Abstract
PURPOSE To evaluate the retinal and choroidal vascular structures in patients with anxiety disorders. METHODS Thirthy-four eyes of 34 patients who were diagnosed with any anxiety disorders were compared with 32 eyes of 32 age- and sex-matched controls. Central macular thickness (CMT), foveal vascular zone (FAZ) area, total retinal vascular densities of superficial and deep capillary plexus (VDSCP, VDDCP), outer retinal and choriocapillary layers (ORL, CCL) blood flow rates, central subfoveal choroidal thickness (SFCT) and choriodal vascularity index (CVI) were evaluated with optical coherence tomography angiography (OCT-A) and enhanced depth imaging optical coherence tomography (EDI-OCT). RESULTS No statistical differences were found between the study and control groups in terms of CMT, FAZ area, VDSCP, VDDCP, ORL and CCL blood flow rates. The mean SFCT was 346.26 ± 64.26 µm in patients with anxiety disorder and was found to be statistically significantly thicker than the control group (319.56 ± 37.19 µm) (p = 0.042). Besides, CVI was significantly lower in the study group (71.09 ± 2.64 vs 73.13 ± 3.31, p = 0.008). CONCLUSION In people with anxiety disorders, the SFCT was found to be thicker and CVI was found to be lower than normal subjects. Although anxiety and stress are important factors in central serous chorioretinopathy, multifactorial factors, including ocular factors, play a role in the pathophysiology of the disease. There is a need for prospective studies with larger series on the subject.

Comparisons of choroidal thickness and volume in eyes with central serous chorioretinopathy to that of control eyes determined by ultra-widefield optical coherence tomography. Graefes Arch Clin Exp Ophthalmol 2024; 262:2135-2143. [PMID: 38413447 DOI: 10.1007/s00417-024-06409-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 01/20/2024] [Accepted: 02/02/2024] [Indexed: 02/29/2024] Open
Abstract
PURPOSE To compare choroidal thickness and volume in eyes with central serous chorioretinopathy (CSC) and healthy control eyes over a wide area of the fundus using ultra-widefield optical coherence tomography (UWF-OCT). METHODS Thirty-three eyes of 29 patients with CSC and 36 eyes of 21 healthy controls were examined retrospectively. Choroidal images were obtained with a prototype UWF-OCT device with a field of view of 105° or approximately 31.5-mm wide by 10.9-mm deep. Choroidal thickness and volume were measured in the images of 12 radial scans (every 15°) from the horizontal scan. The "new index" of the extent of focal choroidal protrusion was defined as the maximum steepness of choroidal thickness (MSCT). RESULTS Choroidal volume in CSC eyes was significantly larger than in control eyes within the central 50° (P < 0.001). However, there was no significant difference in choroidal volume in the peripheral 50 to 105° (P = 0.071). The MSCTs were significantly steeper in CSC eyes than in control eyes at scan lines 1, 6, 7, 8, and 10 (P < 0.01, P < 0.001, P < 0.05, P < 0.01, P < 0.05). CONCLUSIONS The choroid in CSC eyes was thickened only at the posterior pole, and its protrusion was significant mainly in the vertical direction. Focal choroidal thickening at the posterior pole, which we speculate includes congenital scleral changes, may affect the pathophysiology of CSC.

Abstract
Purpose To investigate the choroidal vascularity index (CVI) and choroidal structural changes in children with nephrotic syndrome. Methods This was a cross-sectional study involving 45 children with primary nephrotic syndrome and 40 normal controls. All participants underwent enhanced depth imaging-optical coherence tomography examinations. An automatic segmentation method based on deep learning was used to segment the choroidal vessels and stroma, and the choroidal volume (CV), vascular volume (VV), and CVI within a 4.5 mm diameter circular area centered around the macular fovea were obtained. Clinical data, including blood lipids, serum proteins, renal function, and renal injury indicators, were collected from the patients. Results Compared with normal controls, children with nephrotic syndrome had a significant increase in CV (nephrotic syndrome: 4.132 ± 0.464 vs. normal controls: 3.873 ± 0.574; P = 0.024); no significant change in VV (nephrotic syndrome: 1.276 ± 0.173 vs. normal controls: 1.277 ± 0.165; P = 0.971); and a significant decrease in the CVI (nephrotic syndrome: 0.308 [range, 0.270-0.386] vs. normal controls: 0.330 [range, 0.288-0.387]; P < 0.001). In the correlation analysis, the CVI was positively correlated with serum total protein, serum albumin, serum prealbumin, ratio of serum albumin to globulin, and 24-hour urine volume and was negatively correlated with total cholesterol, low-density lipoprotein cholesterol, urinary protein concentration, and ratio of urinary transferrin to creatinine (all P < 0.05). Conclusions The CVI is significantly reduced in children with nephrotic syndrome, and the decrease in the CVI parallels the severity of kidney disease, indicating choroidal involvement in the process of nephrotic syndrome. Translational Relevance Our findings contribute to a deeper understanding of how nephrotic syndrome affects the choroid.

[PMID: 38373920 PMCID: PMC10875800 DOI: 10.1186/s12886-024-03338-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Accepted: 02/02/2024] [Indexed: 02/21/2024] Open
Abstract
AIMS To find potential relation between retrobulbar vessels and fundus microvessels and to detect sensitive and effective clinical indicators in predicting the progress of diabetic retinopathy (DR), ocular hemodynamics were measured using superb microvascular imaging (SMI) and ultrawide-field optical coherence tomography angiography (UWF-OCTA). METHODS Observational, cross-sectional study evaluating ocular hemodynamics in patients with DR by SMI (Aplio i900, Canon Medical) and UWF-OCTA (BM-400 K BMizar, Tupai Medical Technology). The peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistive index (RI) of the central retinal artery (CRA), posterior ciliary artery (PCA), and ophthalmic artery (OA) were measured by SMI. UWF-OCTA evaluated the fundus vascular parameters. A correlation analysis was used to determine the correlation between SMI and UWF-OCTA parameters. RESULTS One hundred thirty-nine eyes of 139 diabetic patients were included: 29 without DR (NDR), 36 with mild to moderate nonproliferative DR (M-NPDR), 37 with severe NPDR (S-NPDR), and 37 with proliferative DR (PDR). PSV and EDV of retrobulbar vessels decreased from NDR to S-NPDR while increasing PDR. RI of OA showed a decreasing trend in the progression of DR, but other vessels didn't show the same trend. ROC curve analysis showed that CRAPSV, CRAEDV, PCAEDV, OAPSV, and OAEDV had diagnostic value distinguishing M-NPDR and S-NPDR. The correlation analysis observed a significant association between the SMI parameters of CRA and PCA and UWF-OCTA parameters. CRA hemodynamics were more associated with fundus vascular parameters, especially the retina, in the NDR group than in the M-NPDR group. In contrast, PCA consistently correlated with fundus vascular parameters, especially in the choroid, from the NDR to the M-NPDR group. However, OA showed a poor correlation with OCTA parameters. CONCLUSION The velocity of retrobulbar vessels, mainly the CRA, may serve as a valuable predictor for assessing the progress of DR. The use of SMI in diabetic patients may help identify patients at risk of developing retinopathy.

[PMID: 37498843 PMCID: PMC10374115 DOI: 10.1371/journal.pone.0289186] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Accepted: 07/13/2023] [Indexed: 07/29/2023] Open
Abstract
PURPOSE To evaluate the choroidal vascularity index (CVI) in different types of central serous chorioretinopathy (CSC), healthy control eyes, and fellow eyes. METHODS Relevant studies published up to January 2023 were identified by searching multiple databases, including PubMed, Embase, Web of Science, Cochrane Library, and China National Knowledge Infrastructure (CNKI). Studies investigating the difference in CVI between CSC and control eyes were included. Data from these studies were analyzed using Stata (version 17) software. Weighted mean difference (WMD) and 95% confidence interval (95%CI) were calculated for the CVI in CSC eyes, control eyes, and fellow eyes. RESULTS The meta-analysis included 15 studies, with 213 acute CSC eyes, 153 chronic CSC eyes, 92 uncategorized CSC eyes, 40 resolved CSC eyes, 409 eyes of normal healthy controls, and 318 fellow eyes. The result revealed that CVI was higher in acute CSC eyes (WMD = 5.40, 95%CI = 2.36-8.44, P = 0.001) compared to control eyes. Also, CVI in chronic CSC eyes was higher than in control eyes (WMD = 1.26, 95%CI = 0.03-2.49, p = 0.046). The fellow eyes of acute CSC had a higher CVI when compared to control eyes (WMD = 2.53, 95%CI = 0.78-4.28, p = 0.005). There was no significant difference in CVI between acute and chronic CSC eyes (WMD = 0.75, 95%CI = -0.31-1.82, P = 0.167). In the sub-analysis based on the area selected for CVI calculation, the WMDs in the whole image subgroups were lower than the main analysis for the comparisons of fellow eyes of acute CSC and control eyes, acute CSC eyes and control eyes, and acute CSC eyes and fellow eyes. In the macular area subgroups, the WMDs were higher than in the whole image subgroups, suggesting a potential regional variation of CVI in CSC eyes. CONCLUSIONS The results demonstrated that CVI is increased in CSC eyes and fellow eyes of acute CSC. There is no significant difference in CVI between acute and chronic CSC eyes. The area selected for CVI calculation can influence the outcome, which requires further clinical research to clarify.
