Palpebral fissure
Palpebral fissure is the anatomic name for the separation between the upper and lower eyelids. In adults, this measures about 10mm vertically and 30mm horizontally. It can be reduced in horizontal size by fetal alcohol syndrome and in Williams Syndrome. The chromosomal conditions Trisomy 9 and Trisomy 21 can cause the palpebral fissures to be upslanted, while Marfan Syndrome can cause a downslant. The fissure may be increased in vertical height in Graves' disease, which is manifested as Dalrymple's sign. This is one of the numerous symptoms of genetic disorders like Cri-du-chat. Narrowing of the fissure can be a prominent indicator of myofascial trigger points in the ipsilateral sternocleidomastoid muscle's sternal division, a common cause of tension headaches, particularly those felt around the eyes & sinuses. In animal studies, using four times the therapeutic concentration of the ophthalmic solution Latanoprost, the size of the palpebral fissure can be increased. The condition is reversible. Latanoprost is a prostaglandin F receptor agonist.
