[Subretinal neovascularization: evolution of cicatrix of photocoagulation in the absence of recurrence]

Eleven patients successfully treated with the argon or krypton laser for macular subretinal neovascularization were followed up in order to determine the extent of long-term enlargement of the chorioretinal scars. The mean follow-up time was 51.5 months and the mean increase in choroidal scar size 46.5%. In 10 patients the scars enlarged more toward the fovea than toward the periphery (51% as opposed to 43%). The rate of enlargement per month decreased with time after treatment. Only one patient exhibited decreased visual acuity during the follow-up period, due to invasion of the foveola by the scar.
