Laser and light-based devices can cause serious ocular complications, including corneal abrasions, loss of visual acuity and pupillary abnormalities. Injuries result from direct exposure to electrical current from artificial sources such as household wiring, electrical outlets, appliances, industrial equipment, and overhead power lines as well as natural sources such as lightning. Most commonly affect adolescents aged 13-18 years old. In an effort to identify risk factors and reduce the rate of ocular complications, Margit Juhasz, MD, MSc, Christopher Zachary, MD, and Joel Cohen. Laser energy impacts eye tissues through several distinct mechanisms, primarily depending on the laser's characteristics. This heat can denature proteins, leading to. The human eyes are highly sensitive to the radiation emoted by laser beams and when they are not adequately protected, may sustain damages ranging from minor to severe injuries which can impair vision temporarily or permanently. Threshold and extent of the eye or ocular damage depend on the. 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. Four days after the photo injury to the right.
