Abstract
PURPOSE We describe the association between active ocular toxoplasmosis and Multiple Evanescent White Dot Syndrome (MEWDS). PATIENTS AND METHODS Retrospective observational case report of a patient who presented with concomitant ocular toxoplasmosis and MEWDS (Erasmus University Hospital, Brussels, Belgium). Clinical record and multimodal imaging including fundus autofluorescence (FAF), fluorescein angiography (FA), indocyanine green angiography (ICGA), and spectral domain optical coherence tomography (SD-OCT) were analyzed. RESULTS Multimodal imaging of a 25-year-old-woman that presented with concomitant active ocular toxoplasmosis and MEWDS is described. Both clinical entities regressed completely after 8 weeks under steroidal anti-inflammatory drugs and antibiotics. CONCLUSION Active ocular toxoplasmosis can be associated with simultaneous multiple evanescent white dot syndrome. Further reports are needed to precise and characterize this clinical relationship and its management.Abbreviations: MEWDS: Multiple Evanescent White Dot Syndrome; Fundus Autofluorescence FAF; BCVA: Best-corrected Visual Acuity; FA: Fluorescein Angiography; ICGA: Indocyanine Green Angiography; SD-OCT: Spectral Domain Optical Coherence Tomography; IR: Infrared.

Abstract
Background The fast development of swept-source optical coherence tomography (SS-OCT) and swept-source optical coherence tomography angiography (SS-OCTA) enables both anterior and posterior imaging of the eye. These techniques have evolved from a research tool to an essential clinical imaging modality. Main text The longer wavelength and faster speed of SS-OCT and SS-OCTA facilitate better visualization of structure and vasculature below pigmented tissue with a larger field of view of the posterior segment and 360-degree visualization of the anterior segment. In the past 10 years, algorithms dealing with OCT and OCTA data also vastly improved the image quality and enabled the automated quantification of OCT- and OCTA-derived metrics. This technology has enriched our current understanding of healthy and diseased eyes. Even though the high cost of the systems currently limited the widespread use of SS-OCT and SS-OCTA at the first beginning, the gap between research and clinic practice got obviously shortened in the past few years. Conclusions SS-OCT and SS-OCTA will continue to evolve rapidly, contributing to a paradigm shift toward more widespread adoption of new imaging technology in clinical practice.

Diagnosis, Mechanisms, and Differentiation of Inflammatory Diseases of the Outer Retina: Photoreceptoritis versus Choriocapillaritis; A Multimodal Imaging Perspective. Diagnostics (Basel) 2022; 12:diagnostics12092179. [PMID: 36140579 PMCID: PMC9497689 DOI: 10.3390/diagnostics12092179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 09/06/2022] [Accepted: 09/07/2022] [Indexed: 11/17/2022] Open
Abstract
Background and aim: Inflammatory diseases that affect the outer retina do so by different mechanisms. Some of them result from the direct, primary involvement of the outer retina (primary photoreceptoritis) such as acute zonal outer occult retinopathy (AZOOR). Others affect the photoreceptors secondarily due to the inflammatory involvement of the choriocapillaris. This results in choriocapillaris non-perfusion that damages the photoreceptors due to the ensuing ischaemia, a mechanism characterising primary inflammatory choriocapillaropathies (PICCPs) such as multiple evanescent white dot syndrome (MEWDS), idiopathic multifocal choroiditis (MFC), and others. Thanks to multimodal imaging (MMI), it is now possible to differentiate between these two mechanisms of outer retinal damage. The aim of this study is to determine the MMI characteristics that allow us to differentiate primary photoreceptoritis, including AZOOR, from PICCPs such as MEWDS and MFC. Methods: A series of eight PICCPs cases (five typical MEWDS and three typical active MFC cases) and four typical primary photoreceptoritis/AZOOR cases (five eyes) that had undergone complete MMI investigation, including fundus photography (FP), blue light fundus autofluorescence (BL-FAF), spectral domain optical coherence tomography (SD-OCT), OCT angiography (OCT-A, when available), fluorescein angiography (FA), and indocyanine green angiography (ICGA) were analysed, pointing out the differences that allow us to distinguish primary photoreceptoritis from PICCPs. Results: All primary photoreceptoritis/AZOOR cases showed (1) faint fundus pallor around the fovea, (2) BL-FAF hyperautofluorescence, (3) loss of photoreceptor outer segments (PROS) on SD-OCT, (4) absence of choriocapillary drop-out on OCT-A, (5) normal FA or faint FA hyperfluorescence, and (6) conserved ICGA fluorescence/no hypofluorescent areas; (1), (2), (3), and (5) indicated loss of photoreceptor outer segments, and (4) and (6) indicated conserved choriocapillaris circulation. For PICCPs, (a) fundus showed discreet white dots or none (in MEWDS) and punched-out scars in MFC, (b) BL-FAF hyperautofluorescence, (c) loss of PROS on SD-OCT, (d) FA faint hyperfluorescence in MEWDS, also minimal in active MFC lesions (e) in all cases ICGA hypofluorescent areas; (b) and (c) indicating loss of PROS, and (e) indicating choriocapillaris non-perfusion in all cases. The OCT-A did not show consistent findings with faint or no capillary drop-out in MEWDS and MFC. Conclusions: MMI combining the SD-OCT and BL-FAF clearly showed loss of PROS in both groups, while the ICGA determined whether this was due to choriocapillaris non-perfusion in PICCPs or whether the choriocapillaris was intact in case of primary photoreceptoritis. The FA and OCT-A were found to be less useful and/or less sensitive for the appraisal of both these entities.

Abstract
PURPOSE Over the past two decades, advancements in imaging modalities have significantly evolved the diagnosis and management of retinal diseases. Through these novel platforms, we have developed a deeper understanding of the anatomy of the choroidal vasculature and the choriocapillaris. The recently developed tools such as optical coherence tomography (OCT) and OCT angiography (OCTA) have helped elucidate the pathological mechanisms of several posterior segment diseases. In this review, we have explained the anatomy of the choriocapillaris and its close relationship to the outer retina and retinal pigment epithelium. METHODS A comprehensive search of medical literature was performed through the Medline/PubMed database using search terms: choriocapillaris, choroid, quantification, biomarkers, diabetic retinopathy, age-related macular degeneration, choroidal blood flow, mean blur rate, flow deficit, optical coherence tomography, optical coherence tomography angiography, fluorescein angiography, indocyanine green angiography, OCTA, Doppler imaging, uveitis, choroiditis, white dot syndrome, tubercular serpiginous-like choroiditis, choroidal granuloma, pachychoroid, toxoplasmosis, central serous chorioretinopathy, multifocal choroiditis, choroidal neovascularization, choroidal thickness, choroidal vascularity index, choroidal vascular density, and choroidal blood supply. The search terms were used either independently or combined with choriocapillaris/choroid. RESULTS The imaging techniques which are used to qualitatively and quantitatively analyze choriocapillaris are described. The pathological alterations in the choriocapillaris in an array of conditions such as diabetes mellitus, age-related macular degeneration, pachychoroid spectrum of diseases, and inflammatory disorders have been comprehensively reviewed. The future directions in the study of choriocapillaris have also been discussed. CONCLUSION The development of imaging tools such as OCT and OCTA has dramatically improved the assessment of choriocapillaris in health and disease. The choriocapillaris can be delineated from the stromal choroid using the OCT and quantified by manual or automated methods. However, these techniques have inherent limitations due to the lack of an anatomical distinction between the choriocapillaris and the stromal choroid, which can be overcome with the use of predefined segmentation slabs on OCT and OCTA. These segmentation slabs help in standardizing the choriocapillaris imaging and obtain repeatable measurements in various conditions such as diabetic retinopathy, age-related macular degeneration, pachychoroid spectrum, and ocular inflammations. Additionally, Doppler imaging has also been effectively used to evaluate the choroidal blood flow and quantifying the choriocapillaris and establishing its role in the pathogenesis of various retinochoroidal diseases. As tremendous technological advancements such as wide-field and ultra-wide field imaging take place, there will be a significant improvement in the ease and accuracy of quantifying the choriocapillaris.

Abstract
INTRODUCTION White dot syndromes are a heterogeneous group of diseases that affect different layers in the retina and choroid. Multimodal imaging is fundamental in the diagnosis, but also can be crucial in unveiling the pathogenesis of these entities. MATERIAL AND METHODS Literature review. RESULTS Optical coherence tomography (OCT) provides depth-resolved, histological grade images of the vitreous, retina, and choroid. This technology is very useful to localize the primary nature and level of pathology of the various white dot syndromes. En face OCT can provide additional information regarding the interrelationship of lesion types. Vascular involvement at the level of the retina, choriocapillaris or choroid can be assessed by en face OCT angiography (OCT-A) and is not limited by masking, leakage or staining as can occur with conventional angiography (fluorescein or indocyanine green angiography) which requires dye injection. CONCLUSION OCT and OCTA are fundamental in the diagnosis and follow-up of white dots syndromes.

Abstract
An important goal of advancements in ocular imaging algorithms and devices has been to improve the image acquisition and resolution of deeper ocular tissues, namely the choroid and its vasculature that are otherwise inaccessible to direct clinical examination. These advancements have contributed to the understanding of the pathophysiology of a number of ocular inflammatory conditions. We focuse on the imaging characteristics of clinical conditions where imaging the choroid has improved or radically changed the understanding of the disease, has helped in differentiation of phenotypically similar but distinct lesions, and where imaging features have proven vital formonitoring disease activity. The last two decades have seen some major developments in ocular imaging relevant to uveitis. The current review addresses both the imaging characteristics and their interpretation on conventional modalities such as fundus photography, fluorescein angiography, indocyanine green angiography and fundus autofluorescence and the recent additions in the armamentarium including optical coherence tomography (OCT) with enhanced depth imaging, swept-source OCT, and OCT angiography.

Multiple evanescent white dot syndrome (MEWDS): update on practical appraisal, diagnosis and clinicopathology; a review and an alternative comprehensive perspective. J Ophthalmic Inflamm Infect 2021; 11:45.

Abstract
BACKGROUND Multiple evanescent white dot syndrome (MEWDS) is a rare inflammatory eye condition affecting the outer retina as a consequence of choriocapillaris non perfusion. The pathophysiology of MEWDS will be discussed based clinical appraisal and on multimodal imaging appraisal. METHODS Narrative review and perspective opinion. RESULTS Literature review results helped us to put forward (1) the specific symptomatology (decreased/blurred vision, photopsia, subjective scotomas), (2) the ill-asserted character of clinical findings (foveal granularity, white dots in fundoscopy), (3) and the crucial importance of multimodal imaging with the diagnostic triad of ICGA hypofluorescent areas, BL-FAF hyperautofluorescent areas and loss/damage of IS/OS-ellipsoid zone on SD-OCT that characterise the disease and can practically help the clinician to diagnose MEWDS. A comprehensive alternative perspective of the disease was formulated. CONCLUSIONS The bulk of evidence that we are presenting in this review, thanks to new performing non-invasive and invasive imaging modalities, is sufficiently compelling to consider MEWDS as a primary choriocapillaritis/inflammatory choriocapillaropathy. Multimodal imaging allows the clinician to diagnose MEWDS with a high level of certainty and ensures a precise follow-up.

Abstract
The choriocapillaris is the innermost structure of the choroid that directly nourishes the retinal pigment epithelium and photoreceptors. This article provides an overview of its hemovasculogenesis development to achieve its final architecture as a lobular vasculature, and also summarizes the current histological and molecular knowledge about choriocapillaris and its dysfunction. After describing the existing state-of-the-art tools to image the choriocapillaris, we report the findings in the choriocapillaris encountered in the most frequent retinochoroidal diseases including vascular diseases, inflammatory diseases, myopia, pachychoroid disease spectrum disorders, and glaucoma. The final section focuses on the development of imaging technology to optimize visualization of the choriocapillaris as well as current treatments of retinochoroidal disorders that specifically target the choriocapillaris. We conclude the article with pertinent unanswered questions and future directions in research for the choriocapillaris.

Abstract
PURPOSE This work reports a case of long-standing punctate inner choroidopathy (PIC) presenting with acute-onset multiple evanescent white dot syndrome. METHODS A 44 year-old man presented with new onset of flashes and a peripheral spot of blurry vision in the right eye. His ocular history included PIC in both eyes. RESULTS Corrected visual acuities and intraocular pressures were normal. Posterior segment examination of the right eye demonstrated old PIC lesions and new, deep-yellow lesions in the posterior pole and midperiphery. Four months later, these lesions had resolved. CONCLUSIONS Coexistence of PIC and multiple evanescent white dot syndrome has been rarely reported, and more research is warranted to investigate a possible shared etiology.

Abstract
PURPOSE To describe the application of OCT-A in various posterior uveitis disorders in our experience and to compare it with the available literature. METHODS Eighteen eyes with the diagnoses of multifocal choroiditis (MFC), multifocal placoid pigment epitheliopathy (APMPPE), multiple evanescent white dot syndrome (MEWDS), tuberculous serpiginous-like choroiditis (SLC), serpiginous choroiditis (SC), and birdshot chorioretinopathy (BSCR) were studied. RESULTS We found flow void of the choriocapillaris in patients with APMPPE, SC, MFC, BSCR, and in SLC. In contrast, perfusion of the choriocapillaris seemed normal in patients with MEWDS. CONCLUSIONS We confirmed that OCT-A contributes new information on the physiopathology of white dot syndromes and inflammatory chorioretinopathies, notably on whether or not the choriocapillaris is involved. Comparing the OCT-A features allowed us to suggest that both APMPPE and SLC might be part of the same spectrum of inflammatory disease with primary involvement at the level of the choriocapillaris and secondary RPE damage.

Abstract
PURPOSE To evaluate multifocal evanescent white dot syndrome (MEWDS) patients with and without overlapping multifocal choroiditis (MFC). METHODS Thirty-four patients diagnosed between November 2008 and August 2018 at 2 hospitals were retrospectively reviewed. Multimodal imaging including optical coherence tomography angiography (OCTA) was assessed. RESULTS Twenty-seven (79%) patients were women (overall mean age, 30 years). Five developed MFC lesions in the affected eyes, and one developed MFC in the unaffected fellow eye. Another developed combined MEWDS and MFC in the fellow eye during follow-up. Eyes with MFC had thicker choroids (316.5 and 197.3 µm, respectively; P = .001) at presentation, which became thinner after resolution (P = .043). Those with subfoveal MFC had poor visual prognosis (P = .019). Areas of suspected choriocapillaris flow deficit were identified on OCTA. CONCLUSION Some MEWDS patients may develop overlapping MFC in the same or fellow eyes, presenting with increased choroidal thickness which decreased after resolution.

Abstract
Introduction: Swept-source optical coherence tomography (SS-OCT) imaging has ushered in an era of rapid and high-resolution imaging of the retinochoroid that provides detailed patho-anatomy of various layers.Areas covered: In this detailed review, the technology of swept-source imaging including its principles and working has been discussed. The applications of SS-OCT in various conditions including age-related macular degeneration, diabetic retinopathy, pachychoroid spectrum of diseases, and inflammatory vitreoretinal conditions have been elaborated. For each disease, a brief review of literature along with the utility of SS-OCT and optical coherence tomography angiography has been provided with supporting figures. The advantages of SS-OCT over spectral-domain have been discussed if there is sufficient evidence in the literature. Finally, the review summarizes the technological advantages in this field of retinal imaging.Expert opinion: The introduction of SS-OCT in our clinics has added newer devices in our armamentarium that can provide high-quality images of the deep retina and choroid. These advances in medical devices can help in improving our knowledge relating to the pathophysiology of diseases and their evolution. In the near future, rapid and high-resolution imaging may provide real-time volumetric information of the whole retina and the choroid that can be readily used for patient care.

Graefes Arch Clin Exp Ophthalmol 2020; 258:751-758. [PMID: 31907643 DOI: 10.1007/s00417-019-04571-0] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2019] [Revised: 11/28/2019] [Accepted: 12/13/2019] [Indexed: 11/28/2022] Open
Abstract
PURPOSE To compare the characteristics of choroidal transmission in punctate inner choroidopathy (PIC) with or without choroidal neovascularization (CNV) and myopic CNV (mCNV) using spectral domain optical coherence tomography (SD-OCT). METHODS This retrospective observational case series includes 22 consecutive myopic patients (22 eyes) recruited from April 2016 until April 2018 who complained of acute blurring of vision and showed evidence of hyper-reflective material on SD-OCT imaging. Each patient underwent a comprehensive eye examination and imaging with fundus fluorescein angiography (FFA), SD-OCT, and SD-OCT angiography (SD-OCTA). Based on the results of SD-OCTA imaging and the color fundus imaging, the patients were divided into 2 groups: a group with myopic choroidal neovascularization (mCNV group, n = 10 eyes) and a group with PIC and no evidence of CNV at baseline (PIC group, n = 12 eyes). Four eyes diagnosed with PIC developed secondary PIC-CNV during follow-up. The characteristics of choroidal transmission in these eyes using SD-OCT imaging were compared. RESULTS At baseline, none of the PIC lesions showed any evidence of blood flow within the lesions on OCTA imaging. However, all of the eyes with mCNV showed flow signals within the subretinal neovascularization on SD-OCTA and subretinal or intra-retinal fluid on SD-OCT imaging. These eyes with mCNV showed subretinal hyper-reflectivity associated with choroidal hypo-transmission accompanied by retinal pigment epithelium (RPE) and ellipsoid zone (EZ) disruption. In eyes with PIC inflammatory lesions, disruption of both the RPE and EZ were observed in 33% of the inflammatory lesions, and disruption of the EZ alone was observed in 67% of the lesions at the baseline. They all showed a hyper-reflective subretinal lesion located above RPE. Three cases (25%) showed evidence of choroidal hyper-transmission at the baseline, while the remaining had normal transmission within the first month after onset. Hyper-transmission then developed in all the lesions as the disease progressed. Four cases of PIC (33%) developed PIC-related CNV that showed choroidal hypo-transmission along with hyper-transmission with disruption of the RPE and EZ. In cases with PIC-related CNV, evidences of neovascularization on SD-OCTA imaging were all detected afterwards. No intra-retinal fluid was detected before secondary CNV occurred. CONCLUSION SD-OCT imaging can noninvasively differentiate and track the progression of inflammatory lesions and myopic CNV by using the presence of choroidal hyper-transmission as a sign of just an inflammatory lesion and the presence hypo-transmission as a sign of a secondary CNV, which provides a convenient strategy for diagnosis and treatment of these lesions.

Abstract
Before the introduction of optical coherence tomography angiography (OCTA) in the early 2000s, dye-based angiography was considered the “gold standard” for the diagnosis and monitoring of ocular inflammation. OCTA is a novel technique, which demonstrates capillary networks based on the amount of light returned from moving blood cells, providing further information on pathophysiological changes in uveitis. The aim of this review is to describe the basic principles of OCTA and its application to ocular inflammatory disorders. It particularly emphasizes on its contribution not only in the diagnosis and management of the disease but also in the identification of possible complications, comparing it with fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA). Although the advent of OCTA has remarkably enhanced the assessment of uveitic entities, we highlight the need for further investigation in order to better understand its application to these conditions.

Involvement of Inner Choroidal Layer in Choroidal Thinning during Regression of Multiple Evanescent White Dot Syndrome. J Ophthalmol 2019; 2019:6816925.

Abstract
Purpose To investigate relationships between total thickness and the thickness of inner and outer layers in the choroid during regression in patients with multiple evanescent white dot syndrome (MEWDS). Methods This retrospective observational case series included 15 unilaterally affected eyes and 13 unaffected fellow eyes from 15 MEWDS patients (4 men and 11 women; mean age, 37.6 ± 17.6 years). Using enhanced depth imaging optical coherence tomography, whole, inner, and outer choroidal layer thicknesses at the fovea and perifovea were manually measured at the initial visit and at 1 and 3 months after the initial visit. The mean thickness values of the layers were compared at each stage. Results With regression of MEWDS, the mean subfoveal whole and inner choroidal layer thicknesses significantly decreased at 1 and 3 months compared to baseline values in MEWDS eyes (P=0.01 and P < 0.0001, respectively), but not in fellow eyes. The outer layer in MEWDS eyes tended to thin. Changes in the inner and outer layers at the perifovea in MEWDS eyes also showed the same trends. Simple linear regression analysis revealed significant positive correlations in choroidal thickness changes between the whole and inner layers (R = 0.53, P=0.04) and between the whole and outer layers (R = 0.91, P < 0.0001) from baseline to 3 months. Multiple linear regression analysis revealed that choroidal thickness changes in the whole layer were significantly correlated with those in the inner (β = 0.51, P < 0.0001) and outer (β = 0.73, P < 0.0001) layers. Conclusion The inner choroidal layer significantly thinned with regression of MEWDS, correlating with the thinning of total choroidal thickness. These results suggest that MEWDS lesions in the choroid are likely to lie mainly in the inner layer.

Abstract
Background The broad spectrum of uveitis disorders requires a multimodal imaging approach in the daily practice of an ophthalmologist. As inflammatory conditions, they have in common an alteration in leukocyte migration. In this context, optical coherence tomography angiography (OCTA) might be of great value for diagnosing or following up patients with these disorders. To date, OCTA has rather been used as an additional tool besides the well-established diagnostic imaging tools, but its complementary diagnostic features become increasingly relevant, to follow disease activity and treatment response and for the understanding of pathomechanisms of various uveitis types. This review summarizes the possible applications of OCTA and its advantages and disadvantages as opposed to dye-based angiographies in uveitic diseases. Main body Hitherto gold standards in the diagnostic workup of posterior or intermediate uveitis have been angiography on a dye-based method, which is fluorescein or indocyanine green. It gives information about the status of the blood-retinal barrier and the retinal and choroidal vasculature by visualizing diffuse leakage as a state of inflammation or complications as an ischemia or choroidal neovascularization. As noninvasive methods, fundus autofluorescence depicts the status of metabolic activity of the retinal pigment epithelium and OCT or enhanced depth imaging OCT, respectively, as a depth-resolving imaging method can supply additional information. OCTA as a non-invasive, depth-resolution imaging tool of retinal and choroidal vessels adds detailed qualitative and quantitative information of the status of retinal and choroidal vessels and bridges the gap between the mentioned conventional diagnostic tools used in uveitis. It is important, though, to be aware of its limitations, such as its susceptibility to motion artifacts, limited comparability among different devices, and restricted contribution of information regarding the grade of disease activity. Conclusion OCTA as a non-invasive, depth-resolution imaging tool can give qualitative and quantitative information about the status of retinal and choroidal vessels, but also has certain limitations. Employing OCTA as a complementary rather than exclusive tool, it can give important additional information about the macro- and microvasculature under inflammatory circumstances. Thereby, it also contributes to the understanding of the pathophysiology of various uveitis entities.

Abstract
PURPOSE Swept-source optical coherence tomography angiography (SS-OCTA) was used to measure the age-dependent changes in macular choriocapillaris (CC) flow deficits (FDs) in normal eyes. DESIGN A prospective, cross-sectional study. METHODS Subjects with normal eyes ranging in age from their 20s to their 80s were imaged using a 100-kHz SS-OCTA instrument (PLEX Elite 9000, Carl Zeiss Meditec, Dublin, California, USA). Both 3 × 3-mm and 6 × 6-mm scans were used to image the macular CC. Visualization of the CC and quantification of FDs were performed using a previously validated algorithm. The percentage of FDs (FD%) in the central 1-mm circle (C1), 1.5-mm rim (R1.5), and 2.5-mm circle (C2.5) from the 3 × 3-mm and 6 × 6-mm scans and FD% in the 2.5-mm rim (R2.5) and 5-mm circle (C5) from the 6 × 6-mm scans were measured and correlated with age and axial length. RESULTS A total of 164 subjects were enrolled, with at least 10 subjects from each decade of life. No meaningful correlations were found between FD% and axial length (|r| < 0.30). FD% in all fields increased with increasing age (all r > 0.50; all P < .001); however, the greatest increases were found in the central macula C1 regions and the smallest increases in the peripheral macula R2.5 regions. CONCLUSIONS In normal aging, the FD% increased with age across the central 5 mm of the macula, but the greatest increase was found in the central 1-mm region of the macula.

Abstract
Background Swept-source optical coherence tomography (SS-OCT) has a higher scanning rate and longer wavelength in comparison with spectral-domain OCT (SD-OCT), allowing an improved imaging of retinal vascular plexuses and choriocapillaris. The present two patients diagnosed with multiple evanescent white dot syndrome (MEWDS) underwent fundus autofluorescence (FAF), en-face SS-OCT, and SS-OCT angiography (OCTA) imaging, and its features were described and correlated. Results The clinical and imaging findings of both cases were consistent with the diagnosis of MEWDS. Color fundus photograph revealed subtle deep retinal white spots in the posterior pole and around the optic disk. FAF showed several hyperautofluorescent lesions corresponding topographically to the subtle deep retinal white lesions observed on color fundus photographs. Cross-sectional SS-OCT showed disruption of the ellipsoid zone (EZ) within the macular area in all study patients. En-face SS-OCT at the level of the outer retina showed lower reflectivity correspondent to the diffuse attenuation due to the EZ disruption on cross-sectional OCT. SS-OCTA demonstrated flow preservation within the retinal vasculature and choriocapillaris. Conclusions SS-OCT imaging allows a better visualization of the choriocapillaris, and its normal appearance in MEWDS may suggest that the outer retina and photoreceptors represent the primary site of inflammation.

Abstract
A 30-year-old woman with photopsias and decreased vision was diagnosed with multiple evanescent white dot syndrome (MEWDS) with an atypical inflammatory subfoveal retinal pigment epithelial detachment (PED) and imaged using swept-source optical coherence tomography (SS-OCT) during several visits. SS-OCT imaging revealed a focal area of attenuated choriocapillaris underneath the PED. An attempt to treat the presumed macular inflammatory lesion with corticosteroids resulted in bilateral exudation consistent with central serous chorioretinopathy.

Abstract
BackgroundMultiple evanescent white dot syndrome (MEWDS) is an inflammatory disease that can be associated with choroidalneovascularisation (CNV). However, few studies in the literature have described the occurrence of MEWDS in association with CNV. This paper discusses whether CNV can trigger MEWDS in a predisposed eye.MethodsA retrospective multicentric case series of six eyes in six patients with acute onset of MEWDS and evidence of previous CNV was conducted between January 2015 and January 2017. All patients underwent ophthalmic examination including multimodal imaging at baseline and during follow-up.ResultsThe mean age was 32.2±12.2 years. The majority of patients were women (5/1). In each case, MEWDS was diagnosed during a recurrence or occurrence of CNV secondary to choriocapillaritis, central serous chorioretinopathy or atrophic scar, presumably due to congenital toxoplasmosis. All patients were treated with intravitreal injections of antivascular endothelial growth factor (anti-VEGF) with good anatomical and functional responses (mean gain of 0.3±0.31logMAR). The mean duration of follow-up was 13.5±10.65 months.ConclusionThis study highlights a sequence in the development of MEWDS, following the occurrence or recurrence of CNV. CNV may trigger MEWDS, possibly due to the proinflammatory environment created by the retinal tissue surrounding the CNV.
