1/4. Infectious keratitis after photorefractive keratectomy in a comanaged setting.A 48-year-old man had simultaneous bilateral photorefractive keratectomy (PRK). The surgeon who performed the PRK did not see the patient in follow-up, and there was confusion regarding the comanaging doctor. Therefore, the patient was not examined immediately postoperatively. Several days later, he was hospitalized for an unrelated, painful orthopedic problem and heavily sedated. Seven days after the PRK, an ophthalmologist was consulted for ocular irritation and discharge. Examination showed bilateral, purulent conjunctivitis and severe infectious keratitis in the left eye. The patient was treated with periocular and topical antibiotics. Corneal cultures yielded Staphylococcus aureus. The keratitis resolved slowly, leaving the patient with hand motion visual acuity. A corneal transplant and cataract extraction was performed 15 months later, resulting in a best corrected visual acuity of 20/400 because of glaucomatous optic nerve damage. Severe infectious keratitis may occur after PRK. Poor communication between the surgeon, comanaging doctor, and patient may result in treatment delay.- - - - - - - - - - ranking = 1keywords = aureus (Clic here for more details about this article) |
2/4. The giant fornix syndrome: an unrecognized cause of chronic, relapsing, grossly purulent conjunctivitis.AIM: To describe a group of elderly patients presenting with chronic, relapsing, copiously purulent conjunctivitis, in which the condition was often perpetuated by the sequestration of a large number of bacteria on a protein coagulum lodged in the recesses of a large upper conjunctival fornix. patients AND methods: Retrospective review of a noncomparative case series, drawn from patients attending the lacrimal clinic at Moorfields eye Hospital. OUTCOME MEASURES: Characterization of this unrecognized syndrome and its response to treatment. RESULTS: Twelve patients (10 female) presented between the ages of 77 and 93 years (mean, 85; median, 86) with a history of chronic relapsing bacterial conjunctivitis affecting, with 2 exceptions, just one eye. All had experienced multiple episodes of markedly purulent conjunctivitis and chronic ocular discharge for between 8 and 48 months (mean, 23.5; median, 24) before referral, and the patients had received multiple courses of treatment. Three had successful external dacryocystorhinostomy (for nasolacrimal duct occlusion) before the final diagnosis of giant fornix syndrome was made, 9 had developed corneal vascularization and scarring before referral, and 5 had suffered prior spontaneous corneal perforation or thinning. All patients had deep upper conjunctival fornices in association with the changes of age-related dehiscence of the levator muscle aponeurosis. Copious amounts of thick, purulent debris and a yellow coagulum were lodged in the depths of the upper fornix-this debris universally culturing Staphylococcus aureus. The condition settled rapidly on appropriate systemic antibiotics (ciprofloxacin or ofloxacin), intensive topical antibiotics, and high-dose, high-potency steroids; some patients required repeated treatment or needed to continue the use of a single drop of a combined steroid-antibiotic to prevent relapse. CONCLUSION: The capacious upper fornix of the elderly may harbor a coagulum colonized by S. aureus, leading to chronic conjunctivitis that may lead to severe sight impairment due to toxic keratopathy and secondary corneal vascularization.- - - - - - - - - - ranking = 2keywords = aureus (Clic here for more details about this article) |
3/4. Recurrent staphylococcal conjunctivitis associated with facial impetigo contagiosa.PURPOSE: To report the uncommon occurrence of impetigo contagiosa in the setting of recurrent staphylococcal conjunctivitis. DESIGN: Interventional case report. methods: A 32-year-old patient had a recurrent painful red left eye and facial rash. Clinical examination revealed left bacterial conjunctivitis and facial bullous impetigo. microbiology cultures were taken from the nose, conjunctiva, and facial lesions. RESULTS: Microbiologic cultures grew Staphylococcus aureus, and hematology findings demonstrated an elevated white cell count with neutrophilia. Complete resolution was achieved with topical chloramphenicol ointment and oral dicloxacillin. CONCLUSIONS: Although uncommon, bullous impetigo may be associated with recurrent staphylococcal conjunctivitis in adults. Recurrent infections may require nasal decolonization, systemic antibiotics, and antiseptic body wash.- - - - - - - - - - ranking = 1keywords = aureus (Clic here for more details about this article) |
4/4. Topical vancomycin for the treatment of staphylococcus epidermidis and methicillin-resistant staphylococcus aureus conjunctivitis.Staphylococcus aureus and staphylococcus epidermidis are organisms that frequently cause conjunctivitis or blepharoconjunctivitis. We describe a patient with methicillin-resistant S. aureus and S. epidermidis conjunctivitis who was treated successfully using an extemporaneously prepared topical ophthalmic solution of vancomycin hydrochloride 31 mg/mL. Studies describing the preparation, stability, and comfort of this solution, as well as reports pertaining to efficacy, are reviewed. Controlled clinical trials evaluating the safety and efficacy of vancomycin ophthalmic solution have not yet been performed.- - - - - - - - - - ranking = 6keywords = aureus (Clic here for more details about this article) |
