Purpose: Because there are few epidemiologic data examining the relationship between alcohol use and age-related maculopathy, we investigated this relationship via the population-based Beaver Dam Eye Study.
Methods: Alcohol consumption in the year before examination was determined by a standardized questionnaire. Age-related maculopathy status was determined by grading stereoscopic color fundus photographs.
Results: While controlling for other factors, consumption of beer in the past year was related to greater odds of increased retinal pigment degeneration (odds ratio, 1.13; 95% confidence interval, 1.02, 1.25) and exudative macular degeneration (odds ratio, 1.41; 95% confidence interval, 1.05, 1.88). Current consumption of neither wine nor liquor was related to early or late age-related maculopathy.
Conclusions: These data suggest a relationship between beer consumption and greater odds of having exudative macular degeneration. Whether this is from a toxic effect specific to beer or from other unknown confounders cannot be determined.

Purpose: To investigate the effect of Ca2+/calmodulin-dependent protein kinase II (CAMKII) δ subtypes (CAMK2D) on sodium iodate (NaIO3)-induced retinal degeneration in mice.
Methods: Bioinformatics analysis and Western blot experiments were used to screen the significantly differentially expressed genes in age-related macular degeneration (AMD) disease. CAMK2D knockdown and overexpression models were constructed by lentivirus (LV) infection of adult retinal pigment epithelial cell line-19 (ARPE-19) cells in vitro.

Comprehensive multimodal imaging is essential for the precise clinical diagnostics of neovascular age-related macular degeneration (nAMD). Noninvasive optical coherence tomography (OCT) is of prime importance regarding the baseline examination, follow-up and monitoring during treatment. The OCT imaging in nAMD eyes enables a high-resolution assessment of the retinal micromorphology, which can be considerably disturbed in different layers.

Epithelial-to-mesenchymal transition (EMT) is a critical and complex process involved in normal embryonic development, tissue regeneration, and tumor progression. It also contributes to retinal diseases, such as age-related macular degeneration (AMD) and proliferative vitreoretinopathy (PVR). Although absent in melanoma 2 (AIM2) has been linked to inflammatory disorders, autoimmune diseases, and cancers, its role in the EMT of the retinal pigment epithelium (RPE-EMT) and retinal diseases remains unclear.

The outer retina (OR) is highly energy demanding. Impaired energy metabolism combined with high demands are expected to cause energy insufficiencies that make the OR susceptible to complex blinding diseases such as age-related macular degeneration (AMD). Here, anatomical, physiological and quantitative molecular data were used to calculate the ATP expenditure of the main energy-consuming processes in three cell types of the OR for the night and two different periods during the day.
