background: the purpose of this study was to investigate the various gantry angle and ssd dependencies of tld and mosfet dosimeters. materials and methods: lif (mg) tld and mosfet were used in this study. dosimeter systems were calibrated and then irradiated at various gantry angle and ssd by applying 6 mv photon energy. results: based on the results, mosfet changes were found to be in 2% range...

background the gonial angle is one of the most important measurements required for orthodontic treatment and orthognathic surgery. it is difficult to determine the accurate measurement of each gonial angle on cephalometric radiographs because of superimposition of the left and right angles. objectives the aim of the present study was to determine the right and left gonial angles on panoramic ra...

purpose : to determine the association between retinal vascular diameter and its branching angles with diabetic retinopathy (dr) stages in diabetic patients methods : a descriptive analytic cross-sectional study was conducted in 62 diabetic patients (120 eyes) referred to farabi eye hospital between june 2008 and december 2009. digital fundus photography pictures were imported into photoshop so...

background: chondromalacia patella is the most common cause of mechanical knee pain in young women. q angle and knee alignment are important clinical parameters for biomechanics of the patellofemoral joint. objective: to identify the prevalence of knee malalignment and to find out if there is a correlation between knee mal alignment and q angle with age at onset of disease. methods: all patient...

The normal carrying angle in Shiraz population was measured on the basis of sex and age. The right elbow angle of 4266 cases was examined from birth to 30 years old. This study found the carrying angle in 2540 females to be 7.20 (range 2-19) and in 1726 males to be 6.40 (range 2-11), a 0.80 difference. A significant difference (p= 0.05) was found in relation to age. There is a gradual incr...

AIM To estimate the prevalence of glaucoma among people worldwide. METHODS Available published data on glaucoma prevalence were reviewed to determine the relation of open angle and angle closure glaucoma with age in people of European, African, and Asian origin. A comparison was made with estimated world population data for the year 2000. RESULTS The number of people with primary glaucoma i...

Although glaucoma is a major global cause of blindness, the lack of a uniform definition of the disease in its different forms makes it difficult to assess its public health impact. By considering the common features of glaucoma, we have analysed available data on the three main forms of the disease: congenital/hereditary glaucoma, primary open-angle, and primary angle-closure glaucoma. A simpl...

To analyze the epidemiologic characteristics of hospitalized patients with glaucoma at Shanghai Eye and Ear, Nose, and Throat Hospital in the relative well economic condition area Eastern China.Researchers reviewed the 10 years charts of patients with a discharge diagnosis of glaucoma at this hospital from January 2004 to December 2013. With the criteria used for diagnoses of different types of...
