CFEOM. Congenital fibrosis of the extraocular muscles is a class of rare genetic disorders affecting one or more of the muscles that move the eyeballs. Individuals with congenital fibrosis of the extraocular muscles (CFEOM) have varying degrees of ophthalmoplegia (an inability to move the eyes in one or more directions) and ptosis.
Muscle–eye–brain ( MEB) disease, also known as muscular dystrophy-dystroglycanopathy congenital with brain and eye anomalies A3 ( MDDGA3 ), [2] is a kind of rare congenital muscular dystrophy (CMD), largely characterized by hypotonia at birth. Patients have muscular dystrophy, central nervous system abnormalities and ocular abnormalities.
The extraocular muscles, or extrinsic ocular muscles, are the seven extrinsic muscles of the eye in humans and other animals. [1] Six of the extraocular muscles, the four recti muscles, and the superior and inferior oblique muscles, control movement of the eye. The other muscle, the levator palpebrae superioris, controls eyelid elevation.

[1] It occurs most commonly in individuals with Graves' disease, [2 ...
Semaglutide, the active ingredient in Ozempic and Wegovy, has become a hugely popular medication thanks to its effectiveness for weight loss. But a growing body of research has linked the ...
Blepharospasm is a neurological disorder characterized by intermittent, involuntary spasms and contractions of the orbicularis oculi (eyelid) muscles around both eyes. These result in abnormal twitching or blinking, and in the extreme, sustained eyelid closure resulting in functional blindness.
Voila! The pinhole helps focus the light, creating a clearer image. (Of course, most of us use glasses or contact lenses to correct refractive errors — they’re much more efficient!) 7. Your ...
Rapid eye movement sleep ( REM sleep or REMS) is a unique phase of sleep in mammals (including humans) and birds, characterized by random rapid movement of the eyes, accompanied by low muscle tone throughout the body, and the propensity of the sleeper to dream vividly. The REM phase is also known as paradoxical sleep ( PS) and sometimes ...
