Heterochromia is a difference in coloration, usually of the iris but also of hair or skin.
The reduced pigmentation in the eyes was clearly evident from hazel green to light brown and bluish colouration of the iris but no symptom of
heterochromia iridis was observed.
PPM may also be accompanied by persistent hyperplastic tunica vasculosa lentis, persistent hyperplastic primary vitreous, cataract, microphthalmia (BAYON et al., 2002; MITCHELL, 2011), retinal dysplasia (BAYON et al., 2002), iris hypoplasia (MISK et al., 1998; PINARD & BASRUR, 2011),
heterochromia iridis (MISK et al., 1998), angle-closure glaucoma caused by pupillary block, or peripheral anterior synechiae (YOUNG et al., 1974).
Iris
heterochromia, dilation lag, anhidrosis, and harlequin sign may concurrently be present [2, 3].
(2) Waardenburg syndrome: Type I, wide bridge of the nose, lateral displacement of the inner canthus, pigmentary disturbance of frontal white blaze of hair,
heterochromia iridis, white eye lashes, leukoderma, cochlear deafness, and spina bifida.
The various acral RPD include reticulate acropigmentation of Kitamura, acropigmentation of Dohi, acral melanosis and
heterochromia extremitarium.
(5,9,10,11) Accordingly, cases exhibiting typically unilateral, chronic, low-grade anterior chamber reaction with varying degrees of vitreous opacity, widespread small- or medium-sized keratic precipitates (KP) in the corneal epithelium, diffuse iris atrophy and/or
heterochromia but without acute exacerbations, posterior synechiae or cystoid macular edema were clinically diagnosed with FUS.
Iris condition was evaluated and abnormalities like peripheral buttonhole iridectomy, iritis, rubeosis, atrophic patches,
heterochromia, synechiae, nodules were looked for.
There are two kinds of
heterochromia. If it is complete, one iris is a different colour from the other.
[sup][3] considered distinctive ocular symptoms, markedly elevated IOP, acquired iris
heterochromia, and the failure of appropriate treatment as indicating an underlying malignancy to secondary glaucoma.
