Supraoptic recess

Dr Francis Deng and sush et al.

The supraoptic recess, also known as the optic recess or chiasmatic recess, is a small angular recess or diverticulum that sits at the junction of the floor and anterior wall of the third ventricle, immediately above the optic chiasm.

Related pathology

When the third ventricle is expanded due to hydrocephalus (e.g. aqueduct stenosis) this recess, along with the infundibular recess and pineal recess, 'balloons out'.
