Polypoidal choroidal vasculopathy in Taiwanese patients
1Department of Ophthalmology, Kaohsiung Municipal Hsia-Kang Hospital, Kaohsiung, Taiwan.
Summary
Polypoidal choroidal vasculopathy (PCV) is common in patients with neovascular age-related macular degeneration (AMD). Photodynamic therapy (PDT) with verteporfin effectively improves vision in both PCV and neovascular AMD patients.
Area of Science:
- Ophthalmology
- Medical Imaging
- Retinal Diseases
Background:
- Neovascular age-related macular degeneration (AMD) is a leading cause of vision loss.
- Polypoidal choroidal vasculopathy (PCV) is an important subtype of neovascular AMD.
- Indocyanine green angiography (ICGA) is crucial for diagnosing PCV.
Purpose of the Study:
- To determine the incidence of PCV in patients with presumed neovascular AMD using ICGA.
- To evaluate the efficacy of photodynamic therapy (PDT) with verteporfin for PCV and neovascular AMD.
Main Methods:
- Retrospective review of 100 patients diagnosed with neovascular AMD via ICGA.
- Analysis of patient demographics, clinical presentation, and treatment outcomes.
- Follow-up assessments every 2 months for patients undergoing PDT.
Main Results:
- PCV was diagnosed in 49% of patients; neovascular AMD in 51%.
- PCV patients were younger (mean 63.6 years) and more likely to have unilateral involvement.
- Visual improvement was observed in 50% of PCV eyes and 50% of neovascular AMD eyes after PDT.
Conclusions:
- PCV is a frequent finding in Taiwanese patients with neovascular AMD, characterized by younger onset, male predominance, unilateral disease, and macular polyps.
- PDT with verteporfin offers favorable visual outcomes for both PCV and neovascular AMD.
- ICGA is essential for differentiating PCV within the neovascular AMD spectrum.
