Figure 3: Possible mechanism of subretinal or sub-RPE hemorrhage in asymptomatic PCV following cataract surgery. (a) When IOP increases during cataract surgery, choroidal blood flow decreases. (b) When IOP decreases, choroidal blood flow increases. (c) Fragile site of polypoidal lesion can rupture when fluctuation of choroidal blood flow exists, and this can cause bleeding. (RPE: retinal pigment epithelium, PCV: polypoidal choroidal vasculopathy, IOP: intraocular pressure)
