120°OCTA image of NPDR eye (Fig1), non-perfusion, microaneurysms and IRMA.

(Fig2) Flow density in customized grids, extremely low value in the area of nasal and inferior. Relatively normal value in macular.

Auto detected FAZ indexes (Fig3) shows non-ideal circularity, (from 0 to 1, 1 means perfect circle round).

(Fig4) is the structure enface of SVC (superficial vascular complex) slab. Wrinkles and folds in macula are from epiretinal membranes, that explains the circularity value from Fig3. Laser spots from PRP can be observed in peripheral, which are invisible from the flow image (Fig1)

Retinal thickness map (Fig5) presents intensive macular edema. Two values from each customized grids represent thickness (in micron) and volume (in cubic millimeter).

Data collected through one single capture in 15 seconds, by BMizar (BM-400K), a 400KHz speed Swept Source OCT from TowardPi. With comprehensive quantification analysis tools.

“TowardPi full range OCT Angiography not only makes up for the shortcomings of traditional method, solves the actual clinical needs, but also provides a huge boost to our academic research!”Endorsement and image courtesy of Prof. XiaoLing Liang, from Zhongshan Ophthalmic Center, Sun Yat-Sen University, Guangzhou, China
