Congenital dyschromia can be detected through genetic testing, i.e. chromosome testing, while acquired dyschromia usually cannot be detected through chromosome testing.
Color deficiency is divided into congenital color deficiency and acquired color deficiency. Most of the genes for congenital color deficiency are located on the X chromosome, and the mode of inheritance is companion inheritance, which can be detected through chromosome testing. Because of genetic defects, the development of cells in the retina that sense color is abnormal, and there is no way to quickly and accurately distinguish the difference between different colors.
Acquired color deficiency can be caused by retinal diseases, drug intoxication and other reasons leading to a decrease in the ability to distinguish colors, which usually cannot be detected through chromosome testing.
If a patient suspects that he or she has color deficiency, he or she should go to the ophthalmology department of a hospital for a timely examination, so that the doctor can confirm the diagnosis and guide the treatment.
