AIM: To explore the effects of laser-activated remote phosphors (LARP) on visual function in guinea pigs. METHODS: Electroretinogram (ERG) of guinea pigs were observed after LARP irradiation at different frequencies and irradiation times. We evaluated the expression of rhodopsin, β-catenin, connexin36, calretinin, and calbindin in the retina of guinea pigs and measured the density of photoreceptor cells after high-frequency LARP irradiation. RESULTS: After LARP irradiation, the ERG results showed that the amplitude of the dark-adapted 3.0 b-wave of the model eye was lower than that of the control eye after high-frequency irradiation (P<0.05). The expression of rhodopsin, β-catenin, connexin36, calretinin, and calbindin in the retina of guinea pig declined. CONCLUSION: There is frequency cumulative damage effect on the retina that relates to LARP illumination frequency. This has significance for staff visual protection policies under LARP lighting conditions.
