The eight-year veteran has not played since sustaining permanent eye damage against the Jacksonville Jaguars on Dec. 19.
"We are convinced that there is absolutely no light at the end of the tunnel in terms of Orlando returning to the playing field in 2000," Browns' president Carmen Policy said.
"I would have had a difficult time putting him back on the field in view of his personal concerns and his inability to recover from the injury," Browns' head coach Chris Palmer added.

Brown was inadvertently struck in the right eye by a weighted penalty flag thrown by referee Jeff Triplette.
The hulking, six-foot-seven, 350-pound offensive tackle immediately dropped down to one knee in obvious pain.
He momentarily staggered towards the sideline before turning back onto the field to shove Triplette to the turf.
NFL commissioner Paul Tagliabue promptly suspended Brown indefinitely.
The penalty was lifted two months later, but Brown has been unable to work out, weight train or even jog.
When he complained of blurred vision as recently as Aug. 27, the Browns placed him on the physically-unable-to-perform list.
"The symptoms have not subsided and we do not think he is close to being approved by the doctors to return to play," Policy said.
"I'm worried about him and everybody connected to the Cleveland Browns is worried about him."
"It wasn't the Browns," said Brown, who blames the NFL for his predicament.
Brown has retained lawyer Johnnie Cochran Jr. to explore the possibility of a lawsuit against the league.
