N2 - Purpose: To report 3 cases of ocular chorioretinal folds from different etiologies and their aspect with the new imaging technology of optical coherence tomography (OCT) angiography (OCT-A). Methods: Baseline data, investigational process on etiology, and follow-up data of patients referred for chorioretinal folds to the Medical Retina & Imaging Unit of San Raffaele Hospital in the period January-March 2016 were collected. Multimodal imaging evaluation, comprehensive of infrared, fundus autofluorescence, multicolor, spectral-domain OCT, and OCT-A, was performed on all patients. Results: Four eyes of 3 men, 65, 46, and 50 years of age, showed chorioretinal folds secondary to central serous chorioretinopathy, postoperative hypotony (after deep sclerectomy), and anisometropia with unilateral hyperopia, respectively. In all cases, OCT-A imaging showed a signal reduction in the choriocapillaris layer in correspondence of the folds. Due to this signal reduction, the en face reconstruction of choriocapillaris layer showed, in all cases, a peculiar tigroid aspect. The aspect of the folds at OCT-A remained unchanged during the 3-month follow-up in all patients. Conclusions: Optical coherence tomography angiography shows a typical linear signal reduction in the choriocapillaris layer in correspondence of the fold with a tigroid pattern. We hypothesize this aspect could be explained by blood flow alteration at the choriocapillaris level in correspondence of the fold. © 2017 Wichtig Publishing.
