exposure wavelength
1.Because the threshold exposure levels for photic damage to the retina at each wavelength of the optical spectrum are well known, it is fairly simple to calculate the maximum permissible filter transmittance that will provide adequate retinal protection from sunlight.
2.Methods Thirty- one cases of CSC, which were diagnosed by fundus fluorescein angiography, were treated by krypton yellow laser(wavelength 568nm) with the following parameters: spot size 100μm, exposure time 0.1s, power 60 - 120mw and 3 - 12spots.
