What do you think the the Pt has? Is the uveitis secondary to anything? What are the likely auto-immune possibilites?

Answer by Dr Alicia
The 'low' values aren't really that low. they are really borderline.
I would say the patient just has uveitis.
these low levels may be normal for that patient.

as to the autoimmune possibilities, uveitis can itself be autoimmune
