    D) Uveitis
    Perilimbic redness is associated with uveitis, keratitis, and acute glaucoma.
    Conjunctivitis is typically allergic, chemical, bacterial, or viral, spares the limbic area (junction between the sclera and cornea), is painless, and is associated with eye discharge. Vision is not affected unless discharge obscures the visual axis.
    Episcleritis is inflammation of the thin vascular tissue between the conjunctiva and sclera, and is usually isolated and self-limited. It presents as abrupt onset bright redness emanating radially outward from the limbus, with irritation but not significant pain, watering, and normal vision. It can be distinguished from conjunctivitis by moving the conjunctiva (in episcleritis, the redness does not move).
    Keratitis is inflammation of the cornea. It causes vision problems, severe pain, photophobia, and perilimbic redness. Infections commonly cause it, but other problems such as contact lens complications and “snow blindness” can also cause it.
    Scleritis is extremely painful, often associated with systemic (eg autoimmune) disease, and results in redness and edema of the sclera.
    Uveitis is inflammation of the middle layer of the eye, between the retina and the cornea/sclera. It is associated with inflammatory (infectious and rheumatologic) diseases. Anterior uveitis is also called iritis, and may be caused by trauma. Symptoms may include vision problems, pain, perilimbic redness, and cell “flare” in the anterior chamber on slit lamp exam.
