Photoreceptor translocation after retinal detachment surgery is rare. Most patients undergoing simple buckling operations have correct reattachment, with minimal spatial distortion, if any.

Area of Science:

  • Ophthalmology
  • Retinal Surgery
  • Visual Neuroscience

Background:

  • Spatial distortions are sometimes reported after complicated retinal detachment surgery.
  • This may stem from photoreceptor translocation during reattachment to the pigment epithelium.
  • The study investigates photoreceptor translocation extent after simple radial buckling procedures.

Observation:

  • Binocular retinal correspondence was measured using a mirror haploscope.
  • Measurements were taken in the peripheral visual field (5, 10, 20 degrees).
  • Participants included normal observers, a complex retinal detachment patient, and 23 simple buckling surgery patients.

Findings:

  • A complex detachment patient showed significant correspondence shift.
  • Among simple buckling patients, 10 maintained fixation; 2 exhibited peripheral correspondence distortions.

  • Only one patient reported subjective spatial distortion post-surgery.

    • Implications:

    • Radial buckle operations generally result in correct photoreceptor reattachment.
    • Minor vertical/horizontal photoreceptor translocations (1-2 degrees) can occur but rarely cause metamorphopsia.
    • This suggests simple buckling is effective with a low risk of significant visual distortion.
