| iris neoplasms | Tumours of the iris characterised by increased pigmentation of melanocytes. Iris nevi are composed of proliferated melanocytes and are associated with neurofibromatosis and malignant melanoma of the choroid and ciliary body. Malignant melanoma of the iris often originates from preexisting nevi. (12 Dec 1998) |

| erythema iris | Concentric rings of erythema varying in intensity, characteristic of erythema multiforme. Synonym: herpes iris. (05 Mar 2000) |
| essential progressive atrophy of iris | Progressive atrophy of the iris without inflammatory signs, characterised by patchy loss of all layers of the iris with hole formation, migration of the pupil, degeneration of the corneal endothelium, peripheral anterior synechiae, and secondary glaucoma; usually unilateral, predominantly affecting women in their middle years. (05 Mar 2000) |
| folds of iris | Numerous very fine, almost microscopic, radial folds on the posterior surface of the iris that extend around the pupillary margin. Synonym: plicae iridis. (05 Mar 2000) |

| adrenal hyperplasia, congenital | A group of inherited disorders of adrenal steroidogenesis, the physical expression of which varies with the sex of the patient, the severity of the congenital enzyme defect, and the age at which the defect makes its presence felt. The most common form, the simple virilizing form, is due to a 21-hydroxylase deficiency. There is also a salt-losing form (a more complete 21-hydroxylase deficiency), a hypertensive form (11-hydroxylase deficiency), a 17-hydroxylase deficiency form, a desmolase deficiency form, and a 3-beta-hydroxysteroid deficiency form.

| anaemia, dyserythropoietic, congenital | A familial disorder characterised by anaemia with multinuclear erythroblasts, karyorrhexis, asynchrony of nuclear and cytoplasmic maturation, and various nuclear abnormalities of bone marrow erythrocyte precursors. Type II is the most common of the 3 types of congenital dyserythropoietic anaemia; it is often referred to as hempas, based on the hereditary erythroblast multinuclearity with positive acidified serum test. (12 Dec 1998) |
| anaemia, haemolytic, congenital | Haemolytic anaemia due to various intrinsic defects of the erythrocyte. (12 Dec 1998) |
| anaemia, haemolytic, congenital nonspherocytic | Any one of a group of congenital haemolytic anaemias in which there is no abnormal haemoglobin or spherocytosis and in which there is a defect of glycolysis in the erythrocyte. In some cases, pyruvate kinase deficiency has been demonstrated; in other cases, glucose-6-phosphate dehydrogenase deficiency has been demonstrated. (12 Dec 1998) |
