疑似的视网膜激光损伤的诊断

Assessment of alleged retinal laser injuries

Accidental retinal laser injuries a re easily diagnosed when there are known laser sources,typic al macular injuries,and visual deficits consistent with retinal findings.Deci-sions are more difficult when retinal findings are subtle or absent,despite reported visual pro blems and somatic complaints.Inaccurate diagnosis o f an ocular laser injury can precipitate a costly,lengthy se quence of medical and legal problems.Analysis of laser-tissue interactions and the characteristics of unambiguous retinal laser injuries provide6key questions to facilitate diffic ult diagnoses.Case reports demonstrate the usefulness of answering these questions before making diagnostic decisions.Retinal laser lesions that cause serious visual pr oblems are readily ap-parent ophthalmoscopically and angiographically.Acci-dental,intentional,or clinical re tinal laser lesions do not cause chronic eye,face,or head pain s.Diagnosis of a retinal laser injury should be evidence based,not a matter of conjecture or speculation.
