- What it is
- A narrow, clear channel running through the vitreous from the optic disc to the back of the lens.
- Function
- The remnant of the path of the fetal hyaloid artery, which nourished the developing lens and normally regresses before birth.
- Size
- About 1-2 mm wide and ~15 mm long, widening towards the lens.
- Clinical note
- Incomplete regression leaves a tiny dot on the back of the lens (Mittendorf dot) or a tag on the disc (Bergmeister papilla).
