The fissure may be increased in vertical height in Graves' disease, which is manifested as Dalrymple's sign. It is seen in disorders such as cri-du-chat syndrome. 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.
Rarely, when infections of the canine space erode into the infra-orbital vein or the inferior ophthalmic vein (via the sinuses), there can be spread via the common ophthalmic vein through the superior orbital fissure and into the cavernous sinus. This can result in septic cavernous sinus thrombosis, which is a rare, but life-threatening ...
Along the inner margin of the tarsus are modified sebaceous glands known as tarsal glands (or meibomian glands), aligned vertically within the tarsi: 30 to 40 glands in the upper lid, and 20 to 30 in the lower lid, which secrete a lipid-rich product which helps keep the lacrimal secretions or tears from evaporating too quickly, thus keeping the ...
