title: [Does a iatrogenic damage caused by dacryography exist?].
abstract: This study was aimed at investigating the changes in corneal epithelium caused by dacryocystography. Such changes can be either chemical--from iodate contrast media (iodized oil and water-soluble non-ionic cm)--or physical--from needle or catheter. Twenty-five patients (50 eyes) were studied using BUT, Schirmer tests, biomicroscopy, and pachymetry. Follow-ups immediately after dacryocystography demonstrated superficial keratitis, which was less severe with water-soluble non-ionic cm. Such lesions were hardly ever observed in patients who had been treated with dacriosol ointment on the cornea just before the X-ray exam. Follow-ups at 24 hours showed the superficial keratitis to have disappeared in all patients, independent of the kind of cm employed and of the ophthalmic ointment applied to the cornea.
