We report the case of a 58-year-old woman who developed filamentary keratitis after undergoing uncomplicated strabismus surgery for exotropia secondary to third-nerve palsy with a large head turn and incomitant left exotropia. Her symptoms were controlled after a bandage contact was used. No similar cases of filamentary keratitis occurring after strabismus surgery have been reported. Filamentary keratitis is usually associated with symptoms of ocular irritation and foreign-body sensation. Filamentary keratitis occurs in association with numerous disorders: keratoconjunctivitis sicca, superior limbic keratoconjunctivitis, epidemic keratoconjunctivitis, postcataract extraction,1 post-penetrating keratoplasty,2 neurotrophic keratitis,3 herpetic keratitis, bullous keratopathy, eyelid occlusion,4 brain stem injury,5 diphenhydramine hydrochloride use,6 hereditary hemorrhagic telangiectasis, 7 retrobulbar injection of botulinum toxin,8 and anticardiolipin antibodies.9 The exact pathogenesis of this entity remains unclear.10 Filament formation results from a derangement in the corneal epithelium and a relative excess of mucus. The excess mucus is usually secondary to chronic irritation, and the location of the filaments depends on the type of underlying corneal pathology.
