Heterochromia.
Lui F, Stokkermans TJ. Lui F, et al. 2023 Jun 25. In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2024 Jan–. 2023 Jun 25. In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2024 Jan–. PMID: 34662013 Free Books & Documents.
Heterochromia or heterochromia iridum indicates a difference between the color of the two irises. It can involve the whole iris or only part of the iris (sectoral heterochromia). It is easier to understand the determinants of iris color with the anatomy of th …
