During Wednesday’s opening of a trial for a 20-year-old Lawrence man accused of injuring a Lawrence police officer in February, two doctors testified the officer’s vision was dramatically affected by an eye injury he received.

Prosecutors accuse Louis Galloway Jr. of striking officer Jonathon Evinger in the face during an early-morning traffic stop Feb. 26 in the 2100 block of West 26th Street.

Lawrence Memorial Hospital Dr. Toni Reynolds said Evinger came into the emergency room on an ambulance with bruising to his face and left eye and that he had suffered from a concussion.

“He had confusion to the event and was suffering basically amnesia as to what happened to him,” Reynolds testified.

She said Evinger’s vision had become intensely blurry and was recorded at 20/200 at one point before it improved in subsequent days.

Dr. Scott Hickman, an ophthalmologist, said most of Evinger’s vision has returned to normal except for his peripheral vision. Evinger has not yet returned to full duty as a patrol officer.

The doctors said a blunt force would have caused the injury, but upon cross-examination from defense attorney Michael Clarke, both said they did not perform a forensic examination to determine what caused the injury.

Police have said Galloway was stopped after he was suspected of stealing 14 cases of beer from a hotel, but prosecutors have dropped misdemeanor charges related to the theft.

They are asking jurors to convict Galloway of aggravated battery of a law enforcement officer for Evinger’s injuries and misdemeanors including assault and battery on another Lawrence officer, Stephen Ramsdell.

The trial is expected to conclude Thursday.
