BACKGROUND To examine the utility of DNA microarray analysis for identifying causative microorganisms in endophthalmitis. METHODS Thirteen samples of vitreous fluid (VF) were obtained from 13 patients during vitrectomy. Vitreous fluids from three patients with suspected endophthalmitis and ten controls without infection were subjected to testing for the presence of bacteria and fungi in cultu...

BACKGROUND/AIMS To study the intravitreal antibiotic concentrations and the efficacy of an intravitreal dosing regimen to treat patients with postoperative bacterial endophthalmitis. This regimen, based on pharmacokinetic/pharmacodynamic considerations, relies on a repeat antibiotic injection of a lower dose than is generally used. METHODS In consecutive patients with suspected postoperative ...

Vitreous floaters are one of the most common complain ophthalmological patients. The aetiology includes pathological process (vitreous haemorrhages, injuries, diabetics or uveitis) and also natural age-related changes in vitreous body. Diagnosis treatment depends on severity symptoms. Process posterior detachment requires particularly careful monitoring, because potential complications such as ...

OBJECTIVES Recent reports of high endophthalmitis rates after intravitreal triamcinolone acetonide injection have raised concerns about the safety of this treatment. We sought to evaluate the effect of intravitreal triamcinolone injection on (1) the susceptibility to experimental bacterial endophthalmitis and (2) the subsequent therapeutic response to antibiotic treatment. DESIGN For the susc...

PURPOSE Vascular endothelial growth factor (VEGF) concentrations in various regions of the vitreous were examined in patients with diabetic macular edema (DME) to explore the possibility of a concentration gradient in the vitreous. METHODS Vitreous samples were collected during vitrectomy from 71 eyes of 71 patients with DME and without posterior vitreous detachment who had not undergone panr...

A patient presented with acute-onset, postoperative endophthalmitis and visual acuity of light perception. Because of a time delay in arranging a pars plana vitrectomy (PPV), the patient was treated with a prompt vitreous tap for culture an injection of vancomycin and ceftazidime. Four hours later, the PPV was performed and additional antibiotics were injected. The cultures from both the initia...

BACKGROUND We report a case of bacterial endophthalmitis caused by an intraocular cilium in a patient without any history of trauma or ocular surgery. FINDINGS A 32-year-old Caucasian male showed symptoms of orbital myositis and scleritis, with no intraocular inflammation in the right eye. The patient had been treated with infliximab for Crohn's disease. Three weeks after initiation of oral p...

Although there have been a few reported cases of Enterococcal endophthalmitis, this is an unusual case of endophthalmitis complicated with corneal ulcer caused by Enterococcus faecalis. A 67-year-old male patient with diabetes mellitus underwent secondary intraocular lens implantation. Post-operative recovery was uneventful until a wound rupture was noted 3 weeks after the operation. On day 12 ...

PURPOSE Müller cells are consistently identified in diabetic fibrocontractive ocular tissues and, in response to insulin-like growth factor I, generate tractional forces of the type that cause retinal detachment. Recent studies suggest that diabetes-associated increases in vitreous insulin-like growth factor activity cannot be attributed to simple increases in concentration alone, suggesting th...
