Edwards syndrome is a chromosomal abnormality characterized by the presence of an extra copy of genetic material on the 18th chromosome, either in whole (trisomy 18) or in part (such as due to translocations).The additional chromosome usually occurs before conception.t is the second-most common autosomal trisomy, after Down syndrome, that carries to term. Edwards syndrome occurs in around one in 6,000 live births, and around 80% of those affected are female. The majority of fetuses with the syndrome die before birth. The incidence increases as the mother's age increases.
Dilating drops make the pupils of the eyes bigger so that the doctor can see the back of the eye. Because the pupils are bigger, you are more sensitive to light until the effect wears off, and it's a good idea to have sunglasses for use after the exam. Jupiterimages/Goodshoot/Getty Images.
Drops placed on your eyes relax the iris, the colored part of your eye, which makes the pupil, the opening in the middle of the iris that admits light into the eye, widen so your doctor can more completely examine the inside of your eye. This allows your doctor see the back of your eye more clearly. This process helps your doctor detect diabetes, tumors, retinal detachment, high blood pressure, macular degeneration and a variety of other issues in their early stages. Although eye dilation makes your eyes sensitive to bright light for a few hours after an exam, itâs a worthy prevention effort. By detecting some of these issues earlier on, dilation could help save your vision and overall health.
