1/83. 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.- - - - - - - - - - ranking = 1keywords = ocular (Clic here for more details about this article) |
2/83. Cyanoacrylate tissue adhesive augmented tenoplasty: a new surgical procedure for bilateral severe chemical eye burns.PURPOSE: To report on cyanoacrylate tissue adhesive augmented tenoplasty, a new surgical procedure for bilateral severe chemical eye injuries. methods: A 26-year-old man presented with bilateral severe (grade IV) chemical burns involving the eye, periorbital tissues, face, and neck. Despite adequate medical therapy, corneal, limbal, and scleral ulceration progressed in both eyes. Secondary Pseudomonas keratitis necessitated therapeutic penetrating keratoplasty in the right eye. Tenoplasty and glued-on rigid gas permeable contact lens were unsuccessful to arrest progression of corneolimboscleral ulceration in the left eye. We applied n-butyl cyanoacrylate tissue adhesive directly on the ulcerating corneal, limbal, and scleral surface to augment tenoplasty. RESULTS: The left ocular surface healed with resultant massive fibrous tissue proliferation and symblepharon on the nasal side. Ocular surface rehabilitation resulted in a vascularized leukomatous corneal opacity with upper temporal clear cornea. The patient achieved visual acuity of 6/36 in the left eye. CONCLUSION: We suggest that cyanoacrylate tissue adhesive-augmented tenoplasty can be undertaken to preserve ocular integrity and retain visual potential in a severe chemical eye injury.- - - - - - - - - - ranking = 3278.4372747628keywords = keratitis, ocular (Clic here for more details about this article) |
3/83. Bilateral Pseudomonas corneal ulcer in a disposable contact lens wearer.PURPOSE: To describe a case of bilateral corneal ulcers caused by Pseudomonas in a disposable soft contact lens wearer. This case study discusses the role of patient examination, contact lens care instruction, and adequate patient supervision in reducing the risk of serious potential complications. methods AND RESULTS: A 17 year old student who had been using disposable soft contact lenses on an extended wear basis for 6 months presented complaining of pain in the left eye. When he was examined, a corneal ulcer with surrounding infiltrate was observed in the superior middle periphery of the left eye. Samples were collected for culture, and treatment with fortified cefalotin and gentamicin was started. After 8 hours the patient returned, now complaining of pain in the right eye. Examination of the right eye revealed a diffused keratitis with a mucopurulent discharge. A culture was taken, and the same treatment was instituted. The laboratory tests revealed Pseudomonas in both eyes. The bilateral corneal ulcers responded to therapy after 1 week of treatment. CONCLUSIONS: We discuss the factors involved in the occurrence of infectious keratitis in contact lens wearers, and stress that even disposable contact lens wear can be associated with serious complications. This case also highlights extended wear as one of the main risk factors for complications in disposable soft contact lens wear.- - - - - - - - - - ranking = 6554.8745495256keywords = keratitis (Clic here for more details about this article) |
4/83. Unusual case of acanthamoeba polyphaga and pseudomonas aeruginosa keratitis in a contact lens wearer from Gauteng, south africa.acanthamoeba species can cause a chronic, progressive ulcerative keratitis of the eye which is not responsive to the usual antimicrobial therapy and is frequently mistaken for stromal herpes keratitis. An unusual case of coinfection with acanthamoeba polyphaga and pseudomonas aeruginosa as causes of corneal keratitis in a contact lens wearer from Gauteng, south africa, is reported. These two pathogens have previously been assumed to be selectively exclusive. cysts of the isolated acanthameba tolerated an incubation temperature of 40 degrees C, indicating a pathogenic species. This case highlights the importance of culture methods in the diagnosis of corneal infection and the choice of treatment regimen. The patient's history of careless contact lens-disinfecting habits emphasizes the need to adhere strictly to recommended methods of contact lens care.- - - - - - - - - - ranking = 22943.097161236keywords = keratitis, herpes (Clic here for more details about this article) |
5/83. bacteremia, meningitis, and brain abscesses in a hospitalized infant: complications of pseudomonas aeruginosa conjunctivitis.This report describes a preterm infant hospitalized in a neonatal intensive care unit who developed pseudomonas aeruginosa conjunctivitis associated with bacteremia, meningitis, and multiple brain abscesses. P. aeruginosa conjunctivitis can rapidly progress to an invasive eye infection, such as corneal ulceration or endophthalmitis, leading to poor vision or blindness. Progression of this infection may lead to systemic disease. However, as illustrated in this report, P. aeruginosa conjunctivitis may be associated with the development of systemic complications such as bacteremia and meningitis in the absence of invasive eye disease. P. aeruginosa is a relatively common cause of conjunctivitis in hospitalized preterm and low birth weight infants. Given the severity of the ocular and systemic complications of Pseudomonas conjunctivitis, clinicians are reminded that prompt detection and treatment of neonatal conjunctivitis is critical.- - - - - - - - - - ranking = 0.5keywords = ocular (Clic here for more details about this article) |
6/83. Severe sclerokeratitis due to pseudomonas aeruginosa in noncontact-lens wearers.PURPOSE: To review the clinical presentation, treatment and outcome in four cases of severe anterior segment infection by pseudomonas aeruginosa unrelated to contact lens wear. methods: Four cases presenting over an 18 month period were reviewed. RESULTS: The cases had variable presenting features and outcomes. Complications such as persistent infection, corneal thinning and phthisis bulbi were noted. Possible factors influencing adherence and tissue disruption are discussed. CONCLUSIONS: Suspicion of infection by P. aeruginosa and prompt isolation of the organism is needed early in the course of disease. Intensive and prolonged treatment with parenteral and topical antibiotics combined with judicious use of topical steroid gives the best chance of a favourable outcome.- - - - - - - - - - ranking = 13109.749099051keywords = keratitis (Clic here for more details about this article) |
7/83. Spontaneous corneal perforation and endophthalmitis in pseudomonas aeruginosa infection in a ventilated patient: a case report.We report a case of Pseudomonas keratitis and endophthalmitis after inoculation from the respiratory tract in a mechanically ventilated patient. In these (semi)comatose and more vulnerable patients, colonisation of the upper respiratory tract by Pseudomonas occurs frequently, and this can lead to inoculation of the eyes. Emphasis lies on careful prevention of ocular inoculation and aggressive therapy as soon as keratitis is noticed.- - - - - - - - - - ranking = 6555.3745495256keywords = keratitis, ocular (Clic here for more details about this article) |
8/83. Endogenous pseudomonas aeruginosa endophthalmitis: a case report and literature review.Endogenous endophthalmitis is a vision-threatening condition that results from the hematogenous spread of infection to the eye that originated in a distant primary focus. Although it has long been recognized that bloodborne organisms can infect the eye, endogenous bacterial endophthalmitis is considered a rare entity. We present a unique case of a critically ill patient with a cholangiocarcinoma complicated by ascending cholangitis who developed endogenous pseudomonas aeruginosa endophthalmitis. An awareness of the risk factors predisposing to endogenous endophthalmitis and a high clinical suspicion are necessary to make an early diagnosis in the intensive care unit. Management involves an aggressive combined medical and surgical approach in an effort to prevent ocular morbidity and vision loss.- - - - - - - - - - ranking = 0.5keywords = ocular (Clic here for more details about this article) |
9/83. An unusual case of corneal perforation secondary to Pseudomonas keratitis complicating a patient's surgical/trauma intensive care unit stay.We report a case of corneal perforation secondary to bacterial keratitis caused by pseudomonas aeruginosa in a trauma patient in our intensive care unit. A 43-year-old man was involved in a motorcycle crash and suffered multiple injuries necessitating a prolonged intensive care unit (ICU) stay. Subsequently P. aeruginosa was cultured from his sputum, blood, and open abdomen. He developed a bacterial keratitis in his right eye, which also grew P. aeruginosa. This infection rapidly progressed to corneal perforation requiring a Gunderson conjunctival flap and lateral tarsorrhaphy in addition to aggressive antibiotic treatment. At the time of discharge from the hospital the patient had the return of vision to light only in his right eye. corneal perforation is an unusual event in the ICU. Prevention or early detection of bacterial keratitis with aggressive antibiotic treatment is needed to prevent such complications. Pseudomonas is one of the more virulent organisms that can infect the cornea and early identification is paramount for a good outcome. Management of this complicated case is discussed and the limited amount of literature on nosocomial bacterial keratitis in the ICU is reviewed.- - - - - - - - - - ranking = 26219.498198102keywords = keratitis (Clic here for more details about this article) |
10/83. Pseudomonas corneal ulcer. The causative role of contaminated eye cosmetics.The clinical significance of contaminated ocular cosmetics is illustrated by the case of a 47-year-old woman in whom a Pseudomonas corneal ulcer developed immediately after she sustained minor corneal trauma with a mascara applicator. pseudomonas aeruginosa was cultured from the corneal ulcer and the mascara. In addition to the causative role in acute corneal ulcers, contaminated eye cosmetics contribute to chronic external eye infections. Retail eye cosmetics are typically free of contamination when purchased. The inoculation of the cosmetic occurs during normal use.- - - - - - - - - - ranking = 0.5keywords = ocular (Clic here for more details about this article) |
