Abstract:

With eye injuries constituting a significant percentage of all combat casualties, proper, definitive ophthalmological care in the far forward field medical system is needed. Our goal is to develop a non-mydriatic ophthalmoscopefundus camera suitable for use under field conditions that will permit acquisition and storage of digital images and rapid assessment of basic visual function. We surveyed the existing ophthalmoscopefundus camera technologies to establish an awareness of the state of the art in this field. Based on the survey results, we consider scanning laser ophthalmoscopy the most suitable technology for the proposed system. The nature and frequency of combat related eye injuries was investigated to determine the desired capabilities of a baseline scanning laser system. The performance envelope of the baseline system was specified based on the military standards for equipment design and environmental requirements. A feasibilitydesign trade-off study was conducted based on the desired capabilities and performance envelope. Software was developed to acquire and store non-mydriatic, digital fundus images with our COTS scanning laser ophthalmoscope and to transmit these over the Internet. Proof-of-concept hardware for implementing basic visual function testing into the COTS scanning laser ophthalmoscope was developed and successfully tested.
