1/78. 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.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
2/78. 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.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
3/78. haemophilus influenzae associated scleritis.AIMS: To describe the clinical course and treatment of haemophilus influenzae associated scleritis. methods: Retrospective case series. RESULTS: Three patients developed scleritis associated with ocular H influenzae infection. Past medical history, review of systems, and laboratory testing for underlying collagen vascular disorders were negative in two patients. One patient had arthritis associated with an antinuclear antibody titre of 1:160 and a Westergren erythrocyte sedimentation rate of 83 mm in the first hour. Each patient had ocular surgery more than 6 months before developing scleritis. Two had cataract extraction and one had strabismus surgery. Nodular abscesses associated with areas of scleral necrosis were present in each case. culture of these abscesses revealed H influenzae in all patients. Treatments included topical, subconjunctival, and systemic antibiotics. Scleral inflammation resolved and visual acuity improved in each case. CONCLUSION: H influenzae infection may be associated with scleritis. Accurate diagnosis and treatment may preserve ocular integrity and good visual acuity.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
4/78. Postoperative endophthalmitis caused by sequestered acinetobacter calcoaceticus.PURPOSE:To describe postoperative endophthalmitis caused by sequestered acinetobacter calcoaceticus.METHOD:Case report. A 40-year-old woman developed recurrence of inflammation after extracapsular cataract extraction with intraocular lens (IOL) implantation. At last recurrence, the capsular bag was studded with white deposits. Intraocular lens was removed along with capsular bag during pars plana vitrectomy.RESULTS:The capsular bag, when cultured, grew A calcoaceticus. The media remained clear with no evidence of recurrence of infection over a 3-month follow-up. CONCLUSION:Postoperative endophthalmitis similar to that caused by sequestered propionibacterium acnes can be caused by A calcoaceticus.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
5/78. The expanding clinical spectrum of ocular lyme borreliosis.OBJECTIVE: To delineate the clinical manifestations of ocular Lyme borreliosis, while concentrating on new symptoms and findings and the phase of appearance of ophthalmologic disorders. DESIGN: Observational case series. PARTICIPANTS: Ten patients with Lyme borreliosis-associated ophthalmologic findings previously reported from the Helsinki University Central Hospital in addition to 10 new cases that have since been diagnosed. INTERVENTION/TESTING: The patients underwent medical and ophthalmologic evaluation. The diagnosis of Lyme borreliosis was based on medical history, clinical ocular and systemic findings, determinations of antibodies to borrelia burgdorferi by enzyme-linked immunosorbent assay and immunoblot analysis, the detection of dna of B. burgdorferi by polymerase chain reaction, and exclusion of other infectious and inflammatory causes. MAIN OUTCOME MEASURES: Ocular complaints, presenting ophthalmologic findings, and the stage of Lyme borreliosis were recorded. RESULTS: Four patients presented with a neuro-ophthalmologic disorder, five had external ocular inflammation, 10 patients had uveitis, and one had branch retinal vein occlusion. One patient developed episcleritis and one patient developed abducens palsy within 2 months of the infection incident. In the remaining 14 patients in whom the time of infection was traced, the ocular manifestations appeared in the late stage of Lyme borreliosis. Two patients with a neuro-ophthalmologic disorder and one with external ocular inflammation experienced severe photophobia, whereas the main reported symptom of the patients with uveitis was decreased visual acuity. Four patients with external ocular disease and one with a neuro-ophthalmologic disorder experienced severe periodic ocular or facial pain. retinal vasculitis developed in seven patients with uveitis. CONCLUSIONS: Lyme borreliosis can cause a variety of ocular manifestations, which develop mainly in the late stage of the disease. photophobia and severe periodic ocular pain can be characteristic symptoms of Lyme borreliosis. In the differential diagnosis of retinal vasculitis, Lyme borreliosis should be taken into account, especially in endemic areas.- - - - - - - - - - ranking = 2keywords = inflammation (Clic here for more details about this article) |
6/78. Mycobacterium keratitis after laser in situ keratomileusis.PURPOSE: The authors report two cases of Mycobacterium keratitis following LASIK. methods: The case reports are based on a retrospective review of clinical history and associated findings. RESULTS: Two patients developed infectious keratitis after undergoing laser in situ keratomileusis (LASIK). In case #1, the infection developed after manipulation of the lamellar flap to remove epithelium from the stromal bed. In case #2, prior radial keratotomy may have been a contributing factor to development of the infection. Corneal infiltrates appeared as focal, white, stromal deposits. Cultures isolated mycobacterium fortuitum from case #1 and mycobacterium chelonae from case #2. Topical fortified amikacin, clarithromycin, tobramycin, and ciprofloxacin eventually controlled the infection. Topical prednisolone acetate and bandage contact lenses were necessary to control inflammation and pain. Infiltrates were slow to resolve until focal necrosis eroded through the flaps leading to rapid clearing of the infiltrates; however, scarring of the cornea developed at the site of necrosis. Visual recovery was good in the first case but limited in the second. CONCLUSIONS: Mycobacterium keratitis complicating LASIK may be difficult to eradicate until the sequestered stromal infiltrate drains. Rapid recognition of the causative organism and aggressive medical and surgical management of the infection may improve the outcome.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
7/78. A devastating ocular pathogen: beta-streptococcus Group G.PURPOSE: To report the clinical findings, treatment, and outcomes of four cases of beta-streptococcus Group G (BHS-G) ocular infection. methods: The medical and microbiologic records of four cases of BHS-G ocular infection were retrospectively reviewed. RESULTS: Two cases of BHS-G endophthalmitis and two cases of BHS-G keratitis were recorded. Three patients developed fulminant infection within 12 hours of the onset of symptoms. One patient's history was incomplete. One patient developed endophthalmitis from a contaminated donor button; another following cataract surgery. One developed keratitis in a keratoplasty suture tract; and another patient developed a corneal abscess after being struck with a tree branch. The patient with the contaminated donor button developed overwhelming endophthalmitis resulting in no light perception vision, severe pain, and evisceration. The postoperative cataract patient developed a purulent endophthalmitis and is still hypotonus with light perception vision. The second keratitis patient developed a significant suture abscess with marked stromal loss but eventually healed. The traumatic keratitis patient developed a large ulcer with hypopyon and descemetocele but was lost to follow-up. CONCLUSIONS: This is the first report of a series of BHS-G ocular infections. The ocular infections were characterized by rapid onset, extreme inflammation, and--despite in vitro antibiotic sensitivity--a poor or sluggish response to antibiotic therapy.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
8/78. stenotrophomonas maltophilia endophthalmitis after intraocular lens implantation.BACKGROUND: stenotrophomonas maltophilia is an opportunistic, gram-negative bacillus. endophthalmitis induced by S. maltophilia has been described in only two cases after intraocular lens implantation. We report S. maltophilia endophthalmitis in two patients with diabetes mellitus after intraocular lens implantation and compare the characteristics of the S. maltophilia-induced endophthalmitis with two previous cases. methods: A 68-year-old woman and a 74-year-old man with diabetes mellitus developed S. maltophilia endophthalmitis within 5 days of intraocular lens implantation. We performed intraocular lens removal and vitrectomy, which resolved the inflammation. No recurrences were found. RESULTS: Cultures grew S. maltophilia in both cases, and one of the organisms was multi-resistant. The final visual acuity was counting fingers and 0.3. The first case revealed a tractional retinal detachment during vitrectomy. CONCLUSIONS: S. maltophilia is a potential opportunistic intraocular pathogen, and the incidence of multiresistant S. maltophilia is increasing. S. maltophilia causes acute endophthalmitis, and its prognosis may not be poor unless the eye has a history of serious disease before the cataract surgery. The combined procedure of intraocular lens removal and vitrectomy was useful in resolving the inflammation and preventing recurrences.- - - - - - - - - - ranking = 2keywords = inflammation (Clic here for more details about this article) |
9/78. Epidemic bacillus endophthalmitis after cataract surgery II: chronic and recurrent presentation and outcome.OBJECTIVE: To report the clinical outcome of chronic bacillus endophthalmitis after cataract surgery. DESIGN: Retrospective, noncomparative case series. PARTICIPANTS: Five eyes of five patients with late-onset or recurrent inflammation after exposure to bacteria-contaminated viscoelastic material were studied. INTERVENTION: Repeated vitrectomies, wide excision of the remnant posterior capsule, and intravitreal injections of antibiotics in five patients. Eventual explantation of the intraocular lens in four patients. MAIN OUTCOME MEASURES: Final visual acuities and results of microbiologic studies of aqueous and vitreous specimens as well as pathologic studies using hematoxylin-eosin, Gram, and periodic acid-Schiff (PAS) stain of explanted capsular remnants were obtained. RESULTS: Final visual acuity of 20/40 or better was obtained in three patients. bacillus species were grown from two cases. PAS- and Gram-positive microorganisms were identified in the capsular tissue in three of four patients who had explantation of the intraocular lens. CONCLUSIONS: A chronic form of bacillus endophthalmitis is described for the first time. The clinical outcome is similar to chronic endophthalmitis caused by other organisms.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
10/78. Postoperative mycobacterium chelonae endophthalmitis after extracapsular cataract extraction and posterior chamber intraocular lens implantation.OBJECTIVE: To describe a case of postoperative endophthalmitis caused by mycobacterium chelonae after extracapsular cataract extraction with posterior chamber intraocular lens implantation. DESIGN: Interventional case report. methods: The history and clinical presentation of a 66-year-old female patient, in whom a low-grade delayed-onset endophthalmitis and keratitis developed after extracapsular cataract extraction with posterior chamber intraocular lens implantation, is described. Microbiologic investigations of the scrapings of corneal infiltrate at the cataract incision site, aqueous humor and eviscerated material, and histopathologic study of eviscerated material and an enlarged cervical lymph node were performed. MAIN OUTCOME MEASURES: The clinical, histopathologic, and microbiologic findings in a case of low-grade delayed-onset endophthalmitis. RESULTS: Analysis of the direct smear of both the corneal infiltrate as well as the eviscerated material revealed acid-fast bacilli. M. chelonae was isolated from these specimens. Direct smear and culture of the aqueous humor were negative for bacteria (including mycobacteria) and fungus. Histopathologic examination of the eviscerated material showed a dense infiltration of polymorphonuclear leukocytes in the uveal tissue, extensive necrosis and hemorrhage, and exudates with hemorrhage in the vitreous cavity. Histopathologic examination of the lymph node revealed granulomatous inflammation with caseation necrosis, but did not reveal acid-fast bacilli. CONCLUSIONS: M. chelonae, although infrequent, should be considered an etiologic agent of delayed-onset, postoperative endophthalmitis and early bacterial diagnosis should help in institution of appropriate therapy.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
