Purpose To analyze and describe serial follow-up of choriocapillaris alterations in tubercular serpiginouslike choroiditis (SLC) using optical coherence tomography angiography (OCTA) and to compare it with multimodal imaging. Methods In this prospective cohort study, patients with active tubercular SLC underwent OCTA using Optovue RTVue XR Avanti and other imaging techniques including enhanced-depth imaging OCT (EDI-OCT) (Heidelberg Spectralis; Heidelberg Engineering, Heidelberg, Germany), fundus autofluorescence, fluorescein angiography, and indocyanine green angiography. Serial imaging was performed for a total follow-up of 3 months. Choriocapillaris alterations at the site of lesions were analyzed on OCTA imaging, and their mean lesion areas were calculated. Results Twenty-six eyes (26 patients; 20 males; mean age: 32.68 ± 10.56 years) were included. Fourteen eyes had active multifocal lesions (n = 39), whereas 12 eyes had active placoid lesions (n = 12). At baseline, OCTA showed hyporeflective flow deficit lesions corresponding to the hypofluorescent lesions on indocyanine green angiography in all eyes. In the multifocal type of SLC, the mean lesion area decreased in all eyes compared with baseline, and lesions with a lesion area less than 0.1 mm2 on OCTA showed near-complete resolution with minimal choriocapillaris atrophy. In comparison, all eyes with a placoid type of SLC showed no significant reduction in the lesion area and showed extensive choriocapillaris atrophy. Conclusion Optical coherence tomography angiography has the unique ability to demonstrate pathological flow impairment at the level of choriocapillaris in active tubercular SLC. Serial OCTA analysis reveals that large tubercular SLC lesions result in choriocapillaris atrophy as the lesions heal, whereas smaller multifocal lesions show resolution of choriocapillaris hypoperfusion with minimal atrophy.
