Surgical correction of esotropia (inward turning eyes) significantly expands the horizontal peripheral visual field. This visual field expansion occurs irrespective of amblyopia or fusion recovery, suggesting it

Area of Science:

  • Ophthalmology
  • Neuroscience
  • Vision Science

Background:

  • Esotropia, or inward turning of the eyes, can impact visual field extent.
  • Peripheral vision assessment is crucial for understanding the functional consequences of strabismus.

Purpose of the Study:

  • To quantify the horizontal extent of the binocular peripheral visual field in adult esotropes.
  • To evaluate the effect of strabismus surgery on peripheral visual field dimensions.

Main Methods:

  • Goldmann perimetry was utilized to measure the horizontal visual field.
  • Measurements were taken before and after strabismus surgery in ten adult patients.

Main Results:

  • All patients demonstrated an expansion of the horizontal peripheral visual field post-surgery.

  • The degree of visual field expansion correlated with the surgical correction of the strabismic angle.
  • Field expansion was observed irrespective of amblyopia or the recovery of binocular fusion.

    • Conclusions:

    • Surgical correction of esotropia leads to a significant and predictable expansion of the peripheral visual field.
    • Visual field expansion is a notable outcome of esotropia correction, even in the absence of fusion.
    • This finding supports surgical intervention for esotropia, highlighting visual field enhancement as a key benefit.
