Summary: The advancement of optical coherence tomography (OCT) technology has greatly improved the analysis of choroidal morphology and physiology, especially with the use of enhanced depth imaging OCT and swept-source OCT. This has led to a better understanding of choroidal disorders in retinal and choroidal diseases.

Summary: Cigarette smoking is associated with increased SFCT in patients with CSC. Thicker choroid in smoking CSC patients may play an important role in modulating the disease. Age, SE, and past smoking history are key factors influencing SFCT.

Summary: This study evaluated the choroidal vascularity index (CVI) in central serous chorioretinopathy (CSC) and found that CVI is increased in acute CSC eyes and fellow eyes. There was no significant difference in CVI between acute and chronic CSC eyes. The area selected for CVI calculation may influence the outcomes of the study and requires further research.

Summary: The purpose of this study was to investigate the relationship between scleral thickness and choroidal structure in CSC eyes. The results showed a significant positive correlation between scleral thickness and the luminal/stromal ratio in the posterior choroid. Scleral thickness had a stronger correlation with the ratio compared to subfoveal choroidal thickness.

Summary: This study evaluated the choroidal and photoreceptor thickness in highly myopic eyes and found that photoreceptor thickness, age, and axial length are significant predictors of poorer visual acuity. It also found that thinner choroidal thickness does not directly correlate with poorer vision.

Summary: This study found that patients with XFS had decreased choroidal vascularity in the macular and peripapillary regions, while unaffected fellow eyes may show vascular changes in the peripapillary choroid.

Summary: The choroid is responsible for providing blood flow to the ocular tissues, and choroidal thickness has been suggested as a biomarker for choroidal health. However, the utility of choroidal thickness in glaucoma is still debatable due to conflicting pilot studies, lack of standardized analysis methods, small sample sizes, and a lack of controlled studies.

Summary: The relationship between choroidal thickness profile and clinical outcomes after anti-VEGF treatment in PCV was investigated. Results suggest that baseline nPCT and SFCT/nPCT ratio could be a good biomarker reflecting clinical outcomes in PCV after anti-VEGF treatment.

Summary: This study investigates the parameters of optical coherence tomography (OCT) and OCT angiography (OCTA) in patients with neovascular age-related macular degeneration (nAMD) and macular neovascularization (MNV) types 1, 2, and 3. The results showed significant differences in CVI, CMT, and ORCCFA between MNV 1 and the other two groups. CVI was significantly different between MNV 1 and healthy controls and between MNV 1 and MNV 2. ORCCFA and CMT were significantly different between MNV 1 and MNV 2. There was no statistically significant difference in subfoveal choroidal thickness (SFCT) among the three groups.

Summary: This study proposes a novel method based on convolutional neural networks for direct estimation of choroidal thickness without the need for segmentation. The experimental results show that this method has great potential for application.

Summary: Enhanced depth imaging optical coherence tomography (EDI-OCT) and swept-source OCT (SS-OCT) are essential tools for studying and managing chorioretinal diseases. Measurement of choroidal thickness (CT) is important for early detection and monitoring of systemic diseases, and advancements in OCT technology have enabled faster and wider imaging of the eye's posterior part.

Summary: The study found that there were increases in SFCT, CVI, LA, SA, and TA in patients with severe carotid stenosis on the 1st day and 1st month after ICA stenting. This suggests that improvement in choroidal thickness and choroidal vascular flow can be observed even in the early period after ICA stenting.

Summary: This study analyzed the relationship between diopter and choroidal thickness in myopic children and found significant differences in choroidal thickness among myopic children. Choroidal thickness was positively correlated with diopter and negatively correlated with axial length. Therefore, choroidal thickness is considered an important indicator for evaluating the progression of myopia.

Summary: This study aimed to investigate the choroidal thickness in patients with moderate diabetic retinopathy and its correlation with retinal thickness compared to healthy subjects. The results showed that retinal thickness was higher in certain areas in the diabetic group, but choroidal thickness did not differ between the groups. Additionally, age was found to have an impact on retinal thickness and choroidal thickness.

Summary: This study evaluated retinal and choroidal alterations in eyes with inactive ocular sarcoidosis using OCTA and EDI-OCT, and found significant differences compared to healthy individuals. The results suggest that OCTA and EDI-OCT imaging may be useful for monitoring changes in ocular sarcoidosis.
