Myopic macular degeneration is not commonly known in the U.S. even though it is the 7th highest ranking cause of legal blindness. In other parts of the world, such as Japan and China, it is the second highest cause of legal blindness. In addition, people of Jewish and middle eastern extraction are greater risk of developing the condition.
What is It?
Myopic macular degeneration (MMD) arises primarily from genetic abnormalities. 30% of all cases were present at birth; 60% of all cases develop before the child is 13. It often continues to worsen, becoming quite severe myopia by the late teens or early 20s and by 60, 50% of MMD patients are legally blind.
The condition is caused Continue reading “Myopic Macular Degeneration”
Electronics have become primary obsessions in our personal and work lives. This has lead to nearly everyone becoming susceptible to Computer Vision Syndrome. Symptoms include dry eyes, eye strain, blurred vision, headaches, double vision, difficulty in concentrating, fatigue and/or and head, neck and shoulder pain.
Clinical trials are underway for an implantable device that delivers medication directly to the eyes of people with 
A new study has found that higher levels of mercury in the blood are linked to a greater chance of developing the eye disease glaucoma. Additionally, low levels of manganese (a chemical element) were associated with lower incidence of glaucoma.
Past studies looking for an association between glaucoma and Alzheimer’s disease have been inconclusive. However, a recent 2015 large study of 7770 Alzheimer’s patients found such an association, specifically with women.
Age-related macular degeneration (AMD) has been linked to supplementing more than 800 mg of calcium per day. The link was strongest in the elderly, who suffer from AMD the most. The research was a cross-sectional study of National Health and Nutrition Examination Survey (NHANES) data. The RDA for calcium (CA) for adults is 1,000 mg; 1200 mg for women over 50. However, changes to the recommended total daily intake of CA have not been suggested.
Medical marijuana, or cannabis, is being legalized in more and more American states. For more than 40 years, the effect of medical marijuana on glaucoma has been studied. As cannabis becomes more accessible — and legal — glaucoma patients are becoming more interested in how this drug could help with their condition.
Several different types of glaucoma are the leading cause of blindness in the US[1. https://www.glaucoma.org/glaucoma/glaucoma-facts-and-stats.php Glaucoma Research Foundation], and yet many cases of glaucoma begin without symptoms. Half of the 3 million-plus Americans who have glaucoma have been diagnosed.[2. The Eye Diseases Prevalence Research Group, Archives of Ophthalmology, 2004; Prevent Blindness America] Glaucoma can affect anyone, but it is especially prevalent in persons over age 60. Everyone should have regular eye exams throughout their lives to screen for glaucoma, especially a dilated eye exam. Glaucoma tends to run in families, but anyone can get it.
A biodegradable contact lens is being developed that would administer glaucoma medication and then disappear. The problem with eye drops is that they slip out of the eye and much of the medication is lost. This contact lens, designed by Mridula P. Menon in India, uses a nano-carrier loaded with the glaucoma drug acetazolamide that is dissolved in a transparent vinyl polymer.
New 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.
