Purpose. To investigate if there is a prognostic implication of the presence of cellular debris in the anterior vitreous in patients with Behçet's disease (BD) without any ocular symptoms. Methods. One hundred and twenty eyes of 60 patients with BD were included in the study. The eyes were divided into two groups according to the presence of cellular debris in the anterior vitreous. The first g...

Background. Visceral metastatic spread of ocular melanoma most commonly occurs via hematogenous route to the liver. Lymphatic spread of ocular melanoma into abdominal lymph nodes has not been reported previously. Case Presentation. A 47-year-old man with a history of ocular melanoma presented with a soft tissue mass on CT scan. The mass encased the portal structures of the hepaticoduodenal liga...

PURPOSE To study the in vitro and in vivo interaction of chitosan nanoparticles (CSNPs), a new particulate drug carrier, with epithelial cells on the ocular surface. METHODS CSNPs labeled with fluorescein isothiocyanate-bovine serum albumin were produced by ionotropic gelation. Human conjunctival epithelial cells (IOBA-NHC) were exposed for 15, 30, 60, and 120 minutes to three different CSNP ...

In Portugal, the prevalence of human immunodeficiency virus type 2 (HIV-2) seropositivity is higher than in other European countries or North America. Recent literature data points out a possible difference on the pathogenic potential and on the natural history of HIV-1 and HIV-2, suggesting a lower virulence of HIV-2. Facing these hypothesis and the increasing number of HIV-2 cases, we analyse...

PURPOSE To analyse survival from uveal melanoma diagnosed in England and Wales between 1986-1999 and followed up to 2001. METHODS Data from the National Cancer Registry at the Office for National Statistics were analysed. The data were compiled from population-based cancer registries covering all of England and Wales for all adults (aged 15-99) diagnosed with primary ocular malignancy, exclud...

In the current study we examine parameters affecting the metastasis of ocular tumors of in vivo derived B16F10 melanoma. In C57BL/6J beige (bg/bg) mice, with low NK activity, metastasis to the lungs was increased and survival time decreased. In C57BL/6J normal (+/+) mice treatment with PK136, a highly specific monoclonal anti-NK antibody (Ab), caused a depletion of NK cytotoxic activity, as dem...

In this article, we provide an update on incidence rates of ophthalmic non-Hodgkin's lymphoma (NHL), in the context of other NHL, in the USA. We also provide population-based estimates of incidence and survival for ocular adnexal NHL, the most common form of ophthalmic NHL, for which descriptive patterns have not been previously reported. Ophthalmic and ocular adnexal NHL have unique incidence ...

Avian ophthalmology Free ranging birds are highly dependent on accurate vision in order to capture prey and forage, to avoid predators, and to find suitable perches and shelter. Perfect, or near-perfect, ocular health is imperative to survival for most free living avian species. While perfect vision is less vital for the captive companion parrot, it is nevertheless important to recognize and tr...

Purpose To spatially and temporally define ocular motor nerve development in the presence and absence of extraocular muscles (EOMs). Methods Myf5cre mice, which in the homozygous state lack EOMs, were crossed to an IslMN:GFP reporter line to fluorescently label motor neuron cell bodies and axons. Embryonic day (E) 11.5 to E15.5 wild-type and Myf5cre/cre:IslMN:GFP whole mount embryos and disse...

BACKGROUND Reliable population-based incidence and survival data on extracutaneous melanoma (ECM) are sparse. METHODS Incidence data (1989-2006) from the Netherlands Cancer Registry were combined with vital status on January 1, 2008. Age-adjusted annual incidence rates were calculated by direct standardization, and the estimated annual percentage change was estimated to detect changing trends...
