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 many possible causes of ptosis, and medical evaluation can help identify possible diagnoses, and hence guide what further testing and treatment may be needed (even if the initial ...

Eyelid edema is a condition in which the eyelids are swollen and tissues contain excess fluid. It may affect eye function when it increases the intraocular pressure. Eyelid edema is caused by allergy, trichiasis or infections. [4] The main symptoms are swollen red eyelids, pain, and itching. Chronic eyelid edema can lead to blepharochalasis.
In behavioural terms, microsleeps may manifest as droopy eyes, slow eyelid-closure, and head nodding. [2] In electrical terms, microsleeps are often classified as a shift in electroencephalography (EEG) during which 4–7 Hz ( theta wave ) activity replaces the waking 8–13 Hz ( alpha wave ) background rhythm.
