An 83-year-old man presented with complaints of headache and gradual droopiness of the eyes for the past 8-9 months, which worsened in the evening as shown above. There was no history of systemic illness except general body aches. Examination revealed 6/6 visual acuity bilaterally, full extraocular movements, and the anterior and posterior segment was within normal limits. Ptosis parameters were as follows: Right Eye Left Eye Palpebral fissure height (PFH)    7.5 mm 3 mm Levator action    16 mm 14 mm MRD (1)    1.5-2.0 mm -1 mm

1.	The clinical diagnosis is:
	a -- aponeurotic ptosis
2.	The ptosis is:
	b -- bilateral
3.	Treatment is:
	a -- bilateral levator resection

High lid crease and good levator function suggest aponeurotic ptosis. Full extraocular movements rule out CPEO, which starts with asymmetrical extraocular muscle movement restriction. Due to constant use of the frontalis muscle, the patient feels headache towards evening. The patient has bilateral ptosis, but right side ptosis is masked by frontalis overaction. The treatment in this case would be left followed by right levator resection, though right side can be planned later when the patient wants.
