Retinal response of Macaca mulatta to picosecond laser pulses of varying energy and spot size by Roach, William P., Cain, Clarence P., Narayan, Drew G., Noojin, Gary D., Boppart, Stephen A., Birngruber, Reginald, Fujimoto, James G., Toth, Cynthia A.

“…We investigate the relationship between the laser beam at the retina (spot size) and the extent of retinal injury from single ultrashort laser pulses. From previous studies it is believed that the retinal effect of single 3-ps laser pulses should vary in extent and location, depending on the occurrence of laser-induced breakdown (LIB) at the site of laser delivery. …”
