Correlation of "Panoramic" Optical Coherence Tomography Angiography With Indocyanine Green Angiography Characteristics of Serpiginous-Like Choroiditis.

BACKGROUND AND OBJECTIVES

To analyze the panorama optical coherence tomography angiography (P-OCTA) characteristics of serpiginous-like choroiditis (SLC) and to correlate these findings with indocyanine green angiography (ICGA).

PATIENTS AND METHODS

Prospective, observational study of 32 eyes of 24 patients. Twenty-seven eyes of 16 patients who met inclusion criteria were included in the final study. Multimodal imaging was performed using P-OCTA, OCT, fundus autofluorescence, fluorescein angiography, and ICGA. Morphologic features at the site of lesions were analyzed using P-OCTA and correlated with ICGA.

RESULTS

P-OCTA in active phase revealed areas of large flow void, which correlated with hypofluorescent areas on ICGA. Healing phase revealed appearance of vascular network due unmasking of choriocapillaris that corresponded to reduced hypofluorescence on ICGA.

CONCLUSION

P-OCTA as a noninvasive tool provides widefield and high-resolution images that can be used as an complementary tool to ICGA for diagnosis of SLC cases. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:859-869.].
