Jan. 28, 2010— -- When Taylor Garrison gave birth in October, she was astonished that doctors whisked her girl, Brielle, out of the delivery room without much caption.
"They took her out of the room, and they wouldn't permit united states run across her," said Garrison, 15, of Wellington, Fla.
Finally, after vi hours of tests, Garrison got to await briefly at her baby and meet what doctors were so concerned about.
"She looked similar a normal baby, but I could only tell something was incorrect," Garrison said.
Brielle was built-in without whatever eye tissue at all, a condition called anophthalmia that leaves a person irrevocably blind.
Garrison likewise learned this rare diagnosis was one that is almost always missed past ultrasound -- even though hundreds of genetic diseases and deformities one time discovered at nativity can at present exist detected with the latest ultrasound engineering science.
How Ultrasound Could Miss Brielle'due south Condition
"If you wait at the ultrasounds, where the eye sockets are they're just blackness because the eyes are fabricated of h2o," Garrison said. Just Brielle'due south center sockets were just empty.
Dr. Aaron Fay, manager of Ophthalmic Plastic Surgery at the Massachusetts Eye and Ear Infirmary, is currently treating 10 patients with the rare disorder.
The status of either partially (microphthalmia) or completely missing eye tissue occurs in thirty in 100,000 births, and although in concept, Fay said, doctors could mayhap encounter the missing eyes in utero with an MRI, it is rarely diagnosed in the womb.
"There are skeletal stigmata that could be picked up," Fay said. "But it's near frequently diagnosed at birth."
The condition is not inherited, Fay said, so families have no clue that their child may be carrying the deformity. It could be a genetic mutation, or an unexplained occurrence in the first few weeks of pregnancy.
Garrison said Brielle's genetic screening came upward clear.
"She got a chromosome test, and she came back as a normal babe girl," Garrison said.
However, eye and genetic screening specialists say a genetic mutation tin can sometimes atomic number 82 to anophthalmia.
How Doctors Could Possibly Know nearly Anophthalmia
"A number of those patients have a problem on chromosome 13," said Michael S. Watson, executive director of the American College of Medical Genetics.
If a doctor somehow suspects a problem with the eyes, which happened to babe Faith featured by ABCNews.com in Nov, then Watson said mothers could go in for prenatal genetic screening.
"We certainly can exam for, with great accurateness, for chromosome abnormalities and that has been the case for forty years," said Dr. Mark Evans, a member of the American Congress of Obstetricians and Gynecologists.
"At that place are hundreds of them, however the vast majority occur with chromosome 21, 13 and xviii," said Evans, of Comprehensive Genetics in New York City.
With such quondam technology and more genes discovered every day, one might wonder why every woman wouldn't go prenatal genetic screening.
"Simply we do not routinely test everybody for everything considering nosotros'd bankrupt the land," Evans said.
Evans also thought that occasionally a false security in ultrasounds keeps prenatal genetic screening rates low, in addition to the high costs.
"What has happened in the final 20 years is that many women are being falsely reassured past ultrasound and not going on to genetic testing," Evans said. "In some places the birth rates of these (genetic) problems have gone upwardly."
Equally ultrasounds for women seeking prenatal care have become almost universal in the United States and, as Evans argued, maybe overly reassuring, doctors also say that the prenatal imaging has evolved into high tech and low tech uses.
Now, a portion of obstetricians accept become experts in using prenatal imaging to diagnose genetic disorders an ultrasound wouldn't have caught a generation ago.
"What you can see in prenatal imaging is changing enormously," Watson said. "Y'all stop upwards with 2 different kinds of people who do imaging. One level is the standard obstetrician on the corner, who can practice the basic measurements and tell you lot if your infant is growing unremarkably and you end up with a picture on your refrigerator."
Non Every Obstetrician is An Adept in Prenatal Imaging
The other, Watson said, are people who specialize in loftier-risk pregnancies and can use ultrasounds to diagnose, or even treat more and more genetic abnormalities.
"At the commencement level it'due south a matter of someone being suspicious that something is going on," Watson said. "The patient can and so go to an obstetrician who specializes in high hazard pregnancies."
Doctors can even care for a few of the nativity defects in the womb -- such equally Spina bifida or twin to twin transfusion syndrome -- if ultrasounds selection upwardly on the disorder, Watson said.
Using Ultrasound to Discover Red Flags for Genetic Disorders
Evans said ultrasounds today tin can even heighten reddish flags for Downward syndrome, although the status is not treated in the womb, and warning a adult female that she might demand genetic screening.
"There are certain markers on ultrasound that change the odds (of a genetic disorder), for example the nuchal translucency, which is thickness of the back of the neck in the get-go trimester, can be a marking for Down syndrome," said Evans.
Garrison said she chose to become to the public with her story because, her family had never heard about Brielle's disorder, dissimilar Down syndrome or other more than well known conditions.
"Information technology'due south just and so rare, about people don't know that it really exists," said Garrison "If more people know about it, then information technology'southward more likely people volition study it."
For the next few years, Brielle will accept to see doctors for conformers -- balls filled with hydrogels to increase the size of her middle sockets -- in lodge for her facial construction to grow usually.
Fay says he and his colleagues at Massachusetts Eye and Ear are continually looking for new ways to aid children with the status grow as unremarkably equally possible before they receive prosthetic eyes.
Since speaking with ABC News chapter WPBF in Due west Palm Beach, Fla., Garrison said parents of children with anophthalmia or microphthalmia have contacted her seeking support.
"A lot of worse things could have happened and thank god they didn't," Garrison said. "I see her just as any other baby. She does everything any other babe would."
