Dacryoadenitis and extraocular muscle inflammation associated with contact lens-related Acanthamoeba keratitis: A case report and review of the literature
Özet
The present report discusses a new case of dacryoadenitis with extraocular muscle inflammation associated with Acanthamoeba keratitis (AK) in a contact lens wearer. A 41-year-old male, who has worn silicone hydrogel contact lenses on an extended basis for about 10 years, attended with the complaints of vision disturbance, hyperemia, and pain in his right eye. His history revealed that 1.5 month ago, he had been diagnosed with allergic conjunctivitis and had used steroid eye drops. Biomicroscopic examination revealed eyelid edema, chemosis, and ring infiltration, radial keratoneuritis and an epithelial defect in the cornea. Magnetic resonance imaging demonstrated enlarged lacrimal gland with edematous changes consistent with inflammation due to dacryoadenitis. There were also thickening and edema of the right superior oblique and lateral rectus muscle. The treatment protocol for AK was applied with no specific treatment for dacryoadenitis. After 4 months of the treatment, dacryoadenitis and keratitis regressed. Dacryoadenitis and extraocular muscle inflammation may accompany AK more frequently than expected and previously known. The evaluation of the lacrimal gland and extraocular muscles in presence of AK might be beneficial for understanding better the exact clinical picture and course of the keratitis.
