Abstract

Purpose: Characteristics of Polypoidal Choroidal Vasculopathy (PCV) evaluated by Optical coherence tomography angiography. Materials and methods: analysis all the patients diagnosed PCV in ophthalmology department of National Geriatric Hospital from 8/2020 – 8/2021. Results: Twenty eight eyes of 28 patients ( 17 male, 11 female) were verified in ICG. Average age was 61,07 ± 8,41 years (max 80 years, min 44 years). ICGA detected PL in all eyes (100%), whereas OCTA detected PL in 17 eyes (60,7%); ICGA detected BVN in 14 eyes (50%), whereas OCTA detected BVN in 16 eyes (57,1%). All of the BVNs detected by OCTA were located between the RPE and Bruch’s membrane. The mean PA in ICGA and OCTA (OCTA+ and ICGA+) was 0,47±0.31mm2 and 0.17±0.16mm2. Conclusion: ICG is the gold standard in the diagnosis of PCV, using OCTA without dye injection may be useful to monitor progression or recurrence. OCTA might detect more BVNs and fewer PLs compared with ICGA, and PL detected by OCTA might be smaller than those detected by ICGA.
