RESUMEN
PURPOSE: To study the treatment patterns, visual outcomes and safety profile of intravitreal dexamethasone implant (IDI) used for the treatment of macular edema secondary to retinal vein occlusion. METHODS: Up to 2 years of routinely collected anonymized data within electronic medical record systems were remotely extracted from 16 centers. The outcome measures include visual outcome, number of injections, and safety measures, including the rate of intraocular pressure (IOP) rise, frequency of IOP-lowering medication usage, and cataract surgery rates. RESULTS: The study included 688 eyes (44.4%) with central retinal vein occlusion and 862 eyes (55.6%) with branch retinal vein occlusion; 1,250 eyes (80.6%) were treatment naive and 28% (275/989) had high IOP or were on IOP-lowering medications before IDI use. It was found that 31% (476) of eyes received two injections, and 11.7% (182) and 3.7% (58) of eyes received three and four injections, respectively. The mean baseline Snellen visual acuity improved from 20/125 to 20/40 after the first injection. The probability of cataract surgery was 15% at 24 months. The proportion of eyes with ≥10 mmHg change from baseline was higher in phakic (14.2%) compared with pseudophakic eyes (5.4%, P = 0.004). Three eyes required IOP filtering surgery (0.2%). CONCLUSION: The visual results of IDI in eyes with macular edema secondary to retinal vein occlusion in the real world are comparable to those of clinical trial setting. Increased IOP in eyes with preexisting ocular hypertension or glaucoma can be controlled with additional medical treatment. Intraocular pressure rise with IDI may be more frequent in phakic than in pseudophakic eyes.

PURPOSE: A vignette study to examine treatment decisions made by UK hospital optometrists in patients with neovascular age-related macular degeneration (nAMD) and the effect of optometrists' experience on agreement. METHODS: Patients with nAMD attending Manchester Royal Eye Hospital, Manchester, UK were identified as potential candidates for the case series of vignettes. The cases were chosen to reflect a varied case-mix with respect to difficulty as well as ensuring good quality of the images. Each vignette included a history summary consisting of the number of previous injections given and visual acuity measurements at baseline, the previous visit, and the current visit. Images were compiled to show baseline fundus photographs and ocular coherence tomography (OCT) images with the current visit images on which the treatment decision was to be made along with the images from the previous visit. Hospital optometrists were recruited and asked to complete the series of vignettes, deciding if treatment was required at that visit and how confident they felt with that decision. Their responses were compared to the reference standard created by a consensus of consultant ophthalmologists with a sub-speciality interest in medical retina. RESULTS: Regarding treatment decision for optometrists, the percentage correct value was 75% with the sensitivity being 75.6% (95% CI 70.1-80.3) and the specificity as 75.1% (95% CI 72.1-77.8). No statistically significant difference was found between differing levels of experience. However, there was a significant difference in confidence levels between groups. Potentially sight threatening decisions accounted for 6.4% of the optometrists' decisions, 3.5% were made with a high confidence rating suggesting no discussion with an ophthalmologist was required. CONCLUSIONS: Although the optometrists showed modest agreement with the reference standard in a series of cases that have higher than average complexity, the optometrists showed a similar amount of variability within their treatment decisions compared to the reference standard. The optometrists were therefore not inferior in their performance compared to the ophthalmologists and this can be seen as supporting evidence for their extended role within this clinical area. Experience did not have an effect on 'correct' treatment decisions although there was a statistically significant effect on increasing confidence of treatment decision.

PURPOSE: To understand levels of disease burden and progression in a real-world setting among patients from the United Kingdom with bilateral geographic atrophy (GA) secondary to age-related macular degeneration (AMD). DESIGN: Retrospective cohort analysis of a multicenter electronic medical record (EMR) database. PARTICIPANTS: Patients who were aged ≥50 years with bilateral GA and no history of choroidal neovascularization (CNV) and who attended 1 of 10 clinical sites using the EMR. METHODS: A deidentified data set was constructed from the records held at the 10 sites. An algorithm was used to extract cases with a GA diagnosis, of which 1901 had bilateral GA and form the basis of this report. A sample of records randomly selected from each center was used to validate disease definitions. MAIN OUTCOME MEASURES: Progression to blindness (visual acuity [VA] <20 letters or Snellen 3/60 in the better-seeing eye), driving ineligibility (VA ≤70 letters or Snellen 6/12 in the better-seeing eye), progression to CNV, loss of 10 or more letters, and mean change in VA over time. RESULTS: At first record of GA, 7.1% had a VA in the better-seeing eye equal to or lower than the cutoff for blindness registration and 71.1% had a VA that would have rendered them ineligible to drive. Over time, 16% became legally blind (median time to outcome, 6.2 years) and 66.7% became ineligible to drive (median time to outcome, 1.6 years). In the worse-seeing eye, 40.1% lost ≥10 letters in 2.4 years. Among patients with baseline and 24-month VA measurements, mean VA decline was 6.1 letters in the worse-seeing eye (n = 413) and 12.4 letters in the better-seeing eye (n = 414). The rate of progression to CNV in either eye was 7.4% per patient-year. CONCLUSIONS: At initial diagnosis, based on VA in the better-seeing eye, a high proportion of patients with bilateral GA were ineligible to drive and approximately 7% were eligible for UK blindness registration. The subsequent reduction in VA that occurred in the better-seeing eye would render a further two-thirds ineligible to drive. These findings emphasize the severity of the visual disability associated with GA secondary to AMD.

PURPOSE: Aflibercept has the potential advantage of reducing capacity problems by allowing 2 monthly visits for patients with neovascular macular degeneration (nAMD) compared with monthly pro re nata regimens that are the most commonly used in the United Kingdom. This study aimed to report the visual outcomes achieved in routine clinical practice using the VEGF Trap-Eye: Investigation of Efficacy and Safety in Wet AMD (VIEW) protocol at 1 year and compare with trials data and other real-world reports. DESIGN: Retrospective data analysis from an electronic medical record. PARTICIPANTS: Consecutive series of treatment-naïve patients initiated on aflibercept for nAMD at least 1 year before data extraction. METHODS: Data were anonymized and remotely extracted from 16 centers in the United Kingdom that use the same electronic medical record (EMR) system (Medisoft Ophthalmology; Medisoft Limited, Leeds, UK). MAIN OUTCOME MEASURES: The minimum data set defined before first data entry and mandated by the EMR included age, gender, visual acuity, injection episodes, and complications. RESULTS: The mean age was 80.0 years (median, 81.0 years) and 63.7% were women. During the first year of treatment with aflibercept, 1840 treatment-naïve eyes of 1682 patients received a median of 8 (mean, 7.0) injections at a median of 8 (mean, 7.3) visits. The mean baseline visual acuity was 53.7 letters, improving to 58.8 letters (+5.1-letter gain) at 1 year. In first-treated eyes, the respective figures were 52.7 letters at baseline and 58.2 letters at 1 year, a gain of +5.5 letters. The proportion achieving 70 letters or more increased from 16.4% at baseline to 33.7% at 1 year, and 92% avoided moderate visual loss at 1 year. CONCLUSIONS: The visual acuity outcomes are comparable to randomized trials and better than many previous real-world data collections, with a mean +5.1-letter gain at 1 year compared with +8.4 letters in the integrated analysis of the VIEW 1 and VIEW 2 studies. Early visual gains were maintained through the year. Collection of outcomes beyond clinical trials can have limitations but better reflect the full pool of patients actually treated and are important to determine whether a particular treatment is performing as expected. Such data also have the potential to improve services by setting up a mechanism to compare sites.

PURPOSE: To evaluate the efficacy and safety of intravitreal bevacizumab (Avastin; Genentech, South San Francisco, CA) in patients with neovascular age-related macular degeneration (nAMD) using 2 different treatment regimens in which patients were assessed clinically at up to 12-week intervals. DESIGN: Randomized, controlled, noninferiority trial. PARTICIPANTS: A total of 331 patients with nAMD. METHODS: Patients were treated with 1.25 mg intravitreal bevacizumab and followed up to 92 weeks. They were randomized into 2 arms. All patients received 3 loading doses 4 weeks apart and thereafter were assessed every 12 weeks until the end of the study. One arm received a routine treatment at each 12-week assessment, and the other arm was treated at these assessments on an as-needed basis. After the loading doses, patients in either arm who showed signs of disease activity had an additional assessment after 6 weeks and at that visit had top-up treatments on an as-needed basis. MAIN OUTCOME MEASURES: Mean best-corrected visual acuity (BCVA) at 92 weeks. RESULTS: At 92 weeks, patients who had treatments every 12 weeks had superior BCVA to those treated on an as-needed basis every 12 weeks (P = 0.008), with the regular treatment arm gaining a mean BCVA of 5.5 letters and the as-needed treatment arm gaining 0.6 letters. The regular treatment arm of the study showed significantly improved outcomes with respect to 5-, 10-, and 15-letter changes in BCVA from baseline compared with the as-needed treatment arm, as well as superior reading speed. In patients who completed the study, up to but not including week 92, the mean number of treatments was 10.8 for the regular treatment arm and 9.1 for the as-needed treatment arm. CONCLUSIONS: A treatment regimen with regular bevacizumab injections every 12 weeks after loading doses supplemented with as-needed top-up treatments produced a stable improvement in BCVA from baseline. The improvement in BCVA was broadly similar to that obtained in other studies using anti-vascular endothelial growth factor drugs with more frequent assessments and treatments.

PURPOSE: To assess repeatability of visual function measures in patients with early, intermediate or late age-related macular degeneration (AMD) without active neovascular disease in the study eye, but active neovascular AMD in the fellow eye. METHODS: One hundred subjects from an ongoing trial were screened for this study in which their LogMAR acuity, contrast sensitivity and reading performance were assessed using standardised protocols by trained optometrists. The same measures were repeated one month later and repeatability of the visual functions assessed. RESULTS: Data from 83 subjects satisfied inclusion criteria for analysis. Coefficient of repeatability was 14.9 letters for LogMAR visual acuity , 7.2 letters for Pelli Robson contrast sensitivity, 0.72 for LogMAR reading acuity, 110.4 words/ min for reading speed and 0.67 for LogMAR critical print size. Intraclass correlation coefficients allowed comparison between measures and were found to be 0.96 for LogMAR visual acuity, 0.93 for contrast sensitivity, 0.75 for LogMAR reading acuity, 0.79 for reading speed and 0.74 for LogMAR critical print size. Coefficients of variation were 9.4 %, 10.7 %, 48.4 %, 28.4 % and 31.8 % respectively. CONCLUSIONS: We found coefficients of repeatability that concurred with previous studies demonstrating variability of visual functions in patients with AMD. In addition, we found intraclass correlation coefficients to be better with visual acuity and contrast sensitivity than with measures of reading performance.

PURPOSE: Data are limited pertaining to the long-term benefits of aflibercept treatment for neovascular age-related macular degeneration (nAMD). The aim of this study was to provide outcomes, safety, durability and quality-of-life data with aflibercept using a modified treat, extend and fixed regime over 4 years. METHODS: Prospective, multicentre, single cohort observational study of treatment-naïve nAMD participants treated with aflibercept as 2-year extension of the MATE-trial that compared early and late Treat-and-Extend for 2 years. Refracted ETDRS best corrected visual acuity (BCVA), central retinal thickness (CRT), treatment interval and adverse events were assessed. Quality-of-life was measured using the Macular Disease Dependent Quality of Life (MacDQoL) and Macular Disease Treatment Satisfaction Questionnaires (MacTSQ). RESULTS: Twenty-six of 40 participants completing the MATE-trial were enrolled with 20 completing the total 4-year study. Mean BCVA was 60.7 at Month 0 and 64.8 ETDRS letters at Month 48 while CRT decreased from 423.7 µm to 292.2 µm. Five participants discontinued treatment due to inactivity. The mean number of treatments and visits for the remaining participants was 27 and 30.0, respectively, with treatment intervals extended to 12 weeks in four participants at Month 48. Both AMD-specific QoL and treatment satisfaction remained stable between Months 0 and 48 and mean BCVA significantly correlated with AMD-specific QoL scores at Months 12, 24 and 48. CONCLUSIONS: Results suggest that BCVA can be maintained over 48 months when following a treat-extend-and-fix regimen of aflibercept with intervals out to 12 weeks, while maintaining AMD-specific QoL and treatment satisfaction.

OBJECTIVE: Current cost-effectiveness analyses (CEA) emphasize drug costs as the differentiator between NICE recommended anti-VEGF treatments but may neglect real-world non-drug costs of running nAMD services in the UK. To address this, this study identified real-world non-drug service cost items relevant to UK NHS nAMD clinics, including costs arising from operational strain (demand exceeding capacity). METHODS: Cost items were identified by a structured literature review of peer-reviewed and grey literature, and an expert panel of 10 UK-based ophthalmologists with relevance to real-world practice. These items underwent meta-synthesis and were then determined in a consensus exercise. RESULTS: Of 237 cost items identified, 217 (91.6%) met the consensus threshold of >0.51 and were included in the nAMD Service Non-Drug Cost Instrument (nAS). Sensitivity of cost items taken from UK Health Technology Assessment (HTA) using the nAS as the reference standard was low (HTAmin: 1.84%, 95% CI 0.50-4.65%; HTAmax: 70.51%, 95% CI 63.96-76.49%). False negative rates showed variable likelihood of misclassifying a service by cost burden depending on prevalence. Scenario analysis using cost magnitudes estimated annual per-patient clinic cost at £845 (within capacity) to £13,960 (under strain) compared to an HTAmin estimate of £210. Accounting for cost of strain under an assumed 50% increase in health resource utilization influenced cost-effectiveness in a hypothetical genericisation scenario. CONCLUSION: Findings suggested that HTA underestimates UK NHS nAMD clinic cost burden with cost of strain contributing substantial additional unmeasured expense with impact on CEA. Given potential undertreatment due to strain, durability is suggested as one of the relevant factors in CEA of nAMD anti-VEGF treatments due to robustness under limited capacity conditions affecting UK ophthalmology services.
When considering how well treatments work versus how much they cost, the focus is usually only on the price of the medicine itself. However, other real-world costs exist. In the UK, when treating certain eye problems such as neovascular age-related macular degeneration (nAMD), there are additional expenses related to running clinics and managing treatments that often go unnoticed. To get a better understanding of these hidden costs, the study examined factors like clinic workload and the extra expenses that come with it. Ten eye doctors in the UK were consulted for their expert opinions and numerous research papers were reviewed to identify these additional costs. The study grouped different costs in a tool called the nAMD Service Non-Drug Cost Instrument (nAS). When the findings of the nAS tool were compared to the usual methods of calculating costs, it was found that the conventional approach overlooked many of the actual expenses. Busy clinics face unique challenges, such as higher operational costs associated with staffing for extended hours, emergency appointments, extended waiting times and the potential to miss optimal treatment windows. This can lead to disease progression and the onset of comorbidities, which require more complex and costly treatments. Recognizing these real costs is crucial when making decisions about treatments, especially when treatments require more frequent visits to eye clinics. This study emphasizes the importance of considering all expenses, not just the obvious ones like medication and doctor visits when determining the most effective way to manage eye conditions like nAMD in the UK.

OBJECTIVES: This report, based on guidance from a panel of UK retina specialists, introduces a revised intravitreal aflibercept (IVT-AFL) treat-and-extend (T&E) pathway for the treatment of neovascular age-related macular degeneration (nAMD). The T&E pathway incorporates the updated IVT-AFL label (April 2021) allowing flexible treatment intervals of 4 weeks to 16 weeks, after three initiation doses and a further dose after 8 weeks. Practical guidance is provided on the clinical implementation of the revised pathway, with the aim of supporting clinical decision-making to benefit patients and addressing capacity issues in nAMD services. METHODS: Three structured round-table meetings of UK retina specialists were held online on 19 May, 16 June and 13 October 2021. These meetings were organised and funded by Bayer. RESULTS: The authors revised the previously published consensus pathway to reflect the changes to the IVT-AFL label and developed guidelines for the implementation of the pathway in UK clinical practice. The guidelines include topics such as recommendations for extending patients with 2- or 4-week adjustments, extending patients to 16-week treatment intervals, managing fellow eye involvement, and reducing treatment intervals for patients with particularly active disease. CONCLUSIONS: The revised IVT-AFL T&E nAMD pathway offers guidance to clinicians seeking to increase the dosing flexibility of IVT-AFL, with 4- to 16-week treatment intervals, in line with the updated IVT-AFL label, to meet the continually evolving demands of nAMD service provision.

BACKGROUND/OBJECTIVES: In healthcare research investigating complex interventions, gaps in understanding of processes can be filled by using qualitative methods alongside a quantitative approach. The aim of this mixed-methods pilot trial was to provide feasibility evidence comparing two treatment regimens for neovascular age-related macular degeneration (nAMD) to inform a future large-scale randomised controlled trial (RCT). SUBJECTS/METHODS: Forty-four treatment-naïve nAMD patients were followed over 24 months and randomised to one of two treatment regimens: standard care (SC) or treat and extend (T&E). The primary objective evaluated feasibility of the MATE trial via evaluations of screening logs for recruitment rates, nonparticipation and screen fails, whilst qualitative in-depth interviews with key study staff evaluated the recruitment phase and running of the trial. The secondary objective assessed changes in visual acuity and central retinal thickness (CRT) between the two treatment arms. RESULTS: The overall recruitment rate was 3.07 participants per month with a 40.8% non-participation rate, 18.51% screen-failure rate and 15% withdrawal/non-completion rate. Key themes in the recruitment phase included human factors, protocol-related issues, recruitment processes and challenges. Both treatment regimens showed a trend towards a visual acuity gain at month 12 which was not maintained at month 24, whilst CRT reduced similarly in both regimens over the same time period. These were achieved with one less treatment following a T&E regimen. CONCLUSION: This mixed-methodology, pilot RCT achieved its pre-defined recruitment, nonparticipation and screen failure rates, thus deeming it a success. With some minor protocol amendments, progression to a large-scale RCT will be achievable.
RESUMEN
Untreated neovascular age-related macular degeneration (nAMD) can lead to severe and permanent visual impairment. The chronic nature of the disease can have a significant impact on patients' quality of life and an economic and time burden on medical retina (MR) services, with the care need outweighing the growth of resources that clinical services can access. The introduction of a new treatment into clinical services can be challenging, especially for services that are already under capacity constraints. Guidance for practical implementation is therefore helpful. Roundtable meetings, facilitated by Novartis UK, between a working group of MR experts with experience of leading and managing NHS retinal services in the intravitreal era were conducted between 2020 and 2021. These meetings explored various aspects and challenges of introducing a new anti-vascular endothelial growth factor (VEGF) therapy to the UK medical retina services. Provision of clear expert recommendations and practical guidance nationally, that can be adapted locally as required to support clinicians and healthcare professionals (HCPs), is valuable in supporting the introduction of a new anti-VEGF therapy within the NHS environment. The experts provide ophthalmologic HCPs with a collation of insights and recommendations to support the introduction and delivery of brolucizumab in their local service in the face of current and projected growth in demand for retina care.

PURPOSE: To report findings of maculopathy after treatment with sertraline in three patients. METHODS: This case series includes three patients who presented with reduced visual acuity after treatment with sertraline for various psychiatric indications. All patients had been treated with sertraline for varying periods of time between 4 weeks and 5 years. RESULTS: Data were collected from three patients (age range, 27-68 years). All three patients were white females, with both eyes being affected in all cases. The range of presenting visual acuities was between 20/30 and 20/100 after presentation with central visual disturbance. All patients underwent comprehensive ocular examination and imaging with the main ocular findings being outer retinal layer and retinal pigment epithelial disruption. The follow-up period was between 1 and 9 months with final visual acuities between 20/25 and 20/100. Patients showed objective clinical evidence of phenotypically similar maculopathy supported by appropriate imaging CONCLUSION: In this cohort, we report the possible association of sertraline use and associated maculopathy in three patients. This is potentially significant, given the large numbers of patients treated with sertraline currently; however, further evidence is required to both quantify how common this association is and establish a possible causative mechanism.
RESUMEN
INTRODUCTION: The aim of this study was to develop a statistical model to determine the visual significance of subretinal fluid (SRF) in combination with other constructed optical coherence tomography (OCT) features in patients with wet age-related macular degeneration. METHODS: The project used labelled data from 1211 OCTs of patients with neovascular macular degeneration (nAMD) attending the macular treatment centre of Manchester Royal Eye Hospital to build a statistical model to determine vision for any virtual, constructed OCT. A four-dimensional plot was created to represent the visual impact of SRF in OCTs in the context of the associated OCT characteristics of atrophy and subretinal hyperreflective material (SHRM). RESULTS: The plot illustrates that at levels of SRF below 150 µm, the impact of SRF on vision is very low. Increasing the amount of fluid to 200 µm and beyond increases the impact on vision, but only if there is little atrophy or SHRM. CONCLUSIONS: This study suggests that levels of SRF up to around 150 µm thickness on OCT have minimal impact on vision. Greater levels of SRF have greater impact on vision, unless associated with significant amounts of atrophy or SHRM, when the additional effect of the SRF on vision remains low.
RESUMEN
BACKGROUND: Neovascular age-related macular degeneration (nAMD) presents a significant treatment burden for patients, carers and medical retina services. However, significant debate remains regarding how best to manage nAMD when assessing disease activity by optical coherence tomography (OCT), and particularly the significance of different types of fluid and how the understanding of anatomical efficacy can influence treatment strategies. This article provides opinion on the practical implications of anatomical efficacy and significance of fluid in the management of nAMD and proposes recommendations for healthcare professionals (HCPs) to improve understanding and promote best practice to achieve disease control. METHODS: An evidence-based review was performed and an expert panel debate from the Retina Outcomes Group (ROG), a forum of retinal specialists, provided insights and recommendations on the definition, role and practical implications of anatomical efficacy and the significance of fluid at the macula in the management of nAMD. RESULTS: The ROG has developed recommendations for achieving disease control through a zero-tolerance approach to the presence of fluid in nAMD as patients who avoid fluctuations in fluid at the macula have better visual outcomes. Recommendations cover five key areas: service protocol, training, regimen, multidisciplinary teams and engagement. This approach facilitates more standardised protocol-based treatment strategies. CONCLUSIONS: Targeting a fluid-free macula and aiming for disease control are essential to improve outcomes. As new therapies and technologies become available, drying the macula and maintaining disease control will become even more achievable. The outlined recommendations aim to promote best practice among HCPs and medical retina services to improve patient outcomes.
RESUMEN
INTRODUCTION: To explore the potential link between macular atrophy (MA) of the retinal pigment epithelium (RPE) in patients with neovascular age-related macular degeneration (nAMD) and anti-vascular endothelial growth factor (anti-VEGF) treatment. METHODS: Through a balanced overview of the field from a largely clinical perspective, we looked at available evidence on the topic of MA correlation with anti-VEGF therapy and examined possible risk factors for MA development in the context of nAMD treatment with anti-VEGF. RESULTS: Links have been reported to connect both MA incidence and progression to treatment frequency and to the anti-VEGF drug type. CONCLUSIONS: All reports agree on the fact that de novo development of MA in anti-VEGF-treated eyes is frequent and multifactorial. Research data shows an expansion of atrophy during anti-VEGF treatment. There are mixed conclusions about the correlation of MA incidence or progression with treatment-related risk factors. It mostly appears that there is no straightforward link. More clinical research is still needed to further understand this association.
RESUMEN
OBJECTIVES: This report aims to provide clear recommendations and practical guidance from a panel of UK retinal experts on an aflibercept treat-and-extend (T&E) pathway that can be implemented in clinical practice. These recommendations may help service providers across the NHS intending to implement a T&E approach, with the aim of effectively addressing the capacity and resource issues putting strain on UK neovascular age-related macular degeneration (nAMD) services while promoting patients' best interests throughout. METHODS: Two structured roundtable meetings of retinal specialists were held in London, UK on 7 December 2018 and 1 March 2019. These meetings were organised and funded by Bayer. RESULTS: The panel provided recommendations for an aflibercept T&E pathway and developed specific criteria based on visual acuity, retinal morphology and optical coherence tomography imaging to guide reduction, maintenance and extension of injection intervals. They also discussed the extension of treatment intervals by 2- or 4-week adjustments to a maximum treatment interval of 16 weeks, the management of retinal fluid and the stopping of treatment. CONCLUSIONS: The long-term benefits of implementing a T&E pathway may include superior visual outcomes compared with a pro re nata (PRN; as needed) protocol, and a lower treatment burden compared with a fixed protocol, which is likely to improve service capacity. Furthermore, the predictable nature of a T&E approach compared with a PRN service may aid capacity planning for the future nAMD treatment demand.

An aging population leads to increasing demand for medical retina services with chronic diseases being managed in long-term care pathways. Many hospital services struggle to deliver efficient and effective MR care due, at least in part, to infrastructure that does not expand responsively enough to meet the increased demand. A steering committee of retinal specialists from a variety of UK NHS hospital ophthalmology departments with experience of leading and managing NHS retinal services in the intravitreal era came together for the generation of this document to review and compile key aspects that should be considered when optimising intravitreal treatment capacity within MR services. This article aims to provide a useful collation and signposting of key published evidence, consensus and insights on aspects of delivering an intravitreal service, including treatment regimens, virtual clinics, staff training and governance, telemedicine and information technology, and data collection and key performance indicators. The objective is to equip ophthalmologic healthcare professionals with the necessary tools to develop and adapt their local service in the face of current and projected increased demand.
RESUMEN
PURPOSE: To assess the one-year effectiveness and safety of ranibizumab 0.5 mg in treatment- naïve patients with diabetic macular edema (DME) enrolled in the real-world LUMINOUS study. PATIENTS AND METHODS: A 5-year, prospective, observational, open-label, global study which recruited 30,138 patients across all approved indications. Consenting patients (≥18 years) who were treatment-naïve or previously treated with ranibizumab or other ocular treatments were treated as per the local ranibizumab label. Here, we present the change in visual acuity (VA) (Early Treatment Diabetic Retinopathy Study letter score; primary treated eye) at Year 1, as well as the change in VA based on injection frequencies (≤4 and ≥5), treatment exposure, and the overall adverse events (AEs) and serious AEs (SAEs) in treatment-naïve DME patients. RESULTS: Of the 4,710 DME patients enrolled in the study, 1,063 were treatment-naïve. At baseline, mean age was 64.5 years, 54.7% were male, and 69.2% were white. At 1 year, mean VA letter score improved by +3.5 (n = 502) from a baseline of 57.7 with a mean of 4.5 injections. Presented by injection frequencies ≤4 and ≥5, VA letter score gains were 0.5 (n = 264) and 6.9 (n = 238) from baseline letter scores of 56.6 and 59.0, respectively. Over 5 years, the incidence of ocular/non-ocular AEs and SAEs was 7.2%/10.1% and 0.3%/5.8%, respectively. No endophthalmitis cases were reported. CONCLUSIONS: The LUMINOUS study included patients with DME with more diverse baseline characteristics than those in randomized clinical trials. The 1-year data showed improvement in VA with low number of injections in treatment- naïve patients with DME. Greater VA gains were observed in patients who received ≥5 injections. No new safety findings were identified. LUMINOUS confirms the effectiveness and safety of ranibizumab for the treatment of patients with DME in a real-world clinical practice.

PURPOSE: To estimate rates and risk factors for progression to geographic atrophy (GA) or choroidal neovascularization (CNV) among eyes diagnosed with early or intermediate age-related macular degeneration (AMD) in clinical practice. DESIGN: Retrospective cohort analysis of a multicenter electronic medical record (EMR) database from the United Kingdom. PARTICIPANTS: Patients aged 50 years or more with diagnosis of early/intermediate AMD in at least 1 eye (the study eye) and no evidence of CNV or GA in the study eye, from 10 clinical sites using the EMR. METHODS: Anonymized data for 40 543 patients with a diagnosis of early/intermediate AMD were extracted between October 2000 and February 2016 from EMR database records held in the 10 sites. A sample of records randomly selected from each center was used to validate disease definitions. Records were analyzed by subgroup, based on the AMD status of the fellow eye. Multivariate Cox regression models identified other predictors of disease progression. MAIN OUTCOME MEASURES: Progression rate (per 100 person-years) to GA or CNV in study eyes with early/intermediate AMD by fellow eye status and identified risk factors for progression. RESULTS: Study eyes with early/intermediate AMD and a diagnosis of CNV in the fellow eye progressed to CNV fastest (at a rate of 15.2 per 100 person-years), and those with a diagnosis of GA in the fellow eye progressed to GA fastest (11.2 per 100 person-years), compared with the rates per 100 person-years of progression to CNV (3.2-11.9) or GA (2.0-7.8) in the other subgroups. In individuals with bilateral early/intermediate AMD, rates of progression to GA or CNV were 2.0 and 3.2 per 100 person-years, respectively. In the multivariate model, age, female sex, and cardiovascular disease were associated with an increased risk for progression to advanced AMD, whereas diabetes and glaucoma were associated with a decreased rate of progression (hazard ratios, 0.45 and 0.64, respectively). CONCLUSIONS: Progression to GA or CNV was observed frequently in eyes with early/intermediate AMD, with the status of the fellow eye affecting the rate of progression. Novel associations with risk factors were observed and require replication in other cohorts.

INTRODUCTION: The purpose of this review was to explore the potential link between macular atrophy (MA) of the retinal pigment epithelium in patients with neovascular age-related macular degeneration (nAMD) with the disease characteristics and morphological features. METHODS: To this end, we performed a search of peer-reviewed articles published on the PubMed database and included all relevant papers. We then examined these papers for possible risk factors for MA development in the context of nAMD treated with anti-vascular endothelial growth factor drugs, as well as possible protective factors. RESULTS: Our review of the relevant publications revealed that areas of MA can be directly visualized through multiple imaging modalities. Associations have been identified between MA of the retinal pigment epithelium and choroidal neovascular membrane characteristics, intra- and subretinal fluid, pigment epithelial detachment, choroidal thickness, subretinal hyperreflective material, outer retinal tubulations, hemorrhage, subretinal drusenoid deposits, refractile drusen, hyperreflective foci, retinal angiomatous proliferation, polypoidal choroidal vasculopathy, geographic atrophy in the fellow eye, genetic factors, and age. CONCLUSION: The findings of this review indicate that a multimodal approach is recommended for the assessment of MA. The conclusions drawn to date on the correlation between MA development or progression of MA and specific risk factors and possible protective factors are mixed. More clinical research is needed to reach a better understanding of this association.
