Abstract
Neovascular age-related macular degeneration (nARMD) is an important cause of visual impairment and blindness in the elderly, with choroidal neovascularization in the macula as the main pathological feature. The onset of nARMD is closely related to factors including age, oxidative stress, and lipid metabolism. Vascular endothelial growth factor (VEGF) is an important factor contributing to nARMD as well as choroidal neovascularization and retinal leakage formation. At present, anti-VEGF therapy is the only treatment that improves vision and halts disease progression in most patients, making anti-VEGF drugs a landmark development for nARMD treatment. Although intravitreal injection of anti-VEGF drugs has become the first-line treatment for nARMD, this treatment has many shortcomings including repeated injections, poor or no response in some patients, and complications such as retinal fibrosis. As a result, several new anti-VEGF drugs are being developed. This review provides a discussion of these new anti-VEGF drugs for the treatment of nARMD.

Macular Neovascularization Type Influence on Anti-VEGF Intravitreal Therapy Outcomes in Age-Related Macular Degeneration. Ophthalmol Retina 2024; 8:350-359. [PMID: 37924946 DOI: 10.1016/j.oret.2023.10.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 10/27/2023] [Accepted: 10/27/2023] [Indexed: 11/06/2023]
Abstract
PURPOSE To evaluate the influence of macular neovascularization (MNV) lesion type on 12-month clinical outcomes in treatment-naive eyes with neovascular age-related macular degeneration (nAMD) treated with anti-VEGF drugs nationwide. DESIGN Multicenter national nAMD database observational study. SUBJECTS One thousand six hundred six treatment-naive nAMD eyes (1330 patients) undergoing anti-VEGF therapy for 12 months nationwide. METHODS Demographics, visual acuity (VA) in logarithm of the minimum angle of resolution letters, number of injections and visits were was collected using a validated web-based tool. Neovascular lesion phenotype was classified as type 1 (T1, n = 711), type 2 (T2, n = 505), type 3 (T3, n = 315), and aneurysmal type 1 (A-T1, n = 75), according to the new proposed consensus classification. MAIN OUTCOME MEASURES Mean VA change at 12 months, final VA at 12 months, number of injections, time to lesion inactivation. RESULTS A total of 1606 treatment-naive nAMD eyes (1330 patients) received a median of 7 injections over 12 months. Mean (± standard deviation) baseline VA was significantly lower for T2 (49.4 ± 23.5 letters) compared with T1 (57.8 ± 20.8) and T3 (58.2 ± 19.4) (both P < 0.05) lesions. Mean VA change at 12 months was significantly greater for A-T1 (+9.5 letters) compared with T3 (+3.1 letters, P < 0.05). Patients with T3 lesions had fewer active visits (24.9%) than those with other lesion types (T1, 30.5%; T2, 32.6%; A-T1, 27.5%; all P < 0.05). Aflibercept was the most used drug in A-T1 lesions (70.1%) and ranibizumab in T1 (40.7%), T2 (57.7%), and T3 (47.6%) lesions. CONCLUSIONS This study highlights the relevance of MNV type on clinical outcomes in nAMD and reports significant differences in baseline VA, VA change, and lesion activity at 12 months. This report provides data about lesion-specific clinical features, which may guide the management of nAMD cases and potentially support personalized clinical decision making for these patients.

Ophthalmol Ther 2022; 11:1503-1516.

Abstract
INTRODUCTION To evaluate the outcomes of intravitreal aflibercept injections for retinal angiomatous proliferation (RAP) according to disease stage. METHODS This retrospective chart review included 68 eyes of 53 individuals diagnosed as having RAP and 109 neovascular age-related macular degeneration (nAMD) eyes of 109 patients as controls. All patients received intravitreal injections of aflibercept in a real-world setting. The main outcome measures were the changes in the mean of best-corrected visual acuity (BCVA) and central retinal thickness (CRT) as well as the total number of injections received during the 3-year follow-up period. RESULTS The average BCVA and CRT changes in eyes affected by RAP and the controls at 3 years were non-significant. Both populations received a similar number of injections. After 3 years of treatment, patients with RAP had visual decline despite stable anatomical outcomes. Approximately 50% of the eyes with stage II RAP exhibited significant BCVA decline at the end of the third year. Among those eyes that had deteriorated BCVA, persistently worsening BCVA and thinning CRT were observed from year 2 to year 3. CONCLUSION Similar to treating nAMD, intensive injections or aggressive treatment strategies are required to treat RAP to achieve optimal visual outcomes in a real-world setting. The response to aflibercept treatment at the second year is associated with the final visual outcome of eyes with stage II RAP lesions.

Abstract
BACKGROUND OCT angiography (OCT-A) allows non-invasive blood flow registration of the retina and choroid. In contrast to fluorescein angiography (FA), no dye has to be administered. The OCT-A also provides depth-selective information. OCT-A and FA were compared in patients with neovascular age-related macular degeneration (AMD) with retinal angiomatous proliferation (RAP) stage 1. In stage 1, the neovascularizations are intraretinal. In contrast to the two-dimensional total image of the FA, the OCT-A allows a depth-selective display of the individual retinal layers. In this way, a conclusion can be drawn about the place of origin of the RAP. PATIENTS AND METHODS Three patients with neovascular AMD and RAP stage 1 were included. They were examined with OCT (ZEISS CIRRUS HD-OCT 5000, Carl Zeiss Meditec, Inc., Dublin, USA), OCT-A (ZEISS AngioPlex OCT-Angiography) as well as FA (HRA2, Heidelberg Engineering) between January 2016 and March 2019. A complete ophthalmological examination was performed. A qualitative analysis of the OCT-A images (3 × 3 and 6 × 6 mm) and the FA images was carried out. Leaks in the FA were compared with the en-face images of the OCT-A followed by a depth-selective assignment using the corresponding B-scans of the OCT-A. RESULTS It was one woman and two men aged 66 - 89 years. The visual acuity was 0.4 in the first, 0.5 p in the second and 0.8 in the third patient. The diagnosis of RAP stage 1 could be made both in the OCT, the FA and the OCT-A. All patients showed macular edema in the OCT. The FA showed selective hyperfluorescence in the early phase and fluorescein extravasation in the late phase. In OCT-A, the blood flow in all patients could be shown in the hyperreflective structure of the RAP in the B-scan. The first patient showed two RAP lesions in the FA, which were in the deep vascular plexus in the OCT-A. In the second patient, three RAP lesions were found in the FA, and a total of five RAP lesions in the OCT-A. One could be located in the superficial and deep vascular plexus, four in the deep vascular plexus. The third patient showed one RAP lesion in the FA as well as in the OCT-A, which could be assigned to the superficial vascular plexus. CONCLUSION The OCT-A is well suited for the diagnosis of RAP stage 1. In the present cases, the diagnosis in the OCT-A could be made as clearly as by FA. A major advantage of the OCT-A results from the non-invasive character and the depth selectivity. The RAP 1 lesions could be assigned to both the superficial and the deep vascular plexus. Depth selection is not possible with the FA due to the summary picture.
