1/203. 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 = visual (Clic here for more details about this article) |
2/203. listeria monocytogenes endophthalmitis with a black hypopyon.A 68-year-old woman had a marked decrease in visual acuity, increased intraocular pressure, and acute iridocyclitis. She developed a pigmented hypopyon simulating an occult intraocular melanoma. Two anterior chamber paracenteses showed growth of listeria monocytogenes. The patient received systemic intravenous penicillin, topical fortified gentamicin sulfate drops, and intraocular injections of cephaloridine. On discharge from the hospital after a two-week stay, visual acuity had improved and intraocular pressure had decreased.- - - - - - - - - - ranking = 2keywords = visual (Clic here for more details about this article) |
3/203. Post-traumatic endophthalmitis: causative organisms and visual outcome.PURPOSE: Post-traumatic endophthalmitis makes up a distinct subset of intraocular infections. The purpose of the present study was to identify the causative organisms and record the visual outcome after infectious endophthalmitis in eyes with penetrating trauma. methods: We reviewed 18 consecutive cases of culture-positive endophthalmitis that developed after penetrating ocular trauma. All cases were treated with pars plana vitrectomy and intravenous and intraocular antibiotics. RESULTS: The 15 males and 3 females ranged in age from 4 to 43 years (mean 25.1 /- 11 years). Nine (50%) had intraocular foreign bodies. A single species was isolated in 16 cases, and multiple organisms in two. staphylococcus epidermidis and gram-negative organisms were the most frequent and were cultured either alone or in association with other organisms in respectively five (27.7%) and four cases (22.2%). clostridium perfringens was isolated in three cases (16.6%). bacillus was not found as a cause of endophthalmitis. Final visual acuity was better than 20/400 in eight cases (44%). In five cases (27.7%), the eye was saved but visual acuity was counting fingers. Two eyes (11%) had no light perception. The remaining three eyes (16.6%) were enucleated or eviscerated. clostridium perfringens was isolated from two eyes and aspergillus niger from one. Postoperative retinal detachment developed in four eyes, which were successfully operated. CONCLUSIONS: Organisms isolated in this series were similar to those in previous reports of post-traumatic endophthalmitis from other parts of the world, except that the frequency of clostridium perfringens isolation was high and no bacillus species were cultured. In view of its devastating outcome, post-traumatic endophthalmitis must be treated promptly with vitrectomy and intravitreal antibiotics.- - - - - - - - - - ranking = 7keywords = visual (Clic here for more details about this article) |
4/203. listeria monocytogenes-induced endogenous endophthalmitis in an otherwise healthy individual: rapid PCR-diagnosis as the basis for effective treatment.PURPOSE: listeria monocytogenes is a rare cause of endogenous endophthalmitis. To date 15 cases have been published in the literature. All eyes showed similar clinical features and profound visual loss mainly due to delayed diagnosis. methods: An additional case of an otherwise healthy 73 year-old male, who was referred to our hospital because of acute iridocyclitis with secondary glaucoma, is reported. Within a few days the severity of the intraocular infection increased dramatically, resulting in the clinical picture of acute endophthalmitis. RESULTS: In contrast to most published cases, early identification of the causative pathogen in the aqueous humor after anterior chamber puncture using polymerase chain reaction (PCR) and the initiation of a specific, systemic antibiotic medication, resulted in-complete recovery of visual acuity. CONCLUSIONS: PCR is very useful for the identification of the pathogen in intraocular infections.- - - - - - - - - - ranking = 2keywords = visual (Clic here for more details about this article) |
5/203. Bacterial endophthalmitis after suture removal.We present 3 cases of endophthalmitis following suture removal after cataract surgery. In all cases, prophylactic antibiotics had been used. Treatment included vitreous tap and intravitreal antibiotic injection, with only 1 of the 3 patients regaining good visual acuity. Because povidone-iodine 5% is more effective at decreasing conjunctival bacterial counts than topical antibiotics, we recommend this method of conjunctival preparation before suture removal.- - - - - - - - - - ranking = 1keywords = visual (Clic here for more details about this article) |
6/203. 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.- - - - - - - - - - ranking = 0.52098965677012keywords = sensitivity (Clic here for more details about this article) |
7/203. serratia marcescens renal abscess with endophthalmitis: a case report.A renal abscess, caused by serratia marcescens with endophthalmitis in a 68-year-old diabetic female, is described. endophthalmitis presented with visual loss, conjunctiva injection and lid edema with eye pain. Right costovertebral knocking pain was also noted. Sonography and computed tomography of abdomen showed a 4 cm hypoechoic lesion in the middle portion of the right kidney with marginal enhancement after contrast media injection. Percutaneous abscess drain was performed. Pus culture from the drain tube revealed S. marcescens, yet, vitreous cultures yielded no growth, which was ascribed to previous antibiotics use. Although vitrectomy, fortified eye drops, intravitreal and systemic intravenous antibiotics were administered, the visual function was still lost. To our knowledge, this is the first reported case of S. marcescens renal abscess complicated with endophthalmitis.- - - - - - - - - - ranking = 2keywords = visual (Clic here for more details about this article) |
8/203. endophthalmitis from mycobacterium bovis-bacille Calmette-Guerin after intravesicular bacille Calmette-Guerin injections for bladder carcinoma.PURPOSE: To present clinical and histologic findings of intraocular infection with mycobacterium bovis-bacille Calmette-Guerin after intravesicular bacille Calmette-Guerin injections for treatment of bladder carcinoma. methods: A 77-year-old man was initially seen with visual acuity of 20/200, focal retinitis, vasculitis, and progressive vitreous opacity in the right eye and visual acuity of light perception, intraocular inflammation, and a dense cataract in the left eye 14 months after intravesicular injection of live bacille Calmette-Guerin organisms. RESULTS: Vitreous cultures in the right eye demonstrated growth of bacille Calmette-Guerin organisms. Bilateral loss of light perception occurred despite systemic antimy-cobacterial therapy. Histopathologic examination demonstrated nongranulomatous inflammation and acid-fast bacilli in both eyes. CONCLUSION: Delayed endogenous endophthalmitis may develop after intravesicular bacille Calmette-Guerin injection that may not respond to systemic agents. Intravitreal therapy may be indicated.- - - - - - - - - - ranking = 2keywords = visual (Clic here for more details about this article) |
9/203. Caterpillar setae in the deep cornea and anterior chamber.PURPOSE:To report a case of caterpillar setae embedded in the deep cornea and anterior chamber. methods: A 26-year-old man was struck in his right eye by a caterpillar (Dendrolimus punctatus walker). Severe conjunctival injection, chemosis, and erosion of the cornea developed immediately. Numerous setae fragments were found to be embedded into the palpebral conjunctiva and deep cornea, extending into the anterior chamber near the anterior iris surface. RESULTS: After partial removal of the setae under a microscope, the inflammation subsided and visual acuity improved to RE: 20/20. CONCLUSION: Caterpillar setae are sharp enough to penetrate the cornea and extend into the anterior chamber.- - - - - - - - - - ranking = 1keywords = visual (Clic here for more details about this article) |
10/203. oxacillin-resistant staphylococcus aureus endophthalmitis after ganciclovir intraocular implant.PURPOSE: To describe a patient who developed oxacillin-resistant staphylococcus aureus endophthalmitis after insertion of a ganciclovir intraocular implant. METHOD: Case report. RESULTS: A 42-year-old man with acquired immunodeficiency syndrome (AIDS) and a history of cytomegalovirus retinitis was admitted with right-sided eye pain and decreased visual acuity 10 days after receiving a second ganciclovir intraocular implant in the right eye. A therapeutic vitrectomy, right eye, was performed on the day of admission. A vitreal tap produced frank pus and white, fluffy debris. Cultures of the vitreal fluid grew oxacillin-resistant S aureus, sensitive only to vancomycin, rifampin, and trimethoprim/sulfamethoxazole. The patient was successfully treated with removal of both ganciclovir implants in the right eye and a 4-week course of vancomycin and rifampin. However, the infection left the patient blind in the infected eye. CONCLUSION: Bacterial endophthalmitis is an infrequent but serious complication of the ganciclovir intraocular implant.- - - - - - - - - - ranking = 1keywords = visual (Clic here for more details about this article) |
