Persons with age-related maculopathy risk genotypes and clinically normal eyes have reduced mesopic vision.
PURPOSE To determine whether participants with normal visual acuity, no ophthalmoscopically signs of age-related maculopathy (ARM) in both eyes, and who are carriers of the CFH, LOC387715, and HRTA1 high-risk genotypes (gene-positive) have impaired rod- and cone-mediated mesopic visual function compared with persons who do not carry the risk genotypes (gene-negative). METHODS Fifty-three Cauc...
متن کاملProgression of age related maculopathy in phakic versus pseudophakic eyes.
Age-related maculopathy (ARM) is one of the leading causes of central visual acuity loss in older western population. Many factors are responsible for the fast development of ARM. One of this is significant increases of optical radiations through artificial lens after removal of the catarctous lens. The aim of this study was to compare progression of ARM in phakic and pseudophakic patients and ...
متن کاملRisk Factors for Age-Related Maculopathy
Age-related maculopathy (ARM) is the leading cause of blindness in the elderly. Although beneficial therapeutic strategies have recently begun to emerge, much remains unclear regarding the etiopathogenesis of this disorder. Epidemiologic studies have enhanced our understanding of ARM, but the data, often conflicting, has led to difficulties with drawing firm conclusions with respect to risk for...
متن کاملAssessment of age-related maculopathy using subjective vision tests.
This paper reviews non-standard, clinical vision tests that may be used to detect the earliest visual loss in age-related maculopathy (ARM), before fundus changes are detected. We recommend a clinical test battery for all patients aged 60 years and older, comprising low luminance/low contrast (SKILL) VA or low contrast VA, desaturated D-15 colour vision assessment, flicker perimetry, glare reco...
متن کاملImpaired mesopic visual acuity in eyes with early age-related macular degeneration.
PURPOSE To determine photopic and mesopic distance high-contrast visual acuity (HC-VA) and low-contrast visual acuity (LC-VA) in eyes with early age-related macular degeneration (AMD). METHODS Measurements were made in 22 subjects with early AMD and 28 healthy control subjects. Inclusion criteria included a photopic HC-VA of 20/25 or better. Distance VA was measured using HC (96%) and LC (10%...
