Clinical and histologic findings of an orbital lacrimal cyst (dacryops) in a 23-year-old-female red-eared slider (Chrysemys scripta elegans) are described. Main ophthalmologic findings included unilateral exophthalmus, engorged episcleral vessels, periocular swelling superior to the globe, incomplete lid closure, and reduced ocular motility. Based on sonographic and cytologic examination of the tissue, the preliminary diagnosis of an orbital cyst was established. After surgical resection of the cystic structure, the eye remained visual but enophthalmic. Histopathologic diagnosis of the resected tissue was interstitial dacryoadenitis.
