4) Sectoral Heterochromia
Sectoral heterochromia is a hereditary ocular anomaly that can manifest in either one or both eyes, characterized by the presence of two irises with differing colors. The precise etiology of this condition is still unknown, but it is speculated to have genetic origins or be associated with an undisclosed medical concern. Heterochromia, as its name suggests, pertains to the contrast in hue between the iris and the surrounding tissue.
