Individuals with diabetic retinopathy and peripheral neuropathy can often still learn to read braille. Two-point discrimination ability is a key indicator for braille reading success in visually impaired diabetic patients.

Area of Science:

  • Neurology
  • Ophthalmology
  • Diabetology

Background:

  • Diabetic retinopathy is a leading cause of visual impairment.
  • Peripheral neuropathy frequently coexists with diabetic retinopathy.
  • The impact of neuropathy on braille reading ability in these patients is not well-defined.

Purpose of the Study:

  • To investigate the relationship between peripheral neuropathy and braille reading ability in individuals with diabetic retinopathy.
  • To assess the utility of two-point discrimination and nerve conduction studies in predicting braille reading success.

Main Methods:

  • Neurologic examination including two-point discrimination and nerve conduction studies.
  • Evaluation of 35 individuals with visual impairment due to diabetic retinopathy.

  • Assessment of braille reading acquisition (standard or jumbo).

    • Main Results:

    • All participants had peripheral neuropathy (stages 1-3).
    • Two-point discrimination was relatively preserved in most individuals.
    • 25 out of 35 participants successfully learned to read braille.
    • Impaired two-point discrimination (greater than 5 mm) correlated with difficulties in braille reading.

    Conclusions:

    • Peripheral neuropathy, common in diabetic retinopathy, does not necessarily preclude braille reading.
    • Two-point discrimination ability is a significant factor in braille reading success.
    • Individuals with visual impairment from diabetes should be encouraged to attempt braille reading despite apparent neuropathy.
