RESUMEN
This case report describes a new type of perifoveal retinal vascular abnormality (RVA) incidentally discovered during a posterior vitreous detachment (PVD) investigation. A 65-year-old woman with sudden central visual loss displayed a unilateral focal telangiectatic venule in the perifoveal area. Multimodal imaging documented the vascular abnormality and associated retinal changes. Despite symptom resolution, the RVA persisted. This case represents a unique presentation of perifoveal RVA, likely an atypical form of macular telangiectasia. The sequential imaging documentation during a process of PVD with central bouquet traction provides insights into the underlying mechanisms in addition to diagnosing and monitoring perifoveal RVAs.

RESUMEN
BACKGROUND: First described by Gaucher and associates in 2008, dome-shaped macula (DSM) is an anterior convex protrusion of the macula visible on OCT (optical coherence tomography). Visual impairment in DSM results mainly from sub-foveal serous retinal detachment (SRD). Herein, this original study from retrospective data analysis evaluate the anatomical and functional effects of Pascal® short-pulse (SP) laser plus endpoint management (EpM) subthreshold diffuse laser (SDL) in patients with SRD due to DSM. METHODS: This retrospective study included seven consecutive patients (eight eyes) with SRD secondary to dome-shaped macula who underwent a comprehensive ophthalmological evaluation including logMAR BCVA, slit-lamp biomicroscopy, indirect ophthalmoscopy, and spectral-domain optical coherence tomography (SD-OCT) (Spectralis; Heidelberg Engineering, Germany) before combined Pascal® SP laser plus EpM-SDL with 1 to 6 month intervals, postoperatively, with a mean ± standard error (SE) follow-up time of 12.92 ± 1.34 months. RESULTS: Eight eyes from seven patients were analyzed in this study. At baseline, mean BCVA (LogMAR) ± standard error (SE) and mean CST (central subfield thickness)(µm) ± SE were 0.6125 ± 0.14 and 412.50 ± 24.65, respectively. After a mean follow-up time of 12.92 ± 1.34 months, mean CST (µm) ± SE and BCVA (LogMAR) ± SE were 294.75 ± 19.68 (p = 0.0078) and 0.4537 ± 0.12 (p = 0.0313), respectively. A statistically significant reduction in mean CST and an improvement in mean BCVA were noted after SRD resolution with laser therapy application. The mean serous retinal detachment resolution time (months) ± SE was 3.75 ± 1.08. No adverse events were registered, including enlargement of atrophic alterations and choroidal neovascularization. CONCLUSIONS: The novel combined laser modality with Pascal® SP laser plus EpM-SDL treatment may induce subretinal fluid regression and BCVA improvement 1 year after treatment in DSM patients with SRD.
RESUMEN
BACKGROUND: We believe that our experience with patients presenting with Coats disease and macular sparing should be shared with our colleagues. We would like to show the effect of posture and prompt intervention in cases with fovea-threatening and/or fovea-involving peripheral Coats disease (FTPCD). This association has been poorly debated in our specialty and literature. We call the attention for the unexpexted scenario of observing the lost of the fovea during some types of traditional and prompt interventional treatments of these cases with previous 20/20 vision (something that we have been studying and observing for many years). In order to publish our best representative cases, we have chosen 8 Brazilian patients (age range, 7-62 years; 5 male) with FTPCD. All patients underwent multimodal imaging and different treatments (observation, sleep-posture repositioning, laser, intraocular steroids, and/or anti-vascular endothelial growth factor therapy). All patients, initially, informed to adopt a sleeping lateral-down position, favoring exudation shifting to the fovea pre-treatment. Most promptly-treated patients in this way (n = 4), developed subretinal fluid and exudates in the macula and some had irreversible central visual loss (n = 3). Patients with recent fovea-involving exudation who changed postural sleep position (to protect the foveal area) before and during treatment fared better, with some preserved central vision and an intact fovea (n = 5). The fundus status was correlated with the gravitational effects of posture before and after treatment. Despite prepared as an observational/interventional study, with a small number of cases, the most difficult part is documenting the sleep position of these patients and its influence in the outcomes as there is not good way to prove how well or poorly the positioning occurred in our cases. Finally, we also intended to call the attention to the fact that Coats disease must be studied in all its clinical stage variants and not only seen as a potential blinding and incurable ocular disease. CASE PRESENTATION: This study is a retrospective and/or interventional analysis of eight cases with a less severe clinical variant of classic Coats disease that we refer to as fovea-threatening and fovea-involving peripheral Coats disease (FTPCD). All cases were unilateral with no systemic disease or family history of Coats disease. The bilateral anterior segment and intraocular pressure were normal in all patients. The characteristics of all patients are shown in the Table. CONCLUSION: The funduscopic features of FTPCD are fundamental to disease understanding and optimal management. Habitual posturing may affect the fundus morphologic features of retinal exudation as observed in all current patients with exudative peripheral Coats disease. When sleep habitual posture is not observed in patients with FTPCD, the effects of prompt invasive treatments can cause rapid visual loss because of foveal subretinal pooling of exudates post-treatment. Initial vigilant adjusting of the habitual sleep posture for several patients with FTPCD, before the indication of traditional invasive treatments (laser and/or pharmacologic medications) can result in improved vision and fundoscopic morphologic features.
RESUMEN
PURPOSE: To present a case of an atypical unilateral multifocal choroiditis that occurred in temporal association to an acute covid-19 infection. METHOD: A 23-year-old highly myopic man presented with reduced vision in the right eye while under medical quarantine due to direct exposure to COVID-19 infection. Five days after developing mild COVID symptoms (fever, cough and anosmia) he noticed acute painless loss of central vision in his right eye. Systemic evaluation at presentation was positive for SARS-CoV-2 detected via both a pharyngeal swab and serologic titers. Dilated fundus exam was performed, followed by color fundus pictures, optic coherence tomography (OCT), fundus autofluorescence (FAF) and fluorescein angiography (FA). RESULTS: Fundoscopic examination of the right eye revealed the presence of multiple discrete, slightly elevated yellow-whitish placoid lesions at the posterior pole. The visual acuity was 20/800. The left eye was normal with 20/20 vision. The patient was placed on oral corticosteroids and the lesions rapidly improved. CONCLUSION: The patient had an MFC chorioretinitis around the same time that he had a documented acute covid infection. Though the temporal relationship could be by chance alone, communicating this case to the ophthalmic community is warranted to see if other similar cases are noted.
RESUMEN
Importance: Congenital retinal macrovessel (CRM) is a rarely reported venous malformation of the retina that is associated with venous anomalies of the brain. Objective: To study the multimodal imaging findings of a series of eyes with congenital retinal macrovessel and describe the systemic associations. Design, Setting, and Participants: In this cross-sectional multicenter study, medical records were retrospectively reviewed from 7 different retina clinics worldwide over a 10-year period (2007-2017). Patients with CRM, defined as an abnormal, large, macular vessel with a vascular distribution above and below the horizontal raphe, were identified. Data were analyzed from December 2016 to August 2017. Main Outcomes and Measures: Clinical information and multimodal retinal imaging findings were collected and studied. Pertinent systemic information, including brain magnetic resonance imaging findings, was also noted if available. Results: Of the 49 included patients, 32 (65%) were female, and the mean (SD) age at onset was 44.0 (20.9) years. A total of 49 eyes from 49 patients were studied. Macrovessel was unilateral in all patients. Color fundus photography illustrated a large aberrant dilated and tortuous retinal vein in all patients. Early-phase frames of fluorescein angiography further confirmed the venous nature of the macrovessel in 40 of 40 eyes. Optical coherence tomography angiography, available in 17 eyes (35%), displayed microvascular capillary abnormalities around the CRM, which were more evident in the deep capillary plexus. Of the 49 patients with CRM, 39 (80%) did not illustrate any evidence of ophthalmic complications. Ten patients (20%) presented with retinal complications, typically an incidental association with CRM. Twelve patients (24%) were noted to have venous malformations of the brain with associated magnetic resonance imaging. Of these, location of the venous anomaly in the brain was ipsilateral to the CRM in 10 patients (83%) and contralateral in 2 patients (17%), mainly located in the frontal lobe in 9 patients (75%). Conclusions and Relevance: Our study has identified an association between macrovessels in the retina and venous anomalies of the brain (24% compared with 0.2% to 6.0% in the normal population). Thus, we recommend new guidelines for the systemic workup of patients with CRM to include brain magnetic resonance imaging with contrast. These lesions may be more accurately referred to as retinal venous malformations, which may raise awareness regarding potential cerebral associations.

A 70-year-old woman presented with 20/200 visual acuity in the right eye. Multimodal imaging revealed tilted disc syndrome (TDS) with macular serous detachment (MSD) and pigmentary changes at the temporal margin of the optic disc. Subretinal fluid persisted after three monthly intravitreal bevacizumab (Avastin; Genentech, South San Francisco, CA) injections and threshold focal laser photocoagulation. Subsequently, confluent subthreshold argon laser was applied over the entire area of retinal pigment epithelium (RPE) abnormalities, resulting in the resolution of subretinal fluid without recurrence through 3 years of follow-up. Subthreshold argon laser treatment may serve as a therapeutic option for MSD in TDS. Targeting leakage sites and stimulating RPE cells might help absorb subretinal fluid.

BACKGROUND: To report the presence of transient peripapillary serous detachments in multiple evanescent white dot syndrome. METHODS: Retrospective case series. RESULTS: Four eyes of four patients diagnosed with multiple evanescent white dot syndrome presented with peripapillary serous detachments. Diagnosis was based on clinical presentation, fundus findings, and angiographic findings. All 4 were female with age ranges between 24 and 40 years and presented with photopsias, an enlarged scotoma contiguous with the blind spot, and chorioretinal white dots in the posterior pole with characteristic angiographic features. All of the serous detachments resolved or were greatly reduced concomitantly with the resolution of the patient's other clinical symptoms and fundus findings. CONCLUSION: The authors report peripapillary serous detachments as a previously unreported manifestation of multiple evanescent white dot syndrome. These seem to be self limited with concurrent resolution with the rest of the patient's symptoms.

Hemorrhagic complications of optic pathway diseases are extremely rare causes of acute visual loss associated with dengue fever. In this paper we report a patient presenting with dengue fever and bilateral acute visual loss caused by chiasmal compression due to Rathke's cleft cyst apoplexy. Considering the importance of early diagnosis and treatment to visual recovery, apoplexy of sellar and suprasellar tumors should be considered in the differential diagnosis of patients with acute visual loss and dengue fever.
RESUMEN
We report a case of a 19-year-old woman presenting bilateral neurosensorial hearing loss, mental abnormalities, and loss of visual field in the left eye. Visual acuity was 20/20 in OD and 20/25 in OS. Patient was examined systemically. Audiometry showed sensorineural hearing loss in both ears. The magnetic resonance imaging (MRI) of brain revealed multiple small lesions in the white matter in both cerebral hemispheres and at the corpus callosum. Fundoscopy showed bilateral normal optic disc and sheathing of the arterioles in the middle periphery of OD. Retinal edema and cotton-wool spots were observed. Fluorescein angiography showed bilateral peripheral occlusive arterial vasculopathy. The patient was diagnosed with Susac syndrome and treated with quetiapine fumarate, flunitrazepam, and prednisone, which resulted in stabile outcome. This case shows that a high index of suspicion leading to early recognition and treatment is important to avoid irreversible damage.

Relatamos o caso de uma mulher de 19 anos apresentando perda auditiva neurossensorial bilateral, anormalidades mentais e perda de campo visual no olho esquerdo. A acuidade visual era 20/20 em OD e 20/25 em OE. Paciente foi sistematicamente investigada, audiometria mostrou perda auditiva neurossensorial nos dois ouvidos e ressonância magnética nuclear (RNM) cerebral mostrou múltiplas pequenas lesões na substância branca em ambos os hemisférios cerebrais e no corpo caloso. A fundoscopia mostrou disco óptico normal bilateral, e embainhamento das arteríolas na média periferia do olho direito. Edema de retina e exsudatos algodonosos foram vistos. Angiofluoresceinografia mostrou vasculopatia arterial obstrutiva periférica bilateral. A paciente foi diagnosticada com síndrome Susac e tratada com fumarato de quetiapina, flunitrazepam e prednisona resultando em estabilização do quadro. Este caso mostra que um alto índice de suspeita levando ao reconhecimento precoce e tratamento é importante para evitar o diagnóstico tardio.

Our purpose is to report a case of diffuse unilateral subacute neuroretinitis (DUSN) in which an ophthalmoscopically visible worm was found and optical coherence tomography (OCT) scans allowed the precise localization of the parasite in the intraretinal layers. Our findings suggest that the parasite moves in the inner portions of the retina possibly explaining the severe degenerative neural changes that it causes.
Nosso objetivo é relatar um caso de neurorretinite subaguda unilateral difusa (DUSN), onde uma larva oftalmoscopicamente visível foi detectada e, através do escaneamento pela tomografia de coerência óptica (OCT), foi possível estabelecer a localização precisa do parasita entre as camadas da retina. Nossos resultados sugerem que o movimento do parasita nas camadas mais internas da retina possa explicar as graves alterações neuronais degenerativas encontradas.

PURPOSE: To report the findings of optical coherence tomography (OCT) in three cases of diffuse unilateral subacute neuroretinitis (DUSN). METHODS: Three young patients with confirmed diagnosis of diffuse unilateral subacute neuroretinitis were followed-up using Stratus OCT. RESULTS: Optical coherence tomography findings included retinal nerve fiber layer atrophy and focal edema where the worm was initially lodged. In two patients we could identify the worm by optical coherence tomography as an area of hiper-reflectivity. The worms were laser photocoagulated and post-treatment optical coherence tomography scanning revealed improvement of edema, nerve fiber layer thinning and a retinal hyper-reflectivity where laser had been applied. CONCLUSION: The main finding reported here is the potential of optical coherence tomography in detecting the presence of retinal nerve fiber layer atrophy and focal retinal edema in areas affected by the worm. Optical coherence tomography can be used to distinguish diffuse unilateral subacute neuroretinitis from other mimicking diseases like punctate outer retinitis, when there are no retinal fiber layer atrophy.

OBJETIVO: Demonstrar os achados da tomografia de coerência óptica em três casos de neurorretinite subaguda difusa unilateral (DUSN). MÉTODOS: Os pacientes com diagnóstico confirmado de neurorretinite subaguda difusa unilateral realizaram seguimento pré e pós-tratamento por meio da tomografia de coerência óptica, Stratus® OCT. RESULTADOS: Os achados marcantes da tomografia de coerência óptica foram a atrofia das camadas de fibras nervosas da retina e edema da retina localizado em áreas nas quais a larva esteve. Em dois pacientes pôde-se localizar a larva no espaço sub-retiniano por meio da tomografia de coerência óptica, que se traduziu por pequena área densa (hiperrefletividade). As larvas foram fotocoaguladas a laser e os achados da tomografia de coerência óptica após o tratamento demonstrou melhora do edema, afinamento das camadas de fibras nervosas e hiperrefletividade no local da aplicação do laser. CONCLUSÃO: Os principais achados na tomografia de coerência óptica foram a atrofia difusa das camadas de fibras nervosas e o edema localizado nas áreas afetadas pela larva. A tomografia de coerência óptica pode ser usado para diferenciar neurorretinite subaguda difusa unilateral de doenças que a simulam, como retinite punteada externa, que não manifesta alterações das camadas de fibras nervosas.
