An optic pit is usually located on the optic nerve head in which region?

• A. Inferior or temporal region
• B. Superior or nasal region
• C. Central disc
• D. Equatorial region

Answer: (A)

Optic pits are small congenital depressions in the optic nerve head that occur most commonly at the inferior-temporal border of the disc. This inferotemporal location is a classic feature seen on exam and helps distinguish pits from other disc findings. The other regions—superior or nasal, central disc, or equatorial—are not the typical sites for a pit, as the pit characteristically sits near the edge of the disc, usually on the inferior-temporal side. Often, pits can be associated with serous detachment of the macula due to fluid from the pit communicating with subretinal spaces, which is why recognizing this location is clinically important.
