Watermelon is a great summer fruit, but it also has some powerful health benefits that you may not know about. The key nutrient in this tasty melon is lycopene, a carotenoid found in red fruits and vegetables, which is essential for eye health. Research has shown that a deficiency in lycopene is associated with macular degeneration. As such, it is important to maintain a diet rich in lycopene and other nutrients essential to preventing disease.
You’ve probably seen lycopene touted on bottles of tomato ketchup. It’s true that tomatoes are one source of lycopene, but ketchup Continue reading
In the case of choroidal neovascularization (CNV, also known as “wet” macular degeneration), new blood vessels are the cause of the problem. Yet normally when new blood vessels are created in the body, it is a good sign. For example, it is part of the way the body heals wounds. But with CNV, the blood vessels pose a problem because they originate in the choroid layer of the eye and pass through a weak part of the Bruch’s membrane, the innermost layer of choroid, then pass into the subretinal pigment epithelium (sub-RPE) or subretinal space. These blood vessels aren’t supposed to exist in this part of the eye, are weak and tend to leak, potentially substantially impairing vision.
Oxygen and nutrients are provided to the eye by the choroid. The choroid Continue reading
Excessive time spent in front of a computer, smartphone, or tablet screen can increase risk of macular degeneration, especially in young people.
The AOA’s survey focused on how much time parents thought their children spent on handheld devices. Their responses easily underestimated those of the children, aged 10 to 17, who reported (83%) that they use a handheld device for at least three hours a day, with 32 percent looking at a screen for more than an hour without glancing Continue reading
Research suggests that individuals with retinitis pigmentosa (RP) may benefit from a dietary iodine supplement. RP patients often experience retinal swelling as a result of Cystoid Macular Edema (CME). A study published in JAMA Ophthalmology showed swelling due to CME to be inversely related to iodine intake.
The study was conducted by researchers from Massachusetts Eye and Ear, Harvard Medical School, and Boston University School of Medicine. Using a Continue reading
Research on turmeric spice indicates its potential to fight depression, cancer, diabetes, and neurodegenerative disease. The bright yellow spice, which lends color and flavor to mustard, curry, and other foods, also contains highly beneficial chemicals like curcumin.
Curcumin has been studied widely in the past, but it only makes up about two to five percent of the turmeric spice. Researchers from the Cytokine Research Laboratory Continue reading
Central Serous Choroidopathy, also known as Central Serous Retinopathy (CSR) and Central Serous Chorioretinopathy (CSC), is an eye condition which causes visual impairment. It usually occurs in one eye, and it is usually temporary. But studies show that both eyes are affected on a cellular level even when damage is only apparent in one eye.
CSC is characterized by fluid leakage beneath the retina. Fluid leaks from the layer of the eye called the choroid. This is a heavily vascularized membrane that nourishes the Continue reading
How can you prevent and reverse serious eye disease using stem cells? A new book by Damon P Miller II MD, Carlyle Coash MA, and Adam Miller examines the potential for stem cells to address macular degeneration, retinitis pigmentosa, Stargardt’s disease and other retinopathies. This up-and-coming area of medicine looks at research in Epigenetics and adult stem cells, and how they could help eye functioning. Learn more and buy the paperback or Kindle edition of Stem Cells Heal Your Eyes: Prevent and Help: Macular Degeneration, Retinitis Pigmentosa, Stargardt, Retinal Distrophy, and Retinopathy on Amazon.com.
Early trials of two types of eye tests show promising results in identifying Alzheimer’s Disease in its early stages. Research showed that a key protein can be detected in the retina and lens of the eye through simple tests. Both types of eye tests accurately distinguished healthy patients from those with early stages of Alzheimer’s, which was confirmed by PET (positron-emission tomography) scans.
In one trial, Australian researchers asked 200 participants to take a supplement of curcumin, an ingredient of turmeric spice. Continue reading
A new clinical trial showed positive results for patients with wet age-related macular degeneration (AMD). The study, which monitored the use and performance of Squalamine eye drops, showed improvement in a number of visual functions.
Conducted by Ohr Pharmaceutical, the nine-month research was a Phase II clinical trial that tested for the effectiveness of Squalamine eye drops in improving visual function. All patients had administered eye drops two times per day, either Squalamine or a placebo, plus injections of Continue reading
Diabetic retinopathy is an eye disease that is a complication of diabetes. In diabetes, levels of blood sugar are chronically elevated due to lack of insulin, an insulin insensitivity, or a combination of both. Just as sugar combined with water outside the body forms a sticky substance, excessive sugar in the bloodstream does so as well. Sugar adheres to numerous different tissues in the body, causing problems depending on the tissue. Prolonged excessive sugar in the bloodstream tends to damage the blood vessels of the retina, the back part of the eye that sends light signals to the brain. As the blood vessels Continue reading
