Every year, in Germany alone, around 7000 people wait for a new cornea to save their eyesight. But donor corneas are in short supply. In an EU project, researchers have developed an artificial cornea which is to be clinically tested in early 2008.

A patient whose cornea is damaged through a congenital malformation, hereditary disease or corrosion is at risk of going blind. One solution is to implant a donor cornea. The central part of the natural cornea is removed in a circular fashion, and the new cornea is inserted and sutured in place. A vast number of patients are affected: every year, 40,000 people in Europe alone hope for a donor – often in vain.

- Global Advocacy Groups Launch Joint Effort to Preserve Eyesight of Millions At-Risk for Glaucoma

Results of a new international survey reveal that eye exams are being ignored by many aged over 40. Only two fifths of respondents had visited an eye specialist in the last year to have their eyes checked, even though twice as many people feared going blind compared to heart disease or early death. The survey showed that awareness of glaucoma was extremely low. A total of 40 percent of people surveyed were unaware that glaucoma is linked to blindness, even though it is the second leading cause of blindness. World wide, approximately 6.7 million people are blind from glaucoma, with almost 70 million affected by the disease.(1),(2)

Researchers have discovered that even the gruesome and brutal lifestyle of the Evarcha culicivora, a blood gorging jumping spider indigenous to East Africa, can’t help but be tempted by that ‘big is beautiful’ mantra no matter what the costs.

A study recently published in Ethology found that despite the inherent risk of sexual cannibalism, virgin females were attracted to bigger males when losing their virginity before opting for the safer smaller male as a longer term mate choice.


Pick me, pick me. I am too small to eat you.

Planning for a summer delivery for your child? You might want to choose an ophthalmologist along with an obstetrician.

If your child is born in the winter or fall, it will have better long-range eyesight throughout its lifetime and less chance of requiring thick corrective glasses, predicts a Tel Aviv University investigation led by Dr. Yossi Mandel, a senior ophthalmologist in the Israel Defense Forces Medical Corps.

Forming a large multi-center Israeli team, the scientists took data on Israeli youth aged 16-23 and retroactively correlated the incidence of myopia (short-sightedness) with their month of birth. The results were astonishing.

People suffering from a severe retinal disease will sooner or later lose their eyesight considerably or even become completely blind.

Coordinated by the geneticist Ronald Roepman from Nijemegen, an international team has identified a further gene for the inherited retinal disease Leber Congenital Amaurosis (LCA) and discovered evidence how it functions. This represents new opportunities for gene therapy, a very promising approach for LCA since the disease is caused by a single mutation.

LCA causes blindness very early on – often shortly after or within a few months of birth. The disease can be caused through a single mutation in different genes; with the newly discovered LCA5 gene, ten disease-causing genes had been identified so far which are responsible for approx.

Tears protect and lubricate the cornea and conjunctiva of the eye and help provide a clear medium through which we see. When human tears break up too quickly, eyes feel gritty, hot and scratchy -- even eyesight can become blurry. For many people the solution has been to use artificial tears, but they're expensive and they don't last as long the real thing.

Associate Professor Millar, from the School of Natural Sciences, says the interaction between the liquid tear and air holds the key to slowing the 'break-up time' of tears.

Michael Marmor, MD, wanted to know what it was like to see through the eyes of an artist. Literally.

After writing two books on the topic of artists and eye disease, the Stanford University School of Medicine ophthalmologist decided to go one step further and create images that would show how artists with eye disease actually saw their world and their canvases.

I saw a press release about a global warming 'virtual march'( we'll get back to that ) and a tour being conducted by Laurie David ( married to "Seinfeld" co-creator Larry David and thus an expert on climate science, also founder of the website that put out the press release ) and Sheryl Crow called the "Stop Global Warming College Tour" beginning April 9th in Dallas.

I was itching to find more information about it and, other than discovering they were going to show clips from Al Gore's movie ( yeah, no college student will have seen that ) and Sheryl Crow would sing a few songs at each stop, the only interesting thing I came across was an article in something called the
