Abstract:

This Redwing project was designed to furnish supplemental information on the requirements for protection against retinal burns using both rabbits and monkeys as experimental animals. Chorioretinal burns were produced by various segments of the thermal pulse. This was accomplished by two series of time- fractionating shutters. The first group, the early closing shutters, were open at time zero and closed at increasing intervals of time. The second series, the delayed-opening shutters, were closed at time zero and subsequently opened for preselected time increments during the flash. The feasibility of protection by fixed-density optical filters was explored. Two types of protective electronic shutters were field tested. Additional objectives were to 1 determine whether blink reflexes would prevent chorioretinal burns 2 ascertain which portions of the time-intensity pulse can produce thermal injury to the retina and choroid of the eye 3 determine the time required for blink reflex in rabbits and monkeys exposed to the extreme light intensity of the nuclear detonations 4 explore the feasibility of ocular protection by means of fixed-density optical filters or combinations of filters and 5 tests, under field conditions, protective shutter devices that are in the developmental state and are designed to close more rapidly than the blink reflex.
