OPTICAL COHERENCE TOMOGRAPHY 2

Abstract

To investigate the utility of new wide-field optical coherence tomography (OCT) device in the evaluation of mid and far retinal periphery and to show its feasibility and advantages in clinical practice. Consecutive patients underwent a complete ophthalmologic examination including standard OCT and new prototype OCT2 derived from Heidelberg Spectralis. Thirty-one eyes of 31 patients were studied with a total of 44 lesions, including 18 retinal detachments, 15 retinal holes and tears, 9 retinoschisis, and 2 retinal tufts. Fourteen (32%) lesions were found in mid and 30 (68%) in far periphery with 9 (20%) lesions in the superior region, 10 (23%) in the superior temporal, 8 (18%) in the temporal, 4 (9%) in the inferior temporal, 7 (16%) in the inferior, 4 (9%) in the nasal, and 2 (5%) in the superior nasal. Among the lesions evaluated by OCT2, 10 (71%) in mid periphery and 11 (37%) in far periphery could be imaged by standard OCT. The introduction of OCT2 into clinical practice may provide significant benefits for imaging peripheral retinal disorders. The application of OCT2 technology with 55° lens and scan length and angle modulation could improve our understanding of peripheral vitreoretinal disorders and facilitate their management.
