Hermann von Helmholtz) to later operate on his own mother's eye.
Greece Blinks on Euro Threat
Greece's leaders worked to restore political stability in the country and preserve its euro membership, killing a plan for a referendum on Greece's latest bailout that has roiled global markets and infuriated European leaders.
Last month, the administration
announced a $6 billion arms sales package to Taiwan, infuriating Chinese officials.
The government is preparing legislation to allow companies hit by the global economic crisis to apply for public funds, but any capital injection could infuriate other chipmakers and crush prospects of a recovery in chip prices this year.
Genentech had infuriated many eye doctors in October when it announced a change in the distribution of Avastin that would have made it difficult for eye doctors to use the drug. The doctors had accused the company of trying to force them to use a much more expensive drug, Lucentis.
Lucentis is approved to treat
macular degeneration, a leading cause of
blindness among the elderly, but it costs about $2,000 for each injection, and is needed as often as once a month.

Macula 斑點
From Wikipedia, the free encyclopedia
The
macula or
macula lutea (from
Latin macula, "spot" +
lutea, "yellow") is an oval
yellow spot near the center of the
retina of the human
eye. It has a diameter of about 1.5 mm and is often histologically defined as having two or more layers of
ganglion cells. Near its center is the
fovea, a small pit that contains the largest concentration of
cone cells in the eye and is responsible for central vision.
It is specialized for high
acuity vision. Within the macula are the fovea and foveola which contain a high density of
cones (photoreceptors with high acuity).
[edit] Clinical significance
Whereas loss of
peripheral vision may go unnoticed for some time, damage to the macula will result in loss of central vision, which is usually immediately obvious. The progressive destruction of the macula is a
disease known as
macular degeneration and leads to the creation of a macular hole. Macular holes can rarely be caused by trauma, but if a severe blow is delivered perfectly it can burst the blood vessels going to the macula, destroying it.
Visual input to the macula occupies a substantial portion of the brain's visual capacity. As a result, some forms of
visual field loss can occur without involving the macula; this is termed
macular sparing. (For example,
visual field testing might demonstrate
homonymous hemianopsia with macular sparing.) This finding can be very informative for the
ophthalmologist.
