Pigment Epithelial Detachment and Leak Point Locations in Central Serous Chorioretinopathy. Am J Ophthalmol 2024; 261:19-27. [PMID: 38244961 DOI: 10.1016/j.ajo.2024.01.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Revised: 01/12/2024] [Accepted: 01/12/2024] [Indexed: 01/22/2024]
Abstract
PURPOSE To examine the associations between the vortex vein characteristics and locations of the pigment epithelial detachment (PED) and leak point in patients with central serous chorioretinopathy (CSC). DESIGN Observational case series. METHODS We evaluated 116 eyes of 104 patients with CSC. The PED and leak point locations were superimposed over the choroidal en face images using widefield swept-source optical coherence tomography and fluorescein angiography. We defined the draining areas of the superior and inferior vortex veins and analyzed their associations with the PED and leak point locations. RESULTS One of the 116 eyes with a unique irrigation pattern dominated by the nasal vortex vein was excluded from the analysis. Sixty-nine (60%) of the remaining 115 eyes exhibited asymmetry between the superior and inferior vortex veins. PEDs and leak points were in the vortex vein draining area with greater dilation in 66 (96%) of 69 eyes with asymmetry, and none (0%) were in the opposite areas. Both the PEDs and leak points showed significant differences in their distributions (P < .001, respectively). Additionally, 74% of PEDs and 84% of leak points were located upstream of the vortex vein draining areas, whose frequency was significantly higher compared to other areas (P < .001, respectively). CONCLUSION PED and leak point spatial distributions corresponded with the most terminal part of the dilated vortex veins, suggesting that blood flow disturbances, such as stasis within the affected vortex veins, may be essential in the pathogenesis of CSC.

Abstract
PURPOSE To assess relationships between demographics, clinical characteristics, and optical coherence tomography characteristics with persistence of metamorphopsia after resolution of subretinal fluid in eyes with chronic central serous chorioretinopathy. METHODS One-hundred participants with "resolved" (absence of subretinal fluid) chronic central serous chorioretinopathy were retrospectively analyzed. Patients underwent a complete ophthalmologic evaluation, including assessment of the presence of metamorphopsia. At the study visit, optical coherence tomography scans were reviewed for qualitative and quantitative features. RESULTS Sixty-six of 100 patients (66.0%) complained of metamorphopsia. Both the foveal and parafoveal ganglion cell complex thicknesses were thinner in central serous chorioretinopathy eyes with metamorphopsia (35.1 ± 10.6 µ m and 82.0 ± 18.1 µ m vs. 40.7 ± 11.8 µ m and 93.1 ± 13.5 µ m, P = 0.030 and P < 0.0001). In the foveal region, the outer plexiform layer and outer nuclear layer thicknesses were thinner in patients with metamorphopsia (24.6 ± 8.5 µ m and 63.1 ± 20.9 µ m vs. 29.1 ± 8.7 and 76.2 ± 18.2 µ m, P = 0.016 and P = 0.005). The ellipsoid zone band was more frequently discontinued in eyes with metamorphopsia (56.1% vs. 35.3%, P = 0.039). Multivariate stepwise linear regression analysis demonstrated that the strongest associations with the presence of metamorphopsia were with parafoveal ganglion cell complex thickness ( P = 0.004), foveal outer nuclear layer thickness ( P = 0.010), and number of previous recurrences of subretinal fluid accumulation ( P = 0.017). The time interval from the last subretinal fluid resolution was not associated with the presence of metamorphopsia. CONCLUSION In "resolved" central serous chorioretinopathy, clinical aspects (i.e., number of previous recurrences) and structural changes (i.e., ganglion cell complex and outer nuclear layer thinning) are associated with metamorphopsia after subretinal fluid resolution.

Abstract
Modern advances in diagnostic technologies offer the potential for unprecedented insight into ophthalmic conditions relating to the retina. We discuss the current landscape of artificial intelligence in retina with respect to screening, diagnosis, and monitoring of retinal pathologies such as diabetic retinopathy, diabetic macular edema, central serous chorioretinopathy, and age-related macular degeneration. We review the methods used in these models and evaluate their performance in both research and clinical contexts and discuss potential future directions for investigation, use of multiple imaging modalities in artificial intelligence algorithms, and challenges in the application of artificial intelligence in retinal pathologies.

Abstract
Similar to ultrasound adapting soundwaves to depict the inner structures and tissues, optical coherence tomography (OCT) utilizes low coherence light waves to assess characteristics in the eye. Compared to the previous gold standard diagnostic imaging fluorescein angiography, OCT is a noninvasive imaging modality that generates images of ocular tissues at a rapid speed. Two commonly used iterations of OCT include spectral-domain (SD) and swept-source (SS). Each comes with different wavelengths and tissue penetration capacities. OCT angiography (OCTA) is a functional extension of the OCT. It generates a large number of pixels to capture the tissue and underlying blood flow. This allows OCTA to measure ischemia and demarcation of the vasculature in a wide range of conditions. This review focused on the study of four commonly encountered diseases involving the retina including age-related macular degeneration (AMD), diabetic retinopathy (DR), central serous chorioretinopathy (CSC), and macular telangiectasia (MacTel). Modern imaging techniques including SD-OCT, TD-OCT, SS-OCT, and OCTA assist with understanding the disease pathogenesis and natural history of disease progression, in addition to routine diagnosis and management in the clinical setting. Finally, this review compares each imaging technique's limitations and potential refinements.

Abstract
Purpose To report a case of misdiagnosed choroidal hemangioma, initially treated as central serous retinopathy (CSR) complicated by choroidal neovascularization (CNV), and to improve the proper identification of this disorder. Observations Fundus images revealed a subtle, elevated choroidal lesion with an associated exudative detachment and choroidal vascular lesion on indocyanine green (ICG) angiography. Combined treatment with photodynamic therapy (PDT) and anti-VEGF therapy led to resolution of fluid and improvement in VA from 20/50 to 20/25. Conclusion It is critical to understand the clinical features of choroidal hemangiomas and their physical presentation on retinal testing to diagnose and treat them in a timely and appropriate manner.

Factors related to the location of pigment epithelial detachment in central serous chorioretinopathy. Sci Rep 2022; 12:4507.

Abstract
Pigment epithelial detachment (PED) is common in eyes with central serous chorioretinopathy (CSC), and choroidal neovascularisation (CNV), which is almost always associated with PED, is found in a higher proportion than previously expected. Using en-face optical coherence tomography, this retrospective study aimed to investigate the PED location in relation to various geometric landmarks including the foveal centre (FC), greatest choroidal thickness (GCT) point and optic disc centre. In a total of 98 eyes, the distance from the FC to PED centroid was correlated with the ratio of GCT to subfoveal choroidal thickness (r = 0.278, P = 0.006) and the distance from the FC to GCT point (r = 0.371, P < 0.001). Eyes with CNV had a shorter distance between the PED centroid and FC (700 ± 439 μm) than those without (1191 ± 964 μm, P = 0.001). Analysis of covariance showed that the distance from the FC to the PED centroid was significantly correlated with the distance from the FC to the GCT point (P = 0.009) and the PED group with and without CNV (P = 0.020). This result suggests that the development of complicated PED with CNV can be related to both choroidal vascular abnormalities and retinal pigment epithelial insufficiency.

Abstract
PURPOSE This study aims to evaluate choroidal vascular alterations in patients with central serous chorioretinopathy (CSC) using ultra-widefield (UWF) indocyanine green angiography (ICGA). METHODS This was a retrospective case-control study conducted at a single tertiary eye center. In total, 36 eyes in patients with either unilateral (24 patients) or bilateral (six patients) treatment-naïve CSC and 30 eyes in 24 age-matched controls were evaluated. The number of quadrants with vortex vein engorgement on UWF ICGA was evaluated. Dilated choroidal vessels affecting the macula were regarded as extended vortex vein engorgement. Choroidal vascular hyperpermeability (CVH) area on late-phase ICGA was quantified using stereographic projection. The parameters were compared with clinical and optical coherence tomographic findings. RESULTS Eyes with CSC had larger CVH area, thicker choroid, and more quadrants with vortex vein engorgement and extended vortex vein engorgement compared with control eyes (all P < 0.001). In patients with unilateral CSC, affected eyes had larger CVH area, thicker choroid, and more extended vortex vein engorgements compared with unaffected fellow eyes (all P < 0.001), but vortex vein engorgement did not significantly differ. CVH was significantly correlated with extended vortex vein engorgement (P < 0.001) and subfoveal choroidal thickness (P = 0.007). CONCLUSIONS The increased number and binocular symmetry of engorged vortex veins suggest an anatomical predisposition for CSC. CVH area and extended vortex vein engorgement were indicators of choroidal outflow congestion. These parameters may serve as diagnostic clues or predictors of disease development in eyes with CSC.

Abstract
Recent improvements in ophthalmic imaging have led to the identification of a thickened choroid or pachychoroid to be associated with a number of retinal diseases. The number of conditions linked to this phenotype has continued to widen with specific endophenotypes found within the pachychoroid spectrum. The spectrum includes choroidal features such as focal or diffuse choroidal thickening and thinning of the overlying inner choroid, and choroidal hyperpermeability as demonstrated by indocyanine green angiography. In addition, these diseases are associated with overlying retinal pigmentary changes and retinal pigment epithelial dysfunction and may also be associated with choroidal neovascularization. This article provides a comprehensive review of the literature looking at diseases currently described within the pachychoroid spectrum including central serous chorioretinopathy, pachychoroid pigment epitheliopathy, pachychoroid neovasculopathy, polypoidal choroidal vasculopathy/aneurysmal type 1 neovascularization, peripapillary pachychoroid disease and focal choroidal excavation. We particularly focus on clinical imaging, genetics and pathological findings in these conditions with the aim of updating evidence suggesting a common aetiology between diseases within the pachychoroid spectrum.

Abstract
Central serous chorioretinopathy (CSCR) is a macular disease characterized by serous retinal detachment commonly involving the macular region. CSCR has a wide spectrum of clinical presentations. Although a significant proportion of CSCR cases are self-limiting, patients can suffer from persistent or recurrent disease, sometimes complicated with choroidal neovascularization, resulting in permanent visual loss. Multimodal imaging, including fluorescein angiography, indocyanine green angiography, fundus autofluorescence, and optical coherence tomography, has advanced the diagnosis and classification of CSCR cases. Evolution of new imaging techniques including optical coherence tomography angiography, wide-field imaging, and en face reconstruction imaging has also contributed to better understandings of the pathophysiology of CSCR. This review article summarizes the features of multimodal imaging for CSCR and discusses the application of such features in evaluating the disease.

Abstract
Objective To describe the morphological changes on fundus autofluorescence (FAF) and spectral-domain optical coherence tomography (SD-OCT) imaging at different chronicity of central serous chorioretinopathy (CSC). Methods This cross-sectional study included patients with CSC of different chronicity. Changes in FAF scans and morphological changes on SD-OCT were evaluated and compared at different stages of CSC. Results Sixty-nine patients were enrolled in the study, with a mean age of 52.1 ± 11.8 years. A distinct hypoautofluorescence (AF) pattern was observed at the leakage point in acute CSC (100%). The leakage site was indistinguishable in 48% of the patients with late-chronic CSC. The majority of acute CSC patients showed hyper-AF in the area of serous retinal detachment (SRD), which persisted in the early-chronic stage of CSC. In late-chronic CSC, many cases of hypo-AF (22.2%) and mixed-pattern AF (14.8%) were observed. SD-OCT revealed evolving features of retinal pigment epithelium (RPE) abnormalities in a time-dependent manner: from peaked PEDs in acute CSC to low-lying PEDs in early-chronic CSC and, eventually, flat, irregular PEDs in late-chronic CSC. The average thickness of the photoreceptor layer (inner and outer segment; IS/OS) was 79 μm in the acute group and 55.2 μm in the chronic group. The photoreceptor layer (IS/OS) height was positively associated with visual acuity (p=0.002). Conclusion Different stages of CSC present different patterns on FAF and SD-OCT imaging. Chronicity of CSC can be estimated using specific features in these images. Photoreceptor layer (IS/OS) height acts as a good and objective predictor of visual outcomes in CSC patients.

Abstract
Purpose To evaluate morphological characteristics of choroidal neovascularization in chronic central serous chorioretinopathy (CSC) presenting with flat and irregular pigment epithelium detachment (FIPED) by means of innovative multimodal imaging. Methods In this observational cross-sectional study, we examined 10 consecutive patients affected by chronic CSC and FIPED using fluorescein angiography (FA), indocyanine-green angiography (ICGA) and optical coherence tomography angiography (OCTA). A qualitative analysis of the nature and characteristics of neovascular membrane was performed, combining available multimodal imaging and literature data. Results Multiple areas of retinal pigment epithelium alterations, macular hypo- and hyperpigmentation and atrophic areas were identified. Spectral domain OCT (SD-OCT) showed subretinal fluid in 80% of eyes and the ‘double layer sign’ in all patients. Late FA phases showed staining areas without leakage in all eyes; ICGA showed a hyperfluorescent plaque with surrounding hypofluorescence in 80% of patients. OCTA detected characteristic neovascular networks in the outer retina within the FIPEDs, classified as filamentous vessels with a pruned tree-like pattern in five eyes and a tangled pattern in three eyes. The choriocapillaris network showed dark areas in 80% of eyes and diffuse dark spots in all eyes. Conclusion Multimodal imaging completes clinical characterization of FIPEDs in chronic CSC. This study using OCTA technology describes the phenotype of hidden neovascular lesions in shape and morphology.

OCT Risk Factors for 3-Year Development of Macular Complications in Eyes With "Resolved" Chronic Central Serous Chorioretinopathy. Am J Ophthalmol 2021; 223:129-139. [PMID: 33342759 DOI: 10.1016/j.ajo.2020.10.011] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2020] [Revised: 10/08/2020] [Accepted: 10/12/2020] [Indexed: 12/31/2022]
Abstract
PURPOSE To assess the relationship between demographics, clinical characteristics, and structural optical coherence tomography (OCT) findings and the development of sight-threatening macular complications (choroidal neovascularization [CNV], large areas of retinal pigment epithelium [RPE] atrophy, and cystoid macular degeneration [CMD]) in a cohort of eyes with "resolved" chronic central serous chorioretinopathy (CSC) at study baseline. DESIGN Retrospective cohort study. METHODS In this study, a total of 71 eyes with "resolved" (absence of subretinal fluid) chronic CSC at baseline and 36 months of regular follow-up examinations were retrospectively enrolled. Structural OCT scans were reviewed. Baseline OCT qualitative features reflecting distress of the neuroretina, RPE, or choroid were assessed and included ellipsoid zone discontinuity, outer nuclear layer (ONL) thinning; presence of hyper-reflective intraretinal foci; dome-shaped pigment epithelium detachment (PED); hyper-reflective flat, irregular PED; hyporeflective flat, irregular PED; and inner choroidal attenuation. OCT images obtained at follow-up visits were also reviewed for development of macular complications (CNV, large areas of RPE atrophy [at least 250 μm in diameter], and CMD). Main outcome measurements included incidence of macular complications and hazard ratio (HR) for demographics, clinical characteristics, and OCT risk factors. RESULTS At month 36, 20 eyes (28.2%) developed macular complications. Nine eyes (12.7%) displayed CNV, 9 eyes (12.7%) had large areas of RPE atrophy, and 2 eyes (2.8%) developed cystoid macular degeneration. The following factors were associated with an increased risk of development of CNV: intraretinal hyper-reflective foci had an HR of 11.58 (95% confidence interval [CI]: 1.10-37.24; P = .040); inner choroidal attenuation had an HR of 9.66 (95% CI: 1.07-22.34; P = .043); and the presence of macular complications in the fellow eye had an HR of 20.17 (95% CI: 1.34-39.41; P = .030). Factors associated with the development of RPE atrophy were also identified: ONL thinning had an HR of 13.47 (95% CI: 1.10-39.86; P = .042); dome-shaped PED had an HR of 21.40 (95% CI: 1.50-41.10; P = .031); and inner choroidal attenuation had an HR of 13.20 (95% CI: 1.07-39.32; P = .044). CONCLUSIONS OCT risk factors were identified for the development of macular complications in eyes with chronic CSC. Findings may help in the identification of high-risk patients.

Abstract
Purpose To quantitatively demonstrate asymmetric choroidal outflow in pachychoroid (central serous chorioretinopathy [CSC]/pachychoroid pigment epitheliopathy [PPE]) eyes using mid-phase, ultra-widefield indocyanine green angiography (UWF ICGA) images. Methods Eyes with a clinical diagnosis of CSC/PPE were imaged with multimodal imaging including UWF ICGA (Optos California). Quadrant brightness was measured by manually segmenting based on vortex vein location, calculating the brightness “max-min” value to assess nonuniformity between quadrants, and comparing between CSC/PPE and control eyes. A multivariate linear regression was performed to determine, across individual eyes, which specific quadrants have the greatest brightness in pachychoroid eyes, after taking into account patient-eye-specific variability. Results Thirty-three eyes (18 patients) with CSC/PPE along with 16 eyes of 9 controls had a mean age of 51.94 ± 9.72 vs. 53.78 ± 17.92 years (P = 0.731), respectively. Max-min analysis showed significantly increased likelihood of nonuniform drainage between vortex veins in both CSC/PPE and control eyes. Multivariate linear regression in control eyes showed that on average, the inferotemporal quadrant was significantly brighter than the superonasal quadrant (9.72 units, P < 0.001). Among CSC/PPE eyes, adjusting for the preferential, nonuniform drainage in control eyes, the inferonasal and inferotemporal quadrants in CSC/PPE eyes remained significantly brighter than the reference quadrant by 5.36 units (P = 0.034) and 7.51 units (P = 0.008), respectively. Conclusions Asymmetric choroidal venous outflow occurs in both control and CSC/PPE eyes based on UWF ICGA quantitative brightness levels in each quadrant. Increased brightness levels along inferior quadrants in mid-phase ICGA images suggest venous outflow congestion among eyes with CSC or PPE.

Abstract
Optical coherence tomography (OCT) is a depth-resolved imaging modality, which is able to achieve micrometer-scale resolution within biological tissue noninvasively. In the past 30 years, researchers all around the world had made several essential efforts on techniques relevant to OCT. OCT has become a routine process for eye diseases with different types. In this chapter, the three important stages in the development of OCT are briefly illustrated, including the time domain OCT (TD-OCT), the frequency domain OCT (FD-OCT) and the optical coherence tomography angiography (OCTA). Each of the technique has made great progress for use on living human eye imaging in clinical applications. TD-OCT was first proposed and commercialized, which is able to achieve acceptable 2D depth-resolved cross-sectional images of human retina in vivo. FD-OCT was the upgraded OCT technique compared with TD-OCT. By capturing the coherent signal within the Fourier space, the FD-OCT could improve the image sensitivity compared with TD-OCT, and achieve dozens of kilo hertz imaging speed. OCTA is the newest developments of OCT technique, which is able to visualize the micro vasculature networks of human retina in vivo. With OCTA technique, the newest ophthalmologic OCT system is able to achieve detailed diagnosis for both micro-structure and vasculature abnormalities for clinical applications. The further development of OCT technique on imaging speed, contrast, resolution, field of view, and so on will make OCT to be a more powerful tool for clinical usages.

Abstract
BACKGROUND To determine the association between hyperreflective area identified on the reference image (en-face image) in spectral domain optical coherence tomography (SD-OCT) scan and the leak on fluorescein angiography in patients with acute treatment naive central serous chorioretinopathy (CSCR). METHODS Retrospective, observational chart review. The reference image (en-face) image on SD OCT raster scan was examined for the presence of a hyperreflective spot and an attempt was made to correlate its location on the actual leak seen on FFA using anatomical landmarks as reference. Follow up was 6 months after CSCR resolution. Appropriate statistical analysis was made. RESULTS Sixty-two patients (65 eyes; 49 males) with CSCR were identified of which 62/65 eyes (95.38%) showed the said correlation. The mean age was 31.24 years. The mean follow-up was 17.25 months. The mean BCVA at baseline was 0.28 logMAR. The mean final BCVA was 0.08. The hyperreflective spot noted on the infrared (reference) image correlated the most with the classic ink-blot leakage as well as the minimally enhancing/ill-defined leakage pattern. In 37/41 eyes, the area of hyperreflectivitiy correlated with the pigment epithelial detachment. The hyperreflective spot resolved in most patients who received photodynamic therapy but persisted in most patients who received eplerenone therapy. Persistent hyperreflectivity after subretinal fluid resolution appeared to correlate with persistent metamorphopsia and reduced contrast sensitivity in eyes with no subretinal fluid. CONCLUSION We demonstrate an interesting correlation between the area of leak and the OCT reference image (en face) used to determine the level of the scan. SYNOPSIS The study looks at the potential applicability of a correlation between leaking areas on fundus fluorescein angiography and a hyperreflective area on the infrared image in optical coherence tomography (OCT) in patients with central serous chorioretinopathy (CSCR).

Abstract
Although central serous chorioretinopathy (CSC) presumptively shares pathophysiological basis with age-related macular degeneration (AMD), the CFH risk alleles for AMD are reportedly protective against CSC development. Our finding, that the CFH risk allele for AMD is protective against choroidal thickening in a Japanese cohort, indicates that CFH affects CSC development through its choroid-thickening effects rather than its association with AMD, highlighting the need for a new AMD classification, with CSC/pachychoroid-associated choroidal neovascularization as a distinct disease. Furthermore, our genome-wide association study (GWAS) addressing choroidal thickness successfully discovered a susceptibility gene for CSC: VIPR2. Future GWASs on choroidal thickness will likely discover additional CSC susceptibility genes and provide key molecules to elucidate the pathophysiological difference between CSC and AMD. Central serous chorioretinopathy (CSC) is a common disease affecting younger people and may lead to vision loss. CSC shares phenotypic overlap with age-related macular degeneration (AMD). As recent studies have revealed a characteristic increase of choroidal thickness in CSC, we conducted a genome-wide association study on choroidal thickness in 3,418 individuals followed by TaqMan assays in 2,692 subjects, and we identified two susceptibility loci: CFH rs800292, an established AMD susceptibility polymorphism, and VIPR2 rs3793217 (P = 2.05 × 10−10 and 6.75 × 10−8, respectively). Case–control studies using patients with CSC confirmed associations between both polymorphisms and CSC (P = 5.27 × 10−5 and 5.14 × 10−5, respectively). The CFH rs800292 G allele is reportedly a risk allele for AMD, whereas the A allele conferred risk for thicker choroid and CSC development. This study not only shows that susceptibility genes for CSC could be discovered using choroidal thickness as a defining variable but also, deepens the understanding of differences between CSC and AMD pathophysiology.

Abstract
Purpose This article reports a method for en face optical coherence tomography (OCT) imaging and quantitative assessment of alterations in both thickness and reflectance of individual retinal layers at different stages of diabetic retinopathy (DR). Methods High-density OCT raster volume scans were acquired in 29 diabetic subjects divided into no DR (NDR) or non-proliferative DR (NPDR) groups and 22 control subjects (CNTL). A customized image segmentation method identified eight retinal layer interfaces and generated en face thickness maps and reflectance images for nerve fiber layer (NFL), ganglion cell and inner plexiform layers (GCLIPL), inner nuclear layer (INL), outer plexiform layer (OPL), outer nuclear layer (ONL), photoreceptor outer segment layer (OSL), and retinal pigment epithelium (RPE). Mean thickness and intensity values were calculated in nine macular subfields for each retinal layer. Results En face thickness maps and reflectance images of retinal layers in CNTL subjects corresponded to normal retinal anatomy. Total retinal thickness correlated negatively with age in nasal subfields (R ≤−0.31; P ≤ 0.03, N = 51). In NDR subjects, NFL and OPL thickness were decreased (P = 0.05), and ONL thickness was increased (P = 0.04) compared to CNTL. In NPDR subjects, GCLIPL thickness was increased in perifoveal subfields (P< 0.05) and INL intensity was higher in all macular subfields (P = 0.04) compared to CNTL. Conclusions Depth and spatially resolved retinal thickness and reflectance measurements are potential biomarkers for assessment and monitoring of DR.

Abstract
Purpose The purpose of this study was to examine the rpea1 mouse whose retina spontaneously detaches from the underlying RPE as a potential model for studying the cellular effects of serous retinal detachment (SRD). Methods Optical coherence tomography (OCT) was performed immediately prior to euthanasia; retinal tissue was subsequently prepared for Western blotting, microarray analysis, immunocytochemistry, and light and electron microscopy (LM, EM). Results By postnatal day (P) 30, OCT, LM, and EM revealed the presence of small shallow detachments that increased in number and size over time. By P60 in regions of detachment, there was a dramatic loss of PNA binding around cones in the interphotoreceptor matrix and a concomitant increase in labeling of the outer nuclear layer and rod synaptic terminals. Retinal pigment epithelium wholemounts revealed a patchy loss in immunolabeling for both ezrin and aquaporin 1. Anti-ezrin labeling was lost from small regions of the RPE apical surface underlying detachments at P30. Labeling for tight-junction proteins provided a regular array of profiles outlining the periphery of RPE cells in wild-type tissue, however, this pattern was disrupted in the mutant as early as P30. Microarray analysis revealed a broad range of changes in genes involved in metabolism, signaling, cell polarity, and tight-junction organization. Conclusions These data indicate changes in this mutant mouse that may provide clues to the underlying mechanisms of SRD in humans. Importantly, these changes include the production of multiple spontaneous detachments without the presence of a retinal tear or significant degeneration of outer segments, changes in the expression of proteins involved in adhesion and fluid transport, and a disrupted organization of RPE tight junctions that may contribute to the formation of focal detachments.

Abstract
PURPOSE To determine the prevalence and associations of central serous chorioretinopathy (CSC) in elderly Chinese. METHODS The population-based cross-sectional Beijing Eye Study 2011 included 3468 individuals (age: 64.6 ± 9.8 years; range: 50-93 years), who underwent enhanced depth imaging of spectral-domain optical coherence tomography (SD-OCT). CSC was defined as serous detachment of the retina in the macular region without signs of haemorrhages or signs of polypoidal choroidal vasculopathy, exudative age-related macular degeneration or other retinal vascular disorders, both on fundus photographs and on optical coherence tomography (OCT) images. RESULTS Central serous chorioretinopathy was diagnosed in 10 eyes (prevalence rate: 0.15 ± 0.05%; 95% confidence interval (CI):0.06%, 0.25%) of 10 subjects (prevalence rate: 0.31 ± 0.10%; 95% CI: 0.12%, 0.50%). In five subjects, CSC was located foveally, and in five subjects, CSC was located extrafoveally. All subjects affected by foveal CSC were men, and three of the five individuals with extrafoveal CSC were men. In univariate analysis, subjects with CSC were significantly younger than the remaining study participants, and foveal CSC showed a significant (p = 0.02) predilection for men. After adjusting for age and gender, individuals with foveal CSC (383 ± 112 μm versus 270 ± 47 μm; p = 0.02) and the whole group of subjects with CSC had a significantly thicker subfoveal choroid. In a parallel manner, eyes contralateral to eyes with foveal CSC showed a significantly thicker subfoveal choroid than the age-adjusted control group (413 ± 74 μm versus 270 ± 47 μm; p = 0.001). CONCLUSIONS In Chinese aged 50+ years, the prevalence of CSC was 0.14% per subject. The choroid in the CSC affected eyes and in the contralateral unaffected eyes was significantly thicker than in an age- and gender-adjusted control population-based group.

Abstract
Purpose To present a method for image segmentation and generation of enface thickness maps and reflectance images of retinal layers in healthy and diabetic retinopathy (DR) subjects. Methods High density spectral domain optical coherence tomography (SDOCT) images were acquired in 10 healthy and 4 DR subjects. Customized image analysis software identified 5 retinal cell layer interfaces and generated thickness maps and reflectance images of the total retina (TR), inner retina (IR), outer retina (OR), and the inner segment ellipsoid (ISe) band. Thickness maps in DR subjects were compared to those of healthy subjects by generating deviation maps which displayed retinal locations with thickness below, within, and above the normal 95% confidence interval. Results In healthy subjects, TR and IR thickness maps displayed the foveal depression and increased thickness in the parafoveal region. OR and ISe thickness maps showed increased thickness at the fovea, consistent with normal retinal anatomy. In DR subjects, thickening and thinning in localized regions were demonstrated on TR, IR, OR, and ISe thickness maps, corresponding to retinal edema and atrophy, respectively. TR and OR reflectance images showed reduced reflectivity in regions of increased thickness. Hard exudates appeared as hyper-reflective spots in IR reflectance images and casted shadows on the deeper OR and ISe reflectance images. The ISe reflectance image clearly showed the presence of focal laser scars. Conclusions Enface thickness mapping and reflectance imaging of retinal layers is a potentially useful method for quantifying the spatial and axial extent of pathologies due to DR.

Abstract
Purpose : To investigate the causes of hyperreflective dots (HRDs) in spectral domain optical coherence tomography (OCT) excluding diabetic macular edema (DME) and RVO (retinal vein occlusion). Patients and Methods : The medical records of 56 patients with HRDs documented by OCT were reviewed retrospectively. The patients with DME and RVO were excluded from the study in order to prevent misdiagnosing hard exudates or HRDs. The causes, unilaterality or bilaterality of HRD and demographic properties of the patients with HRD were evaluated. Results : Sixty four eyes of 56 patients having HRDs were included in this study. Of the patients with HRD, 17 (30.36%) were women and 39 (69.64%) were men. The ages of patients were between 13 to 84 years (median 60.18 years). The causes of HRD were as follows: papilledema in 4 eyes (6.25%), active neovascular age related macular degeneration (AMD) in 33 eyes (51.56%), familial dominant drusen in 2 eyes (3.13%), central serous chorioretinopathy in 19 eyes (29.69%) and commotio retina in 2 eyes (3.13%), choroidal folds in one eye (1.56%), branch retinal artery occlusion in one eye (1.56%), central retinal artery occlusion in one patient (1.56%) and Best vitelliform macular dystrophy in one eye (1.56%). The most common cause of HRD was AMD. The causes of HRDs in both eyes were AMD and papilledema. Conclusion : The most common causes of HRDs excluding DME and RVO seem as active exudative AMD. The presence of HRDs in retinal diseases might affect the decisions and the results of the treatment and the prognosis of diseases.

Abstract
PURPOSE To evaluate whether half-dose verteporfin photodynamic therapy (PDT) is better than natural history for the treatment of central serous chorioretinopathy (CSC). METHODS Retrospective review of consecutive CSC patients treated with half-dose verteporfin PDT or untreated with observation and a minimum follow-up of 36 months. The main outcome measures included mean change in visual acuity and CSC recurrence. Survival analysis was performed to compare the CSC recurrence rates between the two groups. RESULTS A total of 192 eyes of 192 patients were included; 75 eyes were treated with half-dose verteporfin PDT and 117 were untreated. The mean follow-up duration was 74.1 months. At the last follow-up, the mean logMAR visual acuity was significantly better in the half-dose verteporfin PDT group compared with the untreated control group (P=.005). The mean visual improvement of the half-dose verteporfin PDT group at the last follow-up was 1.8 lines, compared with 0.0 line in the untreated control group (P<.001). Recurrence of CSC developed in 15 eyes (20%) in the half-dose verteporfin PDT group compared with 63 eyes (53.8%) in the untreated control group (P<.001). Survival analysis demonstrated that eyes treated with half-dose verteporfin PDT were significantly less likely to develop CSC recurrence compared with untreated controls (P<.001). Regression analysis showed that half-dose verteporfin PDT was the only significant factor in reducing the risk of CSC recurrence. CONCLUSIONS Half-dose verteporfin PDT for the treatment of CSC resulted in significantly better visual acuity outcomes and lower recurrence rate in the long term compared with untreated controls.

En-face optical coherence tomography as a novel tool for exploring the ocular surface: a pilot comparative study to conventional B-scans and in vivo confocal microscopy. Ocul Surf 2014; 12:285-306.

Abstract
PURPOSE To explore the potential of spectral-domain optical coherence tomography (SD-OCT) using the en-face technology for the imaging of ocular surface diseases and to correlate the findings with in vivo confocal microscopy (IVCM) images. PATIENTS AND METHODS 113 eyes of 75 subjects with various ocular surface diseases were investigated with the RTVue(®) anterior-segment en face OCT. En face OCT images were compared to B-scan OCT and IVCM images. RESULTS Patients with corneal dystrophies, corneal deposits, keratitis, pterygium, conjunctivochalasis, or ocular surface squamous neoplasia and patients who underwent lamellar corneal surgeries were included. En-face OCT images showed ocular surface tissue changes that were not discernible using conventional B-scan OCT. Nevertheless, there was a good correlation with IVCM analysis. Compared with IVCM, the major advantages of en-face OCT included easy operation and rapid image acquisition, with minimal operator experience required. In addition, the non-contact method avoided patient discomfort and external pressure on the globe, which was especially useful in patients with corneal dystrophies, ulcers, or corneal abscesses. Although the resolution of en-face OCT was lower than that of IVCM, it allowed useful overall visualization of corneal lesions due to the larger areas analyzed. CONCLUSION En-face SD-OCT is a novel, valuable tool to assess a wide variety of ocular surface diseases. It can provide additional information and new insight into different ocular surface conditions with no corneal contact.

Abstract
PURPOSE To report nine cases of pachychoroid pigment epitheliopathy. METHODS An observational case series of nine patients who underwent comprehensive ophthalmic examination, fundus photography, fundus autofluorescence, spectral-domain optical coherence tomography, and enhanced depth imaging optical coherence tomography. RESULTS Eighteen eyes of 9 patients, aged 27 years to 89 years, were diagnosed with pachychoroid pigment epitheliopathy based on the characteristic funduscopic appearance of reduced fundus tessellation with overlying retinal pigment epithelial changes in one or both eyes, fundus autofluorescence abnormalities, and increased subfoveal choroidal thickness confirmed by enhanced depth imaging optical coherence tomography (mean, 460.2 μm). The five older patients had been previously diagnosed with age-related macular degeneration, while the four younger subjects were referred for possible inflammatory chorioretinitis, pattern dystrophy, or nonspecific drusen. No subjects had a history of or subsequently developed subretinal fluid. CONCLUSION Pachychoroid pigment epitheliopathy falls within a spectrum of diseases associated with choroidal thickening that includes central serous chorioretinopathy and polypoidal choroidal vasculopathy, and it should be suspected in eyes with a characteristic fundus appearance related to choroidal thickening and associated retinal pigment epithelial abnormalities but no history of subretinal fluid. Enhanced depth imaging optical coherence tomography confirming an abnormally thick choroid and characteristic retinal pigment epithelial changes on fundus autofluorescence support the diagnosis. Because these patients are frequently misdiagnosed, the recognition of pachychoroid pigment epitheliopathy may avoid unnecessary diagnostic testing and interventions.

En face enhanced-depth swept-source optical coherence tomography features of chronic central serous chorioretinopathy. Ophthalmology 2013; 121:719-26. [PMID: 24289918 DOI: 10.1016/j.ophtha.2013.10.014] [Citation(s) in RCA: 146] [Impact Index Per Article: 13.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2013] [Revised: 10/03/2013] [Accepted: 10/08/2013] [Indexed: 12/13/2022] Open
Abstract
OBJECTIVE To characterize en face features of the retinal pigment epithelium (RPE) and choroid in eyes with chronic central serous chorioretinopathy (CSCR) using a high-speed, enhanced-depth swept-source optical coherence tomography (SS-OCT) prototype. DESIGN Consecutive patients with chronic CSCR were prospectively examined with SS-OCT. PARTICIPANTS Fifteen eyes of 13 patients. METHODS Three-dimensional 6×6 mm macular cube raster scans were obtained with SS-OCT operating at 1050 nm wavelength and 100000 A-lines/sec with 6 μm axial resolution. Segmentation of the RPE generated a reference surface; en face SS-OCT images of the RPE and choroid were extracted at varying depths every 3.5 μm (1 pixel). Abnormal features were characterized by systematic analysis of multimodal fundus imaging, including color photographs, fundus autofluorescence, fluorescein angiography, and indocyanine-green angiography (ICGA). MAIN OUTCOME MEASURES En face SS-OCT morphology of the RPE and individual choroidal layers. RESULTS En face SS-OCT imaging at the RPE level revealed absence of signal corresponding to RPE detachment or RPE loss in 15 of 15 (100%) eyes. En face SS-OCT imaging at the choriocapillaris level showed focally enlarged vessels in 8 of 15 eyes (53%). At the level of Sattler's layer, en face SS-OCT documented focal choroidal dilation in 8 of 15 eyes (53%) and diffuse choroidal dilation in 7 of 15 eyes (47%). At the level of Haller's layer, these same features were observed in 3 of 15 eyes (20%) and 12 of 15 eyes (80%), respectively. In all affected eyes, these choroidal vascular abnormalities were seen just below areas of RPE abnormalities. In 2 eyes with secondary choroidal neovascularization (CNV), distinct en face SS-OCT features corresponded to the neovascular lesions. CONCLUSIONS High-speed, enhanced-depth SS-OCT at 1050 nm wavelength enables the visualization of pathologic features of the RPE and choroid in eyes with chronic CSCR not usually appreciated with standard spectral domain (SD) OCT. En face SS-OCT imaging seems to be a useful tool in the identification of CNV without the use of angiography. This in vivo documentation of the RPE and choroidal vasculature at variable depths may help elucidate the pathophysiology of disease and can contribute to the diagnosis and management of chronic CSCR.

Abstract
AIMS To describe retinal and choroidal changes in acute and quiescent central serous chorioretinopathy (CSC) observed with 'En face' spectral domain optical coherence tomography (SD OCT) combined with enhanced-depth imaging (EDI). METHODS A prospective and descriptive study at the Rothschild Ophthalmologic Foundation (Paris, France) between September 2011 and February 2012. Eyes with a clinical diagnosis of CSC were examined using SD OCT with EDI, fluorescein and indocyanine green angiography. 3D reconstruction of 197 transverse sections with SD OCT, spaced of 30 μ, provided a virtual macular brick through which 496 sections in the coronal plane resulted in a C-scan or En face OCT image. RESULTS 23 of 29 eyes (79%) had serous retinal detachment (all active CSC) and 22 had pigment epithelial detachment (75%). Pigment epithelial hyperplasia was visualised in nine eyes (31%). Posterior cystoid retinal degenerations were present in five eyes (17%). The mean choroidal thickness was 491.5 μ. In 11 eyes (38%), En face OCT showed multiple hyper reflective points located at the level of the choriocapillary layer and choroidal cavitations were found in two patients. CONCLUSIONS En face OCT imaging using SD OCT is an easy, reproducible, non-invasive and effective tool to understand choroidal changes in acute and quiescent CSCR. It provides complementary morphological information, describes new semiological entities and might substitute other exams in the future.

Abstract
PURPOSE Porcine retina is an excellent model for studying diverse retinal processes and diseases. The morphologies of porcine retinal ganglion cells (RGCs) have, however, not yet been described comprehensively. The aim of the present study was to créate a classification of the RGCs using the 1, 1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate (DiI) tracing method. METHODS About 170 RGCs were retrogradely labeled by injecting DiI into the optic nerve of postmortem eyes and statistically analyzed by two different clustering methods: Ward's algorithm and the K-means clustering. Major axis length of the soma, soma area size, and dendritic field area size were selected as main parameters for cluster classification. RESULTS RGC distribution in clusters was achieved according to their morphological parameters. It was feasible to combine both statistical methods, thereby obtaining a robust clustering distribution. Morphological analysis resulted in a classification of RGCs in three groups according to the soma size and dendritic field: A (large somas and large dendritic fields), B (medium to large somas and medium to large dendritic fields), C (medium to small somas and medium to small dendritic fields). Within groups, fine clustering defined several subgroups according to dendritic arborization and level of stratification. Additionally, cells stratifying in two different levels of the inner plexiform layer were observed within the clusters. CONCLUSIONS This comprehensive study of RGC morphologies in the porcine retina provides fundamental knowledge about RGC cell types and provides a basis for functional studies toward selective RGC cell degeneration in retinal disorders.

Abstract
To determine changes in choroidal thickness in patients with central serous chorioretinopathy (CSCR) during the first 3 months after initial diagnosis and assess variable therapeutic interventions via enhanced depth imaging spectral-domain optical coherence tomography (EDI-OCT). In this prospective study, choroidal thickness was measured via EDI-OCT both in the affected and fellow eyes of 10 patients with CSCR at the fovea, as well as at 500 and 1,000 μm both temporal and nasal from the centre of the fovea and at the leakage point (if present), visualised via fluorescein angiography. Follow-up measurements were performed after 2-3 weeks, 6-8 weeks and 3 months. Seven of the 10 patients received additional systemic therapy with oral acetazolamide. A control group of eight healthy subjects was recruited to determine normal choroidal thickness in healthy eyes. The mean age of the 10 patients (9 male, 1 female) in the CSCR group was 42.1 (±9.3) years. The choroid in the affected eyes was significantly thickened at baseline compared to fellow eyes and the eyes of healthy subjects. The choroid in the fellow eyes also revealed a slight thickening at baseline compared to normal eyes. During the 3 month follow-up period, the choroidal thickness of the affected eyes showed a highly significant decrease, but did not reach normal levels. Minor changes could also be observed in the fellow eyes but did not reach statistical significance. In patients with CSCR, the average choroidal thickness not only demonstrated a significant thickening at baseline, but also showed a marked decrease after 3 months, yet not reaching normal levels. Our data indicate that after 3 months, normalisation of choroidal thickness is not yet completed.

Abstract
AIM To quantitatively evaluate the time course of macular choroidal blood flow velocity in acute central serous chorioretinopathy (CSC). METHODS This retrospective observational case series included 21 eyes of 20 patients (17 men, 3 women; mean age, 53.0 years) with treatment-naïve acute CSC. Laser speckle flowgraphy was performed to calculate macular mean blur rate (MBR), an indicator of relative blood flow velocity at the first visit, 3 and 6 months thereafter. Changes in average MBR values were compared with visual improvement at 6 months. RESULTS Subretinal fluid completely resolved in all eyes within 6 months, while best-corrected visual acuity (BCVA) significantly improved at 6 months compared to the initial BCVA. During the follow-up period, the average MBR significantly decreased to 92.8% and 82.3% at 3 and 6 months, respectively, against baseline (100%). Importantly, there was a negative correlation between the BCVA recovery and the MBR decrease, showing the possible association of MBR increase with poor visual prognosis. Multiple regression analysis demonstrated no significant correlation between MBR and ocular perfusion pressure. CONCLUSIONS These results indicate that macular choroidal blood flow velocity decreases concurrently with regression of CSC, suggesting a validity of choroidal blood flow elevation in the pathogenesis of acute CSC.

Abstract
BACKGROUND The aim was to describe the morphological alterations of the retina seen in spectral domain optical coherence tomography (SD-OCT) of eyes with central serous chorioretinopathy (CSC). PATIENTS AND METHODS Data of patients in the database with CSC examined with SD-OCT scans (n = 50) and fluorescein angiography (FA) were analyzed for representative cases exhibiting significant changes of the retinal structure allowing a direct comparison of SD-OCT with FA images and a description of the findings. RESULTS Apart from the 3 well-known CCS types [type I shows only subretinal fluid (SRF), type II only serous pigment epithelial detachment (PED) and the intermediate type showing both SRF and PED] hybrid forms were also observed in multifocal CSC, for example type I and type II next to each other. Of the patients 1 showed transformation from type II to type I over a period of 3 months. Small bulges of the retinal pigment epithelium (RPE) seen in OCT images could be angiographically related to leakage spots. Degenerative changes with subretinal granular sediments, patchy defects in the photoreceptor layer, granular alterations of the RPE and atrophy of the RPE and neuroretina were particularly observed in chronic CSC. CONCLUSION Spectral domain OCT is a valuable imaging technology enabling detailed visualization of retinal changes in patients with CSC. It gives access to a better understanding of the disease mechanisms and may provide a new approach to the classification and understanding of CSC.

Abstract
Central serous chorioretinopathy (CSCR) is a common retinal cause of vision loss. This review surveys the epidemiology, risk factors, clinical presentation, natural history and pathophysiology of CSCR. Studies suggest an annual incidence rate of 10 per 100 000 in men, with CSCR occurring six times more commonly in men compared with women. Most acute CSCR cases resolve spontaneously within 2-3 months. Prognosis is highly dependent on presenting visual acuity; patients with initial visual acuities of 6/6 remain at that level, while patients with initial visual acuities of less than 6/9 recover on average two to three Snellen lines over the next few years. The main risk factors for CSCR are systemic corticosteroid use, type A personality, pregnancy and endogenous Cushing's syndrome. The pathophysiology of CSCR remains obscure, although disorders in both the choroidal circulation and retinal pigment epithelium are implicated.

Abstract
BACKGROUND Central serous chorioretinopathy (CSC) is a condition that originates from alterations of the choroidal circulation. The aim of this paper was to evaluate the use of indocyanine green angiography (ICGA) in patients with chronic CSC. MATERIAL/METHODS The analysis included 17 patients (34 eyes) with chronic CSC in at least 1 eye. The eye examination included: distance and near visual acuity, biomicroscopy, applanation tonometry, fundus examination, colored and red-free fundus photography, evaluation of autofluorescence, optical coherence tomography, and fluorescein and indocyanine green angiography. RESULTS In 34 eyes (100%) involved in the ICGA study the results revealed zones of transient increased choroidal vessels permeability. In 18 eyes (52.9%) choroidal changes were accompanied by a focal serous pigment epithelial detachment. In 4 eyes (11.8%) of 3 patients' the ICGA examination confirmed the presence of occult choroidal neovascularization (CNV). In the patient with bilateral diffuse retinal pigment epitheliopathy, CNV was present in 1 eye, in the patient with unilateral chronic CSC it was also present in 1 eye, and in the third patient with bilateral chronic CSC it was detected in both eyes. CONCLUSIONS ICGA is a very useful examination that enables ophthalmologists to visualize choroidal changes due to chronic CSC, as well as to diagnose occult CNV in chronic CSC.

Abstract
PURPOSE To assess retinal blood flow in patients with central serous chorioretinopathy (CSR). METHODS The hospital-based observational comparative study included a study group with 12 patients (age: 45 ± 13 years) with an acute onset of CSR and a control group of 12 subjects matched for age and gender with the study group. The diagnosis was substantiated by fluorescein angiography and optical coherence tomography. All study participants underwent measurement of retinal blood perfusion using the retinal function imager (RFI). RESULTS The retinal blood flow velocity in the retinal veins was significantly lower in the study group than in the control group (2.76 ± 0.53 mm/s versus 3.33 ± 0.76 mm/s; p = 0.03).The difference between the study group and control group was more marked for the larger retinal veins (2.87 ± 0.51 mm/s versus 3.47 ± 0.48 mm/s; p = 0.001) than for the smaller veins (2.69 ± 0.53 mm/s versus 3.42 ± 1.05 mm/s; p = 0.04). Both groups did not differ significantly in the data of the retinal arterial flow velocities. CONCLUSIONS The data suggest an abnormal retinal venous blood flow regulation in patients with active CSR.

Abstract
PURPOSE OF REVIEW Greater understanding of central serous chorioretinopathy (CSCR) has changed initial beliefs that CSCR is a benign condition affecting young men with almost complete resolution. CSCR has a spectrum of presentations with more diffuse retinal dysfunction and variations between races. CSCR can affect older individuals and in a subset of patients may lead to significant ocular morbidity. RECENT FINDINGS Advances in imaging, particularly in indocyanine green angiography and optical coherence tomography, have led to a greater understanding of the pathophysiology of this condition. Treatments for CSCR are still evolving, in particular photodynamic dynamic therapy using lower doses and reduced fluence showing promising results. More research is required on ideal dosage. Anti-vascular endothelial growth factor treatment offers a new medical treatment modality with promising results. SUMMARY There have been recent imaging developments in addition to therapeutic advances for refractory CSCR.

Abstract
PURPOSE To assess morphologic differences in pigment epithelial detachment (PED) with en face optical coherence tomography in central serous chorioretinopathy (CSC) and age-related macular degeneration (AMD). METHODS We recruited 30 eyes of 22 patients with PED. Nine eyes had a clinical diagnosis of CSC and 21 had AMD. All patients were assessed with en face optical coherence tomography. Morphologic PED aspects were estimated on C-scans and classified according to shape, inner silhouette, content, wall aspects, wall thickness, and size. RESULTS Pigment epithelial detachment shape was predominantly circular (88.8%) in CSC and irregular or with multilobular features in AMD (76.2%). The PED inner silhouette had a smooth aspect (88.9%) in CSC and a slightly granular aspect or granular profile in AMD (100%). Clear PED content was the most characteristic feature of CSC (88.9%) but not of AMD. In CSC, PED morphologic wall aspect was uniform or slightly irregular (100%), while in AMD, it was slightly irregular (52.4%) or irregular (47.6%). Pigment epithelial detachment wall thickness and dimensions were larger in AMD than in CSC. Statistically significant differences were observed between CSC and AMD concerning PED inner silhouette, contents, wall aspects, and wall thickness measurements. CONCLUSION En face optical coherence tomography scanning is a valuable tool for showing important morphologic differences between CSC and AMD.

Abstract
In the acute stage central serous chorioretinopathy (CSC) is characterized by serous retinal detachment. Monofocal or multifocal structural changes of the pigment epithelium layer are common. Unilateral blurred vision is the major clinical symptom. The pathogenesis is unclear but corticosteroids and stress may trigger the disease. Normal vision often returns spontaneously within a few months. Therapeutic options are at a low evidence level. Carbonic anhydrase, mild laser photocoagulation, selective retinal therapy, photodynamic therapy and the intravitreal injection of bevacizumab have been reported. The authors suggest a treatment strategy on the basis of the available data.

Abstract
PURPOSE Optical coherence tomography (OCT) is restricted by its low scanning speed and limited resolution. High-definition raster-scanning OCT (HD-OCT) was used to evaluate changes in retinal microstructure in patients with acute central serous chorioretinopathy (CSCR) and to find new morphological features. METHODS Eighteen patients with subretinal fluid accumulation caused by acute CSCR were imaged in a cross-sectional study design. High-speed frequency-domain HD-OCT was used to image an area of 6 x 6 mm in the macular retina. Three-dimensional analyses were performed using en-face imaging and section analysis of single HD-OCT scans. RESULTS Detailed information about fluid accumulation can be obtained in all compartments. Discrete changes in reflectivity are visualized within the outer nuclear or plexiform layers in > 90% of patients. Subretinal fluid appears as a dome-shaped pool of fluid and is not associated with a loss of photoreceptor layer integrity. Deposits are demarcated beneath the outer cone segments. Multiple small pigment epithelial detachments are present in > 60% of patients. CONCLUSIONS High-definition OCT provides extensive information regarding precise topographic and layer-specific localization of discrete morphological changes. Along with well-known changes in the retinal microstructure, hyper-reflectivity can be imaged in the outer nuclear or plexiform layers and may represent intraretinal changes indicating the presence of subretinal pathologies or retinal maladjustment caused by the underlying pathology.

Abstract
BACKGROUND Conventional optical coherence tomography (OCT) has brought new insights to retinal diagnostics, but it is restricted due to its low scanning speed and limited resolution. In this study, high-resolution raster scanning OCT (HR-OCT) was used to identify typical changes in central serous chorioretinopathy (CSC). METHODS Fifteen consecutive patients with acute CSC were imaged using HR-OCT with an axial image resolution of 6 mum. The scanned area measured 6x6 mm2. Three-dimensional (3D) evaluation was performed using various analysing programmes. RESULTS Topographic changes in CSC could be visualised with 3D reconstructions in all locations. Retinal thickness was measured with the automatic segmentation mode and quantified precisely. Results were presented in 2D and 3D maps. En-face imaging as a modality to present an integrative overview showed specific alterations in CSC. CONCLUSION HR-OCT was able to provide essential additional information about CSC when combined with appropriate analysing programmes, allowing the identification of typical differences. Aside from precise volumetric measurements, exact localisation of pathological deviations could be achieved.

Abstract
PURPOSE To examine changes in the outer layer of the detached retina in rhegmatogenous retinal detachment (RRD) and central serous chorioretinopathy (CSC) with optical coherence tomography (OCT). DESIGN Retrospective, observational case series. METHODS Fifteen eyes (15 patients) with RRD and 16 eyes (16 patients) with acute CSC were studied by OCT-ophthalmoscope. All patients had a macular detachment within 1 month after subjective onset. We measured the height of the foveal RD and the thicknesses of the outer nuclear layer (ONL) and the detached neurosensory retina; the thickness of the latter two were measured at the thickest points within 2 degrees of the center of the fovea using vertical and horizontal scans at the initial OCT examination. RESULTS The mean best-corrected visual acuity (BCVA) after reattachment improved in both groups. The ONL was significantly thicker in the RRD group than in the CSC group (133.7 +/- 62 microm, 67.0 +/- 12.0 microm; P < .001). There was no significant difference in the thickness of the detached sensory retina between the groups (P = .06). In the RRD group, the BCVA after reattachment was correlated with the thickness of the ONL and the height of the detachment (R = 0.55, P = .03; R = 0.75, P = .004). There were no correlations between the retinal morphologic changes and the BCVA in the CSC group. CONCLUSION The ONL became thicker in patients with a RRD, and the structure of the detached sensory retina was preserved in patients with CSC. The difference in the morphologic changes in the ONL in RD might be associated with visual function.
