Blepharoptosis is as an alternative term
meaning the same as ptosis.
Blepharoptosis refers to the drooping of the upper eyelid,
that is the upper eyelid resting at a lower position than is normal. Either
just one eye (unilateral) or both eye (bilateral) may be affected.
Possible causes of blepharoptosis include:
- Disorder of the third cranial nerve, the oculomotor nerve.
In this case blepharoptosis is likely to be accompanied by
paralysis of eye movements.
.
- Horner's
Syndrome.
In this case blepharoptosis is likely to be accompanied by
a small pupil and absence of sweating on the affected side of the face
.
- Myasthenia Gravis.
In this case blepharoptosis will increase with fatigue (tiredness)
and be part of more widespread fatigue.
.
- Congenital.
In this case the blepharoptosis is present from birth.
.
- Disease of the eye muscles.
In this case the blepharoptosis is accompanied by weak or lacking
ability to move the eye.
Treatment options include addressing any treatable cause(s).
If appropriate, surgery may be recommended and may involve adjustments
to relevant tissues and facial
muscles.
