[Value and limit of photocoagulation for juxtafoveolar sub-retinal vessels (author's transl)].
Sub-retinal new vessels arising from the choroid are the most dangerous components in disciform maculopathies. The greatest advance made in their treatment has been due to the use of photocoagulation over the last few years, but their destruction by this method is still a very controversial subject. The aim of the present study was to define which lesions should be treated and which should not. Results demonstrated that the use of photocoagulation to destroy new vascular membrane which is very close to the foveola, is possible, and can restore vision or preserve useful visual acuity. The laser can be used very close to the centre of the foveola, even in a part of the central avascular area. A randomized study is now being conducted and should supply statistical evidence as to whether this treatment should or should not be recommanded.
