Platycoria is a medical condition characterized by an abnormal dilation of the pupils. It is derived from the Greek words "platys," meaning flat or broad, and "kore," meaning pupil. This condition is also known as megalokornea or massive mydriasis.
The pupils, which are normally circular and constrict or dilate in response to light, become unusually enlarged and fail to constrict properly. Platycoria can occur as a result of various underlying causes, including certain genetic disorders, ocular trauma, inflammation of the iris, or side effects of medication.
Individuals affected by platycoria may exhibit symptoms such as increased sensitivity to light, blurred vision, or difficulty focusing. The condition can range in severity, with some individuals experiencing mild dilation of the pupils while others may show significant enlargement.
Diagnosis usually involves a comprehensive eye examination by an ophthalmologist, including measuring the size of the pupils, checking for any associated abnormalities, and determining the underlying cause. Treatment options depend on the specific cause and severity of platycoria. In some cases, no treatment may be necessary if the condition is congenital and does not cause any functional problems. However, in cases where platycoria is a result of an underlying condition, treating the root cause can help manage or resolve the dilation.
Overall, platycoria is a medical term that refers to an abnormal and pronounced enlargement of the pupils, which may necessitate further investigation and treatment to address any related visual impairments or discomfort.
