Purpose:
To develop new micro vertical scissors for the ablation of retinal angiomatous proliferation (RAP) to minimize possible retinal damage.
Design:
Interventional case report.
Methods:
New micro vertical scissors were developed and used for the ablation of RAP vessels.
Results:
The length of the inner side of the tip is 180 microm, which is approximately one seventh that of regular vertical scissors. The scissors handled easily and the RAP vessels were ablated with less retinal damage compared with that associated with use of standard vertical scissors. Postoperatively, intraretinal hemorrhage was reduced and hyperfluorescence seen on indocyanine green angiography resolved.
Conclusions:
The new micro vertical scissors developed for the ablation of RAP vessels can be used safely and effectively during this surgical procedure.
