Mydriasis (C0026961)

Definition (MSHCZE) Rozšíření zornice (pupily). Za normálních okolností vzniká při slabém osvětlení (umožní průnik většího množství světla do oka). Je zprostředkována svalem (m. dilator pupillae), který je v duhovce a který je inervován sympatikem. Opak: mióza. M. je možné docílit i léky (mydriatika). M. zvyšuje nitrooční tlak (viz glaukom), proto se tyto léky při glaukomu nesmějí podávat. (cit. Velký lékařský slovník online, 2013 http://lekarske.slovniky.cz/ )
Definition (MSH) Dilation of pupils to greater than 6 mm combined with failure of the pupils to constrict when stimulated with light. This condition may occur due to injury of the pupillary fibers in the oculomotor nerve, in acute angle-closure glaucoma, and in ADIE SYNDROME.
