247 Possible Causes for Dyschromatopsia

  • Autosomal Recessive Progressive External Ophthalmoplegia

    Leber optic atrophy Dyschromatopsia Severe visual impairment Central scotoma Peripheral neuropathy Abnormality of color vision Visual field defect Scotoma Horizontal nystagmus[] Polyhydramnios Respiratory insufficiency Generalized hypotonia Abnormal amplitude of pattern reversal visual evoked potentials Centrocecal scotoma Tritanomaly Red-green dyschromatopsia[]

  • Leber's Hereditary Optic Neuropathy

    […] pathogenic mtDNA point mutations (nucleotide positions 11,778, 3460, and 14,484), usually manifests itself acutely in young adulthood with a stereotypical presentation of dyschromatopsia[] BACKGROUND: Leber's hereditary optic neuropathy (LHON) is a bilateral optic neuropathy of mitochondrial inheritance that produces significant painless, central vision loss and dyschromatopsia[] The authors also characterized the therapeutic potential of idebenone in protecting patients from developing dyschromatopsia in LHON.[]

  • Retrobulbar Neuritis

    It is usually associated with sudden onset loss of vision with dyschromatopsia and retro-orbital pain.[] An Ishihara colour chart and/or Farnsworth-Munsell hue tests are often used to evaluate the degree of dyschromatopsia.[] Kollner's rule states that red/green dyschromatopsia indicates optic nerve or posterior visual pathway disease and blue/yellow or blue dyschromatopsia indicates retinal disease[]

  • Autosomal Dominant Optic Atrophy

    Color vision testing revealed generalized dyschromatopsia. Both visual acuity and color vision deteriorated with age.[] These patients typically present in the first decade of life with slightly subnormal acuity, dyschromatopsia, central visual field loss, and optic disc pallor.[] It is a childhood onset disorder typically characterized by a progressive loss in central vision, color vision deficits (dyschromatopsia), decreased visual acuity, decreased[]

  • Achromatopsia

    In general, symptoms of incomplete achromatopsia (dyschromatopsia) are similar to those of complete achromatopsia except in a diminished form.[] The syndrome is also present in an incomplete form which is more properly defined as dyschromatopsia.[] Iris operating abnormalities The syndrome of achromatopsia/dyschromatopsia is poorly described in current medical and neuro-ophthalmological texts.[]

  • Classic Autosomal Dominant Optic Atrophy

    DOA101 23 0.4/0.3 -6.5/-7.0 Dyschromatopsia, tritan axis Normal outer boundaries, relative central scotoma Temporal pallor Borderline subnormal DOA102 52 0.7/0.9 -3.5/-4.25[] […] third decade of life onward. [1] This patient had a subacute decrease in visual acuity, diffusely depressed visual fields, severe diffuse bilateral RNFL loss, symmetric dyschromatopsia[] […] dominant inheritance - Insensitivity to pain - Optic nerve anomaly / optic atrophy / anomaly of the papilla - Sensorineural deafness / hearing loss Frequent - Achromatopsia / dyschromatopsia[]

  • Optic Neuropathy

    Pupillary reflexes were sluggish and severe dyschromatopsia was documented in both eyes (Ishihara plates).[] Dyschromatopsia can be the initial symptom in toxic/nutritional optic neuropathies.[] Dyschromatopsia (earliest feature): Blue-yellow defects, more commonly than red-green defects, may be the initial presentation. 2.[]

  • Cone Rod Dystrophy 10

    These features are typically followed by impaired color vision (dyschromatopsia), blind spots (scotomas) in the center of the visual field, and partial side (peripheral) vision[] Common initial symptoms are decreased visual acuity, dyschromatopsia, and photophobia which are often noted in the first decade of life.[]

  • Optic Neuritis

    An Ishihara colour chart and/or Farnsworth-Munsell hue tests are often used to evaluate the degree of dyschromatopsia.[] Additionally, dyschromatopsia , photopsia and visual field defects may also occur 1 .[] […] are: vision loss in one eye, which can vary from mild to severe and lasts for 7 to 10 days periocular pain, or pain around your eye that’s often worsened by eye movements dyschromatopsia[]

  • Toxic Retinopathy

    Dyschromatopsia can be the initial symptom in toxic/nutritional optic neuropathies.[] .  Symptoms of toxicity include decreased vision and dyschromatopsia.  Macular pigmentary changes can develop into a "salt-andpepper" pattern.  Long-term use can cause[] Patients may be asymptomatic at onset but may complain of decreased vision and dyschromatopsia.[]
