What are some common clinical signs associated with active uveitis?

Active uveitis is characterized by inflammation within the uveal tract of the eye, which includes the iris, ciliary body, and choroid. Common clinical signs associated with this condition include photophobia, which is a sensitivity to light resulting from the discomfort caused by inflammation of the structures inside the eye. This discomfort can make the eye more sensitive to brightness. Decreased intraocular pressure is also a notable sign; during acute uveitis, inflammation can lead to decreased production of aqueous humor or increased resistance to its outflow, causing the pressure in the eye to drop.

The other options present signs that are either more chronic or associated with other ocular conditions. While glaucoma can occur as a secondary complication of uveitis, it is not a common sign of active uveitis itself. Similarly, rubeosis iridis and iris bombe refer to more advanced or secondary changes that result from prolonged or chronic inflammation of the uvea. Uveodermatologic syndrome and conjunctivitis are not specific indicators of active uveitis, as they encompass different underlying mechanisms and clinical presentations. Thus, photophobia and decreased intraocular pressure are the primary clinical signs reflective of active uveitis.
