| Popis: |
In this investigation, we have examined the effect of near infrared intense macular laser exposure on the non-human primate focal ERG spectral sensitivity function. Five cynomol-ogous monkeys were exposed to two parafoveal Q-switched Neodymium (1064 nm) laser pulses at approximately 4 millijoules Total Interocular Energy (TIE). Exposures varied in degree of overlap through the superior portion of the fovea. Focal ERG spectral sensitivity measurements were made in the foveal region using a synchronous detection technique. Alteration in the long wavelength region of the focal ERG spectral sensitivity function was observed in all animals, possibly indicative of a more dominant presence of the long wavelength primate cone system resulting from neural disinhibitory effects of damaged photoreceptors as well as the complications of retinal fibrosis on normal receptor activity, orientation and normal retinal receptor reparative functions. |
