I currently have lots of Bluegill with eye injuries, some so effected from more than a year. Orientation in water generally not effected. What does impact orientation involves the inner ears. Sometimes an angling injury will damage one of the inner ear components. Damage need not be direct if swelling impacts a semicircular canal. I have treated some successfully by a combination of time and antibiotics. Most do not regain normal swimming pattern. I assume those do not have direct injury to inner ear.
