Conjunctival Proliferation After a Mild Pepper Spray Injury in a Young Child

PURPOSE To report a case of conjunctival proliferation in a 2.5-year-old boy after initial evidence of a mild chemical injury after ocular exposure to pepper spray (oleoresin capsicum). METHODS Case report with ophthalmologic and histologic findings. RESULTS A child presented with mild conjunctival injection and chemosis without any corneal erosion after direct exposure to pepper spray. Three weeks later, a significant conjunctival proliferation was found at the limbus, which was refractory to treatment with topical corticosteroids. Finally, proliferative tissue was surgically excised without clinical recurrence during 2 months of follow-up. CONCLUSIONS We hypothesize that the young age of the patient may have been an important factor for the severe conjunctival proliferation in comparison to a mainly uncomplicated course of pepper spray injuries in most adults. We recommend the use of topical antiinflammatory treatment even in apparently mild pepper spray injuries, especially in young children.

Association of bilateral acute anterior uveitis with a capsaicin patch

PURPOSE To report a case of bilateral acute anterior uveitis in association with the application of an analgesic transdermal capsaicin patch. METHODS Case report and review of literature. RESULTS A 38-year-old woman suffered from bilateral acute anterior uveitis, manifesting 12-24 h after application of an analgesic capsaicin patch (Isola Capsicum N Plus) that served to alleviate muscular neck pain. Systemic immune-mediated and infectious diseases were excluded by medical history and laboratory testing. Control of inflammation was achieved with topical corticosteroid treatment within 1 week. Over the course of a 1-year follow-up, no further recurrence of uveitis was observed. CONCLUSIONS The case suggests a possible association of capsaicin-containing transdermal patches and acute anterior uveitis.
