Abstract: Objective To observe the clinical characteristics of polypoidal choroidal vasculopathy (PCV).Methods Two hundreds fifty-four PCV patients (306 eyes) were enrolled in this study.All the patients were examined for corrected visual acuity (BCVA) testing,slit-lamp microscope,indirect ophthalmoscopy,fundus photography,fluorescein angiography,indocyanine green angiography and optic coherence tomography.Results The patients included 152 males (59.8%) and 102 females (40.2%) ; the age was from 38 to 91 years,with a mean age of (65.4±8.9) years.Bilateral lesions were observed in 52 patients (20.5%) and unilateral lesions were observed in 202 patients (79.5%).BCVA varied from nonlight perception to 1.2.BCVA was lower than <0.1 in 167 eyes (54.6%),≥0.1 but <0.3 in 92 eyes(30.1%) and ≥0.3 in 47 eyes (15.4%).Vitreous hemorrhage was observed in 61 eyes (19.9%).In 202 patients with unilateral PCV lesions,drusen can be observed in the contralateral eyes of 68 patients (33.7%),exudative age-related macular degeneration changes in the contralateral eyes of 24 patients (11.9 %),and central serous chorioretinopathy history was positive in the contralateral eyes in nine patients (4.5%).In 306 eyes,there were 43 eyes (14.1%) with high permeable choroid.PCV lesions located at macula area in 199 eyes (65.0%),under the temporal retinal vascular arcade in 49 eyes (16.0%),and peripapillary in 15 eyes (4.9%).PCV lesion formation was single in 110 eyes (35.9%),cluster in 176 eyes (57.5%),string in three eyes (1.0%),branch in four eyes (1.3%),and both single and cluster polyps in 13 eyes (4.2%).There were 125 eyes (40.8%) with sub-neuroretinal fluid,121 eyes (39.5%) with hemorrhagic pigment epithelium detachment,and 73 eyes (22.9%) with serous pigment epithelium detachment.Conclusion PCV patients have higher bilateral incidence and female prevalence,and lower rate of peripapillary lesions.
