Angiographic features of polypoidal choroidal vasculopathy using indocyanine green angiography and optical coherence tomography angiography: A comparative study.
Eur J Ophthalmol. 2020 Sep; 30(5):1076-1081.EJ

Abstract

BACKGROUND

To compare the vascular lesion size using optical coherence tomography angiography and indocyanine green angiography in eyes with polypoidal choroidal vasculopathy.

METHODS

Treatment-naïve cases (46 eyes of 44 patients) with polypoidal choroidal vasculopathy were retrospectively analyzed. The comparison of mean area of branching vascular network and polyp detection rate was done between indocyanine green angiography and optical coherence tomography angiography and correlated with various optical coherence tomography features.

RESULTS

The mean age of the study patients was 62.33 ± 10.74 years. The mean branching vascular network size was 7.47 ± 5.74 and 7.51 ± 5.69 mm² in indocyanine green angiography and optical coherence tomography angiography, respectively, with an excellent correlation (r = 0.997). Optical coherence tomography angiography overestimated (mean ± SD: 0.28 ± 0.19 mm²) and underestimated branching vascular network area (0.36 ± 0.33 mm²) in 23 eyes each as compared to indocyanine green angiography. However, the difference in branching vascular network size was not statistically significant (p = 0.53). Indocyanine green angiography and optical coherence tomography angiography could identify polyps in 43 of 46 (93.48%) and 32 of 46 (69.57%) patients, respectively.

CONCLUSION

Branching vascular network size measurements with indocyanine green angiography and optical coherence tomography angiography were comparable and showed significant correlation, albeit the polyp identification rate was lower with optical coherence tomography angiography. Optical coherence tomography angiography may serve as a useful substitute to indocyanine green angiography in measurements of branching vascular network for photodynamic therapy and follow-up of polypoidal choroidal vasculopathy eyes.
