Clinical characteristics of 254 cases of polypoidal choroidal vasculopathy

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.
