Association of macular outward scleral height with axial length, macular choroidal thickness and morphologic characteristics of the optic disc in Chinese adults. Eye (Lond) 2024; 38:923-929. [PMID: 37898715 PMCID: PMC10966051 DOI: 10.1038/s41433-023-02804-5] [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: 02/12/2023] [Revised: 10/09/2023] [Accepted: 10/18/2023] [Indexed: 10/30/2023] Open
Abstract
PURPOSE To identify the relationship of macular outward scleral height (MOSH) with axial length (AL), macular choroidal thickness (ChT), peripapillary atrophy (PPA), and optic disc tilt in Chinese adults. METHODS In this cross-sectional study, 1088 right eyes of 1088 participants were enrolled and assigned into high myopia (HM) and non-HM groups. MOSH was measured in the nasal, temporal, superior, and inferior directions using swept-source optical coherence tomography images. The clinical characteristics of MOSH and the association of MOSH with AL, macular ChT, PPA, and tilt ratio were analysed. RESULTS The mean age of participants was 37.31 ± 18.93 years (range, 18-86 years), and the mean AL was 25.78 ± 1.79 mm (range, 21.25-33.09 mm). MOSH was the highest in the temporal direction, followed by the superior, nasal, and inferior directions (all p < 0.001). The MOSH of HM eyes was significantly higher than that of non-HM eyes, and it was positively correlated with AL in the nasal, temporal, and superior directions (all p < 0.001). Macular ChT was independently associated with the average MOSH (B = -0.190, p < 0.001). Nasal MOSH was positively associated with the PPA area and the presence of a tilted optic disc (both p < 0.01). Eyes with a higher MOSH in the superior (odds ratio [OR] = 1.008; p < 0.001) and inferior directions (OR = 1.006; p = 0.009) were more likely to have posterior staphyloma. CONCLUSION MOSH is an early indicator of scleral deformation, and it is correlated positively with AL and negatively with ChT. A higher nasal MOSH is associated with a larger PPA area and the presence of a tilted optic disc. Higher MOSH values in the superior and inferior directions were risk factors for posterior staphyloma. CLINICAL TRIAL REGISTRATION The study was registered at www. CLINICALTRIALS gov (Reg. No. NCT03446300).

Abstract
Posterior staphyloma (PS) is considered the hallmark of pathologic myopia and is defined as an outpouching of a circumscribed portion of the eyeball with a radius of curvature smaller than that of the adjacent zone. Although more common in eyes with high myopia, it can affect those without it. The presence of PS is associated with a structurally and functionally worse course of high myopia that can lead to visual disability. Unfortunately, the pathogenesis of PS is unclear so far. Thus, due to the increasing prevalence of myopia which has been further exacerbated by the advent of COVID-19 lockdown, researchers are eager to elucidate the pathogenesis of pathologic myopia and that of its complications, especially PS, which will allow the development of preventive strategies. The aim of this work was to review the morphological characteristics of PS with emphasis on similarities with peripapillary staphyloma and to discuss the pathogenesis of PS considering recent suggestions about that of peripapillary staphyloma.

Abstract
BACKGROUND Studies on the choroid of myopic eyes with posterior staphyloma have shown that choroidal thickness decreased. This retrospective study further analysed the effects of posterior scleral staphyloma on choroidal blood vessels and matrix components compared to non-pathological myopia. METHODS In this cross-sectional study, ninety-one eyes were divided into pathological (posterior staphyloma) and non-pathological myopia. The latter was further divided into three groups (Group 1: 26 mm ≤ axial length; Group 2: 24 mm ≤ axial length < 26 mm; Group 3: 22 mm ≤ axial length < 24 mm). Choroidal thickness, total choroidal area, luminal area, stromal area, and choroidal vascularity index were calculated. RESULTS The CVI in N1, N2, I1, S2 of the posterior staphyloma group were lower than those of group 1 (both P < 0.05). The mean height of posterior staphyloma was associated with mean CT (Pearson correlation: r = -0.578, P = 0.039) but not with the mean CVI in posterior staphyloma group. In all groups, the mean choroidal thickness, total choroidal area, luminal area, and stromal area were significantly associated with axial length (P < 0.001), and the mean choroidal vascularity index was significantly associated with the mean choroidal thickness (P < 0.001). CONCLUSION The choroidal structure of pathological myopia with posterior staphyloma and non-pathological myopia with longer axial length demonstrates alterations in which choroidal vessels are more impaired than the stroma. A lower choroidal vascularity index should be alert to pathological changes for myopia with axial length > 26 mm.

Abstract
PURPOSE Myopic scleral pit (MSP) is a rare physical sign of pathological myopia (PM). The aim of this study was to summarize the clinical characteristics of MSP and analyze its correlation with PM. METHODS Eight cases with PM and MSP were enrolled in this study. Comprehensive ophthalmic examinations, including subjective refraction, slit-lamp biomicroscope, intraocular pressure, fundus photographs, A- and B-scan ultrasonography and spectral-domain optical coherence tomography, were performed. RESULTS All the patients had a long history of PM with visual impairment, long axial length, and myopia-related fundus degeneration. Mean axial length was 31.48 ± 2.17 mm. Mean size of MSP was 0.69 ± 0.29 optic disc diameter (PD). Mean logMAR BCVA was 1.21 ± 0.88 logMAR. Spearman correlation analysis showed that the logMAR BCVA had no correlation with the size of pits (P = 0.34). Fundus examination revealed a focal pale concave located in the sclera exposed area of retinal choroid atrophy was found in all cases. OCT showed a deep scleral pit where the retinal choroid was thin or absent, without retinal sensory detachment or sensory defect. CONCLUSIONS This study identified a rare scleral lesion in all eight individuals with PM, which was termed "myopic scleral pit". This phenomenon is different from focal choroidal excavation and posterior staphyloma.

Abstract
PURPOSE To investigate different modes of foveal regeneration after the closure of idiopathic macular hole (IMH) or highly myopic macular hole (HMMH) by vitrectomy with internal limiting membranes peeling or flap techniques. METHODS This retrospective observational study followed 47 IMH and 50 HMMH eyes for at least 6 months. Twenty four IMH and 25 HMMH eyes underwent internal limiting membrane peeling, whereas 23 IMH and 25 HMMH eyes received inverted internal limiting membrane flap technique. Spectral domain optical coherence tomography was used to analyze macular hole closure, foveal microstructures, and excessive gliosis as a foveal "peak-like" protuberance. RESULTS A single procedure closed all IMH (n = 47). For HMMH, the inverted group (n = 25, 100%) closed more macular hole than the peeling group (n = 14, 56.00%) (P < 0.001). Excessive gliosis only occurred in the inverted group, and there was a significant difference (P = 0.005) in incidence between IMH (three in 23 eyes, 13.04%) and HMMH (13 in 25 eyes, 52.00%). The axial length more than 29.985 mm enhanced the risk of excessive gliosis. CONCLUSION The inverted internal limiting membrane flap efficiently treated refractory MHs but was prone to cause excessive gliosis in highly myopic eyes. Excessive elongation of the globe (axial length > 29.985 mm) was linked to excessive gliosis growth.

Abstract
Myopia is a significant global health concern and affects human visual function, resulting in blurred vision at a distance. There are still many unsolved challenges in this field that require the help of new technologies. Currently, artificial intelligence (AI) technology is dominating medical image and data analysis and has been introduced to address challenges in the clinical practice of many ocular diseases. AI research in myopia is still in its early stages. Understanding the strengths and limitations of each AI method in specific tasks of myopia could be of great value and might help us to choose appropriate approaches for different tasks. This article reviews and elaborates on the technical details of AI methods applied for myopia risk prediction, screening and diagnosis, pathogenesis, and treatment.

Impact of peripapillary staphylomas on the vascular and structural characteristics in myopic eyes: a propensity score matching analysis. Graefes Arch Clin Exp Ophthalmol 2023:10.1007/s00417-022-05966-2. [PMID: 36617582 DOI: 10.1007/s00417-022-05966-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Revised: 12/22/2022] [Accepted: 12/27/2022] [Indexed: 01/10/2023] Open
Abstract
PURPOSE To apply propensity score matching to evaluate the impact of peripapillary staphylomas (PPS) on vascular and structural characteristics in the myopic eyes. METHODS This was a prospective, cross-sectional study. Forty-one control eyes and 41 eyes with PPS were analyzed. The eyes were selected using propensity score matching analysis based on the age and axial length. All subjects underwent ophthalmologic examinations for assessing vessel and structure parameters using swept-source optical coherence tomography (SS-OCT), OCT angiography, color fundus photography, and ocular biometry. RESULTS As compared with control eyes, the eyes with PPS had shallower anterior chamber depth (3.61 ± 0.24 mm vs 3.77 ± 0.24 mm, P = 0.004), higher intraocular pressure (IOP) (16.59 ± 2.88 mmHg vs 14.53 ± 2.45 mmHg, P = 0.002), and higher myopic spherical equivalent (- 11.52 ± 3.22D vs - 9.88 ± 2.20D, P = 0.009). while corneal curvature and lens thickness between the two groups were not statistically different. Compared with control eyes, increased macular deep vessel density, reduced macular choriocapillaris and radial peripapillary capillary, and thinning retinal layer, ganglion cell complex, choroidal layer as well as the superior and inferior peripapillary retinal nerve fiber layer were observed in eyes with PPS, apart from larger disc area, parapapillary atrophy area, and degree of disc rotation. Logistic regression analysis revealed that the IOP (P = 0.046), disc rotation (P = 0.003), and average peripapillary choroidal thickness (P = 0.009) were associated with the presence of PPS. CONCLUSION Close association of PPS with exacerbation of myopia and anatomical alterations was observed which not only affected the eye posterior segment but also the anterior segments. We further identified significant reductions in the radial peripapillary capillary and macular choroidal perfusion with the increase in macular deep retinal flow blood of myopic eyes with PPS. Higher IOP, thinner peripapillary choroidal thickness, and rotated optic disc were risk factors for the presence of PPS.

Abstract
Purpose The purpose of this study was to investigate the clinical characteristics of paravascular abnormalities (PVAs) and retinoschisis, and their associations with choroidal thickness (ChT) in young highly myopic (HM) adults. Methods A total number of 645 eyes were included. Paravascular microfolds (PMs), paravascular cystoid spaces (PCs), paravascular lamellar holes (PLHs), and retinoschisis were detected using swept-source optical coherence tomography. Their associations with macular ChT and risk factors were analyzed. Results PMs, PCs, and PLHs were detected in 203 (31.5%), 141 (21.9%), and 30 (4.7%) eyes, respectively. Retinoschisis was found in 50 (7.8%) eyes, 43 (86.0%) of which were located around the retinal vessels surrounding the optic disc. A decreasing trend of macular ChT (P < 0.001) was observed in the eyes with PMs only, with both PCs and PMs, and with PLHs, PCs, and PMs. After adjustments for age, sex, and axial length (AL), the presence of PCs, PLHs, or retinoschisis around the optic disc was negatively associated with macular ChT (all P < 0.05). Eyes with longer AL, incomplete posterior vitreous detachment (PVD), and myopic atrophic maculopathy (MAM) were more likely to have PCs (all P < 0.01) and retinoschisis around the optic disc (all P < 0.05). Conclusions PVAs were observed in approximately one third of the young HM adults in this study. The presence of PCs, PLHs, or retinoschisis around the optic disc was associated with thinner macular ChT. Eyes with longer AL, incomplete PVD, and MAM may be at risk of developing PVAs and retinoschisis around the optic disc. Translational Relevance PCs, PLHs, and retinoschisis around the optic disc could serve as early indicators for myopia progression.

Investigation of Macular Structural and Microcirculatory Characteristics of Posterior Staphyloma in High Myopic Eyes by Swept Source Optical Coherence Tomography Angiography. Front Physiol 2022; 13:856507. [PMID: 35464076 PMCID: PMC9022789 DOI: 10.3389/fphys.2022.856507] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Accepted: 03/09/2022] [Indexed: 11/21/2022] Open
Abstract
Purpose: To investigate the characteristics of macular structures and microcirculation of posterior staphyloma (PS) and explored factors related to PS in eyes with high myopia. Methods: There were 114 eyes of 82 patients in this study. Using 1:1 matching of the axial length of myopic eyes, patients were divided into no PS (NPS) and PS groups. Comprehensive ophthalmic examinations were performed on all patients. Structural parameters were acquired using swept source optical coherence tomography (SS-OCT). OCT angiography (OCTA) was used to measure the microcirculation parameters. Generalized estimated equation and linear correlation analysis were used for the statistical analysis. Results: Patients with PS had a thinner retinal thickness (RT) and choroid thickness (CT) (all p < 0.05) in the measurement areas and a significantly lower subfoveal scleral thickness (SFST) (p < 0.001) than those without PS. Retinal deep vascular complex density (DVD) (all p < 0.05) and choriocapillaris perfusion area (CCPA) (all p < 0.001) were significantly lower in the measurement areas of the PS group than in those of the NPS group. There was no significant difference in the retinal superficial vascular density between the two groups. Generalized estimating equation indicated that SFST (B = 0.079, p = 0.001), parafoveal RT (B = −0.162, p = 0.041), foveal CT (B = 0.292, p = 0.013), parafoveal CT (B = −0.157, p = 0.023), foveal CCPA (B = 0.691, p = 0.003) and parafoveal CCPA (B = −0.026, p = 0.004) were significantly correlated with PS. Age (r = −0.323, p = 0.001), spherical equivalent refraction (SER) (r = 0.289, p = 0.004), subfoveal CT (r = 0.398, p < 0.001), foveal DVD (r = 0.346, p < 0.001), foveal CT (r = 0.429, p < 0.001), and foveal CCPA (r = 0.387, p < 0.001) were strongly correlated with SFST. Conclusions: The macular structures and microcirculation in the PS group were different from those in the NPS group. SFST, CT, and CCPA were significantly correlated with PS. Lower SFST in PS was correlated with abnormalities of CT and microcirculation.

Abstract
Myopia is the most common type of refractive errors characterized by excessive elongation of the ocular globe. With the increasing prevalence of myopia, improved knowledge of factors involved in myopia development is of particular importance. There are growing evidence suggesting that the choroid plays an important role in the regulation of eye growth and the development of myopia. Studies have demonstrated that thinning choroid is a structural feature of myopia, with a negative correlation between choroidal thickness and axial length, suggesting that the change in choroidal thickness may be a predictive biomarker for long-term changes in ocular elongation. Given the fact that the choroid is primarily a vascular structure capable of rapidly changing blood flow, variations of choroidal thickness might be primarily caused by changes in choroidal blood flow. Considering that hypoxia is associated with myopia and choroidal blood flow is the main source of oxygen and nourishment supply, apart from the effect on myopia possibly by changing choroidal thickness, decreasing choroidal blood flow may contribute to scleral ischaemia and hypoxia, resulting in alterations in the scleral structure and thus leading to myopia. This review aims to provide an overview of recent work exploring the influence of the choroid on myopia from perspectives of choroidal thickness and blood flow, which may present new predictive indicators for the onset of myopia and new targets for the development of novel therapeutic approaches for myopia.

Associations of refractive errors and retinal changes measured by optical coherence tomography: A systematic review and meta-analysis. Surv Ophthalmol 2021; 67:591-607. [PMID: 34343537 DOI: 10.1016/j.survophthal.2021.07.007] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 07/26/2021] [Accepted: 07/27/2021] [Indexed: 12/15/2022]
Abstract
Studies reporting alteration in retinal thickness using optical coherence tomography (OCT) have been performed in different populations with various degrees of refractive error, producing inconsistent results. Therefore, we performed a meta-analysis to evaluate the alterations in retinal OCT measurements in myopic and hyperopic patients compared to controls. Evaluation of different retinal layers' thickness may have significance for developing novel approaches for preventing, diagnosing, and treating refractive errors and their complications. We searched PubMed and EMBASE to identify articles that reported OCT measurements of different retinal layers and regions, including macular, foveal, parafoveal, perifoveal, foveolar, ganglion cell complex (GCC), retinal nerve fiber layer (RNFL), peripapillary retinal nerve fiber layer (pRNFL), and ganglion cell and inner plexiform layer (GC-IPL) thickness in addition to macular volume, and optic disc area in myopes and hyperopes comparing their differences with controls. We applied either a fixed-effects or random-effects model for the meta-analysis of these differences based on the assessed heterogeneity level. Furthermore, subgroup analyses and metaregression, as well as publication bias and quality assessment, were conducted for the eligible studies. Forty-seven studies with a total of 12223 eyes, including 8600 cases and 3623 non-cases, are included in this meta-analysis. Our results showed that, in comparison to controls, highly myopic eyes had a significantly lower value for mean macular thickness, macular GCC, macular GC-IPL, parafoveal, perifoveal, foveal, foveolar, RNFL, and pRNFL thickness. Compared to controls, moderately myopic eyes showed a significantly thinner mean macular GCC layer and pRNFL. On the other hand, hyperopic eyes had significantly thicker average pRNFL than controls. Several other significant differences were also observed in various regional analyses. The findings of the current study affirm the retinal OCT measurement differences between myopic and hyperopic eyes compared to controls, emphasizing OCT measurements' advantages as potential biomarkers of ocular pathologies.

Abstract
Pathologic myopia is a major cause of visual impairment worldwide. Pathologic myopia is distinctly different from high myopia. High myopia is a high degree of myopic refractive error, whereas pathologic myopia is defined by a presence of typical complications in the fundus (posterior staphyloma or myopic maculopathy equal to or more serious than diffuse choroidal atrophy). Pathologic myopia often occurs in eyes with high myopia, however its complications especially posterior staphyloma can also occur in eyes without high myopia. Owing to a recent advance in ocular imaging, an objective and accurate diagnosis of pathologic myopia has become possible. Especially, optical coherence tomography has revealed novel lesions like dome-shaped macula and myopic traction maculopathy. Wide-field optical coherence tomography has succeeded in visualizing the entire extent of large staphylomas. The effectiveness of new therapies for complications have been shown, such as anti-VEGF therapies for myopic macular neovascularization and vitreoretinal surgery for myopic traction maculopathy. Myopia, especially childhood myopia, has been increasing rapidly in the world. In parallel with an increase in myopia, the prevalence of high myopia has also been increasing. However, it remains unclear whether or not pathologic myopia will increase in parallel with an increase of myopia itself. In addition, it has remained unclear whether genes responsible for pathologic myopia are the same as those for myopia in general, or whether pathologic myopia is genetically different from other myopia.

Prognostic Factors for Axial Length Elongation and Posterior Staphyloma in Adults With High Myopia: A Japanese Observational Study. Am J Ophthalmol 2021; 225:76-85. [PMID: 33309693 DOI: 10.1016/j.ajo.2020.11.023] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Revised: 11/26/2020] [Accepted: 11/30/2020] [Indexed: 01/18/2023]
Abstract
PURPOSE To identify prognostic factors for axial length (AL) elongation and incidence of posterior staphyloma (PS) in adult Japanese patients with high myopia. DESIGN Retrospective, observational cohort study. METHODS Six-year follow-up data for 345 patients (620 eyes with AL ≥ 26.5 mm and spherical equivalent [SE] ≤- 8.00 diopters) admitted to the Tokyo Medical and Dental University Hospital from 2007 to 2017 were analyzed retrospectively. Main outcome measures were change in AL from baseline, factors associated with AL, categorization of eyes with high myopia, factors associated with incidence of PS, and impact of PS on myopic maculopathy and visual function. RESULTS The mean annual increase in AL was 0.03 mm. Presence of optic nerve disc conus (P = .025), steeper corneal curvature, lower SE, and decreased choroidal thickness (CT) (all P < .001) were associated with increased AL in univariate and multivariate analyses. Younger age (P = .003) and no use of intraocular pressure-lowering medications (P = .046) were associated with increased AL. Eyes with high myopia were categorized using factor analysis as associated with glaucoma, severe pathologic myopia, and mild-to-moderate pathologic myopia. Older age, increased AL, glaucoma, and choroidal thinning (all P ≤ .001) were identified as significant risk factors for the incidence of PS in univariate and/or multivariate analyses. Incidence of PS was a precursor for myopic maculopathy and visual field defects. CONCLUSIONS Optic nerve disc conus, steeper corneal curvature, lower SE, decreased CT, and no use of intraocular pressure-lowering medications were prognostic factors for increased AL. Older age, increased AL, glaucoma, and decreased CT were prognostic factors for PS.

Abstract
To explore the pathogenesis of high myopia (HM) using quantitative proteomics. The aqueous humor of patients with simple nuclear cataract and nuclear cataract complicated with HM (hereinafter referred to as "C" and "HM" groups, respectively) were collected. The isobaric tags for relative and absolute quantitation (iTRAQ)-based liquid chromatography-tandem mass spectrometry (LC-MS/MS) proteomics approach was employed to explore differentially expressed proteins (DEPs). Bioinformatics was used to interpret the proteomic results. Furthermore, the plasminogen (PLG) protein was confirmed by enzyme-linked immunosorbent assay (ELISA) as the candidate biomarker for HM through a receiver operating characteristic curve analysis. The study showed 32 upregulated and 26 downregulated proteins. The gene ontology analysis demonstrated that 58 DEPs corresponded to 325 biological processes, 33 cell components, and 45 molecular functional annotations. The Kyoto Encyclopedia of Genes and Genomes analysis showed that the upregulated DEPs were highly enriched in the coagulation and complement cascades, consistent with the gene set enrichment analysis. Our data suggested that some DEPs might be hallmarks of the development of HM. ELISA confirmed that the PLG expression levels were significantly upregulated in HM. This was a new study investigating alterations in protein levels and affected pathways in HM using iTRAQ-based quantitative proteomics. Our study provided a comprehensive dataset on overall protein changes and shed light on its potential molecular mechanism in human HM.

Abstract
Purpose To evaluate the factors associated with asymmetric myopic atrophic maculopathy (MAM) in highly myopic patients. Methods We enrolled highly myopic patients with asymmetric MAM according to the atrophy, traction, and neovascularization (ATN) classification. The results of color fundus photography, optical coherence tomography (OCT), OCT angiography, and corneal visualization Scheimpflug technology (Corvis ST tonometry) were reviewed. The association between inter-eye differences in clinical features and MAM grading was analyzed using logistic regression analysis. Results Among the 72 eyes of 36 patients 61.0 ± 9.3 years of age, 9, 33, 17, and 13 eyes had A1, A2, A3, and A4, respectively. The mean axial length was 30.44 ± 1.92 mm, and there was no significant difference between eyes with less severe and more severe MAM. The inter-eye differences in MAM grading were associated with the inter-eye differences in the presence of Bruch's membrane defects (P = 0.014), ellipsoid zone disruption (P = 0.013), vessel density of the deep retinal layer (P = 0.022), foveal avascular zone circularity (P = 0.012), foveal avascular zone area (P = 0.049), flow area of the choriocapillaris (P = 0.013), vessel diameter (P = 0.045), and fractal dimension (P = 0.015). No Corvis ST parameter was statistically significant. A higher difference in the choriocapillaris flow area (P = 0.013; adjusted odds ratio = 1.10 [1.02–1.18]) remained associated with higher inter-eye differences in MAM grading in the multivariable regression. Conclusions A smaller choriocapillaris flow area was associated with more severe MAM, suggesting that vascular factors play pivotal roles in MAM.

Abstract
Purpose To investigate the levels of transforming growth factor-β (TGF-β) in human aqueous humor (AH) and plasma (PL) of patients with myopia, and verify whether there is an association between these levels and their association with axial length (AL). Methods Thirty-eight myopic patients who received intraocular collamer lens (ICL) implantation were enrolled in this cross-sectional study. Patients were divided into three groups based on AL with cut-off points of 26 and 28 mm. AH and PL samples were obtained during ICL implantation surgery. The levels of TGF-β1, TGF-β2, and TGF-β3 in the AH and PL samples were measured using Luminex xMAP Technology kits (Milliplex xMAP kits). The protein levels of TGF-βs in both AH and PL samples and their relationships with AL were analyzed. Results In all, 38 patients (59 eyes) were enrolled and divided into the three groups: group A contained 7 people (10 eyes), group B contained 22 people (37 eyes), and group C contained 9 people (12 eyes). In the AH group, we detected TGF-β1 (P50: 19.97 pg/mL), TGF-β2 (2446.00 pg/mL), and TGF-β3 (26.33 pg/mL); in PL, these concentrations were 8984.00, 523.44, and 210.47 pg/mL, respectively. The levels of TGF-β1 and TGF-β3 in AH were positively associated with AL. None of the three isoforms in PL were related to those in AH or to AL. Conclusions The levels of TGF-β1 and TGF-β3 in AH were more strongly associated with the severity of myopia than the types of TGF-β in PL.

Abstract
Objective To investigate the microvasculature and structural characteristics of the eyes of myopic patients and their association with posterior staphyloma (PS). Methods This was a retrospective, case-control study comprising of 106 eyes from 72 individuals. Using 1:1 matching of axial length (AL) of their eyes, patients were allocated into a PS group or no posterior staphyloma (NPS) group. All patients were examined using ultra-widefield fundus imaging, optical coherence tomography angiography, and ocular biometry to acquire microvasculature and microstructure parameters. Results The anterior chamber depth (ACD) of the PS group was significantly different from that of the NPS group (3.56 mm vs 3.76 mm, P < 0.001), as was 1ens thickness (3.72 mm vs 3.57 mm, P = 0.005) and spherical equivalent (SE)(-10.11D vs -8.80D, P = 0.014). The PS group had reduced choriocapillaris flow, subfoveal choroidal thickness (SFCT), and a thinner retinal layer compared with the NPS group. No difference in retinal blood flow between the two groups was observed. The PS group exhibited a smaller disc area (15082.89 vs 17,043.32, P = 0.003) and angle α between temporal retinal arterial vascular arcades (113.29°vs 128.39°, P = 0.003), a larger disc tilt ratio (1.41 vs 1.24, P < 0.001) and parapapillary atrophy (PPA) area (13840.98 vs 8753.86, P = 0.020), compared with the NPS group. Multivariate regression analysis indicated that disc tilt ratio (P = 0.031) and SFCT (P = 0.015) were significant predictors of PS. In addition, PS (P = 0.049), AL (P = 0.003), corneal refractive power (P < 0.001), ACD (P = 0.022), relative lens position (P = 0.045), and disc area (P = 0.011) were significant predictors of SE. Conclusions PS was found to be closely linked to a reduction in choriocapillaris perfusion and anatomical abnormalities including posterior and anterior segments. Furthermore, PS exacerbated the progression of myopia. Supplementary Information The online version contains supplementary material available at 10.1007/s00417-020-05057-0.

Abstract
Background To compare different clinical and Spectral-Domain Optical Coherence Tomography (SD-OCT) features of high myopic eyes with Stickler syndrome (STL) with matched controls. Methods Patients with genetically confirmed STL with axial length ≥ 26 mm and controls matched for axial length were included. The following data were obtained from SD-OCT scans and fundus photography: choroidal and retinal thickness (respectively, CT and RT), peripapillary atrophy area (PAA), presence of posterior staphyloma (PS). Results Twenty-six eyes of 17 patients with STL and 25 eyes of 19 controls were evaluated. Compared with controls, patients with STL showed a greater CT subfoveally, at 1000 μm from the fovea at both nasal and temporal location, and at 2000 and 3000 μm from the fovea in nasal location (respectively, 188.7±72.8 vs 126.0±88.7 μm, 172.5±77.7 vs 119.3±80.6 μm, 190.1±71.9 vs 134.9±79.7 μm, 141.3±56.0 vs 98.1±68.5 μm, and 110.9±51.0 vs 67.6±50.7 μm, always P< 0.05). Furthermore, patients with STL showed a lower prevalence of PS (11.5% vs 68%, P< 0.001) and a lower PAA (2.2±2.1 vs 5.4±5.8 mm2, P=0.03), compared with controls. Conclusions This study shows that high myopic patients with STL show a greater CT, a lower PAA and a lower prevalence of PS, compared with controls matched for axial length. These findings could be relevant for the development and progression of myopic maculopathy in patients with STL.

Abstract
To assess the m6A methylome in the anterior capsule of the lens of high myopia patients. MeRIP-seq and RNA-seq were performed to identify differences in the m6A methylomes and gene expression between anterior capsule of the lens of simple nuclear cataract patients (N) and nuclear cataract patients with high myopia (G). Expression of m6A-related enzymes was confirmed by quantitative real-time-PCR. ALKBH5 was downregulated in G. The observed m6A peak was identical to the conserved RRACH gmotif and was markedly correlated with two distinct coordinates. Differentially methylated genes were enriched in some pathways regulating the formation of extracellular matrix. These findings suggest that upregulation of m6A methylation may change fundus anatomy by regulating the composition of the extracellular matrix through encoding protein.

Abstract
PURPOSE To describe features of posterior staphylomas in nonhighly myopic eyes with retinitis pigmentosa (RP). METHODS The retrospective observational case series study included patients with RP and an axial length of <26.5 mm and searched for eyes with posterior staphylomas. All study participants underwent fundus photography and optical coherence tomography. RESULTS The study identified 13 eyes of 7 patients with a narrow macular staphyloma. Mean age was 40.9 ± 17.9 years (range 9-62 years) and mean axial length was 24.90 ± 0.69 mm. The staphyloma edges corresponded to the margin between the retinal atrophic area in the fundus midperiphery and the relatively unaffected fundus center. On vertically orientated optical coherence tomography images, the staphyloma edges showed a slight inward protrusion of the sclera and a ring-like localized choroidal thinning with choroidal rethickening in direction toward the fovea and toward the periphery of the fundus. The upper and lower staphyloma edges did not differ in steepness. The thickness of the subfoveal choroid (138.6 m ± 50.1 µm) was thinner than the normal range after adjusting for age and axial length in all eyes. Two eyes with advanced RP in the macula showed a subfoveal choroidal thickness of 95 µm and 88 µm. CONCLUSION Narrow macular staphylomas can occur in nonhighly myopic eyes with RP and, in contrast to staphylomas in highly myopic eyes, show a less marked thinning of the subfoveal choroid. The occurrence of posterior staphylomas in nonhighly myopic eyes with RP may provide hints to unravel the etiology of posterior staphyloma formation.

Abstract
PURPOSE To characterize the choriocapillaris (CC) in highly myopic eyes with myopic maculopathy, using optical coherence tomographic angiography. METHODS Prospective, clinic-based study of 42 eyes of 38 patients with high myopia (≤-6 diopters and axial length ≥26.5 mm). Myopic maculopathy was graded from fundus photographs according to the Meta-Analysis for Pathologic Myopia classification. Macular 3 × 3 mm en face optical coherence tomographic angiographic images were obtained with swept-source optical coherence tomographic angiography and graded for CC flow impairment as follows: 1) intact CC, 2) focal (<1 mm), and 3) extensive (>1 mm). RESULTS Of the 42 eyes, 17 (39.5%) had tessellated fundus, 20 (46.5%) had diffuse, and 6 (14.0%) had patchy atrophy. Choriocapillaris flow impairment was observed in all eyes with diffuse and patchy atrophy. Even in eyes with tessellated fundus only, CC signal voids were seen in 3 eyes (17.6%). With increasingly severe myopic maculopathy, the pattern of CC flow impairment changed from predominantly focal to predominantly extensive. CONCLUSION Choriocapillaris flow impairment was observed in many highly myopic eyes, even in those with mild fundus changes, and worsened with increasing severity of myopic maculopathy. Longitudinal studies are needed to assess whether CC flow impairment predicts the risk of myopic maculopathy progression.

Abstract
PURPOSE To analyze the hallmark features of pathologic myopia developed in animal models and compare them with those seen in patients. METHODS A literature review was performed to identify animal models that exhibited key features of pathologic myopia, namely posterior staphyloma, myopic maculopathy, lacquer cracks, and choroidal neovascularization, either spontaneously or induced by monocular deprivation. Using imaging modalities, such as optical coherence tomography, confocal scanning laser ophthalmoscopy, fluorescein angiography, and electron microscopy, these features were compared with those found in myopic maculopathy of patients. RESULTS Three types of animals were identified. The LRP2 knockout mice exhibited posterior staphylomas and chorioretinal atrophy at 21 and 60 days after birth, respectively. Retinopathy globe enlarged (rge) chicks and normal lid-sutured chicks developed lacquer cracks and chorioretinal atrophy. Lacquer cracks detected in rge chicks subsequently progressed to patchy chorioretinal atrophy, which is also commonly seen in patients with pathologic myopia. CONCLUSION The LRP2 knockout mice, retinopathy globe enlarged (rge) chicks, and normal lid-sutured chicks exhibit features typical for myopic maculopathy in patients and could serve to further elucidate the pathogenesis of myopic maculopathy.

Choroidal thickness measured with swept source optical coherence tomography in posterior staphyloma strongly correlates with axial length and visual acuity. Int J Retina Vitreous 2019; 5:14. [PMID: 31333879 PMCID: PMC6615153 DOI: 10.1186/s40942-019-0166-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2018] [Accepted: 04/30/2019] [Indexed: 11/10/2022] Open
Abstract
Purpose To measure the choroidal thickness in patients with high myopia from staphyloma using swept source OCT (SS-OCT) in Early Treatment Diabetic Retinopathy Study (ETDRS) fields and compare to normal cohort. The study also evaluated the correlation between choroidal thickness with axial length and best-corrected visual acuity (BCVA). Methods In this prospective cross sectional study, 37 eyes of 20 patients with high myopia from staphyloma and 86 eyes of 43 normal subjects were included. In each eye, horizontal scans centered on the fovea (12 × 9 mm) were performed using SS-OCT (DRI-OCT, Topcon, Japan). Choroidal thickness in 9 ETDRS subfields, including central subfield (CSF) was analyzed and correlated with axial length as well as BCVA. Results The axial length and BCVA in the high myopia from staphyloma group ranged from 25.12 to 33.54 mm (28.4 ± 1.2) and 20/20–20/400, respectively. The choroidal thickness in staphyloma group was 85.53 ± 48.61 μm as compared to 250.24 ± 71.01 μm in the normal group (p < 0.0001). Stepwise regression analysis showed that axial length strongly correlated with decreased choroidal thickness (p < 0.001) in staphyloma group (r = 0.71, r2 = 0.5). Refractive error and BCVA moderately correlated(r = − 0.47; r2 = 0.22) with choroidal thickness (p < 0.001). Conclusion Choroidal thickness in staphyloma (measured with novel technology of SS-OCT) patients is markedly reduced compared to normal controls. In addition, choroidal thickness strongly correlated with axial length of the eye and inversely correlated with visual acuity. This testing modality maybe used as a good predictor of visual acuity in patients with high myopia from staphyloma.

Abstract
The choroid is a vascular tissue which plays a range of critical roles in the normal physiology of the eye, such as supplying the outer retina with oxygen and nutrients and the regulation of intraocular pressure. There is also substantial evidence, particularly from animal studies, that the choroid plays an important role in the regulation of eye growth and the development of common refractive errors like myopia. In recent years, advances in optical coherence tomography technology have improved our ability to image and measure the choroid in the human eye. Research using this technology over the past decade has dramatically improved our knowledge of the normal choroid, and its potential role in the regulation of eye growth and refractive error development. This review aims to provide an overview of recent work examining the normal human choroid, its changes with myopia and the possible role of the choroid in the mechanism regulating eye growth. Studies have demonstrated that choroidal thinning accompanies the development and progression of myopia, and have established a close link between eye growth and choroidal thickness changes. Dramatic thinning of the choroid is seen with high myopia, and associations are also observed between choroidal thinning and reduced vision, and the development of retinal pathology associated with high myopia. In the short-term, environmental factors known to be associated with myopia development and more rapid eye growth typically lead to a thinning of the choroid, whereas factors linked to a slowing of eye growth are typically associated with short-term choroidal thickening. Collectively, these findings suggest that the choroid is an important biomarker of eye growth in the human eye, and additional research to better understand the human choroid is likely to further our knowledge of the signals and pathways regulating eye growth, myopia development and progression.

Using spectral-domain optical coherence tomography to evaluate the type and thickness of interdigitation zone band in adult Chinese. Sci Rep 2018; 8:12253. [PMID: 30115984 PMCID: PMC6095864 DOI: 10.1038/s41598-018-30848-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2018] [Accepted: 08/07/2018] [Indexed: 11/21/2022] Open
Abstract
To study types and thickness of interdigitation zone band in adult Chinese subjects, we conducted a cross-sectional study. The population-based Beijing Eye Study 2011 included 3468 individuals with a mean age of 64.6 ± 9.8 years. 263 people (263eyes) with a mean age of 64.8 years were randomly selected cases without macular diseases included in the study. A detailed ophthalmic examination was performed including SD-OCT for measurement of the thickness of interdigitation zone band. There are two types of interdigitation zone band; the type1 which can distinguish RPE–BM complex in 170 eyes; and the Type 2 which the two layers merged involved 93 eyes. In type1, the mean thickness of the interdigitation zone band was significantly thicker in the foveal center (16.46 ± 2.92 μm), then nasal macular region (16.19 ± 2.69 μm), temporal macular region (15.73 ± 2.68 . μm), superior region (15.72 ± 2.70 μm), and inferior macular region (14.84 ± 2.63 μm) (P all < 0.05). And the mean thickness of the interdigitation zone band in the foveal center associated with the subfoveal choroidal thickness (P = 0.025) and level of education (P = 0.033). The increase in the thickness of the interdigitation zone band may play a role in the pathophysiologic features of various age-related ocular conditions.
