Pupula Duplex is a latin term which means double pupil. Its often referred by some by the following terms "evil eye", double iris and in medical literature as Polycoria. It is thought to be a condition where a person develops two irises, corneas and retinas on the same eyeball of each eye. It is really a mutation within th iris. This condition does not officially exist in official medical literature. Since there isn’t a great deal of evidence in the form of official literature supporting the existence of this condition, many people believe it is simply mythological It is often portrayed in science fiction literature. Although it is an extremely rare condition there are a few cases of famous historical figures who were born with this condition. This condition was given some credence when the famous Chinese emperor Liu Ch'ung was featured on Ripley’s believe it or not as having had this condition. It is thought to be condition that a person is born with. Since no official medical literature exists on this condition there is limited information available related to its possible causes? It is most likely a result of a genetic defect or mutation. It is not thought to be something that can be transmitted genetically. It isn’t contagious nor is it thought to be harmful to the person’s general health.
A common question that most people who encounter this condition are likely to ask are does a person with this condition see from pupils? Well before we can answer this questions let us briefly delve into how a person with normal eyesight sees.
When light enters the eye of a normal person it passes through the cornea. The cornea is the transparent front section of the eye that covers the iris. The cornea helps your eye to focus. The light then approaches the other side of the cornea called the aqueous humor then it passes through the pupil or the iris. The iris contracts or dilates depending on the amount of light that may be present hereby increasing or limiting the amount of lie that progresses deeper into the eye. The light then travels through the lens that is responsible for focusing the light. This focused light is then transported to the center of the eye covered in a clear jelly called vitreous which is surrounded by the retina.
The light is picked up by the photoreceptors in the retina where it is projected unto a flat and smooth surface. Signals are then sent from the photoreceptors to the optic nerve where it is translated into electromagnetic signals where its then sent to the visual center of the brain for interpretation.
A person who has a double pupil may have the ability to increase the volume of visual information that is taken in when he sees. His focus may also be vastly improved. It is highly unlikely that this person will see separately in the same eye as the information will travel from the same photoreceptors in that particular eye. Since this condition has not been studied in any great detail it is not well understood how the brain would interpret the information sent by the eye of a person with a Pupula Duplex. Another equally understandable question is does a person with this condition have double vision in the affected eye? It seems possible and even likely given that all the mechanisms for seeing are replicated in each iris.
Is Pupula Duplex and Polycoria the Same
According to wikipedia, Polycoria is a medical condition characterized by more than on Pupillary openings within the iris. Even though the term Pupula Duplex may not officially exist in medical literature, it seems it is categorized under this term called Polycoria. Does this give credence to the existence of this medical condition? It quite possibly does, however the verified cases of persons who have suffered from this condition is still decidedly low. Polycoria is often referred to as pseudopolycoria. Why? It is said that only of the pupils is the real pupil which is often referred to as a iris sphincter muscle.
Mythical or not the condition Pupula Duplex has captured the imagination of many persons and images like the ones used in this article has been going viral on the web..
