Summary

Patients with arterial hypertension exhibit impaired color vision, even with normal eye exams. This finding is crucial for accurate color vision testing in clinical practice.

Area of Science:

  • Ophthalmology
  • Cardiology
  • Visual Neuroscience

Context:

  • Arterial hypertension is a widespread condition associated with vascular impairments.
  • Assessing end-organ damage in hypertension is standard, but subclinical effects on vision are less understood.
  • Color perception is a sensitive indicator of neural and vascular health.

Purpose:

  • To investigate color perception in patients with arterial hypertension.
  • To determine if arterial hypertension, without evident end-organ damage, affects color vision.
  • To compare color vision performance between hypertensive patients and a healthy control group.

Summary:

  • A study included 35 patients with arterial hypertension and 62 healthy controls, excluding those with other systemic or ophthalmological diseases.

  • Standard ophthalmological examinations were normal in both groups.
  • Hypertensive patients demonstrated significantly poorer performance on the Roth 28-hue color arrangement test compared to controls (p < 0.001).

    • Impact:

    • Disturbed color vision can occur in arterial hypertension even when standard eye examinations are normal.
    • These findings highlight the need to consider hypertension's impact on color vision during diagnostic testing.
    • This research may help differentiate visual disturbances caused by arterial hypertension from those of primary ocular diseases like glaucoma.
