White-to-white corneal diameter distribution in an adult population
PURPOSE To determine the normal distribution of corneal diameter in a 40- to 64-year-old population and its association with other biometric components. METHODS In a cross-sectional population-based study, subjects were selected through multistage cluster sampling from the 40- to 64-year-old citizens of Shahroud in northern Iran. After obtaining informed consents, optometry tests including re...
متن کاملWhite-to-white corneal diameter: normal values in healthy Iranian population obtained with the Orbscan II.
AIM To determine the normative values of white-to-white corneal diameter with Orbscan II Topography System and to compare right and left eyes data in the normal young population. METHODS A total of 1001 healthy participants aged 18-45y participated in this observational cross-sectional study. The study population consisted of 616 female and 385 male subjects. The corneal diameter was measured...
متن کاملHorizontal Corneal White to White Diameter Measurements Using Calipers and IOLMaster
Purpose: To determine if the mean horizontal white-towhite (WTW) corneal diameter, measured intraoperatively with calipers, of a population of cataract surgery patients differs from the currently accepted normal WTW range of greater than 11.0 and less than 13.0 mm. In addition, we compared manual caliper measurements with those with IOLMaster. Setting: Cincinnati Eye Institute, Cincinnati OH. D...
متن کاملWhite matter microstructure from nonparametric axon diameter distribution mapping
We report the development of a double diffusion encoding (DDE) MRI method to estimate and map the axon diameter distribution (ADD) within an imaging volume. A variety of biological processes, ranging from development to disease and trauma, may lead to changes in the ADD in the central and peripheral nervous systems. Unlike previously proposed methods, this ADD experimental design and estimation...
متن کاملWhite Matter Plasticity in the Adult Brain
The study of brain plasticity has tended to focus on the synapse, where well-described activity-dependent mechanisms are known to play a key role in learning and memory. However, it is becoming increasingly clear that plasticity occurs beyond the synapse. This review focuses on the emerging concept of white matter plasticity. For example, there is growing evidence, both from animal studies and ...
