Figure 2. Clinical grading of experimental autoimmune uveitis. Experimental autoimmune uveitis was induced by the subcutaneous injection of 50 µg or 100 µg of peptide corresponding to 1–16 human interphotoreceptor retinoid-binding protein. The clinical grading of active and inactive lesions was performed on a scale of 0–4 at 21 and 28 days post-injection as described in Methods.
