Progressive sensorineural hearing impairment- MedGen UID:
- 335894
- •Concept ID:
- C1843156
- •
- Disease or Syndrome
A progressive form of sensorineural hearing impairment.
Cerebellar ataxia- MedGen UID:
- 849
- •Concept ID:
- C0007758
- •
- Disease or Syndrome
Cerebellar ataxia refers to ataxia due to dysfunction of the cerebellum. This causes a variety of elementary neurological deficits including asynergy (lack of coordination between muscles, limbs and joints), dysmetria (lack of ability to judge distances that can lead to under- or overshoot in grasping movements), and dysdiadochokinesia (inability to perform rapid movements requiring antagonizing muscle groups to be switched on and off repeatedly).
Spasticity- MedGen UID:
- 7753
- •Concept ID:
- C0026838
- •
- Sign or Symptom
A motor disorder characterized by a velocity-dependent increase in tonic stretch reflexes with increased muscle tone, exaggerated (hyperexcitable) tendon reflexes.
Peripheral neuropathy- MedGen UID:
- 18386
- •Concept ID:
- C0031117
- •
- Disease or Syndrome
Peripheral neuropathy is a general term for any disorder of the peripheral nervous system. The main clinical features used to classify peripheral neuropathy are distribution, type (mainly demyelinating versus mainly axonal), duration, and course.
Polyneuropathy- MedGen UID:
- 57502
- •Concept ID:
- C0152025
- •
- Disease or Syndrome
A generalized disorder of peripheral nerves.
Abnormal auditory evoked potentials- MedGen UID:
- 141758
- •Concept ID:
- C0522216
- •
- Finding
An abnormality of the auditory evoked potentials, which are used to trace the signal generated by a sound, from the cochlear nerve, through the lateral lemniscus, to the medial geniculate nucleus, and to the cortex.
Gait disturbance- MedGen UID:
- 107895
- •Concept ID:
- C0575081
- •
- Finding
The term gait disturbance can refer to any disruption of the ability to walk.
Abnormal amplitude of pattern reversal visual evoked potentials- MedGen UID:
- 871342
- •Concept ID:
- C4025834
- •
- Finding
Myopathy- MedGen UID:
- 10135
- •Concept ID:
- C0026848
- •
- Disease or Syndrome
A disorder of muscle unrelated to impairment of innervation or neuromuscular junction.
Increased variability in muscle fiber diameter- MedGen UID:
- 336019
- •Concept ID:
- C1843700
- •
- Finding
An abnormally high degree of muscle fiber size variation. This phenotypic feature can be observed upon muscle biopsy.
Ptosis- MedGen UID:
- 2287
- •Concept ID:
- C0005745
- •
- Disease or Syndrome
The upper eyelid margin is positioned 3 mm or more lower than usual and covers the superior portion of the iris (objective); or, the upper lid margin obscures at least part of the pupil (subjective).
Ophthalmoplegia- MedGen UID:
- 45205
- •Concept ID:
- C0029089
- •
- Sign or Symptom
Paralysis of one or more extraocular muscles that are responsible for eye movements.
Optic atrophy- MedGen UID:
- 18180
- •Concept ID:
- C0029124
- •
- Disease or Syndrome
Atrophy of the optic nerve. Optic atrophy results from the death of the retinal ganglion cell axons that comprise the optic nerve and manifesting as a pale optic nerve on fundoscopy.
Strabismus- MedGen UID:
- 21337
- •Concept ID:
- C0038379
- •
- Disease or Syndrome
A misalignment of the eyes so that the visual axes deviate from bifoveal fixation. The classification of strabismus may be based on a number of features including the relative position of the eyes, whether the deviation is latent or manifest, intermittent or constant, concomitant or otherwise and according to the age of onset and the relevance of any associated refractive error.
Central scotoma- MedGen UID:
- 57750
- •Concept ID:
- C0152191
- •
- Finding
An area of depressed vision located at the point of fixation and that interferes with central vision.
Red-green dyschromatopsia- MedGen UID:
- 102324
- •Concept ID:
- C0155016
- •
- Disease or Syndrome
Difficulty with discriminating red and green hues.
Blue color blindness- MedGen UID:
- 57827
- •Concept ID:
- C0155017
- •
- Disease or Syndrome
Tritanopia is an autosomal dominant disorder of human vision characterized by a selective deficiency of blue spectral sensitivity (Weitz et al., 1992).
Reduced visual acuity- MedGen UID:
- 65889
- •Concept ID:
- C0234632
- •
- Finding
Diminished clarity of vision.
Centrocecal scotoma- MedGen UID:
- 82870
- •Concept ID:
- C0271196
- •
- Finding
A scotoma (area of diminished vision within the visual field) located between the central point of fixation and the blind spot with a roughly horizontal oval shape.
Horizontal nystagmus- MedGen UID:
- 124399
- •Concept ID:
- C0271385
- •
- Disease or Syndrome
Nystagmus consisting of horizontal to-and-fro eye movements.
Dyschromatopsia- MedGen UID:
- 163559
- •Concept ID:
- C0858618
- •
- Disease or Syndrome
A form of colorblindness in which only two of the three fundamental colors can be distinguished due to a lack of one of the retinal cone pigments.
Visual impairment- MedGen UID:
- 777085
- •Concept ID:
- C3665347
- •
- Finding
Visual impairment (or vision impairment) is vision loss (of a person) to such a degree as to qualify as an additional support need through a significant limitation of visual capability resulting from either disease, trauma, or congenital or degenerative conditions that cannot be corrected by conventional means, such as refractive correction, medication, or surgery.
