Visual Acuity Thresholds in Amblyopes.
THE use of the visuscope in an amblyopic eye helps to determine the part of the retina used during uniocular fixation. However, it is also important to know from a clinical standpoint whether the fovea is inhibited through a peripheral or a central mechanism, and whether in a particular case, the resolving power of the rods or the cones is affected. Various authors have studied the behaviour of...
متن کاملScreening for Significant Refractive Error Using a Combination of Distance Visual Acuity and Near Visual Acuity
PURPOSE To explore the effectiveness of using a series of tests combining near visual acuity (NVA) and distance visual acuity (DVA) for large-scale screenings for significant refractive error (SRE) in primary school children. METHOD Each participant underwent DVA, NVA and cycloplegic autorefraction measurements. SREs, including high myopia, high hyperopia and high astigmatism were analyzed. C...
متن کاملDistance and near visual acuity, contrast sensitivity, and visual fields of 10-year-old children.
OBJECTIVE To measure monocular distance visual acuity, near visual acuity, contrast sensitivity, and visual field extent in full-term, 10-year-old children tested according to the protocol used to test 10-year-old preterm children in the Cryotherapy for Retinopathy of Prematurity study. SUBJECTS AND METHODS Subjects were 106 healthy, full-term children, 9.8 to 10.9 years of age, who had no oc...
متن کاملCorrelation between Visual Acuity and Optical Coherence Tomography-Measured Retinal Thickness in Diabetic Macular Edema
Background and Objective: Diabetic macular edema (DME) is one of the common complications of diabetes which significantly accounts for preventable visual impairment and blindness. Central macular thickness (CMT) is a feature found in DME patients. This study aims to determine the relationship between optical coherence tomography (OCT)-measured CMT and visual acuity (VA) in patients with DME bef...
متن کاملHow to measure distance visual acuity
Procedure • Ensure good natural light or illumination on the chart. It is important to ensure that the person has the best possible chance of seeing and reading the test chart as treatment decisions are made based on the results of VA testing. • If the test is done outdoors, the chart should be in bright light and the patient in the shade, with enough light to illuminate the patient’s face duri...
