We report the case of a twenty-year-old man with a unilateral maculopathy responsible for an acute visual acuity loss and a sudden absolute central scotoma. His schizoid personality made the medical history fruitless. The patient's best corrected visual acuity was 20/60. Clinical examination revealed a strictly unilateral maculopathy with pigment remodeling and hyper-autofluorescent areas. Through this case report, we describe the characteristics of the lesion and the pathway to the diagnosis: a laser pointer-induced photic injury.

UI MeSH Term Description Entries
D007834 Lasers An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.

D008266 Macula Lutea An oval area in the retina, 3 to 5 mm in diameter, usually located temporal to the posterior pole of the eye and slightly below the level of the optic disk. It is characterized by the presence of a yellow pigment diffusely permeating the inner layers, contains the fovea centralis in its center, and provides the best phototropic visual acuity. It is devoid of retinal blood vessels, except in its periphery, and receives nourishment from the choriocapillaris of the choroid.
