Atopic keratoconjunctivitis with corneal ulcer. Case report.

: Purpose: To report the case of a 14-year-old male patient, with bilateral atopic keratoconjunctivitis with corneal ulcer. Methods: The patient complained of bilateral red, itchy eyes, decreased vision, photophobia, difficulty opening the eyelids upon awakening, palpebral edema, excessive tearing, along with yellowish mucous discharge. He had a two-year history of chronic blepharitis and recurrent episodes of conjunctivitis that were treated with Tobramycin and corticosteroid eye drops over the years. The patient's past medical history was significant for atopic dermatitis (AD) and he had a family history for atopy. At the eye exam: his best-corrected visual acuity at the initial presentation was 0.2 in the right eye and 1.0 in the left eye. The following elements were found upon the slit lamp biomicroscopy: Eyelids - +4 palpebral edema (pseudoptosis), Dennie-Morgan fold and Herthoge's sign were both present, tylosis; Conjunctiva - hyperaemia, cobblestone appearance of the tarsal papillae in both eyes, +2 chemosis; Cornea - corneal edema with a 8 mm × 4 mm epithelial defect in the inferior part of the cornea, covered partially by the lied, that stained positive with fluorescein dyes. Using the Evaluation Signs Severity for Allergic Ocular Diseases, a diagnosis of bilateral atopic keratoconjunctivitis with a grade 3 status for the right eye and a grade 2 status, was made. It was decided that he should be administered Olopatadine hydrochloride and Sodium cromoglicate eye drops, along with Moxifloxacin and steroid eye drops. The microbiological exam tested positive for staphylococcus aureus, and, based on the sensitivity pattern, Chloramphenicol eye drops had to be added to the treatment. After 2 weeks, his symptoms diminished, pain was significantly relieved and inflammation was markedly reduced, but the corneal ulcer persisted. In order to prevent corneal perforations, amniotic membrane transplantation (AMT) was used to promote epithelialization. Results: A month later, the epithelial defect healed smoothly in an underlying vascular stromal scar and the visual acuity improved to 0.4 RE. Conclusions: This case demonstrated the role of patient history and close clinical obser-vation in the diagnosis of AKC. As this case showed, the use of topic medication along with amniotic membrane transplantation (AMT) was successful in the treatment of atopic keratoconjunctivitis and secondary staphylococcal aureus keratitis.
