purpose: to measure the upper eyelid crease landmarks in an iranian population sample. methods: we studied 208 iranian subjects aged 30 to 50 years. upper eyelid crease height was measured in lateral, medial and central positions using calipers. levator function (lf) was also evaluated after exclusion of frontalis muscle function. results: mean age was 39.1±5.9 years and female to male ratio wa...

BACKGROUND The use of medial rectus pulley posterior fixation sutures to treat esotropia with convergence excess has limited support in the literature. We describe our results using this technique to treat patients with large near-distance disparities. METHODS We retrospectively analyzed records of patients with accommodative or partially accommodative esotropia and convergence excess 13(Δ) o...

PURPOSE To evaluate postoperative outcomes and visual performance in intermediate distance after implantation of a +1.5 diopters (D) addition, aspheric, rotational asymmetric multifocal intraocular lens (MIOL). METHODS Patients underwent bilateral cataract surgery with implantation of an aspheric, asymmetric MIOL with +1.5 D near addition. A complete ophthalmological examination was performed...

A theoretical relation is presented between the seismological Fourier amplitude spectrumand the mean squared value of the elastic response, which is defined by Gaussian distribution. Byshifting a general process to its mean value, spectrum of the mean squared value of the displacementis computed from the Fourier amplitude spectrum and the real part of the relative displacementtransfer function ...

in this research, the spatial distribution of fe, cu, zn and mn on agricultural lands of golestan province were evaluated using different interpolation methods such as, kriging, inverse distance weighted, local polynomial, inverse multiquadric and radial basis function. thus, 505 soil samples were provided from fields during 2008 and micronutrients rates were measured for each sample. the perfo...
