monochromacy

Rod monochromacy, or maskun, is the more common of the two.

One of them carried a gene for rod monochromacy.

Rod monochromacy is the condition of having only rods in the retina.

Achromatopsia has also been called rod monochromacy and total congenital color blindness.

There are two known types of monochromacy.

Both rod and cone monochromacy occur as very rare forms of color blindness in humans.

Cone monochromacy can also be a result of having more than one type of dichromatic color blindness.

People who have, for instance, both protanopia and tritanopia are considered to have cone monochromacy.

Rod monochromacy (achromatopsia): The retina has no cone cells.

Organisms with monochromacy are called monochromats.

Christopher has blue cone monochromacy.

This is called monochromacy.

Cone monochromacy: The retina has both rods and cones, but only one type kind of cone.

In humans, who have three different types of cones, there are three differing forms of cone monochromacy.

Julien Shaft has dextrocardia and monochromacy.

Cone monochromacy is a rare total color blindness that is accompanied by relatively normal vision, electroretinogram, and electrooculogram.

Blue Cone Monochromacy; low vision acuity, color blindness, photophobia, infantile nystagmus.

Dr. Haegerstrom-Portnoy said that by studying rod monochromacy researchers can focus on half of the visual system without the intervening complexity of the other.

Inherited: There are three types of inherited or congenital color vision deficiencies: monochromacy, dichromacy, and anomalous trichromacy.

Since cone monochromacy is the lack of/damage of more than one cone in retinal environment, having two types of dichromacy would be an equivalent.

Blue cone monochromacy (X chromosome) is caused by a complete absence of L and M cones (red and green).

Rod monochromacy (achromatopsia) is an exceedingly rare, nonprogressive inability to distinguish any colors as a result of absent or nonfunctioning retinal cones.

Cone monochromacy, type II, if its existence were established, would be the case in which the retina contains no rods, and only a single type of cone.

Debra O'Bayley of Santa Rosa, Calif., whose 3-year-old daughter Elise, suffers from rod monochromacy, said the child will do anything to stay up late.

Rod monochromacy, frequently called achromatopsia, where the retina contains no cone cells, so that in addition to the absence of color discrimination, vision in lights of normal intensity is difficult.
