Anterior Segment OCTA of Melanocytic Lesions of the Conjunctiva and Iris
Purpose To study the feasibility and diagnostic value of vascular imaging using OCT-Angiography (OCTA) of melanocytic lesions of the conjunctiva and iris. Design; Cross-sectional study. Methods Twenty-five patients with an untreated conjunctival lesion (5 melanoma, 13 nevus, 7 primary acquired melanosis (PAM) and 52 patients with an untreated iris lesion (10 melanoma, 42 nevus) were included. Patients were imaged using a commercially-available OCTA device, with addition of an anterior segment lens and manual focussing. Tumor vessel presence, vascular patterns and vascular density were assessed. Results Good OCTA images were obtained in 18/25 conjunctival lesions, and 42/52 iris lesions ...
