Retinopathy of Prematurity (ROP) causes abnormal blood vessels to grow in the retina, the layer of nerve tissue in the eye that enables us to see.
How is retinopathy of prematurity diagnosed?
Generally, the earlier a baby is born, the greater the risk of ROP. Because ROP has no signs or symptoms, the only way to detect it is through an eye examination by a pediatric ophthalmologist.
How is retinopathy of prematurity treated?
The results of your baby’s first eye exam will determine the need and frequency of follow-up examinations. ROP is usually diagnosed according to stages that describe how far the blood vessels have grown into the retina.
Some cases of ROP are mild and correct themselves, but others require surgery to prevent vision reduction or blindness. Surgery involves using a laser or other means to stop the growth of the abnormal blood vessels, the goal being to prevent the vessels from pulling on and detaching the retina.

More to Know
Earwax is produced by glands in the ear canal, which leads from the outer ear to the eardrum. Earwax helps protect the ear by trapping dust and other foreign particles that could damage the ear. Normally, earwax moves toward the opening of the ear and falls out or is washed away, but some people's ears produce too much wax. The extra wax can build up and harden in the ear canal and become difficult to remove. Earwax also can become impacted when, during ear cleaning, the wax is accidentally pushed deeper into the ear canal.
Impacted cerumen can cause earaches, temporary hearing loss, ringing in the ear (tinnitus), coughing, or a feeling that the ear is full or plugged. It also can increase the risk of an outer ear infection. Impacted cerumen should be removed by a doctor to help avoid damaging the ear. Treatment options include removing the earwax with instruments or by flushing the ear canal with special liquids.
Keep in Mind
Impacted cerumen may improve on its own, but treatment by a doctor is generally safe and effective. Hearing usually returns completely after the impacted earwax is removed. Trying to remove impacted cerumen at home with a cotton swab or by ear candling is not recommended.
