Photoreceptor Layer Regeneration is Detectable in the Human Retina Imaged by SD-OCT after Laser Treatment Using Subthreshold Laser Power
Purpose. We evaluated the morphologic changes in retinal structure after laser photocoagulation using supra- and subthreshold laser fluence. Methods. In a prospective cohort study 10 consecutive patients received scatter laser photocoagulation. Treatment was performed using a semiautomated patterned scanning laser system. In a study area adjacent to the temporal vessel arcades, 2 × 2 pattern laser spots were applied with halving the flux of the laser power in a stepwise manner starting from a power producing a typical grayish lesion. The study areas then were imaged on days one, three, and seven, and on months one, two, three, and six using ...
