View source for Cyclopia

'''Cyclopia''' (pronounced: /saɪˈkloʊpiə/) is a rare form of [[congenital disorder]] that results in the formation of a single eye. The condition is named after the mythical one-eyed giants, the [[Cyclops]] from Greek mythology. 

==Etymology==
The term "Cyclopia" comes from the Greek words "kyklos" (κύκλος), meaning "circle" or "wheel", and "ops" (ὤψ), meaning "eye". It refers to the singular circular eye that characterizes this condition.

==Definition==
Cyclopia is a severe form of a spectrum of congenital conditions known as [[Holoprosencephaly]]. It is characterized by the development of a single eye, which is usually centrally placed in the area normally occupied by the root of the nose. 

==Symptoms and Diagnosis==
The most obvious symptom of Cyclopia is the presence of a single eye or a partially divided eye. A proboscis (a nose-like structure) may be present above the eye, but not always. Other symptoms can include missing or malformed facial features. Diagnosis is typically made at birth through physical examination, but it can also be detected through prenatal [[ultrasound]].

==Causes==
Cyclopia is caused by a disruption in the embryonic forebrain-dividing process. This can be due to genetic factors or environmental toxins. Some identified causes include [[Trisomy 13]], also known as Patau syndrome, and maternal use of certain drugs or alcohol during pregnancy.

==Treatment and Prognosis==
There is currently no cure for Cyclopia. Treatment is supportive and depends on the individual's specific symptoms. The prognosis for individuals with Cyclopia is poor, with most infants not surviving past birth.
