aniridia = irid (opaque) = an + irid + ia
The suffix '-ia' indicates a condition, but the specific medical meaning is not transparent to learners without specialized knowledge.
Etymology
Aniridia comes from Greek parts a- 'not' and iris 'rainbow' or 'the colored part of the eye'. So aniridia means 'without an iris', which explains the missing colored ring in the eye.
