What are subfoveal leakages from neovascularizations?
When angiography is performed, if the points of leakage are either in or at the edge of the fovea, then the leakage is said to be subfoveal. Laser photocoagulation should not be performed on subfoveal leakage points because the laser destroys the portion of the fovea which is exposed to the laser beam. That does more severe damage to the patient’s vision than can be justified by the possible temporary stopping or slowing of macular degeneration.
