'''Cyclopia''' (named after the Greek mythology characters [[cyclopes]]), also known as '''alobar holoprosencephaly''', is the most extreme form of [[holoprosencephaly]] and is a [[congenital disorder]] (birth defect) characterized by the failure of the embryonic [[prosencephalon]] to properly divide the [[Orbit (anatomy)|orbits]] of the eye into two cavities. Its incidence is 1 in 16,000 in born animals and 1 in 200 in [[miscarriage|miscarried fetuses]].<ref>''Taber's Cyclopedic Medical Dictionary'', {{ISBN|0-8036-0654-0}}</ref><ref>[[Armand Marie Leroi|Leroi, Armand Marie]] ''Mutants: On Genetic Variety and the Human Body'', p.73. {{ISBN|978-0142004821}}</ref>
