What is Ankyloblepharon and explain in detail?
Ankyloblepharon is defined as the adhesion of the edges of the upper eyelid with the lower eyelid. Ankyloblepharon must be differentiated from blepharophimosis, in which palpebral aperture is reduced and there is telecanthus, but the eyelid margins are normal. Another condition similar to ankyloblepharon is symblepharon, in which the palpebral conjunctiva is attached to the bulbar conjunctiva. Recognition of ankyloblepharon necessitates systemic examination to detect associated abnormalities such as genitourinary and cardiac abnormalities and syndactyly.

Presentation
Complication
The main complication of congenital ankyloblepharon is amblyopia.  Timely separation of the eyelids is very important to avoid the development of occlusion amblyopia.

Etiology
Ankyloblepharon may be congenital or acquired. The most common type is congenital.Clinically, ankyloblepharon may be complete, partial, or interrupted. Complete ankyloblepharon is when the eyelids are fused throughout the lid margins. In the partial form, they are joined at one or more points
