Evaluation of chorioretinal complex tissue response on subthreshold micropulse yellow laser (577-nm) photocoagulation of retina in experiment

Akopyan et al evaluate chorioretinal complex (CRC) tissue response on subthreshold micropulse yellow laser (577-nm) photocoagulation (SMYLP) of rabbit retina in experiment and to determine its safest laser exposure energy settings. Morphological study was performed to determine the safest laser exposure settings, which do not cause CRC structure damage. The study was carried out in 8 eyes of 8 rabbits 24 hours and 1 month after the SMYLP. Results showed no retinal structure changes after SMYLP using low-level energy settings, including 100ms train duration and 5% duty cycle. SMYLP is safe for retinal structure integrity while using low laser exposure settings.
