Clinico-Microbiological Profile of Bacterial Keratitis in Shield Ulcers Jagadesh C. Reddy Abhishek Arunkumar Hoshing, Virender S. Sangwan The authors have no financial interests in the subject matter of this presentation ID: 17668

Purpose The purpose of this study was to describe the clinico-microbiological profiles and outcomes of treatment of bacterial keratitis in patients with shield ulcers due to vernal keratoconjunctivitis (VKC)

Methods Study design: Retrospective review of clinical records Study location: Cornea service, LV Prasad Eye Institute, India Study duration: January 2000 to December 2012 Study ethics: Approved by the institutional review board and was conducted in strict adherence to the tenets of the Declaration of Helsinki

Methods Data collected: Demographics Clinical features History of allergy Duration of VKC Visual acuity Culture & sensitity of organisms Duration of use of antibiotics and steroids, Resolution time Complications

Results Number of eyes33 Age, years11 +/- 6 years Gender, Mala : Female27:5 Laterality, Right eye : left eye 20:13 Duration of Vernal kerato conjunctivitis 44 +/- 35 months Duration of symptoms17 +/- 20 days Type of Vernal kerato conjunctivitis Mixed : 82% Palpebral: 18% Table-1, Patient characteristics

Results At presentation, 9 (27%) patients were antibiotics, 2 (6%) patients on antifungals, 9 (27%) patients on steroids and 14 (42%) patients on antiallergic topical medications Based on smear examination fortified Cefazolin and Ciprofloxacin eye drops were started which were modified based on sensitivity report Topical antibiotics were used for at least a mean of 17 days Steroids were started simultaneously in 15 % of patients In 85% of eyes the steroids were started at least after 8 days (mean) of topical antibiotic usage

Conclusions Bacterial keratitis in shield ulcers due to VKC usually resolves completely with medical management Clinical diagnosis of secondary infection in a shield ulcer is a diagnostic challenge but thorough history and clinical features aid to a great extent The organisms isolated are sensitive to most of the commonly used antibiotics
