BACKGROUND/AIMS Behçet's disease (BD) is a systemic inflammatory vasculitis of young adults with unknown aetiology, characterised by endothelial dysfunction and occlusion in both deep venous and retinal circulation. Ocular involvement occurs in 70% of cases and is characterised by periphlebitis, periarteritis, vascular occlusion, and thrombosis leading to blindness despite vigorous treatment. E...

Bacterial isolation, identification and antimicrobial susceptibility tests were carried out in ocular material collected with swab and polimethylmethacrylate (PMMA) or silicone intraocular lenses (IOL) from forty six patients submitted to cataract surgery. Seventy six isolates and seven different microorganisms were identified. Coagulase-negative staphylococci (CNS) were the predominant microor...

INTRODUCTION Conjunctival swab PCR was evaluated as a tool to diagnose visceral leishmaniasis in dogs. METHODS Conjunctival swab PCR was compared to indirect immunofluorescence antibody test and blood PCR. RESULTS Indirect immunofluorescence was significantly correlated with conjunctival swab PCR (p < 0.05), but not with blood PCR (p > 0.05). In addition, conjunctival swab PCR was significa...

background and aims: toxoplasmosis is a parasitic disease which may cause some laboratory symptoms in infected individuals. one of the main ways of transmition this organism is placenta to fetus pathway. if this transmission occurs in the 3th month of pregnancy, the abortion, central nerve system and ocular disorder will happen. because of this issue, the precise technique for detection of toxo...

PURPOSE The purpose of this study is to report a case of Providencia stuartii conjunctivitis. METHODS This study is a retrospective chart review of a patient with persistent conjunctivitis. RESULTS We report the first case of P. stuartii conjunctivitis. Our patient was an elderly man living in a nursing home who was likely immunocompromised from longstanding diabetes mellitus. A conjunctiva...

Ocular lesions are a common manifestation of toxoplasmosis in cats. In this survey, 10 healthy Syrianmice were infected through intraperitoneal inoculation of bradyzoites of Toxoplasma gondii (Tehran strain).Mice were killed 30 days after inoculation and the suspension of their brains was prepared, after confirmationof the infection. Seven kittens were fed with the infected mice brain suspensio...

The role of nitric oxide (NO) in the ocular surface remains unknown. We investigated the conditions leading to an increase of NO generation in tear and the main sources of NO in ocular surface tissue. We evaluated the dual action (cell survival or cell death) of NO depending on its amount. We measured the concentration of nitrite plus nitrate in the tears of ocular surface diseases and examined...

Twenty-four matched pairs of isolates of Pasteurella haemolytica and three matched pairs of isolates of Pasteurella multocida were isolated by using a nasal swab and a transtracheal swab from individual calves with clinical signs of bovine respiratory disease. The identity of each matched pair was confirmed biochemically and serologically. The similarity of the isolates obtained from a nasal sw...

purpose: controversy has recently risen about the presence of compensatory ocular countertorsion (coct) after head tilt. this study was performed to define the functional range of this phenomenon. methods: cycloplegic autorefraction was performed on 80 eyes with regular astigmatism 2d. objective autorefraction was performed in normal position, right and left head tilt positions of 5º, 10º, 15º,...
