Blepharitis, sometimes known as granulated eyelids, is one of the most common ocular conditions characterized by inflammation, scaling, reddening, and crusting of the eyelid. This condition may also cause swelling, burning, itching, or a grainy sensation when introducing foreign objects or substances to the eye.
Von Graefe's sign is the lagging of the upper eyelid on downward rotation of the eye, indicating exophthalmic goiter (Graves' disease). [1] It is a dynamic sign, whereas lid lag is a static sign which may also be present in cicatricial eyelid retraction or congenital ptosis.
Droopy eyelids can give the face a false appearance of being fatigued, uninterested or even sinister. The eyelid may not protect the eye as effectively, allowing it to dry. Sagging upper eyelids can partially block the field of view. Obstructed vision may necessitate tilting the head backward to speak.
The upper eyelid crease is a common variation between people of White and East Asian ethnicities. [9] Westerners commonly perceive the East Asian upper eyelid as a "single eyelid". [9] However, East Asian eyelids are divided into three types – single, low, and double – based on the presence or position of the lid crease. [10]
An epicanthic fold or epicanthus [6] is a skin fold of the upper eyelid that covers the inner corner (medial canthus) of the eye. [3] However, variation occurs in the nature of this feature and the possession of "partial epicanthic folds" or "slight epicanthic folds" is noted in the relevant literature.
The levator palpebrae superioris receives motor innervation from the superior division of the oculomotor nerve. [1] [2] [3] The smooth muscle that originates from its undersurface, called the superior tarsal muscle is innervated by postganglionic sympathetic axons from the superior cervical ganglion.
The canthus (pl.: canthi, palpebral commissures) is either corner of the eye where the upper and lower eyelids meet. [1] More specifically, the inner and outer canthi are, respectively, the medial and lateral ends/angles of the palpebral fissure. The bicanthal plane is the transversal plane linking both canthi and defines the upper boundary of ...
In mild disease, patients present with eyelid retraction. In fact, upper eyelid retraction is the most common ocular sign of Graves' orbitopathy. This finding is associated with lid lag on infraduction (Von Graefe's sign), eye globe lag on supraduction (Kocher's sign), a widened palpebral fissure during fixation (Dalrymple's sign) and an incapacity of closing the eyelids completely ...
