  • Abstract
  • Look Inside

A 45-year-old male engineer suffered an accidental laser exposure in his right eye. The laser was a continu-ous-wave 810nm diode laser with the power output of 1.5W. He noted central scotoma immediately after the exposure. When seen by us 2 days later, the right visual acuity was 1.2. Funduscopy showed a small white spot with halo in the foveola. Fluorescein and indocyanine green angiography showed dye leakage in the affected area. Optical coherence tomography (OCT) showed a highly refractile focal area extending from the Henle layer to the choriocapillaris, suggesting a thermal damage. OCT was also useful in elucidating the discrepancy between the retinal injury and visual acuity.
