Ankyloblepharon is divided into: external ankyloblepharon [ankyloblepharon - external] and internal ankyloblepharon [ankyloblepharon - internal] The appearance of ankyloblepharon may simulate strabismus clinically. The eyelid fusion is extensive and not limited to the epithelium. Hence it is probably not due to an impaired separation of the embryonic epithelial eyelid margin adhesions. Ankyloblepharon is often associated with microphthalmia and other ocular developmental anomalies. Ankyloblepharon filiforme adnatum is a rare variant of ankyloblepharon.
