heterochromia

Difference in colour of the two irides or of different parts of the same iris. It is usually congenital but some cases are associated with some eye diseases such as cataract, corneal precipitates, glaucoma, iridocyclitis, iris melanoma or as a result of siderosis. Syn. anisochromia. See Fuchs' syndrome; Horner's syndrome; Marfan's syndrome.

Laboratory findings in iron deficiency Complete blood count: RDW>14 RBC: low Hb, Hct: low according to age and gender MCV: low according to age and gender When specifying the lower limit of MCV: 70+age (for >10 years) (if MCV is <72, generally abnormal) Upper limit of MCV: 84 + age x 0,6 (for >6 months) (if MCV>98: always abnormal) MCH<27 pg MCHC<30% Thrombocytosis Rarely: Thrombocytopenia, leukopenia Peripheral smear: Hypochromia Microcytosis Anisochromia Anisocytosis Pencil cells Rarely: bazophilic stippling, target cells, hypersegmented neutrophils Serum ferritin<12 ng/mL (a) Serum iron: <30 mcg/dL (a) TIBC>480 mcg/dL Transferrin saturation (Iron/TBCx100)<16% Metzner index (MCV/RBC)<13 (a) May change by age, gender and other factors.
The specimen injected with a solution of 1.7 mL/kg iron oxide (Figure 6(c)) preserves the architecture, tubular cells with moderate anisokaryosis, and anisochromia with formation of chromocenters, moderate granulovacuolar cytoplasmic degeneration with focal clear cells, and moderate vascular congestion (HE, 400x).
Nonspecific red blood cell abnormalities can be present, such as anisocytosis, poikilocytosis, anisochromia, basophilic stippling, schistocytes, and erythrocytes that are poorly hemoglobinized.
