credited with restoring vision for many with macular degeneration.

Lying
on his back with an "X" drawn above his left brow
and his eyelids held back, 69-year-old Ernie Davis looks up
and to the right as his doctor uses a cotton swab and drops
to clean and numb the white part of his left eye.
" A
little pinch," Dr. Andy Kimmel says as he inserts a needle
into Davis' eyeball and injects a few drops of a solution called
Lucentis.
The retired accountant from Hellertown doesn't flinch. This is his seventh injection at St. Luke's Hospital-Fountain Hill. And as horrifying as having a needle stuck in your eye may sound, it's been worth it.
Davis
has macular degeneration, a progressive disease that is the
leading cause of blindness. After only two injections of Lucentis,
he could see letters on an eye chart that before looked like
a gray blur.
Lucentis,
approved by the U.S. Food and Drug Administration in June for
patients with the so-called "wet" form of macular degeneration, is being hailed by doctors here and across the country as a major breakthrough in treating blindness.
Some
10 million people suffer from macular degeneration; about 2
million of them have the "wet" form that Lucentis can help. And as more baby boomers move into their senior years, millions more will begin losing their eyesight to the disease. But until now, there's been no known cure and treatment options left patients less than satisfied.
Not
only can Lucentis prevent the progression of the disease, it
can restore vision. Results from two studies published in October
in the New England Journal of Medicine showed that among more
than 700 patients treated over two years, Lucentis stopped
vision loss in 95 percent of patients and improved vision in
one-third.
Dr.
Maz Kazahaya, chief of ophthalmology at Lehigh Valley Hospital
It might not work on patients with the most advanced form of
the disease,
those who've had it for 10 years or more.
And
the drug is not without side effects, including serious infections,
cataracts and retina detachments.
Still,
Kazahaya said, any eye specialist not offering Lucentis "is doing patients a disservice."
Macular
degeneration is a condition in which the macula, or center-most
part of the retina, deteriorates. The retina is the movie-screen-like
surface at the back of the eye upon which images are projected.
Heredity,
smoking, obesity and high blood pressure are believed to contribute
to the condition.
Early
symptoms include distorted vision, in which a straight line
looks wavy, and a dark blotch at the center of vision. If the
condition
progresses and tiny new blood vessels grow into the retinal
wall and bleed, it is considered "wet" macular degeneration.
Not
everyone who has "dry" macular degeneration will get the "wet" form, experts say, but those who do generally see it happen around age 70.
Lucentis
works by killing off the new blood vessels growing and bleeding
into the retina. It is made by Genentech, a biotechnology company
in South San Francisco, Calif.
Before
Lucentis, patients with macular degeneration underwent photodynamic
therapy, a laser treatment to seal leaky blood vessels, or
they were
given the drug Macugen, said Dr. George A. Williams, a retina
specialist in Royal Oak, Mich., and spokesman for the American
Academy of Ophthalmology. They slowed the disease and prevented
severe vision loss in most patients.
"But still, many felt their vision was quite poor," Williams said.
Another
option was Avastin, a cancer drug also made by Genentech If
Avastin proves just as effective, it would mean a huge savings.
Avastin costs $50 a dose, compared with Lucentis' $1,950 price
tag.
Health
care plans cover Lucentis. For those whose plans don't or who
can't afford co-payments to doctors and hospitals, Genentech
provides the
drug free or refers patients to some charities known to help.
Kimmel
started giving the injections in August and already has more
than 70 patients on the drug. He injects one eye per visit
at St. Luke's retina
center in Fountain Hill, then schedules a follow-up visit
in his office the next day. For patients with the disease
in both
eyes, that means twice as many visits.
On
a recent Monday morning, he gave injections to a dozen patients
at the St. Luke's retina center before starting office hours
across
the street.
Kazahaya
said he gives injections to about five patients each day.
"So many patients have wet macular degeneration," he said. Genentech recommends that patients receive one injection a month in each eye with the disease for a year, with monitoring to continue beyond that. For patients, the biggest barrier is not the newness of the drug or the price tag. It's the way it's administered.
"Just the thought of getting an injection in the eye is psychologically hard to grasp," Kazahaya acknowledges. "But once they have it done, they say it wasn't so bad.
"The second [shot] becomes easier and after the third or more, when they've seen improvement in vision, they want it."
A
number of Kimmel's patients agree.
"I'll take anything as long as I can see," said Chester Feidler, 78, of South Whitehall Township.
When
diagnosed in September, Feidler said he could not see well
enough to distinguish what was on his dinner plate. "I was embarrassed if I got prime rib because I couldn't tell where the fat was," he said.
But
after the second shot in his right eye earlier this month,
Feidler was no longer "legally blind" in that eye and could clearly see his food.
"I was tickled," he said.
Pat Brown, a 69-year-old semiretired high school "lunch lady" from Phillipsburg, said she was "scared to death" of getting a needle in the eye. Now that she's had three, she's no longer afraid.
"It does not hurt," she said. "Unbelievable."
Although
Brown didn't feel pain, she did see specks, sometimes called "floaters," from the injected solution immediately after the shot, like many other patients.
Brown
likened the effect to looking through a kaleidoscope. The squiggly
shapes and colors typically last a few hours or till the next
day.
The
desired effect of better vision occurred after the second injection
in her right eye, she said. The fuzzy black spot blurring the
center
of her vision had disappeared.
"Dr. Kimmel has given me some of my sight back," Brown said.
Davis, who has had the disease for five years, said two injections were all it took to improve his vision by two lines on the eye chart.
The improvement is to his "good" eye, not the "bad" one, but
Davis
is thrilled nonetheless.
"My wife and I are extremely happy with these results," he said. The injections "are saving my vision from getting any worse."
As
they treat more patients with Lucentis, doctors are still trying
to determine which patients will respond best.
Williams,
who works at the William Beaumont Hospital in Royal Oak, said
he's treated more than 100 patients since the beginning of
July. "The drug works best early in the disease," he said. "I tell patients that if they have had poor vision for a long time, maybe 10 years or more, it is unlikely this will be a big benefit to you."
Fairly
often, he turns such patients away.
"Lucentis is not for everybody," Kazahaya said. "It's only for those with active disease. It there's scarring already, Lucentis won't reverse that." Research trials didn't include such patients, he said.
But
because Lucentis hasn't been tested on many advanced-stage
cases and patients react differently, Kimmel said he doesn't
want to turn someone away who might benefit.
"The really bad cases, who have had macular degeneration a long time, I wish I had had earlier," he said. "But I am willing to offer it. No one has the data to show if it's efficacious or not."
Kimmel
said he's seen Lucentis work on patients, such as Madeline
Walsh of Bethlehem, who have had the disease for four to five
years.
Walsh
said at a recent visit at St. Luke's that she could see the
numbers on her alarm clock after her second injection.
"The only problem with that," a nurse quipped, "is now you have to get out of bed."
SEEING
SUCCESS

show Lucentis stopped vision loss in 95 percent of patients
and improved vision in one-third.
