Modified Low Power Mode Laser for the Treatment of Central Serous Chorioretinopathy

Purpose: Low power mode (LPM) can be used for subthreshold retinal laser treatment by simply adjusting the laser parameters. Herein, we report the use of a modified LPM laser treatment for four cases of central serous chorioretinopathy (CSCR). Patients and Methods: We retrospectively reviewed the medical records of four patients (four eyes) with persistent CSCR who underwent modified LPM laser for leakage. The laser power was first titrated with a barely visible burn, and then treatment was applied using 33% laser energy by manually adjusting the laser power and duration. Results: Serous retinal detachment completely resolved in all cases by 2 months after treatment. Autofluorescence images did not show any specific changes induced by laser burns. Conclusion: A modified LPM laser may provide a feasible treatment for persistent CSCR.
