Fig1. 120°single captured OCT Angiography (SVC slab). Hemangioblastoma near the disc with significant blood flow (red circle). Another angioma got detected on the peripheral temporal side (red arrow).

Fig2. Radial lines scan centered on disc-side hemangioblastoma. In addition, PVD, ERM, RD, and cystoid retinal edema were visualized.

Fig3. 120° enface of SVC slab (same scan of Fig1). Dark ring and folds around angioma indicated epiretinal membranes.

Fig4. 24mm Line scan, walked through peridiscal (right side in picture) and peripheral (green arrow) hemangioblastoma.

Fig5. 3x3mm OCTA (retina slab) on the peripheral hemangioblastoma, before and instantly after thermal laser photocoagulation. Angioma and feeder vessel closed after treatment.

“The wide-field OCTA of TowardPi breaks through the limitation of ‘small acquisition range’ from the previous systems. It obtains a wider range of OCT, OCTA, Enface and more information in one acquisition, making a huge step towards ‘no omission of lesions’. 400KHz speed, 120° range and consistent high resolution make it possible to apply a wide range OCTA to the clinic. It may change the current examination process.” – Dr. Huan Chen
