New Study Helps to Treat Lazy Eye in Adults
Researchers at the University of Maryland have developed a method that helps an adult recover function in an eye that has been damaged and dysfunctional from birth.

The study may help treat Amblyopia, or lazy eye as it showed that complete visual loss promoted subsequent recovery in an eye that has had severely compromised vision throughout life.

Clinical studies have demonstrated that the probability to recover amblyopia, caused by unilateral cataract, depended on the age at which the cataract was removed. The probability to recover fully was maximum when the cataract was removed by the age of three.

As part of the study Hai-Yan He, Baishali Ray and Katie Dennis, by blocking the input into one eye from eye-opening to adulthood, mimicked a unilateral cataract in a rodent model.

Similar to what cataract does, the experimental occlusion caused rapid fall in deprived eye's acuity. Earlier researches have established that an eye cannot recover normal visual function if the occlusion was removed in adulthood.

"However, when we placed the subjects into a light-tight dark room for a period of complete visual deprivation prior to removing the occlusion, we were able to produce a rapid recovery of visual acuity after removal of the occlusion" Nature quoted Yan He, as saying.

"Dark exposure drives down the strength of the synapses serving the two eyes, restoring the symmetry that was previously lacking in the amblyopic adult," Quinlan said.

"The decrease in synaptic strength combined with the restoration of symmetry may allow the visual cortex to be more plastic and respond to changes in subsequent visual input," Quinlan added.

I'm 63 years old and have had amblyopia "lazy eay" in my right eye since birth. I noticed that may of you have commented on your lack of confidence; don't let this condition take hold of your life and or your amibtion. You can do what ever you set your mind to do, don't let a visual imperfection get in your way. I have worked all my life as an engineer, have 3 kids and a lovely homne in Texas. I am and have always been very confident in my abilities. I do what ever I want to do whan I want tgo do it. I've played baseball and football ... never an allstar but that was due to drive not eyesight. Found out I would rather use my brain than my body. Don't let this condition bring you down!!!
