Retinal vascular features of Beta-Thalassemia captured by UWF full range SS-OCTA！
A 14-year-old girl presented with bilateral vision loss for 3 months was diagnosed as Beta-thalassemia by genetic testing. Ultra-widefield SS-OCTA images revealed extensive nonperfusion areas involving macular area in her both eyes. High-resolution ultra-widefield OCT B-scan images showed clearly hyperreflective inner retina in macula with absence of flow signals, demonstrating the ischemia retinal tissue corresponding to the nonperfusion areas. This patient underwent hematopoietic stem cell transplantation and long-term monitor of retinal perfusion.
This case was published in , authored by Dr. Xinyu Zhao, etc. team of Prof. Guoming Zhang from Shenzhen Eye Hospital.
A 400kHz speed swept source OCTA ( , TowardPi Medical) was used in this case to reveal details of retinal vasculatures with exquisite resolution in an ultra-wide field, providing a convenient and effective method for early diagnosis, decision making and long-term disease management.

PVD may systematically influence neovascularization of PDR studied by UWF full range SS-OCTA！
Research recently published in investigated the association between posterior vitreous detachment (PVD) and the progression of proliferative diabetic retinopathy (PDR) by analyzing the morphological evolution of neovascularization (NV) across PVD stages using a UWF full range SS-OCTA.
PVD stages and NV morphology were assessed and quantitatively analyzed. The results revealed that NV in early stage of PVD exhibited a significantly highly intricate and extensive structure and greater viability. In contrast, NV in stage 4 PVD (complete PVD) tended to be a simplified and localized architecture, indicating that PVD status might systematically influence the NV activity and complexity. This study provided morphological insights into the role of PVD in PDR patients.
A 400kHz speed swept source OCTA ( , TowardPi Medical) was used in this study for high-resolution visualization of the status of PVD and quantitative parameters of NV including vessel area, vessel density and so on with the assistance of built-in AI technology on device.
This study is authored by Dr. Zikang Xu, etc. team of Prof. Liang Zhang and Prof. Xuenan Zhuang from Guangdong Provincial People's Hospital.

Relationship between age, AL and choroidal vasculature characteristics revealed by UWF full range SS-OCTA!
Research published on evaluated the features of choroidal Sattler’s and Haller’s layer (CSHL) vessels in adults and explore its relationship with age, axial length (AL) and body mass index (BMI) in normal adults by using UUWF full range SS-OCTA.
The results indicated that choroidal vessel index (CVI) could be a more stable parameter for describing choroidal medium and large-sized vessels compared to choroidal vessel volume (CVV). Higher CVI was associated with younger age and shorter AL. Meanwhile, longer AL was associated with attenuated CVV. Neither CVI nor CVV has association with BMI.
A 400kHz speed swept source OCTA ( , TowardPi Medical) was used in this study to visualized and quantify vasculature of choroidal Sattler’s and Haller’s layer in ultra-widefield with built-in AI segmentation algorithm. 3D-CVI and CVV can be quantified easily on device.

“Vascular diseases diagnosis in one scan” Dr. Ali Erginay from Hôpital Lariboisière, Paris, France, talks about TowardPi.

“From cornea to choroid, involves the whole eye.
It can replace FFA and, in some cases, even ICG.
With a single scan, you can make a diagnosis, assess the severity of the pathology, and choose the appropriate treatment.
It’s a complete machine—you can do everything with it.”

Genotype-specific choroidal characteristics in RP revealed by UWF SS-OCTA！
Research published in quantified retinal and choroidal vascular changes in Retinitis pigmentosa (RP) patients with five genotypes by using UWF full range SS-OCTA and investigated the correlation between perfusion patterns and genotypes.
Defects were observed in each layer among all RP groups, showing different patterns of damage to the vasculature, correlating with retinal function. Significant hypoperfusion in the peripheral retina was observed in EYS, RPRH2, RPGR, and USH2A groups, while a relatively large decrease was observed in the central part was seen in CYP4V2 group. A linear correlation was also observed between the choroidal vessel index (CVI) and retinal function parameters, especially in the RPGR group. All these results suggested that vascular dysfunction in RP might serve as a diagnostic, prognostic and therapeutic biomarker in disease management.
A 400kHz speed swept source OCTA ( , TowardPi Medical) was used in this study to visualized and quantify retinal and choroidal vascular defects in ultra-widefield. Comprehensive perfusion density parameters of each layer in retina and choroid can be easily achieved on device for all sizes, providing a promising tool for early detection and disease management with high repeatability.
This research is authored by Dr. Yu Rong, etc. team of Prof. Qing Chang and Prof. Jihong Wu from Eye and ENT Hospital, Fudan University.
