Summary

Accidental exposure to handheld green lasers can cause Laser-Induced Maculopathy (HLIM), leading to vision loss. This case highlights characteristic retinal lesions and the importance of recognizing this injury pattern.

Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Toxicology

Background:

  • Handheld lasers pose a risk of ocular injury.
  • Laser-Induced Maculopathy (LIM) is a recognized condition.

Purpose of the Study:

  • To report a case of accidental self-inflicted handheld Laser-Induced Maculopathy (HLIM).

Main Methods:

  • Observational case report.
  • Clinical examination and ocular imaging (OCT, OCT angiography).

Main Results:

  • A 31-year-old male experienced sudden vision loss in both eyes after green laser exposure.
  • Fundus examination revealed dendritic lesions involving the macula.
  • OCT showed outer retinal layer disruption and OCT angiography indicated choroidal ischemia.

Conclusions:

  • Handheld lasers can cause direct photothermal retinal and choroidal injury.
  • HLIM presents with characteristic plaque-like macular lesions and radiating extensions.
  • Awareness of HLIM and its imaging features is crucial for diagnosis and management.
