Abstract
BACKGROUND AND OBJECTIVE: To evaluate punctate hyperfluorescent spots on indocyanine green angiography (ICGA) in eyes with polypoidal choroidal vasculopathy (PCV). PATIENTS AND METHODS: Retrospective observation case series of 88 eyes of 81 patients (63 men and 18 women) analyzing fundus photography, fluorescein angiography, ICGA, and spectral-domain optical coherence tomography (OCT) findings at baseline. RESULTS: Seven patients (9%) had bilateral PCV lesions. Mean age was 68.44 ± 5.94 years (range: 45 to 86 years). Macular-type PCV was found in 72 eyes (81.8%), peripapillary-type PCV in 12 eyes (13.6%), and combined-type PCV in four eyes (4.5%). Choroidal vascular hyperpermeability was observed in 38 eyes (43.2%), and punctate hyperfluorescent spots on ICGA in 47 eyes (53.4%). ICGA of unaffected fellow eyes of 74 patients with unilateral PCV revealed choroidal hyperpermeability in 23 eyes (31.1%) and punctate hyperfluorescent spots in 38 eyes (51.4%). Presence of punctate hyperfluorescent spots was significantly associated with choroidal vascular hyperpermeability (P < .001). CONCLUSION: Punctate hyperfluorescent spots were frequently observed in eyes with PCV in late-phase ICGA, as previously described in eyes with central serous chorioretinopathy, which may represent leakage from punctate hyperpermeable inner choroid spots or late staining of forme fruste drusen or drusen-like subretinal pigment epithelium deposits associated with choroidal hyperpermeability.
