Laser pointer injury findings remain stable following acute damage, whereas genetic retinal diseases are characterized by bilaterality and slow progression. High-resolution optical coherence tomography OCT demonstrated morphological retinal changes such as focal loss or disruption of retinal layers 8 , 9 , 11 , 17 , 18 , 21 , 22 , macular holes 12 , 13 , 23 , 24 , 26 , and cystoid changes or thickening 12 , 17 , 19 in all patients. Although anatomical changes to the inner retinal layers normalized to a large extent during the course of follow-up, lesions in the outer retina and retinal pigment epithelium persisted in all children Figure. All children and adolescents five boys, two girls reported receiving a laser pointer beam in the eyes while playing and, at initial presentation, described disturbing central visual field deficits in the affected eye, which occurred immediately following laser exposure. Berufsgenossenschaft der Feinmechanik und Elektrotechnik: A total of cases were documented average: OCT revealed persistent retinal defects; no cases of full recovery have been described as of yet.

Retinal damage induced by mirror-reflected light from a laser pointer. Bilateral macular hole from a handheld laser pointer. Pediatrics ; ; pii: Shedding some light on laser pointer eye injuries. The objective of the article is to draw attention to the potential hazard posed by laser pointers and to raise awareness of these dangers among children and adolescents in particular.

The spectrum of damage ranged from focal photoreceptor defects to macular foramina and retinal hemorrhages associated with loss of visual acuity and central scotoma. JAMA Ophthalmol ; Ophthalmology Pediatrics and Neonatology.

Retinal Injury Following Laser Pointer Exposure (references)

Even in the case of insufficient patient history, laser pointer injuries can be differentiated from genetic retinal diseases using multimodal imaging rather than genetic diagnostic testing. Assessment of alleged retinal laser injuries.

Georg Spital and Dr. The frequency of these injuries points to the ease with which even high-powered laser pointers can be obtained, their frequent misrepresentation as a toy, and the lack of awareness about the hazards they pose.

Retinal Injury Following Laser Pointer Exposure

Accidental laser injury to the eye. Recent years have seen a marked increase in laser-pointer-related injuries, which sometimes involve severe retinal damage and irreversible visual impairment.

Luttrull Lasersgrahlung, Hallisey J: Ajudua S, Mello MJ: However, only part of the population can be expected to have this blink reflex, meaning that these natural protective mechanisms are inadequate 3. Selbst verursachte laserinduzierte Makulopathie im Jugendalter.

Ophthalmic Genet ; Ophthalmic Surg Lasers Imaging As such, the retinal pigment epithelium lasersteahlung assumed to be the site of greatest damage 31 ; however, the vulnerable photoreceptors located lawerstrahlung in its immediate vicinity are also at risk BMJ Case Rep ; pii: Bilateral macular hole from a handheld laser pointer.

Acknowledgments Our sincere thanks go to Dr. Laser pointer glare and retinal injuries caused by laser pointers have increased considerably in recent years and now represent a relevant problem. This is more pronounced in short-wavelength light green laser pointer; wavelength — nm compared with long-wavelength light red laser pointer; wavelength — nm Berufsgenossenschaft der Feinmechanik und Elektrotechnik: The radiant energy absorbed by tissue causes local tissue to lasersgrahlung, which can lead to protein denaturation, loss of cell integrity, and secondary inflammatory reactions.

Retinal injuries from a handheld laser pointer. As far as reported, 26 patients exhibited bilateral, 32 right-sided, and 27 left-sided injury.

Laser-induced photic injury phenocopies macular dystrophy. Hohberger B, Bergua A: Physicians from a variety of disciplines can make lasegstrahlung valuable contribution in this regard. High-power handheld blue laser-induced maculopathy: This depends on laserxtrahlung wavelength, radiation output power, duration of exposure, spot size of the laser, and the localization of damage Laser pointer injury rarely leads to secondary complications.
