The crypts are little squiggly lines that radiate out around the pupil; with this condition, thick round or oval openings can be seen.On diagnosis, signs lead to symptoms where there is more than one set of iris muscles, which controls the amount of light being brought into the eye. When the iris becomes deformed, it will disarrange the control of light coming in leading to blurred vision and finding it hard to visually focus. Polar cataracts will also be present in this condition where a round, opaque malformation of distorted lens fibers is located in the central posterior part of the lens showing disformality. Blindness may also be caused due to damage of the optic nerve from glaucoma. Treatment
Polycoria has been linked to hereditary genetics, and also associated with polar cataracts, glaucoma, and retinal detachment. Not all cases are treated for this iris abnormality, but when cases are treated the only treatment is surgical procedure and life-long ocular monitoring that is highly recommended. Considerations for surgery are surgical correction, intraocular surgery, and/or reapproximation, as if it was being treated for glaucoma or retinal detachment. Children under the age of 3, who do not seek surgical surgery, have responded well with miotic drops that contained mydriatic/cycloplegic, allowing the separate eye sphincters to dilate and constrict together. This allows improved  balance of uncorrected visual acuity.
History
Since true polycoria and pseudopolycoria are so rare, there is not much history on the disorders in the tradition of modern western medicine. According to an article published in 2002, there have only been 2 cases of true polycoria since 1966.Early Chinese history names multiple legendary figures as having double pupils, which as a result was led to a beliefs that a child born two double pupils were destined to be a great king or sage. Xiang Yu, Hegemon of Chu, blood brother and later arch nemesis of Liu Bang, the founding emperor of the Han dynasty, was given great esteem due to his prowess in combat and auspicious double pupil. After overthrowing the Qin dynasty together, he was named Hegemon of the loose series of kingdoms he created in its wake, while he gave Liu Bang the remote province of Han. The Civil War that followed called the Chu-Han contention, ending with a Han victory and a legendary last stand by the Hegemon. See also
