Occult non‐metallic intraocular foreign body causing recurrent anterior uveitis

Purpose To describe the case of textile worker with recurrent anterior uveitis following the traumatic penetration of nylon thread into the anterior segment of the eye. Methods Examination by slit‐lamp of the affected eye B‐scan ultrasonography during the inflammatory episode and after the resolution of the uveitis. Visual Acuity Measurement during the inflammatory episode and after the resolution of the uveitis. Results The use of topical therapy together with antibiotic systemic therapy led to the regression of the inflammatory symptoms (intense epibulbar and tarsal hyperemia with perikeratic reaction, corneal sub‐oedema with some folds in the Descemet's membrane, Tyndall 2+ and a layer of lower hypopyon associated with a filamentous foreign body with a spiral shape at the base of the lower chamber. In miosis the pupil did not react to a light stimulus) and pain. Removal of the foreign body allowed the rapid resolution of the recurrent uveitis. Conclusions This case underlines the need for an accurate search for possible foreign bodies in cases of ocular traumas, even apparently slight ones, once penetration into the posterior chamber has been excluded.
