degenerative arthritis

asymptomatic inflammation of the eye that may lead to functional blindness)

rheumatoid nodules on the elbows, tibial crests, and fingers and may develop
erosive synovitis early in the disease

2-7%
Sex ratio:
F>>M
follows disease course similar to that in adults with RA
RF-negative:
Frequency:
11-28%
Sex ratio: F>>M
