Factual and procedural background
Aaron Lindh worked as a police officer for the City of Petaluma. During a canine training course, Lindh received three to six blows to the left side of his head. Following the injury, Lindh began suffering severe headaches that lasted for several hours. A month following the work-related injury accident, Lindh lost nearly all of the vision in his left eye. Lindh saw two different doctors. Neither of the doctors attributed his vision loss to the work accident. Lindh submitted a claim for workers’ compensation for his disability.
