UNASSIGNED: Despite widespread availability and consensus on its advantages for detailed imaging of geographic atrophy (GA), spectral-domain optical coherence tomography (SD-OCT) might benefit from automated quantitative OCT analyses in GA diagnosis, monitoring, and reporting of its landmark clinical trials.
UNASSIGNED: To analyze the association between pegcetacoplan and consensus GA SD-OCT end points.
UNASSIGNED: This was a post hoc analysis of 11 614 SD-OCT volumes from 936 of the 1258 participants in 2 parallel phase 3 studies, the Study to Compare the Efficacy and Safety of Intravitreal APL-2 Therapy With Sham Injections in Patients With Geographic Atrophy (GA) Secondary to Age-Related Macular Degeneration (OAKS) and Study to Compare the Efficacy and Safety of Intravitreal APL-2 Therapy With Sham Injections in Patients With Geographic Atrophy (GA) Secondary to Age-Related Macular Degeneration (DERBY). OAKS and DERBY were 24-month, multicenter, randomized, double-masked, sham-controlled studies conducted from August 2018 to July 2020 among adults with GA with total area 2.5 to 17.5 mm2 on fundus autofluorescence imaging (if multifocal, at least 1 lesion ≥1.25 mm2). This analysis was conducted from September to December 2023.
UNASSIGNED: Study participants received pegcetacoplan, 15 mg per 0.1-mL intravitreal injection, monthly or every other month, or sham injection monthly or every other month.
UNASSIGNED: The primary end point was the least squares mean change from baseline in area of retinal pigment epithelium and outer retinal atrophy in each of the 3 treatment arms (pegcetacoplan monthly, pegcetacoplan every other month, and pooled sham [sham monthly and sham every other month]) at 24 months. Feature-specific area analysis was conducted by Early Treatment Diabetic Retinopathy Study (ETDRS) regions of interest (ie, foveal, parafoveal, and perifoveal).
UNASSIGNED: Among 936 participants, the mean (SD) age was 78.5 (7.22) years, and 570 participants (60.9%) were female. Pegcetacoplan, but not sham treatment, was associated with reduced growth rates of SD-OCT biomarkers for GA for up to 24 months. Reductions vs sham in least squares mean (SE) change from baseline of retinal pigment epithelium and outer retinal atrophy area were detectable at every time point from 3 through 24 months (least squares mean difference vs pooled sham at month 24, pegcetacoplan monthly: -0.86 mm2; 95% CI, -1.15 to -0.57; P < .001; pegcetacoplan every other month: -0.69 mm2; 95% CI, -0.98 to -0.39; P < .001). This association was more pronounced with more frequent dosing (pegcetacoplan monthly vs pegcetacoplan every other month at month 24: -0.17 mm2; 95% CI, -0.43 to 0.08; P = .17). Stronger associations were observed in the parafoveal and perifoveal regions for both pegcetacoplan monthly and pegcetacoplan every other month.
UNASSIGNED: These findings offer additional insight into the potential effects of pegcetacoplan on the development of GA, including potential effects on the retinal pigment epithelium and photoreceptors.
UNASSIGNED: ClinicalTrials.gov Identifiers: NCT03525600 and NCT03525613.

OBJECTIVE: To assess the methodological quality of Clinical Practice Guidelines (CPG) for the diagnosis and management of Retinal Vein Occlusion (RVO).
METHODS: A systematic review of CPGs for the diagnosis and management of RVO was carried out with a search in databases, metasearch engines, CPG development institutions, ophthalmology associations and CPG repositories until April 2022. Search update was performed on April 2023, with no new record available. Five CPGs published in the last 10 years in English/Spanish were selected, and 5 authors evaluated them independently, using the Appraisal of Guidelines for Research and Evaluation (AGREE-II) instrument. An individual assessment of each CPG by domain (AGREE-II), an overall assessment of the guide, and its use with or without modifications were performed. Additionally, a meta-synthesis of the recommendations for the most relevant outcomes was carried out.
RESULTS: The lowest score (mean 18.8%) was for domain 5 \'applicability\', and the highest score (mean 62%) was for domain 4 \'clarity of presentation\'. The 2019 American guideline (PPP) presented the best score (40.4%) in domain 3 \'rigour of development\'. When evaluating the overall quality of the CPGs analysed, all CPGs could be recommended with modifications. In the meta-synthesis, anti-VEGF therapy is the first-choice therapy for macular oedema associated with RVO, but there is no clear recommendation about the type of anti-VEGF therapy to choose. Recommendations for diagnosis and follow-up are similar among the CPGs appraised.
CONCLUSIONS: Most CPGs for the diagnosis and management of RVO have a low methodological quality assessed according to the AGREE-II. PPP has the higher score in the domain \'rigour of development\'. Among the CPGs appraised, there is no clear recommendation on the type of anti-VEGF therapy to choose.

Central serous chorioretinopathy (CSC) is a relatively common disease that causes vision loss due to macular subretinal fluid leakage and it is often associated with reduced vision-related quality of life. In CSC, the leakage of subretinal fluid through defects in the retinal pigment epithelial layer\'s outer blood-retina barrier appears to occur secondary to choroidal abnormalities and dysfunction. The treatment of CSC is currently the subject of controversy, although recent data obtained from several large randomized controlled trials provide a wealth of new information that can be used to establish a treatment algorithm. Here, we provide a comprehensive overview of our current understanding regarding the pathogenesis of CSC, current therapeutic strategies, and an evidence-based treatment guideline for CSC. In acute CSC, treatment can often be deferred for up to 3-4 months after diagnosis; however, early treatment with either half-dose or half-fluence photodynamic therapy (PDT) with the photosensitive dye verteporfin may be beneficial in selected cases. In chronic CSC, half-dose or half-fluence PDT, which targets the abnormal choroid, should be considered the preferred treatment. If PDT is unavailable, chronic CSC with focal, non-central leakage on angiography may be treated using conventional laser photocoagulation. CSC with concurrent macular neovascularization should be treated with half-dose/half-fluence PDT and/or intravitreal injections of an anti-vascular endothelial growth factor compound. Given the current shortage of verteporfin and the paucity of evidence supporting the efficacy of other treatment options, future studies-ideally, well-designed randomized controlled trials-are needed in order to evaluate new treatment options for CSC.

Together with diabetic retinopathy, diabetic macular edema (DME) ranks among the most common causes of severe loss of vision in working adults. Due to recent developments in imaging methods, new classification schemes of DME have been created. In addition to this, new treatment options have been introduced (new intravitreal drugs as well as treatment protocols). At the same time laser, surgical as well as combination therapy is still available. In this paper we evaluate the current knowledge about DME diagnostic and treatment options and formulate recommended guidelines for the management of DME.

BACKGROUND: Retinal diseases, including wet or dry age-related macular degeneration, diabetic macular edema, and diabetic retinopathy (DR), are underdiagnosed and undertreated in the United States. Clinical trials support the effectiveness of anti-vascular endothelial growth factor (anti-VEGF) therapies for several retinal conditions, but real-world data suggest underuse by clinicians, resulting in patients experiencing poorer visual outcomes over time. Continuing education (CE) has demonstrated effectiveness at changing practice behaviors, but more research is needed to understand whether CE can help address diagnostic and treatment gaps.
METHODS: This test and control matched pair analysis examined pre-/post-test knowledge of retinal diseases and guideline-based screening and intervention among 10,786 healthcare practitioners (i.e., retina specialists, ophthalmologists, optometrists, primary care providers, diabetes educators, pharmacists/managed care specialists, and other healthcare providers, such as registered nurses, nurse practitioners, and physician assistants) who participated in a modular, interactive CE initiative. An additional medical claims analysis provided data on practice change, evaluating use of VEGF-A inhibitors among retina specialist and ophthalmologist learners (n = 7,827) pre-/post-education, compared to a matched control group of non-learners. Outcomes were pre-/post-test change in knowledge/competence and clinical change in application of anti-VEGF therapy, as identified by the medical claims analysis.
RESULTS: Learners significantly improved knowledge/competence scores on early identification and treatment, identifying patients who could benefit from anti-VEGF agents, using guideline-recommended care, recognizing the importance of screening and referral, and recognizing the importance of early detection and care for DR (all P-values = 0.003 to 0.004). Compared with matched controls, learners\' incremental total injections for anti-VEGF agents for retinal conditions increased more after the CE intervention (P < 0.001); specifically, there were 18,513 more (new) anti-VEGF injections prescribed versus non-learners (P < 0.001).
CONCLUSIONS: This modular, interactive, immersive CE initiative resulted in significant knowledge/competence gains among retinal disease care providers and changes in practice-related treatment behaviors (i.e., appropriate consideration and greater incorporation of guideline-recommended anti-VEGF therapies) among participating ophthalmologists and retina specialists compared to matched controls. Future studies will utilize medical claims data to show longitudinal impact of this CE initiative on treatment behavior among specialists and impact on diagnosis and referral rates among optometrists and primary care providers who participate in future programming.

Background In mainland China, patients with neovascular age-related macular degeneration (nAMD) have approximately an 40% prevalence of polypoidal choroidal vasculopathy (PCV). This disease leads to recurrent retinal pigment epithelium detachment (PED), extensive subretinal or vitreous hemorrhages, and severe vision loss. China has introduced various treatment modalities in the past years and gained comprehensive experience in treating PCV.Methods A total of 14 retinal specialists nationwide with expertise in PCV were empaneled to prioritize six questions and address their corresponding outcomes, regarding opinions on inactive PCV, choices of anti-vascular endothelial growth factor (anti-VEGF) monotherapy, photodynamic therapy (PDT) monotherapy or combined therapy, patients with persistent subretinal fluid (SRF) or intraretinal fluid (IRF) after loading dose anti-VEGF, and patients with massive subretinal hemorrhage. An evidence synthesis team conducted systematic reviews, which informed the recommendations that address these questions. This guideline used the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach to assess the certainty of evidence and grade the strengths of recommendations. Results The panel proposed the following six conditional recommendations regarding treatment choices. (1) For patients with inactive PCV, we suggest observation over treatment. (2) For treatment-na?ve PCV patients, we suggest either anti-VEGF monotherapy or combined anti-VEGF and PDT rather than PDT monotherapy. (3) For patients with PCV who plan to initiate combined anti-VEGF and PDT treatment, we suggest later/rescue PDT over initiate PDT. (4) For PCV patients who plan to initiate anti-VEGF monotherapy, we suggest the treat and extend (T&E) regimen rather than the pro re nata (PRN) regimen following three monthly loading doses. (5) For patients with persistent SRF or IRF on optical coherence tomography (OCT) after three monthly anti-VEGF treatments, we suggest proceeding with anti-VEGF treatment rather than observation. (6) For PCV patients with massive subretinal hemorrhage (equal to or more than four optic disc areas) involving the central macula, we suggest surgery (vitrectomy in combination with tissue-plasminogen activator (tPA) intraocular injection and gas tamponade) rather than anti-VEGF monotherapy. Conclusions Six evidence-based recommendations support optimal care for PCV patients\' management.

Age-related macular degeneration (AMD) is the main cause of low vision and even blindness in the elderly. With the aging of our population, the number of AMD patients will continue to rise. In the past decade, the rapid development of ocular fundus imaging technology has provided a new perspective and approach for the classification, diagnosis and follow-up of AMD. The advent of new drugs has provided more diverse intervention and treatment methods for AMD, especially for neovascular AMD, and the emphasis on accurate and individualized treatment has put forward higher requirements for retinal specialists. Therefore, based on the latest evidence-based medical information, combined with the international guidelines and the current situation of China\'s social and economic development, experts from the Chinese Vitreo-Retinal Society of Chinese Medical Association, the Fundus Disease Group of Chinese Ophthalmologist Association, and the National Clinical Research Center for Eye Diseases gave recommendations around eight clinical problems and formed China\'s guidelines for the clinical diagnosis and treatment of AMD. With the implementation of these guidelines, we can standardize the diagnosis, treatment, prevention and follow-up of AMD in China.

Brolucizumab has high efficacy in retinal fluid resolution and provides the possibility for longer dosing intervals in the treatment of neovascular age-related macular degeneration. However, brolucizumab has been associated with events of retinal vasculitis and retinal vascular occlusion typically in the presence of other signs of intraocular inflammation (IOI). The purpose of this report is to provide guidance on the use of brolucizumab for neovascular age-related macular degeneration to a global audience.
A literature review was conducted on adverse events related to IOI after administration of brolucizumab in eyes with neovascular age-related macular degeneration.
Possible risk factors for IOI and retinal vascular occlusion after brolucizumab should be considered before administering brolucizumab. Patients who receive brolucizumab should be educated on the symptoms, signs, and time course of IOI after brolucizumab. Before each injection of brolucizumab, physicians should assess the eye for any signs of inflammation and not treat with brolucizumab if inflammation is detected. Treatment of IOI should be prompt and provided with particular attention to the posterior segment.
Careful patient selection, patient education, assessment for inflammation, and intensive treatment of possible inflammation are important when using brolucizumab in patients with neovascular age-related macular degeneration.

In Asians, polypoidal choroidal vasculopathy (PCV) is becoming more widely recognized as a significant cause of exudative maculopathy. The previous set of Indian guidelines on the management of PCV were published in 2018, with a literature search updated up to November 2015. As the treatment of PCV evolves, retinal physicians must constantly modify their current practice. The current guidelines are based on the most up-to-date information on PCV and are an update to the previous set of guidelines. These guidelines were developed by a panel of Indian retinal experts under the aegis of the Vitreoretinal Society of India (VRSI), based on a comprehensive search and assessment of literature up to September 2021. The final guidelines i) provide the updated nomenclature in PCV; ii) discusses the newer diagnostic imaging features of PCV, especially in the absence of indocyanine green angiography (ICGA); and iii) recommends the best possible therapeutic approach in the management of PCV, including the choice of anti-vascular endothelial growth factor (anti-VEGF) agents, treatment regimen, and the role of switching between the anti-VEGF agents. In the face of non-availability of photodynamic therapy (PDT) in India, we constructed practical recommendations on anti-VEGF monotherapy in PCV. The current updated recommendations would provide a broader framework to the treating retinal physician for the diagnosis and management of PCV for optimal therapeutic outcomes.
