Functional Spasm of Accommodation.
FUNCTIONAL spasm of accommodation was described by von Graefe (1856), and there are many case reports in the literature (Duke-Elder, 1949). The condition is sufficiently infrequent to retain a slightly bizarre flavour. The cases which occur sporadically in the out-patient departments of hospitals tend to be dismissed as relatively unimportant, and it is rare to be able to obtain an effective fo...
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
15 صفحه اولChanges in anterior chamber eye during accommodation as assessed using a Dual Scheimpflug system.
PURPOSE To study the changes in anterior chamber depth (ACD), anterior chamber angle (ACA), and pupil diameter (PD) during accommodation. METHODS Eighty eyes of 80 subjects, aged 22 to 40 years, were included. The rotating Dual Scheimpflug and a Placido disc system (Galilei G4, Ziemer Ophthalmic Systems AG, Switzerland) was used to measure the changes in ACD, ACA, and PD during accommodation....
متن کاملAge-Related Changes in Corneal Deformation Dynamics Utilizing Scheimpflug Imaging
PURPOSE To study age-related changes in corneal deformation response to air-puff applanation tonometry. METHODS Fifty healthy subjects were recruited for a prospective study and divided into two equal age groups (≤ 28 and ≥ 50 years old). Up to three measurements by a corneal deformation analyser based on the Scheimpflug principle were performed on the left eye of each subject. Raw Scheimpflu...
متن کاملScheimpflug imaging for keratoconus and ectatic disease
Scheimpflug cross-sectioning anterior segment imaging offers significant advantages over traditional placido based curvature analysis and ultrasound pachymetry. The accurate measurement of both the anterior and posterior corneal surfaces and the anterior and posterior lens allows for the creation of a three-dimensional reconstruction of the anterior segment. Changes on both the posterior cornea...
