Living with Isolated ankyloblepharon filiforme adnatum

A rare condition present at birth in which thin bands of tissue join the upper and lower eyelids and keep the eye from opening fully.

Understanding Isolated ankyloblepharon filiforme adnatum

Isolated ankyloblepharon filiforme adnatum (AFA) is a condition in which thin bands of tissue connect the upper and lower eyelids.

One or several thin bands of connective tissue stretch between the eyelids, so the eye cannot open all the way. It is seen in newborns and infants. GARD reports that the bands should be removed to avoid lazy eye (amblyopia), and this can be done easily in the newborn period. It can happen alone or along with other conditions, such as trisomy 18.
