Dear u have got Traumatic Optic Atrophy
for which unfortunately there is no treatment at present but research is going on!!!
In brief i would like to explain what it is - Our eye is connected with the brain through a fine and delicate structure called as Optic nerve
which in fact is made up of millions of fine filament like structure. It passes from eye to brain thru very narrow and compact bony canal which in few cases get hurt/fractured. After fracture the nutrition of the nerve compromised and it gets thinned out gradually and ultimately Atrophied. There is no treatment to rejuvenate this atrophied nerve.
I hope u may satisfy with this answer
