Five days ago this great horned owl was found on the ground, very emaciated and with a lacerated left cornea. Fortunately, the injury was new and with treatment, we hope we have saved his eye. Owls find their food mostly by using their exceptional hearing. Studies have shown owls can pinpoint the location of a mouse in complete darkness. So even if he does not regain perfect vision in this eye again, he will likely be able to be released.
