[Retracted] Study on Factors Associated with High Myopia CNV in Aqueous Humor and Serum

Abstract

Objective. The objective is to investigate the relationship and correlation between PEDF and TGF-β in aqueous humor and serum and high myopia CNV lesions. Methods. For each group of patients (namely, group A: patients with high myopia CNV (mCNV); group B: patients with high myopia without CNV; group C: patients with CNV caused by other eye diseases; and group D (control group): patients with simple cataract (without CNV and high myopia)), 20 patients were collected. A total of 40 patients have been collected since the beginning of the study in December 2020, including 7 patients in group A, 13 patients in group B, 10 patients in group C, and 10 patients in group D. Serum and aqueous humor samples were collected, and PEDF and TGF-β levels in serum and aqueous humor were detected by enzyme-linked immunosorbent assay (ELISA). SPSS 26.0 statistical software was used to process the data. Independent sample t-test was used to compare the data of the same factor in the same group between serum and aqueous humor. Comparisons of the same factors between different groups were performed using a one-way analysis of variance (ANOVA). Correlation analysis was conducted by the Pearson correlation coefficient test. P < 0.05 indicated that the difference was statistically significant. Results. There were no significant differences in age, gender, and course of disease among all groups ( P > 0.05 ). The concentration of PEDF in aqueous humor in group A and group C was higher than that in group B and group D. There was no significant correlation between serum PEDF content and the above-mentioned diseases. The concentration of TGF-β in aqueous humor in groups A, B, and C was significantly higher than that in group D. However, there was no significant correlation between TGF-β content in serum and the above-mentioned diseases. There was no significant correlation between aqueous humor and serum PEDF. There was no significant correlation between the content of TGF-β in aqueous humor and serum. Conclusion. TGF-β in aqueous humor may be involved in the development of high myopia and intraocular CNV disease. However, PEDF in aqueous humor may be involved in the development of intraocular CNV disease and has no significant correlation with high myopia. At the same time, TGF-β and PEDF in serum had no significant correlation with high myopia and intraocular CNV disease. There was no significant correlation between the concentrations of TGF-β and PEDF in aqueous humor and serum.

Myopiában kialakuló chorioidea neovascularisatio

“…Myop CNV patogenezise nem teljesen ismert. Prekurzor lézió kialakulása indítja meg a folyamatot (hátsó pólus atrófia, elongáció), a pigment epithel -Bruch-membrán -choriocapillaris komplexben elváltozások jönnek létre (11). Choroidea erek mennyiségének relatív csökkenése és/vagy patológiás elváltozások kialakulása relatív hypoxiát eredményez a PE területén és a gliasejtekben, amelynek következtében a VEGF szintje megemelkedik (an-4.…”

Biomarker Signature in Aqueous Humor Mirrors Lens Epithelial Cell Activation: New Biomolecular Aspects from Cataractogenic Myopia

“…TGFβ expression can explain the epithelial to mesenchymal transition (EMT) and the expression of α-smooth muscle actin (α-SMA) as well as the scleral ECM makeover observed in LEC from myopic eyes [ 13 , 14 , 15 , 16 ]. Local (AH) and systemic (plasma) associations between the increased levels of TGF-βs, matrix metalloproteinase (MMP), and tissue inhibitors of MMP (TIMP) have been observed in myopic patients [ 15 , 17 , 18 , 19 ]. Other studies have confirmed TGFβ involvement in AH from high myopic patients and PEDF involvement in intraocular CNV lesions, but circulating TGFβ and PEDF had no significant correlation with high myopia or intraocular CNV disease [ 20 ].…”

Effects of endogenous dopamine induced by low concentration atropine eye drops on choroidal neovascularization in high myopia mice

“…Bleeding and edema caused by CNV are the common complications leading to visual function loss in patients with high myopia, which greatly reduces the vision-related quality of life of patients. Without treatment, the vision of most patients with high myopic CNV will further deteriorate and may lead to blindness [2] . The vascular endothelial growth factor A (VEGFA) secreted by retinal pigment epithelium cells (RPE), an important subtype of VEGF, is involved in the genesis and development of CNV [3] .…”
