the finite element method (fem) is one of advanced methods in modeling of solid mechanics used in the design and analyzing of prosthesis in the human body. one of the important factors in designing a femur (the linkage between basin and knee) which is under complicated stresses is to minimize the amount of the stress in the components of the prosthesis due to the body weight. in this research t...
Traveling to high altitudes can expose the eye to reduced ambient cold and low-pressure environments. These conditions can affect the physiology of the eye and may result in ocular problems and visual disturbances. In this paper, ocular disorders related to high altitudes are briefly reviewed. Then, high-altitude ocular disorders are categorized in three parts: those related to dry and cold env...
According to military documents, the incidence of ocular injuries significantly increases. Intraocular foreign body (IOFB) is one of the ocular damages that seriously threats vision. Many ocular injuries occurred in a war between Iran and Iraq from 1980 to 1988. The aim of the present study was to review ocular damages made by IOFB in this war, different methods of treatment and their prognosis.
Introduction: Recently the most accurate diagnostic method in the diagnosis of prosthesis infection is the combination of Tc-99m labeled leukocyte/bone marrow imaging. However the diagnostic efficiency of the test is influenced because of its low spatial resolution. Recently SPECT/CT imaging is implicated in this test with efficient additional diagnostic improvement. In the dep...
PURPOSE To test a prototype magnet system (magnetic levator prosthesis) for the ability to comfortably and non-invasively provide eye opening with maintenance of the blink in people with paralytic ptosis and determine preliminary efficacy for short-term clinical application. METHODS The prototype device consisted of a magnet on a spectacle frame and a micro-magnet array mounted externally on ...
