- Which clinical findings or investigations would complement this observation?
Reveal the explained reading
Ptosis
- Site
- Upper eyelid
- Laterality
- Unilateral or bilateral
- Variability
- Fixed or fatigable
- Associated examination
- Pupils and motility
Morphological description
Record onset, laterality, constant or fluctuating course and visual-axis obstruction.
Causes and diagnostic direction
Mechanisms may be aponeurotic, muscular, neurogenic, mechanical or traumatic.
Differential diagnoses
Distinguish true ptosis from redundant skin or an abnormal globe position.
Pitfalls and limitations
A normal pupil does not exclude all neurological causes; a photograph cannot test fatigability.
Take-home message
Describe the eyelid, then integrate pupils, motility and chronology before drawing conclusions.
