Symptoms of uveitis can range from ocular redness, aching, and sensitivity to light, to blurred vision and floaters in the vision. Eyelid nodules and orbital nodules can affect ocular movement, and in some cases, cause protrusion of the eye itself. In some cases, nodules of the conjunctiva can occur. Biopsy of conjunctival or lacrimal gland nodules can be useful for diagnosis. The cause of sarcoidosis is unknown.
Treatment is by anti-inflammatory agents, most commonly steroids by mouth.
Since the disorder tends to be chronically recurrent, the amount of steroid is titrated to the level of disease activity. In some cases, sarcoid has only a mild, self-limited course. In more severe cases, or in those affecting the central nervous system, stronger anti-inflammatory agents such as cyclophosphamide may be needed. Ocular steroids, usually in the form of eyedrops, can control inflammation, but may lead to complications of cataract and glaucoma. There are common ocular complications during all stages of Lyme disease.
