Purpose: To assess choroidal perfusion before and after orbital decompression surgery in patients with Graves' ophthalmopathy.
Methods: In this interventional case series, surgical decompression for optic nerve compromise was performed on four eyes of three patients with Graves' disease. Complete ophthalmic examination including visual acuity, color vision, and intraocular pressure assessment were done pre- and postoperatively. High-speed indocyanine green angiography was performed prior to surgery and was repeated one year after surgery.
Results: In all three patients, choroidal perfusion defects were noted pre-operatively in the eyes with the compressive optic neuropathy. At 1 year after orbital decompression surgery, the defects improved or completely resolved. Improved visual acuity and color perception, as well as decreased intraocular pressure, were also noted postoperatively.
Conclusion: Patients with Graves' orbitopathy may have abnormal choroidal perfusion even in the absence of optic neuropathy. Orbital decompression may improve choroidal circulation in these patients.

Numerous conditions, both physiological and pathological, can influence changes in the retinal vascular architecture. In order to be able to highlight pathological aspects of systemic diseases with ocular activity, it is necessary to understand how physiological fluctuations can influence circulation at the retinal level. The present study attempts to evaluate retinal and choroidal vascular and structural changes in healthy female subjects over the course of a menstrual cycle using OCT-A.

Purpose: When performed for clinically significant carotid artery stenosis (CAS), the long-term impact of carotid endarterectomy (CEA) on choroidal and choriocapillaris (CC) circulation was studied using swept-source OCT angiography.
Design: Prospective observational study.
Participants: Patients with clinically significant CAS undergoing unilateral CEA.

Purpose: Anatomical variations in the anterior choroidal artery (AChA) and/or the posterior cerebral artery (PCA) are rare. Hyperplastic AChA is an anatomical variant supplying both the AChA area and the PCA area. In accessory PCA, a hyperplastic AChA supplies part of the PCA territory.

Background: The pathophysiologic mechanisms underlying early-onset myopia remain unclear; in this study, we investigate the pathogenesis by examining the interrelationships between axial length to corneal curvature radius ratio ( ) and choroidal blood flow.
Methods: This cross-sectional study included 202 eyes from myopic children, categorized into 141 eyes with mild myopia, 47 eyes with moderate myopia, and 14 eyes with high myopia. Optical coherence tomography angiography (OCTA) was used to measure choroidal blood flow perfusion within a 6 mm × 6 mm area of the macular region, divided into nine subareas based on ETDRS partitioning: macular fovea, nasal side 1, superior 1, temporal side 1, inferior 1, nasal side 2, superior 2, temporal side 2, and inferior 2.

Purpose: To assess the retinal and choroidal microvascular changes in patients with benign essential blepharospasm (BEB) and to investigate the factors that may be effective on microvascularity.
Methods: This study included patients with BEB and healthy controls. All participants underwent a comprehensive examination followed by optical coherence tomography angiography (OCTA).
