Clinical Evaluation of Individualized and Navigated Microsecond Pulsing Laser for Acute Central Serous Chorioretinopathy.

ABSTRACT

BACKGROUND AND OBJECTIVE: A computational model has predicted parameters for using a navigated microsecond pulsing laser system to treat central serous chorioretinopathy (CSC). PATIENTS AND METHODS: A prospective, single-center, interventional case series was conducted for patients with acute CSC who were enrolled following screening and informed consent. Treatment involved laser pulse duration of 50 µs, 2.4% Duty Cycle, 100 µm spot size, and 10 ms pulse duration. RESULTS: Average best-corrected visual acuity (decimal) of 12 patients improved from 0.86 ± 0.03 at baseline to 0.97 ± 0.01 at 3 months. Baseline central retinal thickness decreased from 452.58 µm ± 24.53 µm at baseline to 249.25 µm ± 2.92 µm at 3 months. Retinal sensitivity improved from 24.1 dB ± 1.09 dB at baseline to 28.98 dB ± 0.23 dB at 3 months. In all cases, subretinal fluid was resorbed. CONCLUSION: The parameter sets derived from the computer model can be applied safely and effectively for CSC treatment using the navigated microsecond pulsing laser system.
