care for the newborn : THE EYES IN THE NEWBORN
The eyes of the newborn consist of the same structures as that of the adult. However, they have a long way to go before becoming a full-fledged visual system.
The outer shell of the eye — exposed — consists of two unequal parts: the opaque white sclera and the transparent cornea is convex. Sclera baby thin, bluish. The cornea is transparent and shiny, in the first days of life sometimes seems dull.
Behind the cornea lies the iris, which determines eye color. Most newborns it a blue-gray. In the center of the iris is the pupil — the opening through which light enters the photoreceptors. The pupils of newborns are narrow, poorly reactive to light.
Conjunctiva — connective sheath that covers the posterior surface of the eyelids and anterior surface of sclera up to the cornea. Conjunctiva the kids are fine, no visible vascular pattern.
The eyes of the newborn is not fully open, as the muscles age is still poorly developed. For this reason, during sleep the eyes are often half open. Kids rarely blinking for 2-3 times per minute (adult — 8-12).
The lacrimal gland begins to actively work in 1-1. 5 months, so before this time a crying infant "is" without tears.
Since the visual system begins to develop only after birth, at first she lags behind the other senses. However, after a few weeks the situation changes.
Immediately after birth the baby reacts to light, briefly turning her head in his direction and tries to follow the moving subject. But in 2-5 weeks the baby stares at the light source. By the end of the first month, he briefly fixes his eyes on an object closer to three months, begins to actively react to mother's breast or bottle milk, 4 month old tries to grab the toy, and in 4-5 months will close.
Conjunctivitis is an inflammation of the conjunctiva caused by bacteria. The child cannot look at light, his eyes are watering, there may be purulent discharge.
Dacryocystitis is an inflammation of the lacrimal SAC. Externally, the disease is similar to conjunctivitis. Treatment antibiotic drops and massage of the lacrimal SAC, but with no effect — by probing and irrigating lacrimal ducts.
Strabismus — up to 4 months the baby can be observed physiological squint. If you notice that the older child squints with only one eye, and in a certain direction, see an ophthalmologist.
