A Case of Salzmann's Nodular Degeneration Caused by Chronic Irritation of Dry Eye and Trichiasis

ABSTRACT

PURPOSE: To report a case of Salzmann's nodular degeneration caused by chronic irritation from dry eye and trichiasis. METHODS: A 40-year-old female patient visited our ophthalmology clinic complaining of dryness in both eyes. History taking, measurement of visual acuity and intraocular pressure, and slit-lamp examination were performed. RESULTS: We found greyish white nodular opacities which protruded from the inferior corneal surface, and trichiasis at the lower eyelids. Epilation was performed, artificial tear, and lubricating ointment were prescribed, and therapeutic lens was applied. After 3 months of treatment, the symptom was relieved and nodular opacities diminished. CONCLUSIONS: Phlyctenular keratitis, vernal keratoconjunctivitis, trachoma, scarlet fever, postoperative corneal surgery, hard contact lenses, and keratoconus are well known for the course of Salzmann's nodular degeneration. The chronic irritation from dry eye and trichiasis could be the cause of Salzmann's nodular degeneration.
