Abstract
Purpose :
To evaluate the diagnosis and treatment of polypoidal choroidal vasculopathy (PCV) and age-related macular degeneration (AMD) in Chinese and Caucasian Canadian patients.
Methods :
Retrospective chart review (431 charts). 37 eyes from 37 Chinese patients and 394 eyes from 394 Caucasian patients who were newly diagnosed with either AMD or PCV and had more than 1 year of follow-up were included. All newly diagnosed AMD patients presenting to the Retina Service of 4 retina specialists, between April, 2008, and September 30, 2017, were reviewed.
Results :
PCV was diagnosed in 17.6% of Chinese Canadians (6/37 eyes) and 12.8% of Caucasian Canadians (49/394 eyes). Indocyanine green angiography (ICGA) was used to diagnose PCV in 5.4% of Chinese Canadians and 0.5% of Caucasian Canadians. This is close to the expected prevalence published in the literature for these two groups.
Conclusions :
Despite the underutilization of ICG, PCV was still being diagnosed in our population. A careful qualitative analysis of the tomographic findings may help clinicians to distinguish between PCV and occult CNV, decreasing the need for ICGA.
