Osamu Hieda, Norihiko Yokoi, Chie Sotozono Department of Ophthalmology, Kyoto Prefectural University of Medicine, Kyoto, Japan Purpose: To report a case of filamentary keratitis occurring in the cornea hidden under the eyelids by squint surgery.Methods: A 69-year-old female patient with a history of amblyopia was referred for intractable filamentary keratitis in the left eye. The strabismus angle was 35Δ hypertrophic, and ocular motility was within the normal range. Slit-lamp examination of her left eye revealed filamentary keratitis in more than one-third of the upper cornea behind the upper eyelid. Her right eye was diagnosed as supranuclear double elevator palsy. We performed strabismus surgery on her right eye, including inferior rectus muscle recession (5 mm) in combination with superior rectus muscle resection (5 mm) under local anesthesia. Following surgery, the left eye squint angle was improved. The filamentary keratitis of the left eye disappeared, and there was no recurrence over the following 5 years.Conclusion: The squint surgery of paralyzed right eye decreased the strabismus angle, subsequently resulting in the disappearance of the filamentary keratitis in the left eye via the resolution of the relative blepharoptosis. Although the squint operation performed was not for the purpose of improving binocular function, we want to conclude that it can treat the filamentary keratitis behind the eyelid.
