Pupil-dilation drops required for a thorough diagnosis and treatment of eye diseases
A few years ago at the Grand balls ladies fascinated gentlemen sparkling, unusually expressive eyes. Their pupils were wide open. For cosmetic reasons ladies used "Atropine", burying him in the eye.
In Soviet times, "Atropine" is widely used in ophthalmology. But today it is almost abandoned. "Atropine" is a lot of disadvantages.

Well tolerated by patients "Mydriacyl (Mydrum", "Tropikamid"). Pupils are maximally increase after 15-20 minutes. And narrowed about three hours. It is very convenient as visual acuity and full human performance recover fairly quickly. Instilled with the drug for adults and children.
However, "Mydriacyl" should be used cautiously if increased intraocular pressure or there is inflammation of the ocular apparatus. It is undesirable to use it at a deep enough anterior chamber.
Similarly, there are and drop the "Zycloned". It should not be confused with drops "Cipromed" – is an antibiotic that treat infections of the eye! Drug "Cyclamed" dilates the pupils for a longer time, from 6 to 12 hours or even longer.
