Anti-vascular endothelial growth factor monotherapy or combined with verteporfin photodynamic therapy for retinal angiomatous proliferation: a systematic review with meta-analysis. Front Pharmacol 2023; 14:1141077. [PMID: 37377929 PMCID: PMC10291099 DOI: 10.3389/fphar.2023.1141077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Accepted: 05/19/2023] [Indexed: 06/29/2023] Open
Abstract
Purpose: To assess functional and anatomical outcomes of intravitreal anti-Vascular Endothelial Growth Factor (anti-VEGF) monotherapy versus combined with verteporfin Photodynamic Therapy (PDT) for Retinal Angiomatous Proliferation (RAP). Methods: Studies reporting outcomes of intravitreal anti-VEGF monotherapy and/or in combination with verteporfin PDT in RAP eyes with a follow-up ≥ 12 months were searched. The primary outcome was the mean change in best corrected visual acuity (BCVA) at 12 months. Mean change in central macular thickness (CMT) and mean number of injections were considered as secondary outcomes. The mean difference (MD) between pre- and post-treatment values was calculated along with 95% Confidence Interval (95% CI). Meta-regressions were performed to assess the influence of anti-VEGF number of injections on BCVA and CMT outcomes. Results: Thirty-four studies were included. A mean gain of 5.16 letters (95% CI = 3.30-7.01) and 10.38 letters (95% CI = 8.02-12.75) was shown in the anti-VEGF group and combined group, respectively (anti-VEGF group vs. combined group, p < 0.01). A mean CMT reduction of 132.45 µm (95% CI = from -154.99 to -109.90) and 213.93 µm (95% CI = from -280.04 to -147.83) was shown in the anti-VEGF group and combined group, respectively (anti-VEGF group vs. combined group, p < 0.02). A mean of 4.9 injections (95% CI = 4.2-5.6) and 2.8 injections (95% CI = 1.3-4.4) were administered over a 12-month period in the anti-VEGF group and combined group, respectively. Meta-regression analyses showed no influence of injection number on visual and CMT outcomes. High heterogeneity was found across studies for both functional and anatomical outcomes. Conclusion: A combined approach with anti-VEGF and PDT could provide better functional and anatomical outcomes in RAP eyes compared with anti-VEGF monotherapy.

Abstract
Type 3 macular neovascularization (MNV3), or retinal angiomatous proliferation (RAP), is a distinct type of neovascular age-related macular degeneration (AMD), which is a leading cause of vision loss in older persons. During the past decade, systematic investigation into the clinical, multimodal imaging, and histopathological features and therapeutic outcomes has provided important new insight into this disease. These studies favor the retinal origin of MNV3 and suggest the involvement of retinal hypoxia, inflammation, von Hippel–Lindau (VHL)–hypoxia-inducible factor (HIF)–vascular endothelial growth factor (VEGF) pathway, and multiple cell types in the development and progression of MNV3. Several mouse models, including the recently built Rb/p107/Vhl triple knockout mouse model by our group, have induced many of the histological features of MNV3 and provided much insight into the underlying pathological mechanisms. These models have revealed the roles of retinal hypoxia, inflammation, lipid metabolism, VHL/HIF pathway, and retinoblastoma tumor suppressor (Rb)–E2F cell cycle pathway in the development of MNV3. This article will summarize the clinical, multimodal imaging, and pathological features of MNV3 and the diversity of animal models that exist for MNV3, as well as their strengths and limitations.

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.

Abstract
Age-related macular degeneration is an acquired degenerative disease that is responsible for severe loss of vision in elderly people. There are two types: dry age-related macular degeneration and wet age-related macular degeneration. Its treatment has been improved and tries to be tailored in the future. The aim of this review is to summarize the pharmacological advances in the treatment of age-related macular degeneration. Regarding dry AMD, there is no effective treatment to reduce its progression. However, some molecules such as lampalizumab and eculizumab were under investigation, although they have shown low efficacy. Herein, in an attempt to prevent dry AMD progression, the most important studies suggested increasing the antioxidants intake and quitting the smoke habit. On the other hand, wet AMD has more developed treatment. Nowadays, the gold standard treatment is anti-VEGF injections. However, more effective molecules are currently under investigation. There are different molecules under research for dry AMD and wet AMD. This fact could help us treat our patients with more effective and lasting drugs but more clinical trials and safety studies are required in order to achieve an optimal treatment.
