Our purpose is to describe blue-light fundus autofluorescence (BAF) features of inflammatory diseases of the outer retina characterised by photoreceptor damage. BAF from patients diagnosed with secondary and primary inflammatory photoreceptor damage were retrospectively analyzed and compared to other imaging modalities including fluorescein angiography (FA), indocyanine green angiography (ICGA), and spectral domain optical coherence tomography (SD-OCT). Multiple evanescent white dot syndrome (MEWDS), idiopathic multifocal choroiditis (MFC), acute posterior multifocal placoid pigment epitheliopathy (APMPPE), serpiginous choroiditis (SC), and acute syphilitic posterior placoid chorioretinitis (ASPPC), all cases corresponding to secondary photoreceptor diseases caused by inflammatory choriocapillaris nonperfusion, were included and compared to primary photoreceptor disease entities, including acute zonal occult outer retinopathy (AZOOR) and cancer-associated retinopathy (CAR)...

INTRODUCTION: Visual snow syndrome (VSS) is a central nervous system disorder that consists of the constant perception of small black and white dots throughout the entire visual field. DEVELOPMENT: VSS can present from infancy to old age, with greater prevalence in the young population, and shows no difference between sexes. The diagnostic criteria include the presence of visual snow and such other visual phenomena as palinopsia, photophobia, nyctalopia, and other persistent visual phenomena...

This fast, easy-to-perform, noninvasive technique can detect and manage infectious uveitis. CONCLUSIONS: FAF serves to understand pathophysiologic mechanisms of uveitis and is a valuable prognostic indicator of themselves...

The objective of this research is to identify and systematize the medical conditions generated by SARS-CoV-2 on the optic nerve and retina of young, adult, and elderly adults who suffered from COVID-19 in the period 2019-2022. A theoretical documentary review (TDR) was conducted within the framework of an investigation to determine the current state of knowledge of the subject under study. The TDR includes the analysis of publications in the scientific databases PubMed/Medline, Ebsco, Scielo and Google. A total of 167 articles were found, of which 56 were studied in depth, and these evidence the impact of COVID-19 infection on the retina and optic nerve of infected patients, both during the acute phase and in subsequent recovery...

PURPOSE: To analyze the changes of macrophage-like cells (MLCs) on the inner retinal surface associated with multiple evanescent white dot syndrome using optical coherence tomography. METHODS: Four eyes of four patients with multiple evanescent white dot syndrome were examined and followed with multimodal imaging, including optical coherence tomography angiography, to visualize MLC on en face structural projections. RESULTS: On en face structural optical coherence tomography angiography projection at presentation, all multiple evanescent white dot syndrome eyes showed a decrease of the nearest neighbor distance of MLC within the region of interest and an increase of MLC density in the perifovea compared with the fellow unaffected eye...

Acute zonal occult outer retinopathy (AZOOR) diagnosis is challenging and frequently delayed. Atypical findings were described, nevertheless optic disc edema has not been consistently reported. In this study we pretend to describe a challenging diagnosis of AZOOR. In our case, a 19-year-old female presented painless vision loss in her right eye for 2 weeks. Fundus examination revealed optic disc hyperaemic edema and the visual field (VF) an enlarged blind spot. Non-infectious optic neuritis was assumed and intravenous corticotherapy administered...

Bilateral presentation of multiple evanescent white dot syndrome (MEWDS) is a rare occurrence. We report a case of bilateral multiple evanescent white dot syndrome in a young female patient with asymmetrical manifestation. She presented with sudden onset of right eye central blurring of vision and dyschromatopsia. Fundus examination however showed bilateral multiple grey-white intra-retinal punctate lesions with an asymmetrical manifestation of the swollen optic disc and foveal granularity over the right...

UNLABELLED: Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) is classified as a part of the spectrum of the white dot syndromes affecting the inner choroid and the outer retina. It is usually bilateral and affects young patients between the second and fourth decades. The authors report an unusual case of unilateral APMPPE mimicking Vogt-Koyanagi-Harada (VKH) disease where the fundus fluorescein angiography was instrumental in confirming the diagnosis. CASE PRESENTATION: A 35-year-old male presented with decreased visual acuity in the right eye for 3 days...

PURPOSE: To report a case of multiple evanescent white dot syndrome (MEWDS) following adenovirus vector-based Coronavirus disease 2019 (COVID-19) vaccine, Covishield and to present a summary of previously reported cases of MEWDS following COVID-19 vaccines. METHODS: Retrospective case report and review of literature. RESULTS: A 22-year-old Indian female presented with blurred vision, scotomata, and photopsias in her left eye, a day after administration of second dose of Covishield vaccine...

A 68-year-old female patient was referred to our hospital with a 30-mm polyp in the second portion of the duodenum found via esophagogastroduodenoscopy. The polyp had an irregular, lobular surface and a thick stalk. In addition, white dots were detected on the surface. Magnifying endoscopy with narrow-band imaging showed a white material deep in the loop-shaped microvessels on the white dots. Endoscopic ultrasonography showed a hypoechoic elevated lesion from the mucosal layer, and a feeding vessel traversing the stalk to supply the head of the polyp...

PURPOSE: To demonstrate different topographic distributions of multiple-evanescent white dot syndrome (MEWDS) and secondary MEWDS disease and to describe possible associations. METHODS: Clinical evaluation and multimodal retinal imaging in 27 subjects with MEWDS (29 discrete episodes of MEWDS). Ophthalmic assessment included best-corrected visual acuity testing and multimodal retinal imaging with OCT, blue-light autofluorescence, fluorescein and indocyanine green angiography, fundus photography, and widefield pseudocolor and autofluorescence fundus imaging...

A 39-year-old woman, without any systemic or ocular history, presented with a paracentral scotoma in her right eye with normal visual acuity. Humphrey's visual fields showed a reversible enlargement of the right blind spot. The final diagnosis was acute idiopathic blind spot enlargement which was successfully treated with intravenous steroids. Although differential diagnosis of blind spot enlargement can be challenging, multimodal imaging with combination of visual field's assessment can help us make the right diagnosis...

PURPOSE: To present and compare the clinical features and multimodal imaging (MMI) findings of the primary form of multiple evanescent white dot syndrome (MEWDS) and MEWDS secondary to multifocal choroiditis/punctate inner choroidopathy (MFC/PIC). METHODS: A prospective case series. Thirty eyes of 30 MEWDS patients were included and divided into the primary MEWDS group and MEWDS secondary to MFC/PIC group. Demographic, epidemiologic, and clinical characteristics and MEWDS-related MMI findings of the two groups were compared...

BACKGROUND: The global and precise follow-up of uveitis has become possible with the availability of dual fluorescein (FA) and indocyanine green angiography (ICGA) since the mid-1990s. Progressively, additional non-invasive imaging methods have emerged, bringing value-added precision to the imaging appraisal of uveitis, including, among others, optical coherence tomography (OCT), enhanced-depth imaging OCT (EDI-OCT) and blue light fundus autofluorescence (BAF). More recently, another complementary imaging method, OCT-angiography (OCT-A), further allowed retinal and choroidal circulation to be imaged without the need for dye injection...

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...

RATIONALE: Multiple evanescent white dot syndrome (MEWDS) is characterized by multiple white dots in the posterior pole of the eye, but its diagnosis can be difficult in cases when the white dots are not visible. We report an atypical case of MEWDS that developed in pathologic myopia. PATIENT CONCERN: A 42-year-old woman presented with floater and reduced and distorted vision in the right eye that she noted 3 days earlier. DIAGNOSIS: The right eye was highly myopic at -17...
