Horizontal cells are retinal interneurons that establish inhibitory feedback loops within the outer plexiform layer of the primary visual pathway. Most mammalian retinas contain two types of horizontal cells. A-type horizontal cells have neuritic branches that contact cone photoreceptors exclusively, while the B-type horizontal cells have dendritic branches… (More)
PURPOSE To study the morphologic and neurochemical development of the rabbit retina in explant culture. METHODS Explants of retina from newborn rabbits were cultured in defined medium in the absence of serum or soluble growth factors. The morphology of the explant and the neurochemical development of the GABAergic system were examined by light microscopy,… (More)
PURPOSE To investigate conditions promoting the differentiation of cultured human retinal pigment epithelial (RPE) cells and assess the differentiation potential of telomerase-immortalized RPE cells. METHODS Serially passaged RPE 340 (parental) cells have limited replicative ability and senesce after 50 to 60 population doublings (PD)s. RPE 340 cells… (More)
Registration includes two continental breakfasts, AM and PM coffee breaks each day, two lunches and course materials..
Age-related macular degeneration (AMD) is the leading cause of irreversible blindness in people over 60 years of age in the US and many other developed countries. Increasingly sophisticated methods for the diagnosis and treatment of macular degeneration are not effective for the majority of patients in whom late stage disease is present at the time of… (More)
The use of tissue- and cell-based methods in developing drugs for retinal diseases is inefficient. Consequently, many aspects of ocular drug therapy for retinal diseases are poorly understood. Biomarkers as prognostic indicators of change are needed to optimize the use of drugs. VEGF is considered an important target of drug therapy and VEGF levels in… (More)
PURPOSE The use of a dual prostaglandin E3 (EP3) and prostaglandin F (FP) receptor agonist is a novel approach for the reduction of intraocular pressure (IOP) in open angle glaucoma and ocular hypertension and, as such, ONO-9054 may have benefits over existing therapies. The objectives of this phase I study were to assess the safety, tolerability, systemic… (More)
BACKGROUND/AIMS The novel prostaglandin E (EP) 3 and prostaglandin F (FP) receptor agonist ONO-9054 is effective in lowering intraocular pressure (IOP) in patients with ocular hypertension and open-angle glaucoma when administered once daily. This study compares the effects of morning (AM) versus evening (PM) dosing of ONO-9054 on tolerability and IOP… (More)
