1/789. Streptococcal keratitis after myopic laser in situ keratomileusis.

    A 24-year-old healthy male underwent uncomplicated laser in situ keratomileusis (LASIK) in left eye. One day after the surgery, he complained of ocular pain and multiple corneal stromal infiltrates had developed in left eye. Immediately, the corneal interface and stromal bed were cleared, and maximal antibiotic treatments with fortified tobramycin (1.2%) and cefazolin (5%) were given topically. The causative organism was identified as 'streptococcus viridans' both on smear and culture. Two days after antibiotic therapy was initiated, the ocular inflammation and corneal infiltrates had regressed and ocular pain was relieved. One month later, the patient's best corrected visual acuity had returned to 20/20 with -0.75 -1.00 x 10 degrees, however minimal stromal scarring still remained. This case demonstrates that microbial keratitis after LASIK, if treated promptly, does not lead to a permanent reduction in visual acuity. ( info)

2/789. exophiala (Wangiella) dermatitidis keratitis after keratoplasty.

    We report the first French case of an intraocular infection due to exophiala (Wangiella) dermatitidis. Two months after a second corneal transplant for congenital hereditary endothelial dystrophy, the patient presented with ocular pain and corneal infiltrates leading to the graft rejection. diagnosis was established by positive direct examination and cultures of the same fungus from corneal buttons, iris biopsies and ablated sutures.

3/789. Bacterial keratitis following laser in situ keratomileusis for hyperopia.

    A 42-year-old Bahraini man had uneventful laser in situ keratomileusis for hyperopia (OD: 3.00 0.75 x 155 degrees; OS: 2.00 0.50 x 155 degrees). Three weeks later, he presented with localized keratitis in his right eye, with localized keratitis at the flap margin with stromal edema. Uncorrected visual acuity was 20/80 OD with no improvement with pinhole, and was 20/20 OS. Corneal smear culture showed a positive growth of staphylococcus aureus. The patient was immediately treated with subconjunctival gentamicin and intensive topical ofloxacin 0.3% with systemic cephalosporin. The patient recovered from keratitis within 2 weeks and his uncorrected visual acuity OD improved to 20/20. keratitis following LASIK should be treated promptly so that it does not lead to permanent reduction in visual acuity.

4/789. Fungal keratitis caused by candida utilis--case report.

    We report the first case of an ocular fungal infection caused by candida utilis in a 72-year-old woman. Although candidiasis is the most common opportunistic fungal infection in humans, C. utilis had not been associated with human morbidity until two cases of fungemia were reported in 1988 and 1993. The clinical features exhibited typical feather-like infiltration at the ulceration margin of this case. After treatment with topical fluconazole and amphotericin-B, the ulceration healed within 3 weeks. The patient underwent penetrating keratoplasty and regained useful vision. We concluded that C. utilis is a new corneal pathogen and should be included in the differential list of mycotic keratitis. ( info)

5/789. pyoderma gangrenosum complicating Cogan's syndrome.

    Cogan's syndrome is a rare clinical entity defined by the association of a nonsyphilitic interstitial keratitis and vestibuloauditory dysfunction, typically Meniere's disease-like; the condition has been reported in association with a variety of cutaneous diseases. We now report a case of pyoderma gangrenosum complicating Cogan's syndrome in a 57-year-old woman, which then healed dramatically, as more interestingly did the associated uveitis with minocycline therapy.

6/789. Exserohilum rostratum causing keratitis in india.

    A case of mycotic keratitis due to atypical Exserohilum rostratum is reported in a 42-year-old male with Hansens disease. ( info)

7/789. Cogan's syndrome with refractory abdominal aortitis and mesenteric vasculitis.

    Cogan's syndrome is a rare multisystem disease characterized by ocular inflammation, vestibuloauditory dysfunction, and vasculitis. We report a 26-year-old Caucasian woman who died from Cogan's syndrome. Her case illustrates that patients with Cogan's syndrome can have abdominal aortitis and mesenteric vasculitis, and that the vasculitis can be refractory to methotrexate, cyclophosphamide, cyclosporine, and chlorambucil.

8/789. Use of a low nutrient culture medium for the identification of bacteria causing severe ocular infection.

    A low nutrient culture medium was used to identify the pathogens in four cases of persisting ocular infection. Bacto R2A agar was used in addition to conventional liquid- and solid-phase media to culture pathogenic bacteria from one case of recurrent keratitis, one case of suture-related keratitis with endophthalmitis and two eyes (two patients) with post-operative endophthalmitis. In each case, a pathogen was identified solely with R2A agar after culture for 6 days. Species isolated were pseudomonas aeruginosa (one), propionibacterium acnes (two) and staphylococcus aureus (one). Antibiotic therapy was tailored to conform to the sensitivity of the cultured organism in each case. The use of Bacto R2A low nutrient agar should be considered in culture negative eyes not showing clinical improvement, or for chronic cases where bacteria may have become adapted to more stringent ocular environments.

9/789. Interface fluid associated with diffuse lamellar keratitis and epithelial ingrowth after laser in situ keratomileusis.

    We report a case in which diffuse interface keratitis began 1 week after bilateral uneventful laser in situ keratomileusis (LASIK). A layer of fluid in the interface with epithelial ingrowth was noted in the left eye 20 days postoperatively. The same complication occurred in the right eye 5 months after LASIK. Dry-eye syndrome and steroid-induced intraocular pressure elevation occurred in this patient with pre-existing ocular hypertension. A long course of interface inflammation was resistant to topical steroids. Surgical removal of the epithelial ingrowth and drainage of the fluid, combined with medical treatment, resulted in resolution of the inflammation. The cytopathologic examination of the fluid showed epithelial cells without signs of inflammation. The clinical features of this case represent a new complication of LASIK. ( info)

10/789. Cogan's syndrome: unsuccessful outcome with early combination therapy.

    Interstitial keratitis and vestibuloauditory symptoms (vertigo and hearing loss) are the typical signs of Cogan's syndrome, a rare inflammatory vascular disease. Signs of vasculitis in many organ systems may appear, among which neurologic problems are sometime predominant. The efficacy of glucocorticoids on the ocular and systemic symptoms is established, but their effect on hearing loss is unknown. We describe a case of Cogan's syndrome with neurological involvement in which early treatment with combination therapy (prednisolone and cyclosporin) failed to bring ear inflammation under control.
