Define panophthalmitis/panuveitis in the context of uveitis and areas of inflammation (4).
Endophthalmitis with inflammation of the sclera, tenons capsule, and orbital tissue
Define vitritis in the context of uveitis (2). What is it usually due to?
Infiltration of inflammatory cells into the vitreous due to uveitis
