Astonishing Auto-Segmentation!

Putting aside the exquisite choroid OCTA picture (above), the perfect accuracy of auto-segmentation alone is also astonishing (below). And this, is just one of the hundreds of standard functions from TowardPi full range swept source OCT/OCTA.

Retinal Macroaneurysm revealed by 3D full range SS-OCTA!

Retinal Macroaneurysm revealed by 3D full range SS-OCTA! An 82-year-old female who had a history of arteriosclerosis complained vision loss in her right eye. The visual acuity was 20/50 in her right eye while 20/30 in her left eye. Intraocular pressure in both eyes was normal. Color fundus images discovered bilateral refractive media opacity and a spindle-shaped lesion nearby a small branch retinal artery inferotemporal to optic disc in her right eye (fig. 1 blue circle). High-resolution B-scan image revealed thickened retina with subretinal fluid (fig. 1 thickness map). An oval hyperreflective entirety was found located in the internal retina with relatively low internal reflection, corresponding to the spindle-shaped lesion on color fundus and SLO image (fig.1 blue arrow). 12mm x 12mm OCTA image clearly showed a retinal macroaneurysm with internal blood signals detected on the flow-overlaid B-scan image (fig. 2). It was more obvious with higher flow density on the vessel density map (fig. 2 white circle). With 3D reconstruction of the angiography, the morphology of the macroaneurysm and the spatial relationship with the retinal vessels could be vividly observed (gif. red arrow). A TowardPi full range SS-OCTA #YAlkaid was used in this case to acquire comprehensive structural and flow information of the retinal macroaneurysm. Thickness map and flow density can be quantified on the device. Structure and flow can both be reconstructed in three-dimension for further exploration of diseases.

Quantitative imaging Biomarkers of PCV by Using Full Range SS-OCTA!

Quantitative imaging biomarkers of PCV by using full range SS-OCTA! Research recently published in evaluated quantitative metrics of neovascularization lesions and choroidal vascular in PCV eyes, and investigated the relationship between imaging biomarkers and anti-VEGF treatment outcome by using full range SS-OCTA. The results indicated that a higher number of endpoints and lower average vessel length of PCV lesions were correlated with high shrinkage of vessel area after anti-VEGF treatment, and a lower subfoveal choroidal thickness was correlated with good morphological response to anti-VEGF. Therefore, ‘quantitative metrics of neovascularization lesions and choroidal characteristics using SS-OCTA had the potential to be imaging biomarkers for predicting the response to anti-VEGF treatment’. A 400kHz speed swept source OCTA (BMizar, TowardPi Medical) was used in this study to acquire high-resolution image of neovascularization and choroidal vessels with built-in precise segmentation algorithm and choroid angiography algorithm. Choroid quantitative parameters such as subfoveal choroidal thickness (SFCT) and choroidal vascularity index (CVI) are available on device. Further quantitative metrics based on high-resolution OCTA images, including total vessel length (TVL), average vessel length (AVL), junction density (JD), total number of endpoints (TNE), and mean lacunarity (ML), were evaluated in this research. This research is authored by Dr. Yue Zhang, etc. team of Prof. Xiaobing Yu, from Beijing Hospital. Link to original text: https://www.sciencedirect.com/science/article/abs/pii/S0026286224001080

TowardPi Announced Partnership with Nikon to Jointly Develop the Japanese Ophthalmology Market

As the high-end ophthalmic equipment brand TowardPi Medical continues to grow in the Chinese and international markets, it announced that it has officially entered into a strategic agreement with Nikon Solutions, a subsidiary of Japanese imaging equipment giant, Nikon. Nikon Solutions becomes the exclusive distributor of TowardPi Medical, including the promotion, sales and after-sales service of OCT products throughout Japan. The strong entry of TowardPi brand into Japan through well-known local channels is expected to significantly change the market pattern of Japanese ophthalmological devices in the near future. About Nikon Founded in 1917, as a world-renowned designer and manufacturer of optical products, Nikon Technology plays an important role in various fields of human production and life, such as imaging, optical fiber, semiconductor, optometry, scientific research, etc. Nikon and Japanese Ophthalmology In 2015, Nikon took full control of Optos in the United Kingdom, whose 200-degree range color fundus camera enjoys a high reputation and market share in the world. In 2018, Nikon once again integrated an 89-year-history company Chuo Sangio Co., which had more than 1,000 ophthalmic OCT installation and maintenance experience as a long-term distributor in Japan for Oculus of Germany and Optovue of the United States.   Japanese ophthalmologists gathered at the booth of Nikon Solutions to visit the powerful performance of TowardPi OCT in the 78th JCO congress. About Nikon Solutions Nikon Solutions was founded in 2007 and is wholly owned by Nikon. It is mainly engaged in the import and export and sales services of optical, measuring, medical, laboratory, calculator and other equipment. Headquartered in Tokyo, it has branches all over Japan. Nikon Solutions is responsible for the Japanese market for Optos in the UK and Oculus in Germany. TowardPi became the third major ophthalmic medical device brand to be introduced to Japan by Nikon Solutions. "As such a well-known company, it is natural to cherish its own image. Nikon has always held itself to a very high standard when it chooses to introduce brands to Japan.” Jian Zhou, vice president global of TowardPi Medical, said, "The cooperation agreement reached between Nikon and TowardPi Medical is also the result of repeated investigation and testing. It shows Nikon's high confidence in the performance and quality of TowardPi ophthalmic equipment.” “In addition to personally inspecting the company and facilities of TowardPi Medical, we also listened to the opinions of many ophthalmologists in Japan. For example, at the recently concluded the 78th Congress of Japan Clinical Ophthalmology, we presented two OCT products of TowardPi Medical, BMizar and Yalkaid. The effect of the exhibition was even more popular than expected, TowardPi's zone were surrounded by Japanese ophthalmologists.” Kentaro Furukawa, Marketing Manager of Ophthalmology at Nikon Solutions, said, "At the same time, we have also received feedback and demand from many Japanese doctors who have participated in international exhibitions and seen the products of TowardPi, which further confirms our judgment on the excellent performance of TowardPi products and the good expectations of the future market.”   The team of Nikon Solutions at the training and certification in TowardPi Shanghai Office Nikon Solutions has completed the training and certification of the application and service of TowardPi Medical, and started the process of registration for TowardPi products in Japan, in preparation for the official entry into the Japanese market. * This press release is not intended as an advertisement.

Two LHON Cases Revealed by Full Range SS-OCTA!

Two LHON cases revealed by full range SS-OCTA! A 12-year-old boy was found severe optic nerve atrophy in his both eyes because of vision lost together with visual field defect especially the nasal part field of vision. Structural and flow analysis showed symmetrically thin nerve fiber layer on the temporal side in both eyes together with reduced flow density of peripapillary capillaries and enlarged optic disc area. GMA report revealed severe ganglion cell lost in both eyes. The flow density of nerve fiber layer at macular was also diffusely declined (figure 1). This boy was diagnosed as Leber hereditary optic neuropathy (LHON) by gene detection. The pathogenic gene locus was 14484. Another 23-year-old male LHON patient was found similar to this boy and pathogenic gene locus was 11778. The color fundus images showed pale optic discs and even severe nerve fiber atrophy. Structural and flow analysis revealed almost total loss of nerve fiber layer (figure 2). A 400kHz speed swept source OCTA (#BMizar, TowardPi Medical) and a 100kHz speed SS-OCTA (#YAlkaid, TowardPi Medical) were used in these two cases. Both devices can provide comprehensive structural, including optic disc and nerve fiber layer analysis and ganglion cell analysis, and flow analysis to the disc and macula of neuropathy based on high-resolution B-scan and precise segmentation algorithm. A progression analysis can be easily generated for disease management. Case courtesy of: Dr. Meng Chen and Dr. Haiyan Sun, team of Prof. Jihong Luo from Hubei University of Chinese Medicine.
