Purpose To measure the maximum, objectively measured, accommodative amplitude, produced by pharmacologic stimulation. Methods Thirty-seven healthy subjects were enrolled, with a mean age of 20.2±1.1 years, corrected visual acuity of 20/20, and mean spherical equivalent refraction (SER) =-0.83±1.60 diopters. For each subject, the right pupil was dilated with phenylephrine 10%. After 30 minutes...

Subjects maintained their eyes crossed (verged) for a period of 8 min in darkness with monitoring provided by an infrared video system. Changes in resting vergence (RV) and resting focus (RF) were examined. Results showed: (i) visual stimulation was not necessary for adaptation of either RV or RF, but (ii) these purely motor effects were significantly smaller and more dissipative than those att...

conclusions the pattern of visual impairment in learning-impaired children is not much different from that in normal children; however, because these children may not be able to express themselves clearly, lack of correct diagnosis and appropriate treatment has resulted in a marked defect in recognizing visual disorders in these children. therefore, gaining knowledge of the prevalence of refrac...

background & aim :facilitating people’s access to necessary health services is one of the most important strategies to reach social justice within countries’ health system. therefore in-time access to health cares and ensuring desirable results are essential. this study was conducted to evaluate the perception of martyrs’ parents of accessing the services of health monitoring plan. materials an...

Asymptotic expansions were first introduced by Henri Poincaré in 1886. This paper describes their application to the semi-classical evaluation of amplitudes in quantum field theory with boundaries. By using zeta-function regularization, the conformal anomaly for a massless spin-12 field in flat Euclidean backgrounds with boundary is obtained on imposing locally supersymmetric boundary condition...

The problem of time, considered as a problem in the usual physical context, is reflected in relation with the paper by Kauffman and Smolin ([5]). It is shown that the problem is a misposed problem in the sense that it was raised with a lack of the recognition of mathematically known facts. We found an idea on time similar to ours in the paper “A possible solution to the problem of time in quant...

For a long time basic accommodation capacities represented the dominant type of accommodation in tourist offer, while at the same time complementary accommodation capacities were neglected. However, recently there has been a growing interest for complementary, substitute types of tourist accommodation, both in the Republic of Croatia and in Dubrovnik, where since 2000 a significant increase of ...

because of its kinetic nature and computational advantages, the lattice boltzmann method (lbm) has been well accepted as a useful tool to simulate micro-scale flows. the slip boundary model plays a crucial role in the accuracy of solutions for micro-channel flow simulations. the most used slip boundary condition is the maxwell slip model. the results of maxwell slip model are affected by the ac...

We measured apparent accommodation in 42 pseudophakic eyes (34 patients) after implantation of posterior chamber intraocular lenses. The mean apparent accommodation was 2.03 +/- 1.03 diopters. The mean accommodative power of 16 phakic eyes used as controls was 2.91 +/- 1.29 diopters. The diameter of the pupil appeared to be the most important factor in apparent accommodation--the smaller the pu...
