How to Take Care of Your Eyes as You Age: be aware of GMC: Glaucoma, Macular degeneration, Cataract

FromConsumer Reports:GlaucomaMore than 2 million Americans have glaucoma, but 50% know it. Glaucoma often goes undiagnosed because it causes no symptoms until vision declines, at which point treatment no longer helps.People aged 40-60 should be examined by an optometrist every 3-5 years; those older than 60 need an eye exam every 1-2 years.Many eye doctors screen for glaucoma with tonometry (measures eye pressure) but that ’s not enough. Relying only on intraocular pressure (IOP) when screening for glaucoma could miss up to 50% of all cases. Theexam should also include an ophthalmoscopy, which involves examining your optic nerve.The most common treatment for glaucoma is eye drops known asprostaglandin analogs (PGAs),which lower eye pressure. Generic versions of most of those drugs are much cheaper than the brand-name versions.Age-related Macular Degeneration (AMD)There are two main forms of AMD:1.Dry AMD, more common variety, which is treated mainly with dietary supplementsA specific blend of vitamins and minerals known as AREDS (vitamins C and E, plus copper, lutein, zeaxanthin, and zinc) lowers the risk of dry AMD progression by 25%. It ’s the only treatment as of 2019.Not all eye supplements contain the proper formulation. In an analysis of 11 eye-health supplements, only 4 contained the right mix: PreserVision Eye Vitamin AREDS Formula, PreserVision Eye Vitamin Lutein Formula, PreserVision AREDS2 Formula, and ICAPS AREDS.Don ’t bother taking an...

Authors: Mascitti M, Togni L, Rubini C, Troiano G, Lo Muzio L, Santarelli A Abstract Oral squamous cell carcinoma is the most common head and neck malignancy, characterised by high invasive capacity, lymph node metastasis, and high recurrence rate. Among the morphological features of oral cancer, the tumour-associated tissue eosinophilia has gained growing interest in the last years. Eosinophils are a minor subpopulation of leukocytes, representing 1-3% of all circulating white blood cells. The presence of high levels of eosinophils is associated with several diseases, but their role in cancer pathophysiology is co...

In conclusion, elevated brain amyloid was associated with family history and APOE ε4 allele but not with multiple other previously reported risk factors for AD. Elevated amyloid was associated with lower test performance results and increased reports of subtle recent declines in daily cognitive function. These results support the hypothesis that elevated amyloid represents an early stage in the Alzheimer's continuum.

Cellular senescence contributes to many age-related diseases. Senescent cells arise naturally as a result of the Hayflick limit on cellular replication, as well as injury, or due to molecular damage or a toxic environment that might give rise to cancer. A senescent cell ceases replication and secretes a potent mix of signals that produce inflammation and disrupt nearby tissue structure and function. In youth, senescent cells are near all quickly removed, via programmed cell death or the actions of the immune system, but these removal mechanisms falter with age. Senescent cells accumulate as a result, and the more of them t...

They are an oxidized version of carotenoid. Xanthophyll has widely drawn scientists' attentions in terms of its functionality, bioavailability and diversity. An assortment of xanthophyll varieties includes lutein, zeaxanthin, β-cryptoxanthin, capsanthin, astaxanthin, and fucoxan...

It’s no secret that air pollution isn’t good for your health. In particular, exposure to the byproducts of burning the fuel that powers most of our motor vehicles has been linked to higher risk of lung cancer, respiratory infections, stroke and heart disease, as well as an increased risk of death from these conditions. A new study now adds another worrisome pollution-related risk: eye disease. Dr. Suh-Hang Hank Juo, from the center for myopia and eye disease at China Medical University in Taiwan, and his colleagues documented for the first time in a large population that exposure to two common air pollutants&md...

Abstract Extensive research during the past three decades has demonstrated the mechanisms by which an imbalance in the redox status of prooxidant/antioxidant reactions in cells with advantage of prooxidant reactions (oxidative stress, OS) can cause peroxidation of nucleic acids, bases, lipids, proteins and carbohydrates, thus resulting in their damage. These actions result in stimulation of signal transduction pathways and activation of transcription factors that can lead to chronic inflammation and cause tissue dysfunction. The most important oxidants are reactive oxygen species (ROS) and reactive nitrogen specie...

When kids pack for summer camp, sunglasses may not always top the supply list. But I made them a priority for my 12-year-old son Carson, who just started rowing camp in Florida, for two reasons: Our eyes are most vulnerable to the sun’s ultraviolet rays in our teens, 20s, and 30s, although the damage usually doesn’t show up until later in life. The sun’s rays are especially intense near reflective surfaces. “If you spend time near the water, the beach, or snow, the sunlight bounces off of those surfaces and right into the eyes,” Dr. Louis Pasquale told me. He’s an ophthalmologist at Ha...
