Sleep Apnea - Symptoms and TypesWritten by Tony McGlinn
Continued from page 1
The most common type of sleep apnea is obstructive sleep apnea, usually referred to as OSA. It happens because throat closes completely during sleep. This happens because suction forces that come from snoring cause persons tongue and soft palate, to be sucked into airway and block it. When person wakes up, muscles in throat and tongue contract and person starts to breathe again. Another type of sleep apnea is central apnea. This happens when brain and nervous system are not co-ordinated in telling body when to breathe. Mixed apnea includes elements of both obstructive and central apnea.

Amblyopia – Also known as lazy eye, occurs when vision in one eye is reduced. The brain favors stronger eye and uses it to process visual information Retinopathy of Prematurity – Retinopathy of prematurity is caused from exposure of premature infants to excessive oxygen. The excessive oxygen can cause abnormal blood vessels grow and spread throughout retina in a premature infant. These blood vessels can leak and cause damage to retina. Albinism – Albinism involves a lack of pigment in hair, skin and eyes. The lack of pigment affects functioning of retina and causes vision to be impaired. Cataracts – A cataract is an opacity or cloudiness of lens. If lens is cloudy it will obstruct passage of light to back of eye causing vision to be impaired. Cortical Visual Impairment – Cortical vision impairment is caused when portion of brain that processes visual information is missing or damaged. Strabismus – Strabismus, also known as crossed eyes or wandering eyes, occurs when eyes do not work together properly and appear misaligned. Microphthalmia, Anophthalmia, and Coloboma - Micropthalmia occurs when eyes are abnormally small, anopthalmia is when eyes are missing and coloboma means that there is a gap in one of structures of eye.
