Real-time detection of anterior segment membranes during cataract surgery with SS-iOCT!
Research recently published in evaluated the intraoperative visualization of delicate membranous structures during cataract surgery using swept-source intraoperative optical coherence tomography (SS-iOCT).
6 complicated cataract surgeries were retrospectively studied. With fine pe*******on through opaque media like corneal edema and scar, the high-resolution real-time SS-iOCT enabled precise visualization of delicate membranous structures in all cases that were undetectable under traditional optical microscopes, including detached Descemet’s membrane and transparent anterior hyaloid membrane. The ability of SS-iOCT to delineate exact plane of separation and hidden lesions, such as the presence of synechiae and posterior capsule ruptures, directly guided intraoperative decision-making, leading to optimized surgical management and enhanced procedural safety.
An innovative digital navigation microscope ( , Medical), integrated with 100kHz intraoperative full range SS-OCT was used in this study, offering full-field real-time visualization in both complex and routine cataract surgeries. The significant advancement over conventional microscope systems illustrated the potential of full range SS-iOCT in optimizing surgical strategy for efficiency and safety.

A 14-year-old girl presented with bilateral vision loss for 3 months. Ultra-widefield swept-source OCT angiography (BM-400K BMizar, TowardPi Medical Technology; 160°) revealed extensive areas of nonperfusion, particularly involving the macular area (A, D). Widefield B-scans (24 mm) of both eyes demonstrated no significant macular structural abnormalities (B, E). However, flow within the retinal vessels of the central inner retina was reduced, corresponding to nonperfusion areas in the central macula (C, F). Beta-thalassemia was confirmed by genetic testing, clinical features, and family history. The patient underwent hematopoietic stem cell transplantation 3 months earlier. Retinal perfusion should be monitored even after transplantation to prevent irreversible vision loss.

Retinal curvature remodeling following PSR in high myopia quantified by UWF full range SS-OCTA!
Research recently published in quantitatively assessed retinal curvature (RC) and microvascular changes following posterior scleral reinforcement (PSR) by using UWF full range SS-OCTA!
After PSR surgery, all 21 enrolled high-myopic eyes exhibited significant axial shortening and progressive retinal flattening with a consistent decline in mean RC. Notably, a significant correlation between changes in RC and axial length (AL) emerged as early as 1 month postoperatively, suggesting that RC may serve as a sensitive early biomarker for treatment efficacy. Regional alterations in RC demonstrated significant associations with retinal and choroidal flow changes, indicating that mid-peripheral flattening was associated with higher choroidal blood flow, providing evidence for the structural and hemodynamic remodeling following PSR.
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 AI-based algorithm. 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 and quantitative evaluation of surgical outcome.

Real-time intraoperative evaluation of PSR using full-range SS-iOCT!

A 64-year-old female patient underwent successful posterior scleral reinforcement (PSR) in her left eye for high myopia using a digital navigation surgical microscope system ( , Medical). After placement of the scleral band, real-time intraoperative SS-OCT provided dynamic evaluation of the surgical outcome, revealing flattening of the posterior pole and the appearance of fine macular microfolds. Postoperatively, the patient’s axial length decreased from 30.20 mm to 28.19 mm.

Evidence of uveal effusion in HELLP syndrome detected by UWF full range SS-OCTA!
A 36-year-old female patient diagnosed as HELLP syndrome-associated chorioretinopathy with uveal effusion after a cesarean delivery due to preeclampsia presented extensive exudative retinal, choroidal detachments in her both eyes. UWF full range SS-OCTA revealed bilateral choriocapillaris hypointensity, providing direct evidence of choroidal ischemic insult.
This case was published in , authored by Dr. Jiateng Lin from Rongcheng Eye Hospital and Dr. Shancheng Si from Beijing Tsinghua Changgung Hospital Eye Center.
A 400kHz speed swept source OCTA ( , Medical) was used in this case to acquire 24mmx20mm UWF OCTA images for choriocapillaris imaging with AI-based segmentation algorithm.

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.
