Case Reports
[A girl with dyslexia suspected to have Irlen syndrome, completely relieved by wearing tinted lenses].
Irlen syndrome is a proposed perceptual processing disorder characterized by visual distortions while reading. Patients with this syndrome may experience light sensitivity, visual stress, and other related problems such as dyslexia. Tinted lenses and colored overlays have been designed to help individuals with the symptoms of Irlen syndrome. ⋯ These ambiguous criteria may be responsible for the criticism over the validity of this condition. Although this was only an anecdotal case, our patient exhibited the core functional deficit described in Irlen syndrome and showed a dramatic improvement with tinted lenses; therefore, this case may facilitate investigations into the mechanism underlying Irlen syndrome, if it actually exists. Although further studies are required to confirm the validity of this syndrome and the treatment approach, Irlen syndrome should be recognized as a disorder since its symptoms can be easily relieved by wearing tinted lenses or color filters.
