Ciliary Body Mass as a Feature of Ocular Sarcoidosis.

Importance: Ocular sarcoidosis may be the primary and only clinical manifestation of sarcoidosis, and irreversible loss of visual acuity may occur from delayed treatment. Thus, early diagnosis is imperative to preserve visual acuity. Establishing the diagnosis of sarcoidosis in cases manifesting only in the eye may require a diagnostic biopsy, which may prove challenging in the absence of available ocular surface, lacrimal gland, and systemic tissue for biopsy.
