This is a cross sectional study of a novel non-invasive optical flare photometer (OFAM). Patients meeting the inclusion/exclusion criteria will receive a standard eye examination including a slit lamp examination to collect ocular flare data. In addition to the standard eye examination, subjects will receive flare measurements using the OFAM device.

Inclusion Criteria:

• Ability to understand and willingness to sign a written informed consent document.
• To be eligible for the uveitis arm of the study subjects must have active anterior chamber uveitis in one or both eyes as determined by a physician
• To be eligible for the non-inflammatory arm of the study the study subjects must have no ocular inflammation in either eye as determined by a physician.

Exclusion Criteria:

• Inability to give informed consent
• Exclusion criteria for the uveitis arm: no active disease
• Exclusion criteria for the non-inflammatory arm: Signs of uveitis

All patients with uveitis seen in the uveitis clinic at the UW Medicine Eye Institute would be eligible for participation in the uveitis arm of the study (n ≤ 50). Patients with other, non-inflammatory forms of eye disease will be eligible for the non-inflammatory arm of the study (n ≤ 50).
