Symptoms & Signs. Dilation, or widening, of the pupils of the eyes is normal in conditions of low light in order to allow more light to reach the retina. Medically, dilation of the pupils is known as mydriasis. Specific medications known as mydriatics are administered to dilate the pupils for ophthalmologic examination.
Cycloplegic drugs paralyze the ciliary muscles of the eye and keep the pupil open longer. Atropine, a cycloplegic, is a drug that has long lasting effects; if atropine is given, the pupil may stay dilated for two weeks, according to the Mayo Clinic. Eyes may water or redden from cycloplegic drops, also according to Mayo, and eyelids may swell.
