Introduction: There is a limited number of case reports published in the past decade confirming the radio-iodine presence in the tear. These observations as well as reported cases of salivary and lacrimal gland dysfunction after radioiodine therapy stimulated investigators to clarify whether lacrimal gland function can be affected post-radioiodine therapy. Hence we ...

purpose: to analyze the results of scanning slit topography (orbscan ii, bausch & lomb) in both eyes of patients with unilateral fuchs’ heterochromic iridocyclitis methods: an intra-subject non-interventional case-control study was conducted on patients with unilateral fuchs’ heterochromic iridocyclitis (fhi). none of the patients had history of ocular surgery. corneal topographic parameters ob...

Binocular rivalry occurs when the images presented to the two eyes do not match. Instead of fusing into a stable percept, perception during rivalry alternates between images over time. However, during rivalry, perception can also resemble a patchwork of parts of both eyes' images. Such integration of image parts across eyes is relatively rare compared to integration of image parts presented to ...

The purpose of the present study was to examine in 7 years old normal children who just learnt to read, saccade and fixation characteristics during reading single words. Eight children were studied and their results were compared to those of eight normal adults doing the same task. For each group word reading data were also compared with data in a task requiring saccades and fixations to target...

purpose: to evaluate the predictability, efficacy, and safety of iris-claw artisanô phakic intraocular lenses ­for myopia. methods: through a prospective clinical study, 35 eyes of 21 patients with myopia from -5 to 26.5 diopters underwent implantation of the artisan lens. patients were examined 1, 3, and 7 days (all eyes); 1 month (28 eyes), 3 months (29 eyes), and 6 months (32 eyes) after the...

purpose : to investigate and compare the causes of blindness in ocular behçet’s disease (bd) in men and women methods : in a retrospective, descriptive investigation from 1976 to 2008, 6,021 bd cases were registered in our bd unit of shariati hospital of tehran university of medical sciences (tums). at the last visit, 187 patients (124 men and 63 women) were blind (vision=1/10 or less) at least...

purpose: to assess foveal thickness by spectral-domain optical coherence tomography (sd-oct) during acute anterior uveitis (aau) in hla–b27 patients. methods : foveal thickness was measured at baseline and after clinical resolution of the uveitis. data of the affected eyes of 11 patients were compared to those of a fellow, healthy eyes and to those of counterpart volunteers. results: at basel...

Despite the incredible diversity among extant eyes, laws of physics constrain how light can be collected resulting in only eight known optical systems in animal eyes. Surprisingly, all animal eyes share a common molecular strategy using opsin for catching photons, but there are a diverse collection of mechanisms with proteins unrelated to each other used to focus light for vision. However, opsi...

Last November I visited Japan for the first time and was lucky enough to visit individual labs at four different universities. As I talked with my hosts and their students I was struck by the differences between the scientific cultures of Japan and the United States. At its best, American science is all about the triumph of excellence in the land of opportunity, with 27-year-old assistant profe...
