) mm (n = 52) for PPV (0.160-mm difference; 95% CI, 0.057-0.263 mm; P = .006). Mean postoperative logMAR visual acuity was 0.31 (0.32) (n = 134) (Snellen equivalent 20/40) in eyes that initially underwent PR and 0.56 (0.42) (n = 84) (Snellen equivalent 20/72) in eyes that had PPV (-0.25 difference; 95% CI, -0.14 to -0.35; P < .001). Among eyes with displacement, mean postoperative logMAR visual acuity was 0.42 (0.42) (n = 20) (Snellen equivalent 20/52) in those that initially underwent PR and 0.66 (0.47) (n = 33) (Snellen equivalent 20/91) in those that initially underwent PPV (-0.24 difference; 95% CI, -0.48 to 0.01; P = .07). Conclusions and Relevance: These findings suggest that retinal displacement occurs more frequently and is more severe with PPV vs PR when considering the initial and final procedure used to achieve retinal reattachment. Recognizing the importance of anatomic integrity by assessing retinal displacement following reattachment may lead to refinements in vitreoretinal surgery techniques.

PURPOSE: To determine the association of aqueous humor cytokine concentrations with long-term treatment response to anti-vascular endothelial growth factor (VEGF) agents in diabetic macular edema (DME). DESIGN: Retrospective case series. METHODS: Pooled data of aqueous humor cytokine concentrations collected at baseline and 2-month follow-up (2 injections) for treatment-naïve eyes with center-involving DME previously enrolled in a prospective study were reviewed. Subjects receiving intravitreal anti-VEGF injections outside of study protocol as per standard of care were classified into Responders versus Nonresponders based on qualitative assessment of optical coherence tomography for persistence of DME at longitudinal follow-up visits. RESULTS: Of the 41 eyes, 85% were classified as Responders with a significant decline in baseline central subfield thickness and macular volume (P values < .001), and 15% were identified as Nonresponders to anti-VEGF therapy over 51.4 ± 18.7 months of follow-up. No significant difference in baseline aqueous humor VEGF concentration was noted, while at the 2-month follow-up the Nonresponder group had a significantly higher VEGF concentration compared with the Responder group (451.5 ± 690.9 pg/mL vs 113.7 ± 211.4 pg/mL; P = .02). The Responder group also demonstrated a significant decline from baseline to 2-month follow-up in concentration of intercellular adhesion molecule-1 (P < .001), interleukin-10 (P = .041), monocyte chemotactic protein-1 (P = .046), placental growth factor (P = .027), and transforming growth factor-ß2 (P = .017). CONCLUSIONS: Aqueous humor cytokine concentrations serve as an early biomarker for long-term response to anti-VEGF therapy and may enable more effective treatment regimens that improve anatomical outcomes in eyes with DME.

OBJECTIVE: To evaluate the outcomes and complications of bilateral same-day intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections. METHODS: This is a single-center, retrospective study that included 524 eyes of 262 patients who received concomitant bilateral intravitreal anti-VEGF injections in 2016 at St. Michael's Hospital, Toronto. If any of the patients were receiving simultaneous bilateral injections on a regular basis prior to 2016, data pertaining to previous injections were also reviewed. Everyone received bevacizumab, ranibizumab, or aflibercept in an office setting. RESULTS: A total of 9,798 intravitreal anti-VEGF injections (4,899 bilateral injection sessions) were performed in 524 eyes of 262 patients. The average number of bilateral injection sessions per patient was 18.7 ± 14.1. Ranibizumab was the most commonly used anti-VEGF drug (83.8%). The incidence of endophthalmitis was 0.01%, and there were 2 episodes of acute intraocular inflammation among the 9,798 injections (0.02%). All 3 cases occurred after treatment with ranibizumab. There were 2 deaths (0.76%) due to nonvascular causes but no vascular related systemic adverse events were reported. CONCLUSIONS: Same-day bilateral intravitreal anti-VEGF injections present a low rate of complications and are well tolerated by patients. This safe practice may reduce the burden on the health-care system and on the patients.

INTRODUCTION: Amyotrophic lateral sclerosis (ALS) patients benefit from multidisciplinary care in an ALS clinic. We studied whether multidisciplinary care of ALS patients using the store and forward method of telemedicine was feasible and acceptable to patients and providers. METHODS: ALS patients seen in the University of Florida (UF) Jacksonville ALS clinic were eligible for our study. A trained telemedicine nurse performed and recorded a multidisciplinary assessment of the patient in their home. Clinic team members reviewed the assessments and provided recommendations, and the clinic director discussed the plan with the patient via videoconference. Patient and provider satisfaction was evaluated using surveys. RESULTS: Eighteen patients completed a total of 27 telemedicine visits. Patient satisfaction was excellent and provider satisfaction was very good. DISCUSSION: The store and forward method of telemedicine is an acceptable alternative to live telemedicine for the multidisciplinary care of ALS patients. This method of care may improve access to multidisciplinary care for this patient population. Muscle Nerve 59:34-39, 2019.

PURPOSE: The optimal surgery to repair rhegmatogenous retinal detachment (RRD) is unknown. The purpose of this trial was to compare outcomes of pneumatic retinopexy (PnR) versus pars plana vitrectomy (PPV) for the management of primary RRD. DESIGN: Prospective, randomized controlled trial. PARTICIPANTS: Patients with RRD demonstrating a single retinal break or a group of breaks in detached retina within 1 clock hour above the 8- and 4-o'clock meridians, with any number, location and size of retinal breaks or lattice degeneration in attached retina. METHODS: Patients were randomized to undergo either PnR or PPV. Macula-on and macula-off patients were assigned to intervention group by stratified randomization and were treated within 24 and 72 hours, respectively. MAIN OUTCOME MEASURES: The primary outcome was 1-year Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity (VA). Important secondary outcomes were subjective visual function (25-item National Eye Institute Visual Function Questionnaire), metamorphopsia score (M-CHARTS), and primary anatomic success. RESULTS: One hundred seventy-six patients were recruited between August 2012 and May 2016. ETDRS VA after PnR exceeded that after PPV by 4.9 letters at 12 months (79.9±10.4 letters vs. 75.0±15.2 letters; P = 0.024). Mean ETDRS VA also was superior for the PnR group compared with the PPV group at 3 months (78.4±12.3 letters vs. 68.5±17.8 letters) and 6 months (79.2±11.1 letters vs. 68.6±17.2 letters). Composite 25-item National Eye Institute Visual Function Questionnaire scores were superior for PnR at 3 and 6 months. Vertical metamorphopsia scores were superior for the PnR group compared with the PPV group at 12 months (0.14±0.29 vs. 0.28±0.42; P = 0.026). Primary anatomic success at 12 months was achieved by 80.8% of patients undergoing PnR versus 93.2% undergoing PPV (P = 0.045), with 98.7% and 98.6%, respectively, achieving secondary anatomic success. Sixty-five percent of phakic patients in the PPV arm underwent cataract surgery in the study eye before 12 months versus 16% in the PnR group (P < 0.001). CONCLUSIONS: Pneumatic retinopexy should be considered the first line treatment for RRD in patients fulfilling Pneumatic Retinopexy versus Vitrectomy for the Management of Primary Rhegmatogenous Retinal Detachment Outcomes Randomized Trial (PIVOT) recruitment criteria. Pneumatic retinopexy offers superior VA, less vertical metamorphopsia, and reduced morbidity when compared with PPV.

OBJECTIVE: To compare the anatomical and visual outcomes of patients with bilateral macular holes (MH) who have been treated with pars plana vitrectomy in one eye and intravitreal ocriplasmin in the fellow eye. DESIGN: Multicentre, retrospective case series. PARTICIPANTS: Twenty-two eyes of 11 patients with bilateral MH treated with vitrectomy in one eye and ocriplasmin in the other were included. Patients were followed-up by 5 vitreoretinal surgeons from 3 retinal practices in Canada. METHODS: All charts were reviewed for data collection, and optical coherence tomography (OCT) scans pre- and posttreatment were evaluated. RESULTS: MH closed primarily in 36.4% (n = 4) of the ocriplasmin-treated eyes and in 90.9% (n = 10) of the vitrectomy-treated eyes (p = 0.031). The 4 successfully treated ocriplasmin MH were preceded by a vitreomacular traction (VMT) release. Three additional ocriplasmin-treated eyes achieved a VMT release without MH closure. All persistent MH (100%) closed with subsequent vitrectomy, with no significant difference in final best-corrected visual acuity (BCVA) between those who achieved MH closure with primary or secondary interventions (p = 0.073). Final BCVA improved from logMAR 0.85 ± 0.34 to 0.37 ± 0.22 (p = 0.005) in the vitrectomy eyes and from 0.56 ± 0.28 to 0.28 ± 0.16 (p = 0.009) in the ocriplasmin eyes, with no significant difference in final BCVA between treatments (p = 0.306). Postoperative ellipsoid zone disruption persisted more frequently in vitrectomy-treated eyes. CONCLUSION: Both procedures were associated with improved visual outcomes, but eyes initially treated with vitrectomy had a higher primary MH closure rate. On OCT, patients had more outer structural changes in vitrectomy eyes than in ocriplasmin eyes.
