Quick Facts
The capsulopalpebral fascia is a fibrous expansion originating from the fascial sheaths surrounding the inferior rectus and inferior oblique muscles. It assists with the depression of the lower eyelid when the inferior oblique and inferior rectus muscles contract.
Structure and/or Key Feature(s)
The capsulopalpebral fascia is a fibrous expansion originating from the fascial sheaths surrounding the inferior rectus and inferior oblique muscles (Dutton, 2011).
Anatomical Relations
The capsulopalpebral fascia attaches to the suspensory ligament of the eyeball. Fibers ascend to the inferior tarsal plate and the dermis of the lower eyelid, thus creating a crease in the skin of the lower eyelid.
Function
The capsulopalpebral fascia is described as the analog to the levator palpebrae muscle. It inserts into the inferior tarsal plate and dermis of the lower eyelid, thus assisting with the depression of the lower eyelid when the inferior oblique and inferior rectus muscles contract.
