    Factors affecting pupil size after dilatation: the Twin Eye Study.



    Br J Opthalmology 2000;84:1173-1176.


      


    Pupil size after mydriasis is largely genetically determined with a heritability of up to 80%.

      


    506 twin pairs, 226 monozygotic (MZ) and 280 dizygotic (DZ) aged 49-79 were examined.

      


    Dilated pupil size was more highly correlated in MZ compared with DZ twins.

    Iris colour did NOT significantly contribute to the variance in dilatation.
