Development of an Accommodation-Dependent Eye Model and Studying the Effects of Accommodation on Electron and Proton Dose Conversion Coefficients
Introduction International Commission on Radiological Protection (ICRP) has provided a comprehensive discussion on threshold dose for radiation-induced cataract in ICRP publication 116. Accordingly, various parts of the eye lens have different radio-sensitivities. Recently, some studies have been performed to develop a realistic eye model with the aim of providing accurate estimation of fluence...
متن کاملAccommodation and Stereoacuity
Stereoacuity and resolution acuity were measured (1) through apertures set at various distances from S and (2) through plus lenses producing an accommodative error for the target equal to that produced by the presence of the apertures. Stereoacuity was degraded by the apertures but not by the lenses, whereas resolution acuity was degraded by the lenses but not by the apertures. Although stereoa...
متن کاملAccommodation and presbyopia.
Accommodation is a dioptric change in power of the eye that occurs to allow near objects to be focused on the retina. The ability to accommodate is lost with increasing age in humans and monkeys. This phenomenon, called presbyopia, is the most common human ocular affliction, and its pathophysiology remains uncertain. The progressive loss of human accommodative amplitude begins early in life and...
