Blue cone (OPN1SW; 613522) monochromatism is a rare X-linked congenital stationary cone dysfunction syndrome characterized by the absence of functional long wavelength-sensitive and medium wavelength-sensitive cones in the retina.

Rod monochromatism (RM) – an absence of all functioning cone photoreceptors with visual perception depending almost exclusively on rods. The rod monochromat has markedly reduced visual acuity and total color blindness. BCM is distinguished from RM via psychophysical and electrophysiological testing. The photopic ERG is profoundly reduced in both, although the S-cone ERG is well preserved in BCM.* Monochromatisme (Médecine) - Définition,rod monochromatism â†' achromatopsie congénital e complète avec amblyopie,( Monochromatisme , Anomalies de la vision , Trouble s de la perception des couleurs),Monochromacy – Complete Color Blindness – Colblindor,20/07/2007· Monochromacy—also referred to as monochromatism—can be observed in different forms and even worse, many different names are in use: rod monochromacy: typical or complete achromatopsia, total color blindness, day blindness blue-cone monochromacy: S-cone monochromacy, incomplete achromatopsia cone,

Abnormality of color vision (Concept Id: C0234629)

Cone-rod dystrophy is a group of related eye disorders that causes vision loss, which becomes more severe over time. These disorders affect the retina, which is the layer of light-sensitive tissue at the back of the eye. In people with cone-rod dystrophy, vision loss occurs as the light-sensing cells of the retina gradually deteriorate.The first signs and symptoms of cone-rod dystrophy, which often occur in* Diurne (Médecine) - Définition - Encyclopédie en ligne,rod monochromatism â†' achromatopsie congénitale complète avec amblyopie... ~ nocturne et déjections - la maladie de Chagas est due à trypanosomiase cruzi (Tc) dont la transmission est assurée par plusieurs espèces de réduves (barbeiros ou 'grosse punaise').

It can impair tasks such as selecting ripe fruit, choosing clothing, and reading traffic lights. Color blindness may make some educational activities more difficult. However, problems are generally minor, and most color-blind people adapt.
