Abstract:

BACKGROUND: Light emitting diodes laser is emerging as an important source of light replacing conventional lights. It is widely used for illumination in the bar where young people love to go. But not everyone knows about the light damage to the eye especially to the macula. In this article, we report the case of a macular damage induced by LED-derived blue laser in a bar, studied with optical coherence tomography (OCT) to evaluate the retinal lesion and multifocal electroretinography (mfERG) to evaluate functional damage.

CASE PRESENTATION: Four days after the photo injury to the right eye, the visual acuity was 0.5. Funduscopy revealed a round red lesion in the macula of the right eye. Fluorescein angiography (FA) revealed no leakage. OCT revealed a deficiency in the center of the fovea. MfERG revealed a reduction of the peak value in the right eye compared to the left eye. One month later, although the vision was 1.0 in the right eye, OCT revealed a hyporeflectivity of the ellipsoid zone. MfERG still showed a reduction of the peak value in the right eye compared to the left eye.

CONCLUSION: We believe that general knowledge about laser injuries to the eye should be realized widely. We also think in cases of macular laser damage, the recovery of vision can not demonstrate the recovery of the function of photoreceptors.
