Diagnosing damage from a 1000mv laser pointer
If the answers to all six questions are “yes,” then a 1000mw laser pointer injury has almost certainly occurred. The authors state that “perceived ocular injuries with no demonstrable tissue damage are not real laser injuries.” In their concluding “Comment” section, the authors state that injuries that cause serious visual problems are readily apparent from tests, while injuries that are subtle or ambiguous “should have excellent visual prognoses and clinical outcomes.”

Six Questions That Facilitate the Diagnosis of Alleged Retinal Laser Injuries
The following is from the journal article “Assessment of Alleged Retinal 3000mw laser pointer Injuries”:
Are there ocular abnormalities that could have been caused by a known laser-tissue interaction at the time of the reported incident?
If the answer to 1 is “yes,” have those abnormalities been documented by a reliable technique, such as fundus photography, fluorescein angiography, or optical coherence tomography?
If the answers to 1 and 2 are “yes,” do findings from ophthalmoscopy and retinal imaging evolve after the incident in a manner consistent with a laser injury?
If the answer to 1 is “yes” and substantial visual or somatic complaints are present, is there any scientific evidence that the objective ocular findings could cause the reported subjective complaints?
If the answer to 1 is “yes” and substantial visual complaints are present, is the location of Amsler grid or visual field defects stable and consistent with the location of the retinal abnormalities supposedly responsible for causing them?
If the laser source involved in the alleged injury is available or known, is it capable of producing the observed clinical findings under the reported exposure conditions?
