Factors affecting pupil size after dilatation: the Twin Eye Study.
BACKGROUND/AIMS Well dilated pupils make eye surgery easier. A classic twin study was established to examine the relative importance of genes and environment in the variance of pupil size after mydriasis, and to examine the effects of other factors such as age, iris colour, and refractive error. METHODS 506 twin pairs, 226 monozygotic (MZ) and 280 dizygotic (DZ), aged 49-79 (mean age 62.2 yea...

متن کاملDistribution and heritability of iris thickness and pupil size in Chinese: the Guangzhou Twin Eye Study.
PURPOSE To investigate the distribution and heritability of iris thickness and pupil diameter measured by anterior segment optical coherence tomography (ASOCT) in a classic twin study. METHODS Twins aged 8 to 16 years were enrolled from the Guangzhou Twin Registry. ASOCT was used to obtain one horizontal scan, and the images were analyzed with custom software. Iris thickness was measured at 7...
متن کاملFactors affecting the acquisition of expert tacit knowledge Case study: Delivery time in twin pregnancy
This paper discovers the necessary variables need for creating models for tacit knowledge acquisition, especially in medical care services. The case studied here, was knowledge of diagnosing and time of delivery in twin pregnancy with nuchal translucency screening. This paper covers the empirical work undertaken on semi-structured interview based on thematic analysis. With regard of theoretical...
متن کاملAngle-closure, pupil dilatation, and pupil block.
PREVious papers (Lowe, 1964a) have remarked that when the pupils of eyes with shallow anterior chambers, narrow angles, and open peripheral iridectomies are dilated with homatropine, a considerable proportion of the eyes with persistently narrow angles develop angle-closure, a consequent fall in outflow facility, and a rise in intra-ocular pressure that may reach the fifties within two hours. W...
