Retinal curvature remodeling following PSR in high myopia quantified by UWF full range SS-OCTA!
Research recently published in <Photodiagnosis and Photodynamic Therapy> 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 BMizar, TowardPi 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.
