Polycoria

Polycoria or amaurosis?

Polycoria (or polykyrisis of the eyes - “Poly” - many, kyriazo - pupil translated from Greek) as a medical phenomenon means the presence of several pupils in one human eye. There are true and false polycoria. True polycoria manifests itself as a clinical picture when the pupils exceed the size of the iris and move freely in the eye without disappearing under the eyelid. This pathology is congenital and causes quite serious suffering to the child, and if vision loss occurs in such an eye or dystrophic changes are observed, then it is removed. False polycoria is an ophthalmological disease when the eye itself is healthy, but when exposed to light, the irises of both pupils become almost transparent or discolored. There is also hypertrichosis of the iris, in which the number of its vascular elements is significantly increased. Treatment of both diseases is carried out only after a thorough examination of the patient.

False polycoria can occur in both an adult and a child, however, most often it occurs as a result of pathologies of the central nervous system and parasympathetic nervous system. Typically, the symptoms of false polycoria in children may appear slightly, but disappear on their own over time (most often as the child grows and higher nervous structures develop). In addition, in adults, for example, false polycoria is often accompanied by neurological disorders and sometimes leads to irreversible changes. Doctors distinguish: a subclinical form of the disease, characterized by the absence of pathological symptoms, as well as an acute form, accompanied by a sharp decrease in vision, profuse lacrimation, dizziness and nausea
