Application of Ophthalmic Electrophysiology in Inflammatory Disorders of Retina and Optic Nerve.

This review covers the utility of electrophysiological studies relevant to inflammatory diseases of the retina in conditions such as acute posterior multifocal placoid pigment epitheliopathy, acute zonal occult outer retinopathy, Adamantiades-Behçet disease, autoimmune retinopathy and neuro-retinopathy, birdshot chorioretinopathy, multiple evanescent white dot syndrome, and Vogt-Koyanagi-Harada disease. Electrophysiological studies can help with the diagnosis, prognostication, evaluation of treatment effects, and follow-up for these conditions.

EOG and the En-Face Inner Segment/Outer Segment-Ellipsoid Complex Image in Multiple Evanescent White Dot Syndrome.

Introduction: This study presents a rare case of multiple evanescent white dot syndrome (MEWDS) with atypical electrooculogram (EOG) findings, as well as abnormal en-face images of minimum intensity projection (Min-IP) and the en-face inner segment/outer segment-ellipsoid complex. Methods: A 25-year-old female patient presented with painless visual impairment and photopsia in her right eye for a duration of two days. Multimodal imaging was employed including color fundus photography (CFP), fundus autofluorescence (FAF), spectral-domain optical coherence tomography (SD-OCT), and optical coherence tomography angiography (OCTA), and en-face images of Min-IP and the en-face inner segment/outer segment-ellipsoid complex were performed. Results: In the right eye, multifocal small white spots were observed surrounding the posterior pole and optic disc of retina with the granular appearance of the fovea. FAF displayed of hyperfluorescence. SD-OCT appearance of MEWDS demonstrated primarily disrupted ellipsoid zone (EZ), photoreceptor outer segments, and interdigitation zone (IZ) complex within the fovea. The en-face images of the inner segment/outer segment-ellipsoid complex and Min-IP exhibited hyperreflective spots in the right eye. In the left eye, interestingly, hyperreflective spots were also observed on the en-face image of the inner segment/outer segment-ellipsoid complex. EOG revealed an Arden ratio of 2.5 for the right eye, while the left eye exhibited an Arden ratio of 1.7. Conclusion: The en-face image of the inner segment/outer segment-ellipsoid complex in MEWDS exhibits aberrant features and it is noteworthy that a similar alteration may occur in the fellow eye. Further investigation is required to explore the relationship between MEWDS and EOG. The en-face images of the inner segment/outer segment-ellipsoid complex and Min-IP may help to elucidate the pathogenesis of MEWDS.

Long-Term Clinical Course and Treatment Outcomes in Occult and Overt Acute Zonal Outer Retinopathy.

PURPOSE: To report the longitudinal outcomes for AZOOR patients including treatment response, imaging evolution, and overlap with multiple evanescent white dot syndrome (MEWDS). METHODS: Visual acuity (VA) and visual field (VF) outcomes of occult and overt AZOOR patients were retrospectively compared between the first and final visits as well as between the two AZOOR subtypes. For treated patients, rates of VA change and fundus lesion area were compared before and after treatment. Analyses were performed using STATA 17. RESULTS: Seventeen eyes from 11 occult AZOOR patients and 45 eyes from 29 overt AZOOR patients were included. In a composite VA/VF primary outcome, clinical improvement was noted in five occult AZOOR and three overt AZOOR patients. The decline of logarithm of the Minimal Angle of Resolution (logMAR) VA was minimal in both groups: 0.00016 units/month in occult AZOOR patients and 0.009 units/month in overt AZOOR patients (p = 0.94). Occult AZOOR patients were more likely to have improved or stable VF than overt AZOOR patients (p = 0.04). One occult AZOOR and two overt AZOOR patients developed MEWDS at subsequent visits. Treatment with steroids or immunomodulatory therapy (IMT) was initiated in one occult AZOOR patient and nine overt AZOOR patients. Treated patients had overall VA stability. Fundus lesion area in treated patients changed by a mean of 0.2831 mm2/month, with 40% of patients showing decreased lesion area. CONCLUSION: AZOOR patients generally maintained their VA. Overt AZOOR patients were more likely to receive steroids or IMT; treatment was associated with stabilization of VA.

Multiple evanescent white dot syndrome associated with COVID-19 infection: a case report.

BACKGROUND: To report a case of Multiple Evanescent White Dot Syndrome (MEWDS) one month after a COVID-19 infection in a female patient at an age unusual for the occurrence of this disease. CASE PRESENTATION: A 69-year-old Caucasian female reported the presence of floaters, photopsia, and enlarging vision loss in her left eye following the COVID-19 infection. Clinical and multimodal imaging was consistent with the MEWDS diagnosis. Fluorescein angiography examination revealed characteristic hyperfluorescent spots around the fovea in a wreath-like pattern. An extensive lab workup to rule out other autoimmune and infectious etiologies was inconclusive. Visual acuity and white dots resolved after a course of corticosteroids, which was confirmed on follow-up dilated fundus exam and multimodal imaging. CONCLUSIONS: MEWDS is a rare white dot syndrome that may occur following COVID-19 infection in addition to other reported ophthalmic disorders following this infection.

Comprehensive insights into COVID-19 vaccine-associated multiple evanescent white dot syndrome (MEWDS): A systematic analysis of reported cases.

Considering the widespread use of COVID-19 vaccines as a preventive measure against the spread of the virus, it's necessary to direct attention to the adverse effects associated with vaccines in a limited group of populations. Multiple evanescent white dot syndrome (MEWDS) following COVID-19 vaccination is a rare adverse reaction associated with COVID-19 vaccines. In this systematic review, we collected 19 articles with 27 patients up to November 1, 2023, summarizing the basic information, clinical manifestations, examinations, treatments, and recoveries of the 27 patients. The 27 enrolled patients (6 males, 21 females) had a median age of 34.1 years (15-71 years old) and were mainly from 5 regions: Asia (8), the Mediterranean region (8), North America (7), Oceania (3) and Brazil (1). Symptoms occurred post-first dose in 9 patients, post-second dose in 14 (1 with symptoms after both), post-third dose in 1, and both post-second and booster doses in 1, while details on 2 cases were not disclosed. Treatments included tapered oral steroids (6), topical steroids (3), tapered prednisone with antiviral drugs and vitamins (1), and valacyclovir and acetazolamide (1), while 16 received no treatment. All patients experienced symptom improvement, and nearly all patients ultimately recovered. Moreover, we summarized possible hypotheses concerning the mechanism of COVID-19 vaccine-associated MEWDS. The findings provide insights into the clinical aspects of COVID-19 vaccine-associated MEWDS. More attention should be given to patients with vaccine-associated MEWDS, and necessary treatment should be provided to patients experiencing a substantial decline in visual acuity to improve their quality of life.

The Characteristics of White Dot Syndromes Following SARS-COV-2 Infection: A Systematic Review.

PURPOSE: To review all studies reporting the occurrence of white dot syndromes (WDSs) following SARS-COV-2 infection. METHODS: On May 12, 2023, we registered our protocol on PROSPERO [registration number: CRD42023426012]. Five different databases including PubMed, Scopus, Web of Science, Google Scholar, and Science Direct were searched up to May 2023. We included all studies that reported the symptoms of WDSs following SARS-COV-2 infection. The data was extracted using a uniform Excel extraction sheet. All statistical tests were conducted with a 95% confidence interval and a 5% error margin. A p-value of less than 0.05 was considered statistically significant. The publication bias of included studies was assessed using JBI Critical Appraisal Checklist for Case Reports and IHE Quality Appraisal Checklist for Case Series studies. RESULTS: This review included thirty-two studies involving forty-eight patients. Acute macular neuroretinopathy was the most common disease (70.8%) followed by multiple evanescent white dot syndrome (14.6%) with 58.3% of WDS after their first SARS-COV-2 infection, and paracentral acute middle maculopathy (4.1%). They were mostly unilateral (56.2%). The presenting symptoms were blurred vision (70.8%), visual field disturbance (68.7%), and photopsia (20.8%). About 35.4% of the patients improved by their treatment and future complications were persistent scotoma (4.2%) and macular edema (2.1%). CONCLUSION: White dot syndromes are very rare entities. Our findings suggest a possible association between white dot syndrome onset and SARS-COV-2 infection. We recommend ophthalmologists should be aware of this suggested association to deliver better management and patients' care.

Clinical features and possible pathogenesis of multiple evanescent white dot syndrome with different retinal diseases and events: a narrative review.

Multiple evanescent white dot syndrome (MEWDS) is a rare fundus disease, characterized by acute vision loss and visual field defects. Many previous studies have explained the possible pathogenesis and clinical features of primary MEWDS. However, as the number of reported cases increases, secondary MEWDS occurs in other related retinal diseases and injuries, exhibiting some special characteristics. The associated retinal diseases include multifocal choroiditis/punctate inner choroidopathy (MFC/PIC), acute zonal occult outer retinopathy, best vitelliform macular dystrophy, pseudoxanthoma elasticum, and ocular toxoplasmosis. The related retinal injury is laser photocoagulation, surgery, and trauma. Although primary MEWDS often have a self-limiting course, secondary MEWDS may require treatment in some cases, according to the severity of concomitant diseases and complications. Notably, MEWDS secondary to MFC/PIC that is prone to forming choroidal neovascularization and focal choroidal excavation, needs positive treatment with corticosteroids. The possible underlying pathogenesis of secondary MEWDS is the exposure of choroidal antigen after the disruption of Bruch's membrane. The MEWDS-related features in secondary MEWDS are still evanescent under most circumstances. Its prognosis and treatment depend on the severity of complications. Current studies propose that the etiology is associated with immune factors, including viral infection, inflammation in choroid and Bruch's membrane, and antigen exposure caused by retinal and/or choroidal insults. More pathogenic studies should be conducted in the future. Accurate diagnosis for secondary MEWDS could benefit patients in aspects of management and prognosis.

The characteristics of white dot syndromes following COVID-19 Vaccines: a systematic review.

PURPOSE: To review all studies reporting the onset of white dot syndromes following COVID-19 vaccines. METHODS: Our protocol was registered prospectively on PROSPERO [registration number: CRD42023426012]. We searched five different databases including PubMed, Scopus, Web of Science, Google Scholar, and Science Direct up to May 2023. All the studies that reported the occurrence of white dot syndrome following COVID-19 vaccines were included. All statistical tests were conducted with a 95% confidence interval and a 5% error margin. A p value of less than 0.05 was considered statistically significant. The methodological quality of included studies was performed using the IHE Quality Appraisal Checklist for Case Series studies and JBI Critical Appraisal Checklist for Case Reports. RESULTS: Fifty studies involving seventy-one subjects were included. Multiple evanescent white dot syndrome (MEWDS) was the most common disease (n = 25, 35.2% %), followed by acute macular neuroretinopathy (AMN) (n = 22, 31.0%) and acute posterior multifocal placoid pigment epitheliopathy (APMPPE) (n = 4, 5.6%). They were mostly unilateral (n = 50, 70.4%). The presenting symptoms were blurred vision (n = 26, 36.6%), paracentral scotoma (n = 19, 26.8%), visual field disturbance, and photopsia (n = 7, 9.9%). The mean duration for follow-up was 10.15 ± 14.04 weeks. Nineteen subjects (29.69%) received steroids with improvement reported in 68.4%. Eleven subjects (17.19%) were managed by observation only with reported full recovery and improvement. CONCLUSION: White dot syndromes are very rare entities. Our findings highlight a possible association between COVID-19 vaccines and the occurrence of white dot syndromes. However, larger studies with good quality should be implemented to confirm these findings.

White Dot Syndromes: Report of Three Cases.

Introduction: The term white dot syndromes has been used to refer conditions that differ in their morphology and prognosis. We report three cases of different pathologies encompassed within the white dot syndromes. Case Presentations: Case 1: A 26-year-old female presented with scotoma in her right eye. Fundus examination revealed multiple white dots that demonstrated early hyperfluorescence with late staining on FA. OCT showed discontinuities in inner segment-outer segment junction associated with columnar-shaped outer retinal hyperreflective bands. AF revealed multiple hyperautofluorescent dots around the posterior pole, compatible with multiple evanescent white dot syndrome. The symptoms improved without treatment. Case 2: A 16-year-old male presented with retinal lesions compatible with punctate inner choroidopathy in his right eye. OCT showed lesion in the outer retinal layer. FAF revealed parafoveal hypoautofluorescent dots with early hyperfluorescence and late staining on FFA. After oral corticotherapy, they progress to atrophic scars. Case 3: A 65-year-old male presented with scotoma and decreased vision in his right eye. OCT showed hyperreflectivity in the outer layer that progresses to a large atrophic plaque with foveal affectation. FAF demonstrated hyperautofluorescent placoid lesion occupying macular area, compatible with acute posterior multifocal placoid pigment epitheliopathy. Retinal lesions improved with systemic corticosteroids. Conclusion: The FAF pattern helps know the distribution of the lesions. It represents a noninvasive method that has been shown to be useful in the diagnosis and monitoring of white dot syndromes.

The multimodal imaging features and outcomes of multifocal choroiditis/punctate inner choroidopathy lesion with multiple evanescent white dot syndrome-like features: a retrospective study.

BACKGROUND: Multiple evanescent white dot syndrome (MEWDS)-like features is a rare condition triggered by a macular disease or iatrogenic injury, exhibiting MEWDS changes in the fundus. This study aims to describe the multimodal imaging features and outcomes of multifocal choroiditis/punctate inner choroidopathy (MFC/PIC) lesions with MEWDS-like features. METHODS: Six cases were studied retrospectively. All cases were given regional and oral corticosteroids. RESULTS: All cases showed an isolated juxtafoveal yellowish-white MFC/PIC lesion with disruption of RPE-Bruch's membrane-choriocapillaris complex (RPE-BM-CC), subretinal hyperreflective materials and choroidal thickening on optical coherence tomography. Two weeks after presentation, the grayish-white dots disappeared spontaneously and the corticosteroids were given. After four weeks, the ellipsoid zone (EZ) around the lesion and hyper-autofluorescence resolved. After 13 weeks, five cases showed shrinkage of the juxtafoveal lesion and restoration of foveal EZ. After six months, the juxtafoveal lesion became pigmented. Only one case developed type 2 choroidal neovascularization. CONCLUSIONS: The clinical course of MEWDS-like manifestations is still evanescent in our cases. The yellowish-white juxtafoveal MFC/PIC lesions with disruption of RPE-BM-CC and choroidal thickening showed a well-controlled prognosis after corticosteroid treatment.

Small case study of retinopathy associated with novel coronavirus infection / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To observe the clinical and multimodal imaging features of retinopathy associated with novel coronavirus disease 2019(COVID-19)infection, investigate the related risk factors, and analyze the treatment and prognosis.METHODS: A total of 7 patients(7 eyes)with clinically confirmed COVID-19-associated retinopathy in Tianjin Medical University General Hospital from December 13, 2022 to January 13, 2023 were included in the study. All patients underwent color fundus photography, IR, spectral-domain optical coherence tomography(SD-OCT), fundus autofluorescein(FAF)and other ophthalmic examination and serological examination.RESULTS: Among the included patients, 2 cases(2 eyes)of central retinal vein occlusion(CRVO)appeared differently from previous CRVO. The hemorrhagic features of CRVO were round or fusiform shape hemorrhagic spots with white centers. One of them, the von Willebrand factor antigen(vWF: Ag)level was increased to 161.8%. The other case was positive in serologic test for lupus anticoagulant. In 2 cases(2 eyes)of multiple evanescent white dot syndrome(MEWDS), FAF showed that dots of high spontaneous fluorescence were scattered in the posterior pole. The prognosis of 2 MEWDS were good after the treatment of glucocorticoids. The 3 cases(3 eyes)of acute macular neuroretinopathy(AMN)showed reddened brown lesions in the macular area, hyporeflective lesions with clear boundaries on IR, and high signal intensity in the ONL and ELM, EZ/IZ signal fracture on SD-OCT.CONCLUSION: COVID-19 may cause inflammatory storm, involving all layers of retinal tissues and blood vessels, leading to the occurrence of various retinal lesions. Hormone therapy may be effective and the prognosis is good in most cases. Roth spot can be seen in fundus hemorrhage of CRVO, lupus anticoagulant and increased vWF: Ag may be risk factors for CRVO after COVID-19.

Latest advances in white spot syndromes: New findings and interpretations.

White spot syndromes (WSS) pose challenges in the field of ophthalmology, particularly in terms of accurate diagnosis and effective management. However, recent advancements in multimodal imaging (MMI) have significantly contributed to our understanding of WSS, allowing for improved characterization of these inflammatory chorioretinopathies. By employing various imaging modalities, including fundus fluorescein angiography, indocyanine green angiography, fundus autofluorescence, optical coherence tomography (OCT), ultra-widefield imaging, and OCT angiography, researchers and clinicians have gained valuable insights into the underlying pathophysiological changes and clinical progression of WSS. Furthermore, MMI has unveiled novel and atypical variants within the spectrum of WSS, expanding our knowledge in this field. Notably, the identification of secondary forms of WSS occurring concurrently with unrelated chorioretinal disorders has suggested a potential autoimmune mechanism underlying these conditions. The introduction of MMI has also facilitated a more comprehensive evaluation of previously ill-defined entities, such as acute zonal occult outer retinopathy, leading to improved diagnostic criteria and enhanced recognition of distinct features. This review paper provides a comprehensive overview of the latest advances and interpretations in WSS. By integrating MMI into the diagnosis and management of these conditions, this review aims to enhance patient outcomes and provide valuable insights into the complexities surrounding WSS.

Unilateral Multiple Evanescent White Dot Syndrome-Like Reaction Following the CyberKnife Stereotactic Radiotherapy for Choroidal Malignant Melanoma.

A 58-year-old otherwise healthy man received a diagnosis of choroidal malignant melanoma (CMM) in June 2021 and underwent a single session of (21 Gy) CyberKnife stereotactic radiotherapy (SRT). Eleven months later, we noticed 3+ anterior chamber cells with occasional vitreous cells in the left eye. Though the tumor looked regressed, there were mild optic disc leakage, early hypofluorescent and late hyperfluorescent punctate lesions scattered 360 degrees, and late staining of the mass on fluorescein angiogram. The findings were compatible with a unilateral multiple evanescent white dot syndrome (MEWDS)-like reaction that was most likely related to CyberKnife SRT-induced tumor necrosis, and a dexamethasone implant was administered intravitreally into the left eye together with topical steroids. A second intravitreal injection of dexamethasone was given three months later due to remittance of the angiographic features. As there are only a few reports on CyberKnife SRT for the treatment of CMM, we wanted to share our interesting observation of a post-treatment MEWDS-like reaction likely related to tumor necrosis syndrome with the ophthalmic community.

Rare Case of Bilateral and Asymmetrical Multiple Evanescent White Dot Syndrome.

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. Spectral Domain Optical Coherence Tomography (SD-OCT) showed the presence of juxta foveal subretinal fluid and disrupted inner segment-outer segment (IS-OS) junction over the right eye. The patient had a spontaneous complete recovery within six weeks' time.

Multiple Evanescent White Dot Syndrome Following Adenovirus Vector-Based COVID-19 Vaccine (Covishield).

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. Her clinical findings and imaging features confirmed the diagnosis of MEWDS. Her symptoms resolved spontaneously after 2 weeks. CONCLUSION: This is the first reported case of MEWDS following an adenovirus vector-based COVID-19 vaccine. Comparison with previously reported cases of MEWDS following COVID-19 vaccination showed that patients are generally healthy, young to middle-aged women, who develop symptoms after a median time of one week and recover spontaneously over a median period of 4 weeks.

Blind spot enlargement: A differential diagnosis challenge.

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.

Topographic patterns of retinal lesions in multiple evanescent white dot syndrome.

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. RESULTS: The topographic distribution of MEWDS lesions was centered on or around the optic disc (n = 17, 59%), centered on the macula (n = 7, 24%), sectoral (n = 2, 7%), or was indeterminate (n = 3, 10%). The MEWDS episodes either occurred in the absence ('primary MEWDS'; n = 14, 48%) or presence of concurrent chorioretinal pathology ('secondary MEWDS'; n = 15, 52%). In patients with the latter, MEWDS lesions were often centered around a coexisting chorioretinal lesion. The majority of patients in both groups experienced resolution of their symptoms and retinal changes on multimodal imaging by 3 months. CONCLUSIONS: Distinct distributions of MEWDS lesions were identified. MEWDS may occur in tandem with other chorioretinal pathology, which may impact the topography of MEWDS lesions.

Optical Coherence Tomography Angiography (OCT-A) in Uveitis: A Literature Review and a Reassessment of Its Real Role.

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: The purpose of this review was aimed at examining the evidence in published reports indicating whether OCT-A could possibly replace dye angiographic methods, as well as the real practical impact of OCT-A. METHODS: A literature search in the PubMed database was performed using the terms OCT-angiography and uveitis, OCTA and uveitis and OCT-A and uveitis. Case reports were excluded. Articles were classified into technical reports, research reports and reviews. Articles in the two latter categories were analyzed in a more detailed, individual fashion. Special attention was paid to whether there were arguments in favor of an exclusive rather than complementary use of OCT-A. Furthermore, a synthesis of the main practical applications of OCT-A in the management of uveitis was attempted. RESULTS: Between 2016 (the year of the first articles) and 2022, 144 articles containing the search terms were identified. After excluding case report articles, 114 articles were retained: 4 in 2016, 17 in 2017, 14 in 2018, 21 in 2019, 14 in 2020, 18 in 2021 and 26 in 2022. Seven articles contained technical information or consensus-based terminology. Ninety-two articles could be considered as clinical research articles. Of those, only two hinted in their conclusions that OCT-A could hypothetically replace dye methods. The terms mostly used to qualify the contribution of the articles in this group were "complementary to dye methods", "adjunct", "supplementing" and other similar terms. Fifteen articles were reviews, none of which hinted that OCT-A could replace dye methods. The situations where OCT-A represented a significant practical contribution to the practical appraisal of uveitis were identified. CONCLUSION: To date, no evidence was found in the literature that OCT-A can replace the classic dye methods; however, it can complement them. Promoting the possibility that non-invasive OCT-A can substitute the invasive dye methods is deleterious, giving the elusive impression that dye methods are no longer inevitable for evaluating uveitis patients. Nevertheless, OCT-A is a precious tool in uveitis research.

Multiple Evanescent White Dot Syndrome and Choroidal Neovascularization following SARS-COV-2 Infection in a Patient on Dabrafenib and Trametinib.

PURPOSE: to describe multimodal imaging and electrophysiology of multiple evanescent white dot syndrome (MEWDS) concomitant with COVID-19 infection in a patient on BRAF (B Rapidly Accelerated Fibrosarcoma) and MEK (Mitogen-activated Protein Kinase) inhibitors. METHODS: observational case report and literature review. RESULTS: a 37-year-old woman affected by cutaneous melanoma on BRAF and MEK inhibitors developed visual symptoms in the right eye simultaneously with a SARS-COV-2 infection. The right eye visual acuity was hand movement, and clinical examination disclosed vitreous cells, yellow-white retinal spots, and macular yellowish material. Fundus autofluorescence and angiograms were consistent with MEWDS. Angiograms, optical coherence tomography, and optical coherence tomography angiography revealed a macular choroidal neovascular membrane. The infectious and inflammatory work-up was negative. Electrodiagnostic tests revealed cone dysfunction. MEWDS resolved and anti-VEGF treatment allowed partial vision recovery. CONCLUSION: the case illustrates the association of MEWDS and choroidal neovascularization developing after COVID-19 infection in the setting of immunotherapy.
