Figure 2.

Fundus images of R161H mice under germ-free (GF) or specific pathogen-free (SPF) conditions. Fundus images were taken by Micron II. WT mice (SPF or GF) do not develop spontaneous uveitis and show normal fundus. SPF R161H mice develop moderate to severe uveitis and inflammation peaks between 2–3 months of age. Diffuse lesions and inflammation along the vessels and away from the vessels are present. GF R161H mice develop milder uveitis with focal inflammation/lesions. Photos were taken at 11 weeks old except for GF WT mice at 7 weeks old.
