Article: Permanent grounding of a USAF pilot following photorefractive keratectomy.
[show abstract] [hide abstract]
ABSTRACT: Photorefractive keratectomy (PRK) has been extensively studied in the literature and its potential application in aircrew has not gone unnoticed. Complication rates following corneal refractive surgery (CRS), including PRK and laser in-situ keratomileusis (LASIK), remain low, with most patients achieving improved uncorrected visual acuity and reduced spectacle dependence. Overall, predictability, low complication rates, high rate of success, stability, and safety have all been cited as instrumental in the adoption of PRK in aviators. Consequently, the U.S. Air Force (USAF) approved PRK for aviators in August 2000. However, quality of vision outcomes following CRS remain a concern given the unique visual performance requirements in military aircrew, especially in austere operational environments. This paper will present a recent case of steroid-induced ocular hypertension that is believed to have precipitated non-arteritic anterior ischemic optic neuropathy (NA-AION) associated with reduced visual performance following PRK that resulted in the first permanent grounding of a USAF pilot following CRS. CRS has radically widened the aircrew applicant pool and has decreased spectacle dependence in war-fighters. Despite the low-risk profile of modern CRS, this case demonstrates the potential for poor outcomes from such elective surgery. Understanding these rare, but potentially devastating complications and the unique aeromedical risk factors in aircrew is paramount when considering elective vision-enhancing surgery.Aviation Space and Environmental Medicine 11/2010; 81(11):1041-4. · 0.88 Impact Factor -
Article: United States Air Force School of Aerospace Medicine Laser Injury Guidebook
[show abstract] [hide abstract]
ABSTRACT: The primary purpose of the laser injury guidebook is to provide guidelines and instructions for flight surgeons dealing with potential laser beam exposures in aircrew and ground personnel. The intent is to provide an evaluation and initial management process to assess and respond to laser beam exposures where ocular and ocular adnexal injury may have occurred. Subjects covered in detail include the laser beam exposure threat in the HR aviation environment, and the role of the flight surgeon in the management of laser beam exposures. Specifically, history, external examination, near visual acuity testing, far visual acuity testing, Amsler grid testing, pupils evaluation, streoposis evaluation, color vision, slit lamp, dilation fundoscopy and vitreoretinal hemorrhage are covered in detail. A point of contact list is provided as well as a suggest list of supplies and equipment. A laser beam incident questionnaire is included, as well as an Amsler grid test, laser injury brief and general flow chart.09/2008; -
Article: Color Vision Issues In Modern Military Aviation
[show abstract] [hide abstract]
ABSTRACT: Visual information provided to the modern military aircrew member accounts for the preponderance of data contributing to situational awareness Although long recognized as a critical factor in aviation, as a result of advancing technological developments, color vision is emerging as an ever-increasing critical requirement in modern and future cockpits Despite that premise, the modern battlefield is characterized by a vast array of technological weaponry that increases the threat to the visual system and dictates effective countermeasures that compromise visual performance in general and color perception in specific. This paper will review the aeromedical basis of color testing developments and issues that effect aeromedical decisions in color standards and performance as they relate to the modern military aircrew member, It will include an update on color vision issues raised by protective equipment such as selective waveband filters that include sunglass materials and laser protective eyewear/visors. Color-related aircraft accident issues will be addressed.03/1994;
