Photic maculopathy, a retinal injury, can occur after pterygium removal surgery. Surgeons should limit intense light exposure to the macula during ocular procedures to prevent vision damage.

Area of Science:

  • Ophthalmology
  • Ophthalmic Surgery

Background:

  • Pterygium removal is a common ophthalmic surgical procedure.
  • Prolonged exposure to intense light during surgery is a potential risk factor for retinal damage.

Observation:

  • A 27-year-old woman developed a paracentral scotoma post-pterygium removal.
  • A fluorescein angiogram confirmed a phototoxic macular lesion.

Findings:

  • The patient's symptoms and angiographic findings indicate photic maculopathy.
  • The condition was linked to approximately 40 minutes of retinal exposure during surgery.

Implications:

  • Ophthalmologists must be aware of the risk of photic maculopathy after pterygium removal.
  • Minimizing prolonged, intense coaxial illumination of the retina is crucial during ocular microsurgery to prevent vision loss.
