NORRISTOWN, Pa. (AP) -Lawyers in Bill Cosby’s sexual assault case say his eyesight has deteriorated to the point he can no longer identify his accusers in photographs or otherwise help the defense.

The 79-year-old Cosby leaned back in his chair Wednesday as his lawyers tried to get a felony charge dismissed before his June trial in Pennsylvania.

Prosecutors want 13 other accusers to testify to bolster a woman’s account that Cosby drugged and molested her in 2004.
Defense lawyer Angela Agrusa says prosecutors unfairly prejudiced Cosby by waiting a decade to pursue Andrea Constand’s complaint. She says his vision and memory problems leave him unable to defend himself.

Prosecutors say they reopened the case last year amid new evidence and they’re not sure of the extent of Cosby’s vision problems.
