1 Laser Exposure to Aircrew CAPT Matt Rings Aerospace Ophthalmology

2 Disclosure Statement CAPT Rings has investments in the following companies who manufacture military laser systems: General Dynamics Northrup Grumman Corp Coherent Inc. II-VI inc.

3 Laser Threats Handheld Laser Pointers - (Red/Green/Blue)
CAS lasers (vis/IR) Airborne lasers – targeting and countermeasures (vis/IR) Anti-personnel lasers (Green)

7 Tahrir Square - Egypt

8 Laser Physical Effects
Glare “Dazzle” Flash-blindness Irritation Photophobia Headache & eye pain Sub-clinical tissue damage Visible retina and ocular damage Retinal hemorrhage

9 Laser Aviation Effects
Surprise / Startle effect Distraction Inability to discern instruments and landing lights Mission compromise or failure Loss of aviator temporarily or permanently to flight

12 Ground Incidences “Friendly fire” from ground targeting lasers:
“Since November 2008, [we have] had 64 laser incidents reported in Iraq, resulting in 45 documented injuries to soldiers. Two of those injuries were permanent — one soldier is now legally blind in one eye, Hayes said.” “Usually, the damage is temporary,” he said, “but they have to be evaluated by a retina specialist in the States.” (Stars & Stripes, June 14, 2009)

13 2012 DoD Aviation Incidences
79 Aviation Laser Incidents reported via Hotline 20 HAZREPS Abnormal Eye Exams (~10% rate)

14 USN Aviation Note: Multiple persons per incident is frequent

15 Commercial / Civil Aircraft
2004: 46 incidences 2008: 988 incidences 11% reported distraction, glare, afterimage, ops interference, 2% pain/injury 69% on final approach 92% green lasers, 5% red lasers 7PM to 11PM (70%) The Illumination of Aircraft at Altitude by Laser Beams: A 5-Year Study Period ( FAA

16 Pre-Flight Crew Procedures
OPNAV 3710 : annual LEP / laser training Review reports of any laser activity in the area reported to ATC (concerts, pireps, intel) Consider Laser Eye Protection (LEP) based on theater threat intelligence Discuss in-flight laser exposure procedures Carry small Amsler grid (if significant threat) LEP must be worn if “significant laser threat” exists (per OPNAV U)

17 In-Air Exposure Procedures
Look Away & shield eyes (don LEP if available) DO NOT rub the eyes – increases irritation Turn up instrument lights Mark the position, time, and report to ATC Unexposed co-pilot gets on instruments Query other crew members for exposure Self-examination using small print or Amsler grid (if available) ‘Self-triage’ vision able to read small print, check individual eyes, check pocket Amsler grid, nav charts, HUD or MFD for any visual defects Determine mission viability, if significant vision symptoms prevent safe continuance

18 Crew After-Landing Procedures
Notify Chain of Command Notify Flight Surgeon & Laser Safety System Officer ( per OPNAVINST B) Undergo eye exam by Flight Surgeon as soon as practicable Complete HAZREP Complete FAA laser exposure web report Call DoD Laser Hotline (24/7) Toll-free:

22 Laser Injury Guidebook
United States Air Force School of Aerospace Medicine Laser Injury Guidebook: Appendix C: Laser Incident Questionnaire Appendix D: Amsler grid

23 Flight Surgeon Procedures
Complete the ‘Laser Incident Questionnaire’ (Appendix C of Laser Injury Guidebook) Obtain complete history of events List ocular symptoms Document LEP or eyewear worn (e.g. NVGs)

24 Flight Surgeon Physical Exam
Visual Acuity (with correction) Amsler Grid test Pupil exam Stereopsis testing Color Vision Slit Lamp – corneal abrasions/burns, lens opacity, conjunctival injection.

25 Flight Surgeon Exam and Actions
Dilated Retinal Exam Evaluate for retinal changes, blood, burns, white lesions

26 Ophthalmology Consultation
Does laser eye exam reveal significant visual or ocular findings? If yes, consult ASAP to ophthalmology or aerospace optometrist Navy/USMC: OPNAV : **ALL exposures get consult exam** Make recommendation on Fitness for Aviation Duty or further medical management

27 Laser Exposure Aerospace Pearls
99%+ of exposures will not cause permanent injury– may return to flight if no persistent symptoms, normal vision testing and normal exam. Document follow-up in 1-3 days. Actual injuries or persistent symptoms: “Down” chit for flight pending further workup Ophthalmology/Optometry consult (aerovac as needed) Laser Hotline advice on ALL exposures
