Protanopia



Protanopia Causes


Protanopia is a congenital color vision deficiencies. It is caused by an unequal recombination in the gene array passed on from the parents to their children. Patients with protanopia, or protans, either have faulty long-wavelength cones (L-cones) or missing the L-cones altogether. The latter is called protanopia or sometimes red-dichromacy.


Protanopia Definition


Protanopia is also known as Red-Green Color Blindness. Red-green color blindness is split into two different types: People with protan color blindness are less sensitive to red light, and those with deuteranopia or deuteranomly (the second type of red-green color blindness) related to sensitiveness on green light. Males are more prone to this disorder.


Protanopia Diagnosis


Physicians will take a complete medical history and will let the patient undergo a color-blind test.


Protanopia Symptoms and Signs


Patients with this disorder have difficulties in distinguishing between blue and green colors as well as between red and green colors. When comparing the two spectrums you can see that there are different colors and shades of colors that are hard to distinguish for a protanopic person. So those persons are not only blind on red and green colors but also a lot more.


Protanopia Treatment


Because this disorder is congenital, or inborn, there is no treatment available.
