Transient delay in choroidal filling after krypton red laser photocoagulation for choroidal neovascular membranes.
The authors report four patients who were treated with krypton red laser photocoagulation for neovascular membrane in the papillomacular bundle. In each patient, from 1 to 7 days following photocoagulation, there was a transient delay in filling of the choroid in a localized area beyond the treatment site. No patient suffered permanent visual loss as a result of this complication. Each patient regained normal choroidal filling (except for the treatment site) within two to four weeks. This angiographic observation may be explained by the increased uptake of the krypton red wavelength in the deep choroid.
