Cognitive Trajectory Before and After Cataract Surgery: A Population-Based Approach.

J Am Geriatr Soc

Department of Anesthesia and Perioperative Care, University of California, San Francisco, San Francisco, California, USA.

Background: Cataract surgery is the most common surgical procedure performed for older US adults. Cataracts are associated with poor cognition and higher rates of dementia, but whether cataract surgery improves cognition for US older adults is not known. We examined the relationship between cataract surgery and long-term change in cognition in the Health and Retirement Study, a population-based study of older US adults linked with Medicare billing data.

Article Synopsis
  • Antidepressants, particularly Tricyclics (TCAs) and some new treatments, may increase the risk of cataracts, while others like Tetracyclics (TeCAs) and Monoamine Oxidase Inhibitors (MAOIs) appear to lower that risk.
  • Several types of antidepressants, including SSRIs and SNRIs, have been linked to an increased risk of glaucoma, with risk ratios (RORs) showing significant associations.
  • However, the study is limited by potential duplicate reports in the FDA database, and causality can't be definitively established. Overall, most antidepressants investigated were linked to lower cataract risk, but caution is needed in interpreting these findings

Increasing evidence on the adverse health impacts of microplastics (MPs) is available, but their associated risks to the well-being of humans and long-term impacts are poorly understood. An indicator of the remote effects of MPs may be their influence on the rate of aging. To assess the effects of MPs on the aging process, we used accelerated senescence OXYS rats that develop a complex of geriatric diseases.

Early exposure to Western Diet exacerbates visual outcomes in female mice.

Obesity, a growing pandemic in Western societies, significantly impacts metabolic health and contributes to visual disorders. While the systemic consequences of obesity, such as chronic inflammation and insulin resistance, are well-studied in adults, its early-life effects on retinal health remain underexplored. Using a maternal Western Diet (WD) exposure model, we investigated the developmental impact of early-life metabolic disturbances on retinal and cognitive function.

Article Synopsis
  • - The increase in life expectancy is leading to higher rates of frailty and eye diseases in the elderly, with conditions like cataracts and glaucoma being particularly impactful, resulting in visual impairment that affects daily living and mental health.
  • - Visual impairment due to eye diseases is closely linked to cognitive decline, creating a vicious cycle where reduced sensory input worsens cognitive health, leading to issues like depression and social isolation.
  • - The review emphasizes the need for early intervention and interdisciplinary care to manage eye diseases and their cognitive implications in the elderly, highlighting the critical role of ophthalmologists in these efforts.
