A dangerous intraocular flower captured by UWF full range SS-OCTA！
A 40-year-old female patient was diagnosed as PDR with type 1 diabetes since childhood. Although this patient had undergone multiple applications of anti-VEGF and panretinal photocoagulation in both eyes, a neovascularization arising from the inferior temporal arcade of the right eye was clearly imaged by 400kHz UWF full range SS-OCTA ( , TowardPi ). High-resolution B-scan image from UWF 24mmx20mm OCTA revealed how the neovascularization broke through ILM, growing into the vitreous.
This wonderful case published in recently, authored by Prof. Martín Charles, Dr. Juan F. Méndez Arias and Dr. Tomás Erburu from Centro Oftalmológico Charles, Buenos Aires, Argentina.

Is it a good time to upgrade our OCT now? Let’s see what Dr. Maté Streho suggests.
“TowardPi OCT is a device that allows us to explore the entire pathology of both the anterior and posterior segments. It brings a whole new level of visualization of more structures in daily clinical practice.”
Thank you to Dr. Maté Streho and Centre Explore Vision. Together, we continue to maintain a leading position in eye care practice and management.

Insights into choroidal vascular changes in pachychoroid spectrum diseases using UWF SS-OCTA!
Research recently published in analyzed choroidal blood flow and anatomical changes in eyes affected by pachychoroid spectrum diseases (PSD) by using ultra-widefield (UWF) full range SS-OCTA.
The results indicated that the vortex vein drainage system played a key role in the pathogenesis of PSD. Central serous chorioretinopathy (CSC) groups exhibited significantly higher choroidal vessel volume per unit area (mCVV/a), choroidal vascularity index (CVI), and choroidal thickness (CT) compared to the pachychoroid neovasculopathy (PNV) and uncomplicated pachychoroid (UCP) groups. While the PNV and UCP groups shared similar choroidal vascular characteristics, the PNV group exhibited slightly higher choroidal vessel volume and notably the lowest foveal choriocapillaris density. Further analysis indicated that CNV in PNV could be attributed to choriocapillaris occlusion and ischemia resulting from mechanical compression by hypertrophic choroidal vessels. These findings suggested that choroidal structural and hemodynamic changes could serve as biomarkers for clinical diagnosis and treatment.
A 400kHz speed swept source OCTA ( , TowardPi Medical) was used in this study for high-resolution UWF OCTA imaging of choriocapillaris and the large and medium choroidal vessel layer with inbuilt algorithm. Numerous choroidal quantifications can be analyzed on the device, providing solid foundation for further longitudinal studies and enhancing our understanding of choroidal pathology mechanisms.

Precise ICL surgery under SS-iOCT！
With 100KHz full range SS-OCT integrated, intraoperative OCT guided ICL surgeries and intraoperative measurement are available by using digital navigation surgical microscope ( , TowardPi ).
During the surgery, it was possible to visualize the position of ICL in real time with high-resolution SS-OCT imaging (gif.1 right eye; gif.2 left eye). Precise intraoperative measurement of ICL vault was easy and immediate to ensure the visual outcomes of surgery (fig.).

AS-OCT imaging of lacrimal gland in patients with coGVHD！
A research recently published in 《Cornea》explored the image characteristics of the palpebral lobe of the lacrimal gland in patients with chronic ocular graft-versus-host disease (coGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) by using full range swept source AS-OCT.
This study revealed mille crêpe–like structures only in coGVHD patients which was found positively correlated with coGVHD severity and time after allo-HSCT. More blood vessels and slightly less visible lobules and ducts were verified in coGVHD group as well compared with normal control. And the number of blood vessels was positively correlated with time after allo-HSCT. This study provided a potential in the disease monitoring of coGVHD with full range AS-OCT.
A 400kHz speed swept source OCTA ( , TowardPi Medical) was used in this study to achieve high-resolution AS-OCT images of the lacrimal gland easily, providing solid method for quantifying the number of vessels and lobules and grading the mille crêpe–like structures of the glands.
This research is authored by Prof. Lingyi Liang from Zhongshan Ophthalmic Center, Sun Yat-sen University.

The fountain in the eye revealed by full range SS-OCT!
A 6-year-old kid was diagnosed as optic disc pit (ODP) in his left eye. The high-resolution SS-OCT images clearly revealed the pit with liquor leakage which looked like a fountain in the eye after 3D structural reconstruction. A 100KHz speed full range SS-OCT ( , TowardPi ) was used in this case for beautiful OCT images and precise diagnosis, providing a convenient imaging tool for pediatric patients.

📌“It really delineates recent change OCT technology. We are almost there in substituting FFA with this type of UWF-OCTA.” - Prof. Paolo Lanzetta, University of Udine & IEMO, Italy
📌“I’m fascinated by the delineation of the vessel without artifact, so we can have different types of quantification. This wide-field imaging is also replacement (FFA) for diabetic retinopathy or ischemic condition.” - Prof. Eric Souied, Hospitalier Intercommunal de Créteil, France
📌“This multi modality images not only OCTA but wonderful B-scan. Bigger, deeper, further, larger. Our journey into the eye has just begun.” - Dr. Ali ERGINAY, Lariboisière Hospital, France
📌“The miracle is coming. I can manage if patient is following prescribed therapy. It’s very easy to image children and elderly people, mostly children are forgotten by the standard OCT devices.”- Prof. Peter Maloca, University Hospital Basel, Switzerland.
📌“These evaluations are great encouragement to our R&D teams. There will be more powerful ophthalmic devices coming soon with top-end technologies and inventions.” - Dr. Jian Zhou, TowardPi Medical.
👏 Sincerely thank all thought leaders for their wonderful speeches at European Society of Retina Specialists (EURETINA) Symposium , and their high evaluation of TowardPi OCT systems.

Cornel Intralamellar Microstriae Repair Surgery under the guidance of iOCT！
A potential postoperative complication of SMILE (Femtosecond Laser Small Incision Lenticule Extraction) is the development of corneal intralamellar microstriae, which is the micro-folds within the corneal stroma. In the past, surgeons had to rely on experience alone to assess whether the corneal layers were smoothly repositioned. Now, with the assistance of high-resolution intraoperative OCT images under 100KHz digital navigation surgical microscope ( , TowardPi ), successful and high-efficient repair surgery can be accomplished with great confidence.
A 21-year-old male after SMILE was diagnosed as intralamellar microstriae in his left eye (fig.). During the repair surgery, the micro-folds in stroma could be clearly observed (gif.1 see in comment). The folds were precisely repositioned under the guidance of iOCT (gif.2 see in comment). The success of the repair and the surgical outcome could be reconfirmed immediately before the end of the procedure (gif.3 see in comment).
