Purpose: To report a vermilion polyp which developed prior to huge hematoma in polypoidal choroidal vasculopathy (PCV). Methods: We reviewed the records of 146 eyes of 141 patients (106 male and 35 female) with PCV which had hematoma from January 1997 to December 2001 at Gunma University Hospital. Patient’s age ranged from 51 to 71 (mean, 62 years). The follow–up periods were from 1 to 60 months (mean, 29.8 months). All patients underwent complete ophthalmologic examination, optical coherence tomography , fluorescein (FA) and indocyanine green (IA) angiography. Results: Vermilion polyp was seen in 15 of 146 eyes (10.2%). It was clearly differentiated from conventional orange lesion of polyp or hemorrhagic pigment epithelial detachment. Huge hematoma with 5 disc diameter or more was seen in 55 of 146 eyes (37.7%). Vermilion polyp was involved in huge hematoma in 11 of the 15 eyes (73.3%). In the remaining 4 eyes, vermilion polyp enlarged its size. In FA, vermilion polyp showed slight granular hyperfluorescence among the blocked fluorescent of hemorrhage. IA demonstrated multiple polyps with extensive dye leakage within retinal pigment epithelial detachment until late phase. Conclusions: Vermilion polyp appeared to be an impending sign of sequential huge hematoma. Vermilion polyp seems to be a collection of multiple polyps. Vermilion color may attribute to intra–polyp blood and attenuated retinal pigment epithelium. Early treatment for vermilion polyp may prevent a formation of huge hematoma and hemorrhagic insult to retina.
