The purpose of this study is to compare visual acuity and redness of eyes between a new contact lens and an already marketed contact lens.
The purpose of this study is to compare the clinical performance of three silicone hydrogel contact lenses over a 2 week period.
This study will assess the ophthalmic compatibility of three different silicone hydrogel lenses worn on an overnight basis for six nights by adapted daily soft contact lens wearers.
Study of low dose atropine in preventing the onset and progression of myopia in high risk children with pre-myopia or low-myopia.
We have identified focussing problems related to myopia getting worse. Our trial uses optical and orthoptic interventions that correct the focussing problems to see if this retards myopia ...
During the past 30 years, the prevalence rate of myopia has been increased dramatically. Myopia has become one of the leading causes of vision loss in some countries, whereas the mechanism of the main...
The burden associated with the rising prevalence of myopia and high myopia, and the associated vision impairment and sight-threatening complications, has triggered the need to evaluate strategies to c...
The purpose of this study was to determine the prevalence of myopia in a population of children in Sweden. Retrospective analysis of children in a region in Sweden referred to eye care from the nation...
In the nineteenth century, the prevalence of myopia began to rise, and Cohn stressed the role of education. Later, based on twin studies, Sorsby argued that refraction was almost totally genetically d...
Experimental myopia in animal models suggests that bright light can influence refractive error and prevent myopia. Additionally, animal research indicates activation of rod pathways and circadian rhyt...
Excessive axial myopia associated with complications (especially posterior staphyloma and CHOROIDAL NEOVASCULARIZATION) that can lead to BLINDNESS.
A projective test used to evaluate a broad range of personality variables including pathology of thought and perception. The subject's responses to inkblot prints are scored along with subjective interpretation by the test administrator.
A test to determine the lowest sound intensity level at which fifty percent or more of the spondaic test words (words of two syllables having equal stress) are repeated correctly.
Tests of accuracy in pronouncing speech sounds, e.g., Iowa Pressure Articulation Test, Deep Test of Articulation, Templin-Darley Tests of Articulation, Goldman-Fristoe Test of Articulation, Screening Speech Articulation Test, Arizona Articulation Proficiency Scale.
Method of measuring the bactericidal activity contained in a patient's serum as a result of antimicrobial therapy. It is used to monitor the therapy in BACTERIAL ENDOCARDITIS; OSTEOMYELITIS and other serious bacterial infections. As commonly performed, the test is a variation of the broth dilution test. This test needs to be distinguished from testing of the naturally occurring BLOOD BACTERICIDAL ACTIVITY.
