Macular Degeneration And A Healthy Lifestyle

We now have another condition that may be prevented by eating a healthy diet, exercising, and abstaining from smoking: Age-related macular degeneration (AMD).

Macular degeneration causes a loss of central vision and makes it difficult to recognize faces and read small print. The macula degenerates with age and severe macular degeneration causes blindness. Treatment is costly and doesn’t work very well.

A new study published in the Archives of Ophthalmology looked at 1,313 women aged 55 to 74 years. They reviewed their diet and exercise habits. Eating a “healthy diet” meant 3.5 servings of fruit and vegetables, 2.3 servings of dairy, 2.7 ounces of meet and 3.5 servings of grain a day. Exercise habits and smoking history were also monitored.

A “Touch” Of Outer Space For The Blind

NASA, in an attempt to have visually-impaired people get a glimpse of what’s “out there,” has created a reconstruction of a Hubble image of the Carina Nebula in a 3D touch map.

Different textures applied to the image help in identifying the various parts of the giant dust cloud. We even think that visually-okay folks can get a better sense of the cosmic anatomy when offered such a presentation.

Vitamin E-Infused Contact Lenses May Treat Glaucoma

44543444.jpgResearchers at the University of Florida in Gainesville have developed a vitamin E-secreting contact lens that can bring the valuable antioxidant directly to eyes.

Vitamin E is packaged into clusters within the lens and the aggregate works to slowly release the chemical while remaining invisible to the eye.

“These vitamin structures are like ‘nanobricks’,” said Anuj Chauhan, Ph.D., lead researcher of the study. “The drug molecules can’t go through the vitamin E. They must go around it. Because the nanobricks are so much bigger than the drug molecules -– we believe about a few hundred times bigger –- the molecules get diverted and must travel a longer path. This increases the duration of the drug release from the lenses.” Read more »

The Spirit Of The Place: Samuel Shem’s New Book May Depress You

When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…

Eat To Save Your Life: Another Half-True Diet Book

I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
