Eye Tests May Predict Early Alzheimer’s Disease

Alzheimer's diseaseEarly 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

New Study on Squalamine Eye Drops for Wet Macular Degeneration

eye-drop-amd-2A 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 Guide: When High Blood Sugar Damages the Eyes

diabetic risk to the eyesDiabetic 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

Eye Infections: A Guide to Keratitis, Pink Eye (Conjunctivitis) and More

eye infections - bacteriaEye infections are a result of invasion of any part of the eye by disease-causing microorganisms. These include certain pathogens that can invade the eyelid, the conjunctiva, the cornea and, in severe and serious cases, inner parts of the eye as well. Eye infections can affect one or both eyes. Although an eye infection can seem mild, it is important to get proper diagnosis and treatment to prevent potentially serious injury to the eye.

Types of Eye Infections

Pink Eye or Conjunctivitis – In the Western Continue reading

New Vision Training for Glaucoma

computer-based eye trainingNew research indicates a breakthrough in repairing vision for patients with glaucoma. A clinical trial published in JAMA Ophthalmology showed vision improvement from daily computer-based training. Retinal damage due to glaucoma is considered irreversible, but this research indicates vision restoration is possible. By continually activating patients’ residual vision, computer training may be able to strengthen vision.

The clinical trial, conducted by Drs. J. Gublin and B. A. Continue reading

Is There a Link Between Keratoconus and Magnesium?

Vision problemsKeratoconus is a disorder of the cornea that causes visual distortion. Changes in the cellular structures of the cornea cause it to thin and bend into a pronounced cone shape, losing its normal gentle curvature. This leads to several types of visual distortion including blurring, halos around lights, and, in some cases, rapid vision loss. The signature sign of Keratoconus is the perception of multiple ghostly images, called monocular polyopia.

The causes of Keratoconus are not yet known, but one possible link is magnesium deficiency. Numerous Continue reading

Antioxidant Omega-3 Fatty Acids May Help Wet Macular Deneration (AMD)

omega-3 fatty acidsA new study shows that omega-3 fatty acids could help with wet macular degeneration. Macular degeneration is expected to increase by 50% in older adults in industrialized countries by 2020. As the leading cause of vision loss in the elderly, it is a condition of serious significance. The macula is the central part of the retina. While it makes up only about 2% of the total retina, the brain devotes half of its visual processing network to information from the macula. It is responsible for central vision. The retina is a thin layer of nerves Continue reading

Seniors Are at Higher Risk for Vitreous Tears and Detachment

eye examVitreous detachment is typically seen in elderly individuals. The retina receives light signals and transmits them to the optic nerve which is connected to the back part of the brain, where light signals are interpreted and images are formed by the brain. The vitreous is composed of about 99% water and 1% collagen, hyaluronic acid, special substances Continue reading

How Sjogren’s Syndrome Dries the Eyes and Damages Health

dry eye dropsSjogren’s syndrome is an autoimmune disorder of the rheumatoid type. Rheumatoid type diseases are characterized by inflammation and pain, dry eyes and a dry mouth. There are two types. In Primary Sjogren’s syndrome, the disorder occurs without the presence of an accompanying autoimmune disorder. In Secondary Sjogren’s syndrome, it occurs in conjunction with another autoimmune disorder.

In autoimmune disease, the body’s immune system mistakes some of its own cells as foreign invaders and attacks Continue reading
