Myogenic ptosis, which includes oculopharyngeal muscular dystrophy, myasthenia gravis, myotonic dystrophy, ocular myopathy, simple congenital ptosis and blepharophimosis syndrome. Aponeurotic ptosis, which may be involutional or postoperative. Mechanical ptosis, which is the result of edema or tumors of the upper lid.
Blepharophimosis forms a part of blepharophimosis, ptosis, epicanthus inversus syndrome (BPES), also called blepharophimosis syndrome, which is an autosomal dominant condition characterised by blepharophimosis, ptosis (upper eyelid drooping), epicanthus inversus (skin folds by the nasal bridge, more prominent lower than upper lid) and telecanthus (widening of the distance between the inner ...
There are also several abnormal cranial nerve synkineses, both acquired and congenital. Marcus Gunn jaw-winking is an example of a pathologic congenital synkinesis. First described by the ophthalmologist Marcus Gunn in 1883, [3] this condition presents in approximately 5% of neonates with congenital ptosis.
Blepharophimosis-ptosis-esotropia-syndactyly-short stature syndrome is a very rare genetic and congenital disorder which is characterized by blepharophimosis, ptosis, V-esotropia, foot syndactyly, extra-ocular and frontal muscles weakness, low height/short stature, prognathism, and synophrys.
It is a dynamic sign, whereas lid lag is a static sign which may also be present in cicatricial eyelid retraction or congenital ptosis. A pseudo Graefe's sign (pseudo lid lag) shows a similar lag, but is due to aberrant regeneration of fibres of the oculomotor nerve (III) into the elevator of the upper lid. [2] It occurs in paramyotonia ...
Reconstructive surgery is usually required in order to increase cranial space, correct tear duct stenosis, and/or correct ptosis of the eyelids in order to prevent amblyopia (lazy eye). [2] Midfacial surgery may also be required during early childhood to correct respiratory problems, dental malocclusion, and swallowing
Dermatochalasis is caused by a loss of elasticity in the connective tissue supporting the structure of the front portion of the eyelid. [3] Normally, in Caucasians, the orbicularis muscle and overlying skin form a crease near the tarsal border. [3]
The ptosis of Horner syndrome can be quite mild or barely noticeable (partial ptosis). [7] When anisocoria occurs and the examiner is unsure whether the abnormal pupil is the constricted or dilated one, if a one-sided ptosis is present then the abnormally sized pupil can be presumed to be on the side of the ptosis.
