Which of the following is an embryological remnant of the hyaloid artery on the optic disc?

• A. Epicapsular star
• B. Mittendorf's dot
• C. Bergmeister's papillae
• D. Cloquet's canal

Answer: (C)

During eye development the hyaloid system nourishes the developing lens and retina and then largely regresses, leaving only small remnants. On the optic disc, the proximal portion of this system can persist as Bergmeister's papillae—a tiny tuft of tissue at the disc where the hyaloid artery entered the eye. That is why Bergmeister's papillae is the embryological remnant located on the optic disc.

The other remnants are in different locations: Mittendorf's dot sits on the posterior surface of the lens capsule as the distal end of the hyaloid artery; Cloquet's canal is the central tunnel of vitreous left behind after regression; epicapsular star appears on the anterior lens capsule as remnants of the tunica vasosa lentis.
