Green laser induced foveal cyst sustained in a recreational laser light show

We report the case of a 9-year-old boy complained of visual loss in his right eye after watching green laser light show being hit by a ray of a laser at shopping center before five days ago. The laser had a maximum power rating of 30 mW (US Food and Drug Administration class IIIB). Best-corrected visual acuity in his right eye was 0.2 with Snellen at 5 days after the injury. Dilated fundoscopic examination demonstrated a macular hole appearance in the right eye. Spectral domain optical coherence tomography (OCT, Spectralis, Heidelberg Engineering, Heidelberg, Germany) demonstrates a steep fovea contour, a thickening of the macular edges, intraretinal cysts, disruption of the photoreceptor inner segment/outer segment layer and macular pseudohole formation. Central foveal thickness (515 ae m) was increased. Two months after the injury, the patient's visual acuity improved to 0.9 in the right eye without any ocular treatment. Spectral domain OCT revealed the closure of the macular hole with the resolution of the cystic spaces. At 6-months follow-up, visual function had fully recovered and macular assessment was normal.
