Summary
Age-related maculopathy (ARM), a leading cause of elderly blindness, is linked to age, smoking, and family history. Genetic factors and gene-environment interactions also play a role in its development.
Area of Science:
- Ophthalmology
- Epidemiology
- Genetics
Background:
- Age-related maculopathy (ARM) is a primary cause of vision loss in older adults.
- Current understanding of ARM's causes is incomplete, hindering effective treatment development.
- Conflicting data from epidemiological studies complicates definitive conclusions on risk factors.
Purpose of the Study:
- To synthesize and review existing literature on risk factors for age-related maculopathy.
- To consolidate findings from various epidemiological study designs.
Main Methods:
- Systematic literature review of published cross-sectional, prospective cohort, case series, and case-control studies.
- Appraisal of studies investigating risk factors for age-related maculopathy.
Main Results:
- Consistent risk factors identified across studies include advanced age, cigarette smoking, and a family history of ARM.
- Genetic studies have implicated specific genes (e.g., Complement Factor H, PLEKHA1, LOC387715/HTRA1) in ARM pathogenesis.
- Evidence suggests both environmental and genetic factors contribute significantly to ARM development.
Conclusions:
- Age, smoking, and family history are established risk factors for age-related maculopathy.
- Gene-environment interactions are crucial in the pathogenesis of ARM.
- Further research into genetic and environmental influences is warranted for therapeutic advancements.

01:27Diabetic Retinopathy
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
01:29Alzheimer Disease l: Introduction
Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...
01:27Pharmacodynamics in Geriatric Patients: Effects of Age
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
01:19The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
