Summary of "The Repeatability of Values Measured Using the Spot Vision Screener in Healthy Children and Children with Refractive Errors."

To determine the repeatability of refractive values measured using the Spot vision screener in healthy children and children with refractive errors. This cross-sectional study included 170 eyes of 85 healthy children (normal group), and 50 eyes of 25 children wearing spectacles for refractive errors (spectacles group). The spherical equivalent value, cylindrical value, and inter-ocular differences in the spherical equivalent values were analyzed. The repeatability of the refractive values measured using the Spot vision screener was determined using intra-class correlation coefficients (ICCs) and 95% limits of agreement. In the normal group, ICC values for the spherical equivalent value, cylindrical value, and amount of anisometropia were 0.77, 0.80, and 0.64, respectively. In the spectacles group with spectacles they were 0.89, 0.67, and 0.78, respectively. In the spectacles group without spectacles they were 0.96, 0.78, and 0.97, respectively. The 95% limits of agreement between consecutive measurements for the spherical equivalent value, cylindrical value, and amount of anisometropia were within ±1.00 D in the normal group and the spectacles group with spectacles, and over ±1.00 D in the spectacles group without spectacles. The Spot vision screener can ensure better than moderate repeatability with and without spectacles.

Medical and Biotech [MESH] Definitions

Vision considered to be inferior to normal vision as represented by accepted standards of acuity, field of vision, or motility. Low vision generally refers to visual disorders that are caused by diseases that cannot be corrected by refraction (e.g., MACULAR DEGENERATION; RETINITIS PIGMENTOSA; DIABETIC RETINOPATHY, etc.).

A physical property showing different values in relation to the direction in or along which the measurement is made. The physical property may be with regard to thermal or electric conductivity or light refraction. In crystallography, it describes crystals whose index of refraction varies with the direction of the incident light. It is also called acolotropy and colotropy. The opposite of anisotropy is isotropy wherein the same values characterize the object when measured along axes in all directions.

The complete summaries of the frequencies of the values or categories of a measurement made on a group of items, a population, or other collection of data. The distribution tells either how many or what proportion of the group was found to have each value (or each range of values) out of all the possible values that the quantitative measure can have.

Tests to experimentally measure the tumor-producing/cancer cell-producing potency of an agent by administering the agent (e.g., benzanthracenes) and observing the quantity of tumors or the cell transformation developed over a given period of time. The carcinogenicity value is usually measured as milligrams of agent administered per tumor developed. Though this test differs from the DNA-repair and bacterial microsome MUTAGENICITY TESTS, researchers often attempt to correlate the finding of carcinogenicity values and mutagenicity values.

Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.
