Summary
Idiopathic polypoidal choroidal vasculopathy (IPCV) is increasingly recognized. This report details the first Taiwanese case of IPCV, presenting a 63-year-old man with blurred vision and characteristic macular lesions.
Area of Science:
- Ophthalmology
- Medical Research
Background:
- Idiopathic polypoidal choroidal vasculopathy (IPCV) is a distinct clinical entity characterized by abnormal vascular networks and polypoidal lesions.
- Worldwide recognition of IPCV's prevalence and significance has grown since its introduction in 1990.
Observation:
- A 63-year-old Taiwanese male presented with a 6-month history of blurred vision in his right eye.
- Ophthalmoscopy revealed hard exudates and reddish-orange subretinal lesions in the macula.
- Anterior segment and vitreous examinations were unremarkable, aside from mild nuclear cataract.
Findings:
- Fluorescein angiography demonstrated hyperfluorescent granular lesions, subretinal leakage, and pooling in the macula.
- Indocyanine green angiography revealed multiple aneurysmal dilations within branching vascular networks.
- A hyperfluorescent aneurysmal lesion correlated with ophthalmoscopic findings, and granular lesions were noted on fluorescein angiography.
Implications:
- This case represents the first documented instance of IPCV in Taiwan, expanding the geographic understanding of the disorder.
- Focal retinal photocoagulation was applied to the leakage site, leading to partial resolution of subretinal fluid.
- Despite treatment, new macular leakage was observed, indicating the chronic and potentially recurrent nature of IPCV.
