Congenital heterochromia of the iris
- Melanocytosis of the eye.
- Eye-skin melanocytosis.
- Sectoral hamartoma of the iris.
- Congenital Horner's syndrome (ipsilateral hypopigmentation, miosis and ptosis).
- The syndrome of Waardenburg:
- autosomal dominant form I - telecanthus, protruding root of the nose, partial albinism (white locks of hair), deafness; the locus of the gene - on the chromosome 2q37.3;
- autosomal dominant form II - analogous to form I manifestations, accompanied by malformations of the face; the locus of the gene is on the chromosome section of Sp12-p14.
- Sectoral heterochromy of the iris can be associated with Hirschsprung disease.
- Pathological changes in the iris, characterized by focal pigmentation, heterogeneous in its structure; ectropion.
