Which structure represents the second strongest attachment of the vitreous to the retina?

• A. Posterior lens
• B. Vitreous base
• C. Optic disc
• D. Macula

Answer: (A)

The vitreous isn’t equally attached all around the retina; its attachments are concentrated at a few key sites. The firmest connection is at the vitreous base, which hugs the retina near the ora serrata. After that, the next strongest adhesions are at the optic disc (the nerve head) and, to a somewhat similar extent, the macula, where the vitreous cortex adheres tightly to the neural retina. The posterior lens, while it forms part of the interface between the vitreous and the lens via the ligamentous connections, is not a site of vitreoretinal adhesion. So it doesn’t count as a strong attachment to the retina. Therefore, the structure that represents the second strongest vitreoretinal attachment is the optic disc, given its robust vitreous adherence around the nerve head. The macula is also a notable adhesion site, but generally the optic disc is regarded as the next strongest after the base.
