Abstract

PURPOSE: We report a case of macular injury by accidental exposure to a green laser pointer.
CASE SUMMARY
A 25-year-old man had an acute reduction of visual acuity in his right eye two years ago after accidental exposure to a green laser pointer for a few seconds. The patient's best corrected visual acuity was counting fingers in his right eye. Fundus examination and optical coherence tomography showed a macular hole and a linear retinal scar in his right eye.
CONCLUSIONS
Green laser pointers may cause macular damage after exposure of just a few seconds, which can lead to irreversible reduction of visual acuity.

  Figure 1. Fundus photograph shows 1.5 optic disc diameter-sized parafoveal retinal scar with temporally and superiorly extended linear retinal scars (A). Fluorescein angiography shows hyperfluorescence at the margin of the lesions and hypofluorescence in the lesion on the fovea and parafoveal area with superior and temporal lineal extensions (B).

• 

  Figure 2. Optical coherence tomography shows full‐ thickness macular hole (A) with adjacent detachment and scar formation (B).
