Ocular albinism is the type of albinism that affects only the eyes, specifically the cornea and the retina. People with ocular albinism have uniform skin and hair color, however, their eyes are very hot and the eyelashes are usually white. Oculocutaneous Albinism is typically inherited in an autosomal recessive fashion and is characterized by decreased melanin and subnormal vision since birth. Findings on exam include hypopigmentation of the skin, hair, and irides with diffuse iris transillumination defects on. Ocular albinism is a genetic condition that primarily affects the eyes. This condition reduces the coloring pigmentation of the iris, which is the colored part of the eye, and the retina, which is the light-sensitive tissue at the back of the eye.

Human albinism can be divided broadly into two types, oculocutaneous albinism OCA and ocular albinism OA, where “oculo” means eye and cutaneous means skin. These terms were devised in the late 1940s, when medical science was less sophisticated than it is now.

People who have ocular albinism are born with it. In most cases, it happens because of a problem with a gene they inherit from their mothers. Women carry this gene but don’t usually have symptoms. Ocular albinism is inherited as an X-linked recessive genetic condition. X-linked recessive genetic disorders are conditions caused by an abnormal gene on the X chromosome. Females have two X chromosomes but one of the X chromosomes is “turned off” and most of. People with albinism also have an underdeveloped fovea. The fovea is the part of the retina responsible for much of visual acuity. This is usually the abnormality that most affects vision in ocular albinism and oculocutaneous albinism. Depending on the degree of foveal underdevelopment, vision may be mildly or severely impaired. Ocular albinism, type 2 OA2 CACNA1F: Also known as Forsius-Eriksson syndrome or "Åland Island eye disease", mostly affects males, though females are often carriers and can sometimes be symptomatic; it is frequently linked with protanopic dichromacy a form of color blindness and with night blindness.
