ISSN Oculocutaneus albinism is a pigment-related inherited disorder characterized by hypopigmentation of the skin, hair and eyes, foveal hypoplasia and low vision. To date, mutations in the TYR gene have been reported as responsible for oculocutaneus albinism type 1 worldwide. TYR gene encodes the enzyme tyrosinase involved in the metabolic pathway of melanin synthesis. Mutations were identified in the TYR gene as responsible for oculocutaneous albinism type 1 in five Colombian individuals, and a new ophthalmic system was tested that corrected visual defects and symptoms in a patient with oculocutaneous albinism. Materials and methods.

OCA1-MP is characterized by only a minimal activity of tyrosinase, leading to blond hair and white skin and an accumulation of ocular pigment that increases with age. Affected individuals show no skin or eye pigmentation and have white hair and blue irides at birth followed by minimal amounts of pigment that develop in the iris during the first decade of life. Skin nevi may be present. The mutation leads to a minimally active tyrosinase enzyme polypeptide.
