Topical phenylephrine for mydriasis affects rabbit retinal pigment epithelial transport.
Rabbit retinal pigment epithelium (RPE) has an alpha-1 adrenoreceptor that substantially reduces RPE short circuit current (Isc) when stimulated. Since phenylephrine is a potent alpha adrenergic agonist frequently used to obtain pupil dilation, we examined the effect of topically applied phenylephrine for pupil dilation on RPE transport. Naive black dutch-belted rabbits received either one drop...
متن کاملDose-response relationship for light intensity and ocular and electroencephalographic correlates of human alertness.
Light can elicit both circadian and acute physiological responses in humans. In a dose response protocol men and women were exposed to illuminances ranging from 3 to 9100 lux for 6.5 h during the early biological night after they had been exposed to <3 lux for several hours. Light exerted an acute alerting response as assessed by a reduction in the incidence of slow-eye movements, a reduction o...

PURPOSE To investigate the rate and the degree of the ocular hypertensive response to dexamethasone ointment in children undergoing eyelid surgery. METHODS Dexamethasone ointment (Dexcosil) was applied three times a day for the first week and twice a day for the second to third week postoperatively to children undergoing epiblepharon surgery. Intraocular pressure (lOP) was measured on the day...

متن کاملDetermination of dose-response relationship in cultured human lymphocytes for biological dosimetry
Background: Lymphocyte-dicentric assay is the most generally accepted method for biological dosimetry of overexposed individuals. In this study, the frequency of unstable chromosome aberration in blood lymphocytes was used to estimate radiation dose received by individuals. Evaluation of dose using a calibration curve produced elsewhere may have a significant uncertainty therefore, experiments ...
