Deuteranomalia is a common form of red-green color vision deficiency. It is a mild anomalous trichromacy where the green cone photopigments are abnormal. Individuals with deuteranomalia have difficulty distinguishing between shades of red, green, and yellow. This condition is not considered a disease and does not typically affect vision quality in other ways, such as visual acuity or visual field.

The underlying cause of deuteranomalia is a genetic mutation on the X chromosome. Since males have only one X chromosome, they are more likely to be affected by X-linked genetic conditions. Females, having two X chromosomes, are less likely to be affected but can be carriers. The condition is inherited, meaning it is passed down from parents to children.

Diagnosis of deuteranomalia is usually made through various color vision tests, such as the Ishihara plates or the Farnsworth-Munsell 100 Hue test. Treatment is generally not required as it does not significantly impact daily life for most individuals. In some professions where color discrimination is critical, such as piloting or certain electrical trades, this condition might pose challenges. However, in everyday life, most people with deuteranomalia adapt without noticing significant limitations.
