Possible Treatment

10859 — 2015-03-06 20:18:21 UTC

-Currently no treatment for Monochromacy

-working on stimulation of the blue cone

-consists of injection into the retina

-injection has a non-replicated gene to try and change the dominant/recessive roles

Parental Tests -------------- Gene Location

10859 — 2015-03-09 19:02:49 UTC

-There is no genetic tests for monochromacy

-Won't know if child is colorblind until age 4

-gene is located on the X chromosome

Cones

873771 — 2015-03-09 19:37:46 UTC

-Cones: Near the fovea in the eye, is essential for color vision

-Each cone detects a different wavelength (short, medium, long)

-Monochromacy is caused by either a defect or complete absence of the retinal cones

-Monochromacy is when the human retina contains only a single kind of light receptor cell

-When two cone pigments are missing, vision is reduced to black and grey and white

Basic kinds of Monochromacy

873771 — 2015-03-10 17:46:37 UTC

-Rod Monochromacy: Total or complete achromatopsia, total color blindness

- Most common type of complete blindness

- Cone monochromacy: is a rare type of total color blindness, however is accompanied by relatively normal vision.
