Abstract
To study predisposing factors, clinical aspects, and microbiological diagnosis in severe microbial keratitis, and to discuss the therapy and visual outcome. and methods: A prospective and retrospective study concerning patients presenting microbial keratitis hospitalized in department B of the Hedi Raies Ophthalmology Institute (Tunis, Tunisia), from August 1996 to November 2004. One hundred patients with microbial keratitis were hospitalized (45 females and 55 males; ranging in age from 11 to 87 years). The principal predisposing factors were ocular surface pathology (30%), ocular trauma (28%), prior ocular surgery (17%), and contact lens wear (8%). The corneal scraping culture was positive in 42% of cases, isolating Gram-positive bacteria (48.6%), Gram-negative bacteria (29.7%), and fungi (21.6%). The majority of our patients (93%) had broad-spectrum topical antibiotics with therapeutic success in 53.8% of cases. Systemic antifungal agents were indicated in 17 cases. Surgery was necessary in 25.8% of cases: therapeutic keratoplasty in five cases and deleted keratoplasty in nine cases. Final visual acuity was equal to or better than at admission in 81% of cases. Anatomic loss of the eye was observed in eight cases (evisceration, six cases; enucleation, two cases). microbial keratitis is a frequent and severe pathology that can lead to blindness. Only early and adapted management can improve the prognosis of severe microbial keratitis.
