Medical and Biotech [MESH] Definitions
Infections with POLYOMAVIRUS, which are often cultured from the urine of kidney transplant patients. Excretion of BK VIRUS is associated with ureteral strictures and CYSTITIS, and that of JC VIRUS with progressive multifocal leukoencephalopathy (LEUKOENCEPHALOPATHY, PROGRESSIVE MULTIFOCAL).
The normal decreasing elasticity of the crystalline lens that leads to loss of accommodation.
Slow Virus Diseases
Diseases of viral origin, characterized by incubation periods of months to years, insidious onset of clinical manifestations, and protracted clinical course. Though the disease process is protracted, viral multiplication may not be unusually slow. Conventional viruses produce slow virus diseases such as SUBACUTE SCLEROSING PANENCEPHALITIS, progressive multifocal leukoencephalopathy (LEUKOENCEPHALOPATHY, PROGRESSIVE MULTIFOCAL), and AIDS. Diseases produced by unconventional agents were originally considered part of this group. They are now called PRION DISEASES.
Complete severing of the CORPUS CALLOSUM. In humans it is usually performed to treat medically intractable, multifocal EPILEPSY. EXPERIMENTAL ANIMAL MODELS of split brain preparations are used in research.
A fluid-filled closed cavity or sac that is lined by an EPITHELIUM and found in the BREAST. It may appear as a single large cyst in one breast, multifocal, or bilateral in FIBROCYSTIC BREAST DISEASE.
The purpose of this small-scale trial is to compare the performance of the lotrafilcon B multifocal lens system to ACUVUE OASYS for PRESBYOPIA contact lens system.
The objective of the study is to assess the visual performance and the success rate of AIR OPTIX Aqua multifocal lenses compared with a contact lens and reading glasses combination. The h...
The Presbyopia Algorithm subject to this study has been specifically developed to prospectively generate a treatment file for the Technolas 217z100 laser that will provide Presbyopia corre...
Chemotherapy drugs, used in cancer treatments, may change the timing of a vision condition known as presbyopia. Presbyopia is the inability to focus the eye on close objects, by a process...
The purpose of this study is to evaluate the effect of a multi-focal contact lens on symptomatic patients.
PURPOSE: To investigate the outcomes of simultaneous correction of presbyopia and ametropia by a bi-aspheric cornea modulation technique, based on the creation of a central area hyperpositive for near...
To conduct a feasibility study of the safety and efficacy of a corneal contouring inlay as a treatment for emmetropic presbyopia.
The surgical correction of presbyopia is gaining more and more popularity in the field of refractive surgery. Besides intraocular treatment with multifocal or accommodative intraocular lenses more and...
BACKGROUND: The aim of this study was to examine the mesopic contrast sensitivity (CS) and glare sensitivity following intrastromal femtosecond laser correction of presbyopia (INTRACOR). PATIENTS AND...
PURPOSE: To examine the relative changes in modulus of nine soft contact lens materials when exposed to three lens care solutions. METHOD: Measurements of elastic modulus were made using an Instron 33...
