To analyze vessel density of the whole choroid in Serpiginous Choroiditis (SC) using optical coherence tomography angiography (OCT-A).
Observational study. Nineteen eyes of 11 patients affected by Serpiginous Choroiditis were recruited. All patients underwent SD-OCT (Spectralis Heidelberg Retinal Angiograph + OCT; Heidelberg Engineering, Heidelberg, Germany) and OCT-A (AngioPlex Elite 9000 SS-OCT, Carl Zeiss Meditech, Inc., Dublin, USA). Quantification of vessel density of whole choroid was performed by means analysis of binarized 6x6 mm OCT-A images. Four different regions of the retina were chosen for investigation: unaffected area, inner border of the lesion, outer border of the lesion and affected retina. Border regions were defined as portion of retina within 30 µm from the dividing limit between affected and unaffected area.
Nineteen eyes of 11 Caucasian patients (3 males, 27.3%), with a mean age of 60.72 years ± 6.80 were enrolled. The whole choroid showed statistically significant reduction of vessel density in affected areas (0.235 ± 0.13) compared to unaffected areas (0.756 ± 0.14) (p <0.001), and between inner borders(0.330 ± 0.13) and outer borders (0.659 ± 0.13) of affected areas (p <0.001).Statistically significant differences in vessel density were detected between affected areas (0.235 ± 0.13) and inner borders (0.330 ± 0.13) (p=0.035) and between unaffected areas (0.756 ± 0.14) and outer borders of the lesion (0.659 ± 0.13) (p=0.038). Also the differences between affected areas (0.235 ± 0.13) and outer borders (0.659 ± 0.13), between unaffected areas (0.756 ± 0.14) and inner borders (0.330 ± 0.13) were statistically significant (p<0.001).
OCT-A demonstrated progressive loss of the whole choroid from the inner border of affected areas to unaffected areas in eyes with Serpiginous Choroiditis.
