Foveal atrophy after trauma does occur pretty frequently. Angle recession does not cause vision loss
in the early period but over a period of time glaucoma
can develop in the traumatised eye.
Unfortunately there is no treatment to foveal atrophy. Blurred vision
can be treated partially with special low vision
glasses if needed.
Glaucoma secondary to angle recession can be treated with either drops or surgery as necessary.
Yoga does not help in this case.
Hope this helps.
