Abstract Accommodation lag is important factor for normal vision. Higher of accommodation may cause various ocular symptoms particularly during near tasks. In this study, the was assessed in peripheral retina and it compared with central accommodative aberrometer. cross-sectional fifty-three young subjects visual acuity without any active disease or past surgery were included. Aberrations field...

Abstract Coma is one of the most common ocular higher order aberrations and highly affects quality image. It assumed that corneal are balanced by internal (lenticular) so retinal image may not have great impact. However, during accommodation, shape, position, curvature crystalline lens changes which might disrupt this balance between aberration. This study aimed to investigate effect accommodat...

when a child presented with decreased level of consciousness in the emergency room, taking the right approach is one of the most important skills that every emergency physician should have. ideally, there should be a defined diagnostic and therapeutic algorithm in the emergency room for managing these children in order to minimize difficulties diagnostically and maximize time spent helping the ...

extract  although there are new ways to portray the brain, colored and computerized encephalography but coma is still unknown and such as death remain beyond comprehension and knowing. is not it ?   perhaps because of this, despite knowing that some part of the brain is not yet fully understood all its parts. but knowing the components that working to each other is key for discovering a lot of ...

conclusions toxic causes with an incidence of 49.6% were the most common cause of loss of consciousness among all age groups. results among the 123 children under investigation, 76 cases were male (61.8%) and 47 females (38.2%) with the mean age of 3.2 ± 0.64 years. the most common causes of loss of consciousness among children were as follows: toxic causes in 61 patients (49.6%), infectious ca...

PURPOSE To compare corneal higher-order aberrations (HOAs) between normal and keratoconic eyes, and to investigate the association between elevation-based corneal topographic indices and corneal wavefront data in the latter group. METHODS In this cross-sectional comparative study, 77 normal right eyes of 77 control subjects and 66 eyes of 36 keratoconic patients were included. In each eye, el...
