Age-related macular degeneration (AMD) is a chronic multifactorial degenerative eye disease and one of the leading causes of irreversible blindness worldwide. Despite extensive research, there is no consensus on the predominant pathological mechanism leading to photoreceptor death. AMD is associated with molecular and cellular disruptions that ultimately result in photoreceptor degeneration. This review summarizes data from international and Russian studies on the pathophysiological mechanisms underlying the development and progression of photoreceptor degeneration, presents scientific developments in therapeutic correction of these disturbances, and highlights promising avenues for pharmacological retinal neuroprotection that require further validation in clinical studies.

In this article, we discuss Ye 's recent article on the association between age at diabetes diagnosis and subsequent risk of age-related ocular diseases. The study, which utilized United Kingdom Biobank data, highlighted a strong link between early diabetes onset and major eye conditions, such as cataracts, glaucoma, age-related macular degeneration, and vision loss, independent of glycemic control and disease duration. This finding challenges the previous belief that diabetic eye disease primarily correlates with hyperglycemia.

Photodynamic therapy (PDT) is a treatment modality clinically approved for several oncologic indications, including esophageal and endobronchial cancers, precancerous conditions including Barrett's esophagus and actinic keratosis, and benign conditions like age-related macular degeneration. While it is currently clinically underused, PDT is an area of significant research interest. Because PDT relies on the absorption of light energy by intrinsic or administered absorbers, the dosimetric quantity of interest is the absorbed energy per unit mass of tissue, proportional to the fluence rate of light in tissue.

Purpose: The retinal pigment epithelium (RPE) plays an important role in the pathogenesis of age-related macular degeneration (AMD) and other retinal degenerative diseases. The introduction of healthy RPE cell cultures into the subretinal space offers a potential treatment strategy. The aim of this study was the long-term culture and characterisation of RPE cells on nanofiber scaffolds.

Background: Glaucoma, diabetic retinopathy, and age-related macular degeneration impose substantial economic burdens on healthcare systems due to their high prevalence and chronic nature. Nevertheless, comprehensive Italian data is limited. This study aims to collect Italian evidence on the economic impact of these conditions to support more effective healthcare planning.
