The treatment of neovascular (wet) age-related macular degeneration (AMD) with ranibizumab is now very well established in terms of efficacy and safety. Recent clinical trials and real-world studies have demonstrated the advantages of a Treat-and-Extend (T&E) regimen, and many hospital departments are now in the process of adopting this new regimen in favor of the pro re nata regimen for initiating and continuing ranibizumab therapy for patients with wet AMD. The comprehensive spectrum of issues related to implementation of the regimen is covered qualitatively in ten didactic topics provided by a group of clinicians with direct experience of this regimen in their department. The topics include definition, new and previously treated eyes, management of high-frequency injections, maximum extensions, discontinuing T&E, bilateral cases, clerical, audit, and patient counseling. This article aims to provide a useful resource for the implementation of the T&E regimen. A quantitative summary of the visual outcomes in key publications is also provided in this article. This article should be a valuable resource for staff training.

Purpose To assess the safety of nurse-led services of intravitreal injection of dexamethasone implant. Methods An audit of intravitreal injection of dexamethasone implant service in our unit revealed a significant delay in the delivery of injection from the time a clinical decision was made. The limiting factors were an inadequate number of injectors and limited capacity. The constraint in capacity was addressed by moving the service from the theatre to the cleanroom in the outpatients setting. Two senior nurse practitioners in the existing pool of injectors, experienced in intravitreal anti-VEGF injection, were trained to deliver the intravitreal dexamethasone implant service. A safety audit was carried out after they had completed 1000 cases. Results The nurse practitioners administered 1006 injections from February 2017 to October 2019. There was no case of endophthalmitis (0%) or other visually significant complications like retinal detachment, vitreous haemorrhage, hypotony or iatrogenic cataract. One patient had incomplete scleral penetration of the implant, but this resolved without any sequelae. The waiting time to inject the implant nearly halved from 29.5 to 15 days in the nurse-led service. A patient satisfaction survey was overwhelmingly positive, with the majority advocating for the continuation of the nurse-led service. Conclusion The current cohort of experienced nurses providing anti-VEGF injections can be trained under supervision to inject the intravitreal dexamethasone implant (Ozurdex). This is safe, additionally effective in streamlining the service and reducing the waiting time for delivery of the steroid implant.

A satellite symposium, chaired by Usha Chakravarthy, was held at the Royal College of Ophthalmologists Annual Congress in Birmingham, entitled Managing Insufficiently Responsive DMO Patients Post-NICE Guidance. While therapies targeting vascular endothelial growth factor (VEGF), such as ranibizumab, have proven benefit in the treatment of diabetic macular oedema (DMO), patients with disease of longer duration may not respond as well to these therapies, a result of the more complex pathophysiology of chronic DMO, involving retinal inflammation. Corticosteroids offer a multi-factorial treatment approach, acting on numerous biochemical and anatomical pathways, unlike ranibizumab and bevacizumab, which inhibit VEGF and consequently confer their benefits through the modification of a single pathway. The ILUVIEN® intravitreal implant, contains 190 μg of fluocinolone acetonide (FAc), with an average release rate of 0.2 μg/ day for up to 36 months. Its benefits are most pronounced in patients with chronic DMO. ILUVIEN is indicated for the treatment of vision impairment associated with chronic DMO, considered insufficiently responsive to available therapies. The effectiveness of ILUVIEN was demonstrated in phase III clinical trials, and these benefits are being replicated in routine clinical practice. In this symposium, the speakers described clinical scenarios that demonstrated the utility of ILUVIEN in patients with DMO that are insufficiently responsive to currently available first-line therapies.

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.
