My friend, when he was a child met with an accident with a sharp object in his eye. He lost his eye sight due to that and now he has only a partial eye sight to that eye (can detect only shapes which are close and that too with blur). His eye pupil lost it's normal exact circular shape. He can see with his other eye and due to this, he got squint too. Now he wants to get back his vision to his eye. Question: 1. Is it possible to get back the vision back completely? 2. What is the problem and it's name which caused this condition to him? 3. Such kind of treatment or what should be done to get back his eye sight completely. Note: Somebody told him, there may be optical nerve damage. Is it true? If yes, then what should be done to get back his eye sight completely?

Hello. Sorry about your friend's eye problem. Coming to your first question: unfortunately, it would not be possible to get back complete vision in the damaged eye. Vision lost during childhood is difficult to recover after so many years. The initial years of life are the ones that determine the growth and development of the eye. During this period the eye learns to see. Once the vision is compromised during childhood, there is very less chance of recovering it at such a late stage. Coming to your second query, the name of the condition would be amblyopia (post traumatic) or lazy eye. Also, there may be associated wound related scars and structural defects in the eye. There may be damage to the retina, lens or the cornea of the eye. As you mentioned, damage to the optic nerve may have caused optic atrophy in the eye. Regarding to your third question, it might be possible to treat him for the squint. The misalignment of the eyes could be rectified by surgery but it would not recover vision for him. Once again, sorry for your friend. Take care.
