Final answer:
The remnant of the fetal hyaloid artery is involved in the formation of cataracts.
Step-by-step explanation:
The statement in the question is true. The remnant of the fetal hyaloid artery is involved in the formation of cataracts. The fetal hyaloid artery is a blood vessel that supplies nutrients to the lens of the eye during fetal development. If this remnant does not fully regress after birth, it can lead to the formation of cataracts.
