Criteria for anterior uveitis due to VZV:

(2) absence of retinitis

(3) unilateral uveitis (unless there is a positive aqueous humor PCR result for VZV)

(4) at least one of the following:

(4a) positive PCR on aqueous humor for VZV

(4b) sectoral iris atrophy AND patient is >= 60 years of age

(4c) concurrent or recent dermatomal herpes zoster
