Een hangend ooglid; diagnostiek op basis van een algoritme

– Five patients presented with eyelid drooping (blepharoptosis). A 26-year-old man with oculomotor disorders without anisocoria and a slow progressive course without fluctuations had a myogenic condition. His diplopia was alleviated by prism glasses. Surgical correction of the ptosis was planned. An 81-year-old man in whom the symptoms showed a course that varied over time had a disordered neuromuscular transmission that responded well to pyridostigmine. A 57-year-old man with oculomotor disorders and a dilated pupil on the affected side had an injury to the oculomotor nerve (and other cranial nerves), which remained stable after endovascular treatment of the causative aneurysm. A 22-year-old man had a constricted pupil (Horner's syndrome) and pain in the head and neck due to dissection of the internal carotid; his symptoms disappeared spontaneously. A 34-year-old woman had an isolated ptosis due to detachment of the aponeurosis of the M. levator palpebrae superioris following the chronic use of hard contact lenses; she was advised as to how to remove the lenses cautiously, to prevent further detachment. Eyelid drooping can have many causes. A systematic arrangement of the information gathered by a careful medical history and neurological examination often provides a reasonably accurate indication of the possible causes of the complaints.
