متن کاملStudy of Optical Models Regarding the Human Eye
Introduction: Until now, many models have been presented for optical study of the human eye. In recent years, surgery on the anterior section of the eye (such as cataract and photo-refractive surgery) has increased, so a study on the optics of the eye and evaluation of vision quality has become more important. Material and Methods: In this article, some of these models are considered. They incl...
متن کاملUse of three-dimensional ultrasonography of the eye and measurement of optical long axis in dog
This study was conducted to determine the use of three-dimensional ultrasonography (3DU) in ocular imaging of the dog and measuring of its optical axis. 12 healthy mixed-breed dogs including 6 males and 6 females were studied. 3DU of the eyes were done using a 5–12 MHz linear trapezoid transducer. 3DU of the eyes were evaluated and the normal optical long axis through a line between the cornea ...
