Delayed presentation of morning glory disc anomaly and transsphenoidal encephalocele: A management dilemma.

Morning glory disc anomaly (MGDA) is a rare developmental abnormality of the optic disc that is associated with many other neurological and vascular conditions. Most cases are diagnosed in childhood. We report a 57-year-old woman who presented to the ophthalmology department for assessment of long-standing poor vision in the left eye and exotropia.

Enlargement of the nasolacrimal canal in the absence of neoplasia.

Downgaze eyelid position in patients with blepharoptosis.

Purpose: To prospectively examine the change in upper eyelid position on downgaze in patients with blepharoptosis.

Methods: Upper eyelid margin to corneal light reflex distance (uMRD) was measured in primary gaze and in 30 degrees to 40 degrees downgaze in 50 consecutive patients with acquired ptosis and 10 consecutive patients with congenital ptosis.

Results: For the acquired ptosis group, the mean change in uMRD on downgaze was -0.
