1/740. Infectious crystalline keratopathy and endophthalmitis secondary to mycobacterium abscessus in a monocular patient with stevens-johnson syndrome.

    PURPOSE: To describe the clinical and laboratory features of infectious crystalline keratopathy and endophthalmitis secondary to mycobacterium abscessus in a patient with stevens-johnson syndrome. METHOD: Case report. A 19-year-old man with a history of stevens-johnson syndrome and multiple corneal transplants developed white crystalline corneal infiltrates. RESULTS: anterior chamber aspirate disclosed acid-fast bacilli. A repeat corneal transplant was performed and antibiotic therapy begun. Histopathology showed focal acute inflammation surrounding collections of acid-fast bacilli, which were speciated as M. abscessus. CONCLUSIONS: M. abscessus is a cause of infectious crystalline keratopathy and endophthalmitis. risk factors include ocular surface disease, corneal transplantation, and immunosuppressive therapy.

2/740. Late bleb-related endophthalmitis after trabeculectomy with mitomycin C.

    To present two cases of delayed-onset postoperative endophthalmitis following trabeculectomy combined with mitomycin C for secondary glaucoma after penetrating keratoplasty. We retrospectively evaluated two patients with late endophthalmitis after trabeculectomy combined with intraoperative mitomycin C application. Both patients underwent trabeculectomy for uncontrolled glaucoma following penetrating keratoplasty and they developed thin-walled cystic blebs. intraocular pressure was normal, and grafts remained clear postoperatively. Severe endophthalmitis with hypopyon developed at 3 and 7 months postoperatively. Both patients had concomitant bleb infection. They underwent vitreous sampling and intravitreal injection of vancomycin and amikacin and were given topical fortified and systemic antibiotic therapy. Intravitreal injection was repeated once in both patients. Cultures grew streptococcus pneumonias in one and staphylococcus aureus in the other. Although the treatment of endophthalmitis was successful in both patients, only one of them achieved useful vision (20/40). For the other patient who had been infected with S. pneumoniae, vision was light perception. Delayed-onset endophthalmitis following trabeculectomy with mitomycin C application is a severe and vision threatening complication. It seems that the development of thin cystic filtering blebs secondary to intraoperative mitomycin C application may be a predisposing factor for bleb-related late endophthalmitis. ( info)

3/740. diagnosis of phacoanaphylactic endophthalmitis by fine needle aspiration biopsy.

    diagnosis of phacoanaphylactic endophthalmitis (or lens induced uveitis), a rare autoimmune disease, is difficult due to variable clinical presentation. We sought to diagnose a case based on the cytopathology of the anterior chamber aspirate. This is a case report of spontaneous phacoanaphylactic endophthalmitis in a 79-year-old woman with no history of eye trauma or surgery. After clinical examination, diagnostic anterior chamber paracentesis was performed. Cytologic examination of the aspirate revealed polymorphonuclear leukocytes, histiocytes, and plasma cells surrounding amorphous lens material. A mature cataract was removed subsequently, and the eye has remained free of inflammation postoperatively. As the clinical diagnosis of phacoanaphylactic endophthalmitis is often difficult, cytopathology of an anterior chamber aspiration specimen may be useful in diagnosing this rare, treatable condition. As far as we know, this is the first case report of the diagnosis of phacoanaphylactic endophthalmitis solely by anterior chamber fine needle aspiration biopsy. ( info)

4/740. Compound heterozygosity for one novel and one recurrent mutation in a Thai patient with severe protein s deficiency.

    Homozygous or compound heterozygous protein S (PS) deficiency is a very rare disorder in the anticoagulant system, that can lead to life-threatening thrombotic complications shortly after birth. This report describes the results of the genetic analysis of the PROS 1 genes in a Thai girl patient. She was reported in 1990 as the first case with homozygous PS deficiency and neonatal purpura fulminans. In the present report, we identified the mutations in this patient by direct sequencing of PCR products representing all 15 exons of the PROS 1 gene and their flanking intronic regions. The patient turned out to be compound heterozygous for two null mutations. One allele contained a novel sequence variation, an A-insertion in an A5-tract covering codon 146 and 147, that results in a frameshift and a stop codon (TAA) at position 155. The other allele contained a nonsense mutation in exon 12 by a transition at codon 410 CGA (Arg) to TGA (stop). Cosegregation of PS deficiency with these two genetic defects was observed in her family. ( info)

5/740. Antibiotic-induced endotoxemia in a patient with endogenous endophthalmitis.

    PURPOSE: The aim of the study is to describe a case of suspected endotoxin-induced uveitis associated with septic endogenous endophthalmitis followed by antibiotic-induced endotoxemia. methods: The human leukocyte antigen (HLA) typing of peripheral leukocytes was studied by lymphocytotoxicity technique. Histological and immunohistochemical studies of paraffin embedded specimen were conducted. RESULTS: Findings of HLA typing revealed positive reaction for B 51, Cw 3, DR 8, DR 11, DQ 3. The vitreous body of an eviscerated eye was occupied by the non-specific granulomatous tissue, composed of fibroblast, plasma cells, and sudan black staining positive foamy cells, including melaniferous phagocytes, identified as CD 68 positive macrophage. CONCLUSION: It is suggested that antibiotic-induced endotoxemia of a patient with septic endogenous endophthalmitis produced endotoxin-induced uveitis under an upregulation of HLA and endotoxin activated macrophages may release cytokines, followed by fibrin formation and subsequent granuloma.

6/740. alcaligenes xylosoxidans endophthalmitis 8 months after cataract extraction.

    PURPOSE: To report a case of alcaligenes xylosoxidans endophthalmitis and to increase awareness of its potential as an intraocular pathogen. methods: An 80-year-old woman in good general health developed A. xylosoxidans endophthalmitis 8 months after an uncomplicated cataract extraction performed at another institution. Eventually, vitrectomy with removal of the intraocular lens and capsule was performed because of recurrent disease after intravitreal antibiotic injections. RESULTS: Microbiologic examination of the vitreous biopsies and capsule disclosed A. xylosoxidans, a motile, gram-negative rod resistant to many antibiotics. CONCLUSION: A. xylosoxidans should be considered as a cause of low-grade endophthalmitis after cataract surgery. ( info)

7/740. A case of an intraocular foreign body due to graphite pencil lead complicated by endophthalmitis.

    We report a case of an 8-year-old boy who presented with an intraocular foreign body composed of graphite pencil lead. The patient had been accidentally poked in the right eye with a graphite pencil. Primary care consisted of corneal suturing and lens extraction. Two pieces of the pencil lead remained in the vitreous cavity following surgery, and 2 days later the patient developed endophthalmitis. Pars plana vitrectomy was performed immediately and the intraocular foreign bodies were removed through the scleral wound. Cultures of the vitreous fluid revealed no bacterial organisms. X-ray fluoroscopic analysis of the vitreous detected 1 ppm of aluminum (a constituent of the pencil lead). Although the clinical presentation indicated probable bacterial endophthalmitis, the detection of elemental aluminum within the vitreous cavity also suggested the possibility of further retinal toxicity due to some dissolving of the pencil lead.

8/740. pseudomonas aeruginosa endophthalmitis caused by contamination of the internal fluid pathways of a phacoemulsifier.

    PURPOSE: To report 4 cases of pseudomonas aeruginosa endophthalmitis caused by internal contamination of the internal pathways of a phacoemulsifier. SETTING: ophthalmology Center, Perpignan, france. methods: Four clinical cases of postoperative endophthalmitis occurred after phacoemulsification. An investigation was necessary to prove the cause of the bacteriological contamination. RESULTS: serotyping and ribotyping of the pseudomonas aeruginosa strains obtained from the vitreous samples and from the phacoemulsifier showed that all these strains were identical and that the initial site of the contamination was the phacoemulsifier. CONCLUSIONS: The profession should be cognizant of this cause of endophthalmitis, although its occurrence is rare. Cataract surgeons should test samples from the collection bags of their phacoemulsifiers to ensure there is no bacteriological contamination. ( info)

9/740. abiotrophia species as a cause of endophthalmitis following cataract extraction.

    Microorganisms of the genus abiotrophia, members of the oral flora, are known as important causes of bacterial endocarditis. In this study, we report two individual cases of acute vitreous infection caused by abiotrophia adiacens and abiotrophia defectiva approximately a week after cataract extraction. abiotrophia isolates were recovered by cultivation of vitreous humor on chocolate agar and identified via conventional and API 20 Strep identification systems. An 83-year-old male patient (A) and an 80-year-old female patient (B) demonstrated almost identical symptoms of infectious endophthalmitis manifested as hypopyon and opaque media. The vision of both patients was reduced to detection of hand motion in the left and the right eyes, respectively. An emergency pars plana core vitrectomy was performed, and intraocular antibiotics were administered to each patient, who presented 8 months apart in two different institutions. patients A and B were treated with an intravitreal injection of vancomycin-amikacin and vancomycin-ceftazidime, respectively, which resulted in complete recovery.

10/740. A case of bacterial endophthalmitis following perforating injury caused by a cat claw.

    A case of bacterial endophthalmitis following a perforating ocular injury caused by a cat claw is reported. The scleral wound was sutured immediately following the injury and systemic antibiotics were administered. Despite this treatment, endophthalmitis occurred 3 days after the injury. The endophthalmitis was resolved by pars plana vitrectomy, however preretinal reproliferation and retinal detachment subsequently occurred. After reoperation the retina was reattached and the corrected visual acuity improved from 10 cm/HM to 20/200. pseudomonas aeruginosa was detected in cultured vitreous humor that was collected during surgery. This case illustrates the possibility of endophthalmitis being caused by gram negative bacillus in cases of perforating injuries caused by animal claws. Perforating ocular injuries caused by animal claws are relatively rare. Here we report a case of endophthalmitis due to pseudomonas aeruginosa that occurred after a perforating injury caused by a cat claw. The eye was treated by pars plana vitrectomy. ( info)
