Two weeks following laser photocoagulation, the patient should be observed and undergo fluorescein angiography. Pay special attention to the borders, especially the foveal border, of the laser treatment zone to detect any persistence. If no leakage is detected, the patient should have another fluorescein angiogram 4 weeks later or if there are new changes on the Amsler grid. If no leakage is detected again, another angiogram should possibly be obtained 4-6 weeks later.

Clinical examination cannot replace FA during the first 18 months after laser treatment, because most persistent and recurrent leakage occurs during this period.
