Summary: The study investigated cytokine and chemokines profiling in the aqueous humor of nAMD patients, finding lower levels of basic fibroblast growth factor and RANTES, and higher levels of VEGF-A compared to the control group. After IVR treatment, levels of Eotaxin increased while VEGF-A decreased in nAMD patients.

Summary: Monthly alternating injections of aflibercept and bevacizumab were effective in preventing deterioration in patients with neovascular age-related macular degeneration who were not responding to bimonthly injections.

Summary: This study revealed a trend in the selection of ranibizumab and aflibercept for initial treatment of neovascular AMD and PCV, with ranibizumab preferred in older patients and those with type 3 MNV, and aflibercept highly preferred in patients with PCV. The variance in patient characteristics and efficacy of the two agents may have influenced this trend.

Summary: This study aimed to evaluate the efficacy changes of stable nAMD patients on aflibercept who switched to ranibizumab. The results showed that patients in the switch group experienced worsening of visual acuity and central foveal thickness, while those in the aflibercept group remained relatively stable.

Summary: A study found that aflibercept may reduce the number of anti-VEGF treatments and increase the likelihood of weaning off medication compared to bevacizumab for patients with nvAMD. Therefore, the choice of therapy is crucial when treating patients with nvAMD.

Summary: Age-related macular degeneration (AMD) is a leading cause of irreversible central vision loss in the elderly and is associated with abnormal blood vessel growth. This study explored the relationship between the protease Granzyme B (GzmB) and the antiangiogenic factors Thrombospondin (TSP)-1 and TSP-2 in eyes with neovascular AMD. The study found that TSP-1 and TSP-2 are substrates of GzmB and that the proteolysis of these factors by GzmB may contribute to neovascular AMD-related choroidal neovascularization (CNV).

Summary: Age-related macular degeneration is becoming increasingly important due to aging populations and increased longevity. It affects individuals older than 55 years and threatens high-acuity central vision needed for important tasks. Advances in retinal imaging have identified biomarkers of progression. New treatments for neovascular AMD offer potentially longer-lasting effects, but a treatment for atrophic late-stage AMD is still being developed. An effective intervention for early-stage disease or prevention of late-stage AMD has not been found yet, and our understanding of underlying mechanisms continues to evolve.

Summary: The study found that during the development of CNV, there is a significant increase in choroidal thickness in the corresponding subfield. Additionally, three months before the development of CNV, the choroidal thickness in the central subfield also significantly increases. Regular measurement of choroidal thickness may help in predicting CNV development.

Summary: The study found that intravitreal ziv-aflibercept (IVZ) is associated with significant improvement in best-corrected visual acuity (BCVA) and reduction in central macular thickness (CMT) in patients with diabetic macular edema (DME).

Summary: The study found that using aflibercept monotherapy is as effective as combining PDT with ranibizumab in treating PCV patients, with better prognosis observed in non-pachychoroid patients.

Summary: AMD is a major cause of blindness worldwide, with neovascular AMD leading to vision loss. The current standard of care with anti-angiogenic agents is only effective in around 50% of AMD cases. Studies have shown that Rac1 activation plays a crucial role in the invasion of choroidal endothelial cells into the neural retina in AMD.

Summary: The study reported the age-standardized annual incidence of blindness due to AMD and the treatment patterns in Australia. The incidence of blindness rose during the PDT era but declined in the IVT era. The age at AMD blindness registration increased over time, with different trends in PDT and IVT usage.

Summary: This study evaluated choroidal vascular changes in nAMD patients treated with aflibercept injections, showing significant decreases in choroidal thickness and vascularity after treatment, which were significantly correlated with baseline choroidal vascularity index.

Summary: Age-related macular degeneration (AMD) is a leading cause of irreversible blindness in adults, with significant visual disability and central vision loss. Adiponectin (APN) and its receptors (AdipoRs) play a central role in metabolic disorders and ocular pathology. This review summarizes the association of APN/AdipoRs with retinal diseases, specifically AMD and diabetic retinopathy, and presents original research on the inhibition of choroidal neovascularization (CNV) in a mouse model with APN-derived peptides.

Summary: The relative efficacy of administering aflibercept monotherapy compared with bevacizumab followed by aflibercept if there is insufficient improvement in eyes with diabetic macular edema is uncertain.
