1Private Practice and Hospital Ángeles del Pedregal, México City, Mexico.
Purpose:
To describe a case of keratouveitis caused by Euphorbia grandicornis sap, that resolved with topic steroids.
Methods:
We report a case presentation of a patient with keratouveitis.
Results:
A 70-year-old woman suffered from accidental ocular contact with E. grandicornis sap in her left eye. Two hours after the contact, she attended the clinic due to conjunctival hyperemia and pain. Best-corrected visual acuity (BCVA) was 20/25. The toxic conjunctivitis was treated with topical lubricant and steroid. After 24 h, she presented blurred vision. BCVA was 20/80. Toxic keratouveitis was diagnosed. Topical treatment with 1% cyclopentolate t.i.d., 5% sodium chloride, 1.14% dexamethasone phosphate each hour, and 4% sodium hyaluronate each hour was continued. Complete resolution was obtained 1 week later. Euphorbia sap content analysis was performed using dissolvent extraction spectrophotometry. Its contents included flavonoids, alkaloids, phenols and sesquiterpene lactones.
Conclusion:
Corneal exposure to E. grandicornis sap is a cause of nonvisually threatening keratouveitis when adequately treated with corticosteroids.
