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.

Related Experiment Videos

  • 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.
