Age-related macular degeneration as the major cause of blindness in the elderly population has remained at the epicenter of clinical research in ophthalmology. This retinal disorder is characterized by the photoreceptor and retinal pigment epithelial cells loss, occurring within the macula. The disease represents a spectrum of clinical manifestations. It is a multifactorial disease resulting from a combination of genetic predispositions and environmental risk factors. AMD is classified into two different types, dry and wet. Wet AMD is in close relation with angiogenesis and inflammatory processes.A variety of anti-angiogenesis and anti-inflammatory drugs have been proposed for the treatment of the disease. The purpose of this paper is to briefly review the pharmacological therapies of the wet form of AMD and focus on new drugs that are currently in different stages of research and development.

Objective: To evaluate the impact of evolving treatment paradigms for neovascular age-related macular degeneration (nAMD) by comparing outcomes between two patient cohorts treated with different anti-vascular endothelial growth factor (anti-VEGF) regimens over a decade apart.
Methods: This retrospective cohort study included 200 treatment-naive nAMD patients divided into two cohorts. Cohort 1 (2009-2010) was treated with a pro re nata (PRN) regimen, involving three initial monthly injections followed by as-needed treatments based on monthly monitoring.

Self-renewal capacity and potential to differentiate into almost any cell type of the human body makes pluripotent stem cells a valuable starting material for manufacturing of clinical grade cell therapies. Neurodegenerative diseases are characterized by gradual loss of structure or function of neurons, often leading to neuronal death. This results in gradual decline of cognitive, motor, and physiological functions due to the degeneration of the central nervous systems.

RNA methylation is a pivotal epigenetic modification that adjusts various aspects of RNA biology, including nuclear transport, stability, and the efficiency of translation for specific RNA candidates. The methylation of RNA involves the addition of methyl groups to specific bases and can occur at different sites, resulting in distinct forms, such as N6-methyladenosine (mA), N1-methyladenosine (mA), 5-methylcytosine (mC), and 7-methylguanosine (mG). Maintaining an optimal equilibrium of RNA methylation is crucial for fundamental cellular activities such as cell survival, proliferation, and migration.

Purpose: Color imaging is the accepted reference standard for detection of macular fibrosis in neovascular age-macular degeneration. Other imaging modalities of fluorescein angiography (FA) and spectral domain optical coherence tomography (SD-OCT) are also used but no formal agreement studies exist. We evaluated the agreement between fibrosis on colour, FA and SD-OCT-detected hyperreflective material (HRM) and their clinical relevance.

Age-related retinal degeneration is associated with mitochondrial dysfunction. Emerging evidence suggests that photobiomodulation therapy (PBMT) using near-infrared light may improve mitochondrial function and visual performance, but its efficacy is critically time-dependent. This article explores how daily biological rhythms and mitochondrial function interact, focusing on the potential of timed PMBT for age-related eye diseases.
