Assessment of focal laser photocoagulations' early effect on polypoidal choroidal vasculopathy with optical coherence tomography angiography.

Polypoidal choroidal vasculopathy (PCV) is seen with polypoidal lesions and branching vascular networks (BVNs) (Spaide et al. in Retina 15(2):100-110, 1995; Yannuzzi et al. in Retina 10(1):1-8, 1990). There are reports about laser photocoagulation for PCV (Yuzawa et al. in Japan J Ophthalmol 47(4):379-384, 2003; Lee et al. in Eye 23(1):145-148, 2009); however, all these reports are about final vision and frequent relapses. Therefore, this treatment merits rigorous scrutiny using optical coherence tomography angiography (OCTA).
