Comparative analysis of optical coherence tomography angiography findings before and after flow-diverting stent treatment covering the ophthalmic artery origin in the management of paraclinoid aneurysms.

Purpose: Flow-diverter stents (FDSs) are being increasingly used for endovascular treatment of paraclinoid aneurysms. However, their impact on ophthalmic artery (OA) flow and retinal microvasculature remains unclear. Using optical coherence tomography angiography (OCTA), we evaluated the microvascular changes after FDS placement on the OA.

Assessment of Ocular Magnification in Relation to Biometric Parameters and Measurement Techniques: A Prospective Study.

Purpose: The aim of this study was to evaluate the effects of factors such as axial length (AL), spherical equivalent (SE), and keratometry (K) on longitudinal and lateral magnification and their impact on Bruch's membrane opening (BMO)-fovea distance and central foveal thickness (CFT) measurements.

Methods: This prospective cross-sectional study included 437 eyes of 437 healthy participants aged 18 to 50 years with best corrected visual acuity of 20/20 or better. Participants were divided into three groups according to their refractive status: myopia (< -0.
