Is It Possible To Go Blind From Not Fixing A Lazy Eye
? fixing ?: Sometimes people use terms differently than us docs. To us lazy eye refers to the vision loss caused when the brain decides to ignore or turn off the input of a weaker or misaligned eye. If your eyes don't line up properly that is strabismus & the double image it causes forces the brain to turn one off. If someone strengthens a weak eye or gets them straight soon enough it may save vision. ...Read moreSee 2 more doctor answers
Yes: The process of lining up the fixation point is part of visual development and brings the eyes into alignment. However if one eye presents a clearer image to the brain than the other, the brain may later decide to turn off the out of focus eye and thus create amblyopia. Misaligned eyes present a constant double image to the brain so one is turned off to have a clear image.The brain decides. ...Read more
Rx May help: Lazy eye is the process where the brain ignores the "camera" picture from one eye because it is less clear or causes double vision. It can sometimes be improved if the weaker eye is strengthened (glasses), the stronger eye is patched or if the eye is lined up better with surgery. If the process has gone on too long, the brain ignores the fix & surgery is simply cosmetic. ...Read more
In a sense: "lazy eye" is an eye which drifts from straight ahead usually due to visual problems from infancy and childhood. Some adults have compensated for this in the sense that they hold the eyes in a good position while alert. Those that do this can find that the eye which is seeing less well might drift if they get tired. As long as this is controlled most of the time, it can be ignored. ...Read more
Yes: Most people do adapt to floaters that are blocking the vision, often with the brain "filtering out" the floater so that it is only bothersome in certain situations. Unfortunately, the only sure treatment would be surgical removal of the vitreous gel that fills the back of the eye (and this is generally not recommended unless floaters are persistantly and extremely unusually troublesome). ...Read more
Possibly: The most common 'wandering eye' is when vision is down in one eye and it cannot hold fixation and moves in or out compared to the other eye. There is a condition called alternation in which either eye can achieve fixation while the other snaps out or in. If there is poor vision in both eyes, they can wander in a random pattern termed nystagmus. ...Read more
Rx May help: Ambliopia is the process where the brain ignores the "camera" picture from one eye because it is less clear or causes double vision. It can sometimes be improved if the weaker eye is strengthened (glasses), the stronger eye is patched or if the eye is lined up better with surgery. If the process has gone on too long, the brain ignores the fix & surgery is simply cosmetic. ...Read more
If the person is blind is there any possible treatment that the blind eye back to a normal vision?
Depends: Everything depends on the reason for blindness. If it is acquired cataract or other media opacity usually vision can be restored. Retinal and optic nerve causes of blindness can usually not be remedied. Lazy eye blindness (amblyopia) can only be repaired in the first few years of life. ...Read more
No: Eyes misaligned can only be straighted at your age by proper surgery. ...Read more
No: Amblyopia (lazy eye) develops when one eye is not used early in life. This is usually due to not using both eyes together due to eye position (ie. Crossed), or amount of eyeglass correction. If not caught early in life the brain does not make the proper connections to see well out of that eye. If the amblyopia is due to eye position eye muscle surgery at a young age may help. ...Read moreSee 1 more doctor answer
