Lesions in the occipital lobe commonly cause quadrantanopia (visual field defects). Parietal lobe lesions causing quadrantanopia often present with additional neurological signs.

Area of Science:

  • Neuro-ophthalmology
  • Neuroscience
  • Medical imaging

Background:

  • Optic radiation lesions can cause quadrantanopia due to the geniculocalcarine tract's organization.
  • Understanding the precise localization of visual field defects is crucial for diagnosis.

Purpose of the Study:

  • To identify the specific brain regions associated with quadrantic visual field defects.
  • To correlate lesion location with the type of quadrantanopia observed.

Main Methods:

  • Retrospective analysis of 71 patients with quadrantanopia (41 inferior, 30 superior).
  • Neuroimaging techniques were used to identify the location of the responsible lesions.
  • Data were collected from a neuro-ophthalmology referral practice.

Main Results:

  • Cerebrovascular disorders were the most frequent cause of lesions.
  • Inferior quadrantanopia was primarily associated with occipital lobe lesions (76%), followed by parietal (22%) and temporal (2%).
  • Superior quadrantanopia was predominantly linked to occipital (83%) and temporal (13%) lobe lesions, with parietal lobe involvement (3%) being less common.

Conclusions:

  • Isolated quadrantanopia typically indicates an occipital lobe lesion.
  • Superior quadrantanopia may also involve the temporal lobe, which is difficult to distinguish clinically.
  • Parietal lobe lesions causing quadrantanopia are usually accompanied by other neurological deficits.
