Correlation of retinal curvature with choroidal remodeling in myopia revealed by UWF full range SS-OCT！
Research published in evaluated the relationship between retinal curvature (RC) and retinal and choroidal quantifications, including retinal vessel density (RVD), subfoveal choroidal thickness (SFCT), choroidal vessel index (CVI), choroidal stromal volume per unit area (CSV/a) and choroidal vascular volume per unit area (CVV/a), in myopic patients by using UWF full range SS-OCT.
332 participants were enrolled in this study. High myopia demonstrated significantly reduced average RC. A positive correlation with the SFCT was revealed. In the macular region, average RC was positively correlated with the RVD, CSV/a and CVV/a, but showed a weak negative correlation with the CVI. In the optic disc region, RC showed significant positive associations with CVI, CSV/a, and CVV/a, suggesting that choroidal vascular contraction and concurrent stromal atrophy may serve as important mechanisms for maintaining choroidal blood perfusion stability. All these results provided an insight into choroidal remodeling in myopia development as a key feature of active accommodation.
A 400kHz speed swept source OCTA ( , Medical) was used in this study to acquire 24mmx20mm UWF OCTA images for retinal curvature according to AL with built-in software. A curvature map detailing 3-dimension Gaussian curvature of each point is generated, providing a quantitative indicator of eyeball morphology for long-term clinical monitoring.

Transscleral imaging of choroidal detachment using AS SS-OCT！
A 56-year-old woman presented choroidal detachment and retinal detachment in her right eye. In order to evaluate the extent of the choroidal detachment and to overcome iris occlusion, a transscleral approach was used to acquire high-resolution anterior segment (AS) OCT images of extensive choroidal detachment in different orientations (red arrows) because of low pigment content and minimal light absorption in sclera. Nasal detachment extending into the ciliary body was clearly documented (fig.A).
A 400kHz UWF speed full range swept source OCTA ( , TowardPi Medical) was used in this case for high-resolution AS-OCT images, offering excellent pe*******on and superior evaluation of choroidal detachment compared with ultrasound biomicroscopy.
This case was published in , authored by Dr. Guoren Xu and Dr. Cong Chen, team of Prof. Yanping Song from General Hospital of Central Theater Command, Wuhan, China.

Cellular-level macular characteristic of FEVR revealed by multimodal imaging！
Research recently published in investigated the characteristics of macular development at a cellular level in patients with familial exudative vitreoretinopathy (FEVR) without foveal hypoplasia (FH) using multimodal imaging.
A 400kHz UWF speed full range swept source OCTA ( , TowardPi Medical) was used in this study to acquire 24mm x 20mm high-resolution OCTA images of FEVR patients. Detailed retinal thickness and vessel density were analyzed focused on macula with built-in AI segmentation algorithm, providing novel insights into macular development in patients with FEVR. Although all patients represented normally developed macular foveas, FEVR eyes with normal BCVA showed highly asymmetrical irregular FAZ zone with distorted edges, particularly in the deep capillary plexus (DCP). A tendency of thickening inner retina layers and thinning outer nuclear layer in parafovea area was also noticed, as well as lower vessel density of DCP. AO-SLO discovered irregular cone distribution, exhibiting lower foveal and higher parafoveal cone densities.

Crossing the “antipodes”, TowardPi travels 20,000 kilometers to the farthest end of the Earth✈️

“Antipodes” refers to two points on opposite ends of the Earth. 12 time zones apart, opposite day and night, reversed seasons, 20,000 km minor great-circle distance.

TowardPi’s Global Business Center is located in Shanghai, China (31°N, 121°E). Its antipodal city is Concordia, Argentina (31°S, 58°W), a lovely place with 180,000 residents.

Recently, two TowardPi OCT BMizar (400kHz speed) have been purchased and installed consecutively in beautiful Concordia at Clínica Razzari and Instituto Oftalmológico Dr. Álvarez.

“From Concordia, Argentina — nearly the farthest point on the map from China, we chose BMizar because its imaging depth, clarity, and analytical power clearly outperformed the alternatives, proving that clinical quality has no borders.” - Dr. Armando Horacio Razzari.

“When evaluating new diagnostic equipment, we selected TowardPi’s BMizar as the most advanced OCTA system available at the time; although it represented a significant investment and TowardPi is a relatively new brand from China Asia, we felt confident moving forward based on OMNI SRL’s expertise and long-standing reputation in the national OCT market.” – Dr. Héctor Eugenio Álvarez.

“The delivery of orders to Earth’s antipodal point signifies that TowardPi’s devices have reached the farthest accessible distance on our planet’s surface. It marks how our equipment is now spreading across the globe.” - Dr. Jian Zhou (VP Global, TowardPi Medical).

Since its international launch just over a year ago, TowardPi’s devices have rapidly expanded into more than 40 countries, establishing a presence across all five continents.

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.
