Interpretation of the electro-oculogram of patients taking chloroquine.

No significant differences in initial EOG were found between a group of RA patients using chloroquine, a group treated with gold and a normal group. Most probably this is due to the low dosage of chloroquine which is used nowadays. After six months, EOG values in the chloroquine group were reduced, while they were increased in the gold group. The differences were statistically significant, but most be carefully interpreted, because in the group of normal subjects the EOG was lowered as well.
