PurposeTo compare the clinical prognosis among selected white dot syndromes (WDS) (birdshot chorioretinopathy (BRC), multifocal choroiditis, serpiginous choroidopathy (SC), and others) and to identify risk factors of poor visual prognosis.MethodsRetrospective longitudinal cohort study including 84 patients (143 affected eyes) diagnosed with WDS between 1982 and July 2017, followed up until loss of follow-up or December 2017, and recruited from three Uveitis Clinics (Madrid Community, Spain). Our main outcome measures were temporary or permanent moderate (corrected visual acuity in the Snellen scale < 20/50) or severe (< 20/200) vision losses, and development of new ocular complications. Incidence rates (IR) of the main outcome measures were estimated per 100 eye-years. Bivariate and multivariate Cox robust regression models analyzed the association of demographic- and clinical-related variables with vision loss.ResultsSC exhibited the greatest IR of vision loss, even in the multivariate models. Previous events of vision loss, presence of choroidal neovascularization, and cataracts exhibited worse visual prognosis. Monotherapy with immunosuppressive drugs but not combine therapy was also associated with higher IR of visual loss. Regarding new ocular complications, BRC showed the highest IR of epiretinal membrane and macular edema.ConclusionsSC presents the worst visual prognosis. Some ocular manifestations can identify patients with WDS at risk of a worse clinical evolution.

Coronavirus disease 2019 (COVID-19) causes ocular manifestations in approximately 11% of patients. Most patients typically develop ocular symptoms within 30 days of the onset of the first COVID-19 symptoms. The most common ocular manifestation is conjunctivitis, which affects nearly 89% of patients with eye problems. Other much less common anterior segment abnormalities caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are scleritis, episcleritis, and acute anterior uveitis. Posterior segment abnormalities caused by SARS-CoV-2 are mainly vascular, such as hemorrhages, cotton wool spots, dilated veins, and vasculitis. Herein, we report a rare manifestation of COVID-19 and multiple evanescent white dot syndrome (MEWDS) of the retina. In April 2021, a 40-year-old female patient was admitted to the Eye Clinic of Clinical Center of Montenegro (Podgorica, Montenegro). The patient's main complaint was sudden vision impairment, which occurred 14 days after a positive polymerase chain reaction (PCR) test result for SARS-CoV-2 infection. A complete eye examination was performed, followed by fundoscopy, optical coherence tomography (OCT), and fluorescein angiography (FA) tests. The results showed retinal changes associated with MEWDS. The patient underwent additional examinations to rule out common causes of multifocal retinitis, all of which were unremarkable. Therefore, it was concluded that retinitis was a complication of COVID-19. Given its non-invasive nature, fundus examination should be used as a standard screening method for retinal changes in patients with COVID-19.

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.

Multiple evanescent white dot syndrome (MEWDS) is an inflammatory eye disease of the outer retina, retinal pigmented epithelium, choroid presenting with photopsia, loss of vision, and temporal scotoma. The patient was a 31-year-old female with a history of vision loss since 11 days ago (left eye). At presentation, best-corrected Snellen visual acuity was 20/140 in the Snellen chart. We decided to treat her with short time corticosteroid therapy (0.75 mg/kg/day prednisolone which was tapered in 3 weeks) for any possible rapid recovery of vision. The visual acuity of the involved eye was improved to 20/25 and 20/20, one week and three weeks after starting treatment respectively. Thus, it seems that short-term oral steroids might be an alternative method of management for patients with MEWDS.

Purpose Acute macular neuroretinopathy (AMN) can cause sudden-onset and permanent scotoma in healthy young patients. Analysis of optical coherence tomography (OCT) and OCT angiography (OCTA) of AMN patients may provide insights into disease mechanism. Methods We conducted a retrospective study of consecutive SARS-Cov-2-related AMN patients that presented in our clinic between Jan 1st, 2022, and April 30th, 2023, within 30 days of symptom onset. Retinal vessel area density (VAD) of AMN lesions in OCTA was quantified and compared to an adjacent tissue control (ATC). This quantification was performed for the superficial vascular plexus (SVP), the intermediate capillary plexus (ICP), the deep capillary plexus (DCP), the choriocapillaris (CC), and choroid. Furthermore, en face OCT images were analyzed. Results Nine AMN patients were identified, 6 of these (4 female, 2 male, average age 25 years) fulfilled the inclusion criteria and were included into this study. Average time from symptom onset to OCTA was 14.3 days. No VAD differences between AMN and adjacent tissue were found in either retinal layer (SVP, ICP, DCP). In contrast, VAD in CC was reduced by 27% against the ATC ( p  = 0.007) and choroidal VAD was reduced by 41% ( p  = 0.017). Further analysis of en face OCT could show that the pathognomonic infrared hyporeflectivity in AMN is caused by photoreceptor alterations rather than changes in the inner retinal layers. Conclusions Our data suggests that a perfusion deficit in the choroidal layers is responsible for AMN rather than in the DCP, which is the predominant hypothesis in current literature.

Abstract 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.

Background Multiple evanescent white dot syndrome (MEWDS) is a rare transient inflammatory retinopathy characterized by discrete white dots disseminated on the fundus. Focal scleral nodule (FSN) typically presents as a stable, solitary, yellow-white, subretinal lesion arising from the sclera. This article reports a rare case of MEWDS associated with FSN in a young female. Case presentation A 34-year-old female presented with a complaint of gradually enlarging paracentral scotomas in the left eye for 8 days. At presentation, best-corrected visual acuity (BCVA) was 20/25 in the left eye. Fundus examination of the left eye revealed optic disc edema and an orange-yellow irregular lesion on the infratemporal side of the fovea. The multimodal imaging (MMI) findings revealed a rather typical MEWDS-like reaction and a subretinal lesion located at the sclera. After thorough consideration, the patient was diagnosed with MEWDS associated with FSN. Corticosteroid therapy was then administered to the patient. After 11 weeks, her BCVA recovered to 20/20 in the left eye, and the visual field defect had improved. Additionally, the MEWDS-like reaction had significantly recovered. The FSN remained stable during the 18-month follow-up. Conclusions This is the first reported case of MEWDS associated with FSN, expanding the understanding of both conditions.

We present a 65-year-old woman who developed sudden and severe vision loss in her left eye one day after the administration of the second dose of COVID vaccine. The best corrected visual acuity in this eye was 1/10. Diffuse paracentral acute middle maculopathy was detected on spectral domain optical coherence tomography (OCT). OCT angiography images revealed concurrent vascular flow defects consistent with acute macular neuroretinopathy in the deep retinal capillary plexus and choriocapillaris layers. At the end of the six-month follow-up, there was no improvement in visual acuity, and atrophy and thinning developed in all layers of the retina.
