    Author: McMaster PR, Wong VG, Owens JD, Kyriakos M.
    Journal: Arch Ophthalmol; 1975 Sep; 93(9):835-7. PubMed ID: 1235487.
    Abstract:
    These experiments were undertaken to determine if methotrexate therapy, initiated after immunization, could prevent the development of experimental allergic uveitis. Strain 13 guinea pigs were immunized with Strain 13 guinea pig retina-uvea extract that had been emulsified in Freund complete adjuvant. Some were treated with methotrexate twice a week until the 21st day. Each week, all of their eyes were examined with a slit-lamp. At the end of the study, some were skin tested, and the sera of selected animals were tested by immunodiffusion for antibody. The eyes of certain groups were examined histologically. Results show methotrexate prevented the development of this type of uveitis, even when therapy was initiated seven days after immunization. The disease did not appear after therapy was stopped. Methotrexate also inhibited the development of skin sensitivity and antibody to retina-uvea antigen.
