Which structure is the weakest attachment among retinal attachments?

• A. Retinal vessels
• B. Macula
• C. Optic disc
• D. Ora serrata

Answer: (A)

The question is about which part of the retina provides the weakest mechanical attachment at the vitreoretinal interface. The retina is anchored to surrounding structures most firmly at areas where strong fibrous or vitreous connections exist, such as near the optic disc and around the macula, and at the ora serrata where the retina meets the ciliary body and the vitreous base. Retinal vessels, by contrast, are merely channels that course through the retinal tissue; their connection to the retina is limited to the vessel walls within the neural layers and does not form a substantial, supportive attachment of the retina to underlying structures. Because they don’t contribute to a strong anchorage, retinal vessels are the weakest attachment among the listed retinal attachments.
