ptózu

Ptózu is a term with unclear status in widely used medical and scientific literature. In many sources it may be encountered as a misspelling or dialect form of ptózis (ptosis), which describes the drooping or sagging of a body part, most commonly the eyelid. When used in this uncertain way, its exact meaning can vary by context and language.

If intended to refer to ptosis, the concept covers congenital and acquired forms. Congenital ptosis is present at birth and results from developmental issues with the levator palpebrae superioris muscle. Acquired ptosis can arise from nerve palsies (such as oculomotor nerve involvement), myasthenia gravis, Horner’s syndrome, trauma, vascular or degenerative changes, or aging that weakens eyelid support structures. Symptoms typically include a visibly drooping upper eyelid and may reduce the visual field; compensatory brow elevation is sometimes observed.

Diagnosis relies on clinical examination, with measurements such as the margin reflex distance (MRD1) to assess eyelid position. Additional tests or imaging may be used to identify underlying causes in cases where systemic disease or neurological involvement is suspected.

Treatment depends on cause and functional impact. Functional ptosis may be corrected surgically through levator resection, advancement, or frontalis suspension techniques; cosmetic considerations also influence choice. Non-surgical options, such as a ptosis crutch in eyeglasses, can provide temporary support.

Etymology traces to the Greek ptōsis meaning falling or sinking. See also ptosis, eyelid disorders, and ophthalmic surgery. If you meant a different term or a local usage, please specify for a more precise article.
