Explain the blindness from levels of high oxygen when given to a premature infant?

Explain the blindness from levels of high oxygen when given to a premature infant?

Environment: The environment that produces normal eyes is the womb. While in the womb, baby's eyes get about 60% blood oxygen content. Early work with premi's included putting them in "incubators" & piping in oxygen, hoping that they survived. Testing blood gasses was almost impossible, but when obtained, O2 use was geared at keeping above 90%.Now they keep it lower. The high blood oxygen triggered damage in some ...Read more

Blindness (Definition)

Vision impairment and blindness are conditions in which a person cannot see well or see at all, even with glasses or contact lenses. If a person's best vision (with correction) out of either eye is only 20/70 - 20/200, he is impaired. If he can see no better than 20/200 or his visual field is no more than 20 degrees (severe "tunnel" vision), ...Read more

The "symptom" of true blindness is lack of light perception but there are varying degrees of vision loss, some of which can be improved with treatment. ...Read more

What are symptoms of night blindness and how is it tested?

Peripheral vision: Night blindness - usually means deficiency of vision in low light situations, like finding a seat in a dark movie theater, bumping into things in the dark. There is an effect on the rods, or light and dark sensing cells in the retina. A specialized test can be done to make sure these cells are working well, it's called a (dark adapted) electro-retinogram. ...Read more

What happens when a baby is born extremely near-sighted? Are they ever mistaken for being blind?

Yes: Yes, a baby can be born extremely near sighted. I saw a girl myself who was thought to be blind and it turns out she was severely nearsighted. A proper eye exam with something called a "cycloplegic refraction" can detect it. But only once you give the glasses will you be able to tell if the child can see. Keep in mind that although possible, babies are almost exclusively far sighted at birth ...Read more

As an adult, the eyes cannot fixate, the pupils usually react to light but no vision will be reported. ...Read more

Looked at the sun for 2 seconds taking a pic with my cel. But closed my eyes right away. Can I get blind now I'm really afraid. How soon symptoms show?

Looked at the sun for 2 seconds taking a pic with my cel. But closed my eyes right away. Can I get blind now I'm really afraid. How soon symptoms show?

Unlikely: What you need is reassurance about what happened to you. You momentarily had the sun imaged on your eye but your pupillary response is fractions of a second and your avoidance of bright light is also active. So you probably never had enough sunlight at one spot on your retina to do any damage. You can check by looking at a grid graph paper with each eye and see if the grid is intact. ...Read more

I looked at the sunset with binoculars for 1 or less seconds by accident. Can I go blind? What can happen? What should I look for as symptoms? : (

No: Staring at the sun or other sources of bright light can cause solar retinopathy. This is a condition where the photo-receptors in the center of the retina become damaged, limiting the visual acuity. It cannot lead to total blindness. If you have no symptoms of decreased vision at this time, I would not be concerned. ...Read more

If symptoms develop, consult eye doctor. ...Read more

I didn't realize that I had turn my baby's car seat towards the sun. It was directly in her eyes and very bright. She is 4 mnths. Will it blind her?

I didn't realize that I had turn my baby's car seat towards the sun. It was directly in her eyes and very bright. She is 4 mnths. Will it blind her?

Not a problem: Babies at this age generally have the eyes shut much of the time. And the reflexes are already in place to avoid staring at bright lights. There is more of a risk to sunburn the skin in this circumstance than to the eyes. Nothing here to worry about. ...Read more
