PURPOSE: To report a case of acute macular neuroretinopathy in a patient with Susac syndrome. METHODS: Case report. RESULTS: A 39-year-old male patient presented with severe headache, photopsias, and a sudden onset of hearing loss in the right ear. Fluorescein angiography of the right eye revealed multiple branch retinal artery occlusions. Clinical presentation of encephalopathy, hearing loss, and branch retinal artery occlusions, along with characteristic magnetic resonance imaging findings, led to a diagnosis of Susac syndrome...

Purpose: We report a case of acute macular neuroretinopathy (AMN) following routine annual inactivated influenza vaccination. Projection-resolved optical coherence tomography angiography (PR-OCTA) was used to analyze the retinal capillary flow within the AMN lesion. Observations: Our patient reported visual symptoms of her right eye nine days after routine annual influenza vaccination. Multimodal imaging revealed small vessel peripheral vasculitis and AMN in the affected eye...

PURPOSE: To present a series of idiopathic paracentral acute middle maculopathy (PAMM) and acute macular neuroretinopathy (AMN) cases and to compare the microvascular retinal status of PAMM/AMN eyes with those of healthy individuals. METHODS: Six eyes with PAMM and two eyes with AMN in a total of six patients were included in this study. Multimodal retinal imaging, including optical coherence tomography angiography, was performed in all patients. The vessel density of the superficial capillary plexus and deep capillary plexus, as well as the area, circularity, and angle of the superficial foveal avascular zone (FAZ) were measured and compared with the same parameters in age-matched healthy individuals...

PURPOSE: To document directional reflectivity of fundus lesions in a case of acute macular neuroretinopathy. METHODS: Case report. Clinical and imaging data from a patient with acute macular neuroretinopathy were reviewed. Imaging comprised infrared scanning laser ophthalmoscopy, optical coherence tomography and flood-illumination adaptive optics images acquired through different entry pupils in the cardinal directions (approximately 2° eccentricity). RESULTS: The patient reported acute bilateral paracentral scotoma revealing dark, wedge-shaped macular plaques which by optical coherence tomography were associated with focal loss of the visibility of the cone outer segment tip and inner/outer segment lines...

A 19-year-old Caucasian woman developed an upper respiratory infection, took a cold formulation containing 5 mg of phenylephrine, and developed a very rare and unusual form of acute macular neuroretinopathy (AMN) that could not be detected on fundoscopic examination, visual fields, nor electrophysiological testing. Spectral-domain optical coherence tomography (SD-OCT) revealed a lesion limited to the fovea. This case illustrates the value of SD-OCT, in light of otherwise normal testing, in a variant of AMN the authors call "occult AMN"...

PURPOSE: To report the clinical findings of the youngest confirmed case of acute macular neuroretinopathy to the best of our knowledge. METHODS: A 9-year-old patient describing a paracentral scotoma with a normal clinical examination and normal fluorescein angiography. RESULTS: Initial fundus examination was unremarkable. Fluorescein angiography findings showed no abnormalities but scotoma was confirmed using Amsler grid. Optical coherence tomography showed a parafoveal hyperreflective band in the outer layers...

A 39-year-old female with dengue fever presented with decreased vision in both eyes. Visual acuity was 20/200 and 20/80 in the right eye (OD) and left eye (OS), respectively. Fundus showed granular, grayish-white lesions in the parafoveal region in OD. Multimodal imaging including optical coherence tomography angiography (OCTA), optical coherence tomography (OCT), and fluorescein angiography (FA) was performed. FA showed late hyperfluorescence with few microaneurysms in OS. OCT showed hyperreflectivity in various layers, suggestive of acute macular neuroretinopathy (AMN)...

PURPOSE: To classify and characterize AMN lesions with SD-OCT during a follow-up as long as 5 years. METHODS: Retrospective study of 14 patients (18 eyes) with special focus on SD-OCT. We measured thickness of inner nuclear layer (INL), outer retinal layer (ONL), and hyperreflective band at baseline and during follow-up. AMN lesions were classified as type 1 and type 2. RESULTS: Of 14 patients (six males, eight females, mean age 29.7 years), three patients (four eyes) had type 1 and nine (12 eyes) had type 2...

PURPOSE: To describe the case of a born HIV seropositive woman who developed outer retinal alterations secondary to vascular abnormalities in the perimacular region and in the periphery of both eyes. METHODS: Case report. RESULTS: A 21-year-old woman born HIV seropositive was referred for a routinary visit. Her best-corrected visual acuity was 20/20 in both eyes, and during the visit, only mild superotemporal metamorphopsia in the left eye was reported...

Importance: Acute macular neuroretinopathy (AMN) is a rare, idiopathic condition resembling other acute maculopathies such as paracentral acute middle maculopathy. The pathophysiology of AMN is not well understood, and the role of the choroid in the pathogenesis of AMN remains controversial. Objective: To describe initial and serial multimodal imaging findings in AMN, with attention to choroidal vascular changes. Design, Setting, and Participants: Retrospective case series at a single institution, tertiary referral center...

Terson syndrome is defined as the incidence of intraocular hemorrhage in patients following a subarachnoid or intracranial bleed. A 38-year-old female with both intraretinal and subretinal hemorrhages secondary to Terson syndrome underwent repair of a ruptured cerebral aneurysm. One month following resolution of the macular hemorrhages, a paracentral scotoma persisted. Multimodal imaging (morphological and functional) confirmed the presence of acute macular neuroretinopathy Type 2 associated with deep retinal capillary ischemia...

PURPOSE: This is a case presentation of paracentral acute middle maculopathy in a 33-year-old white man with borderline hyperlipidemia. Paracentral acute middle maculopathy was originally thought to be a variant of acute macular neuroretinopathy; however, it is now generally accepted that these two conditions are separate disease entities. The etiology, evolution, and pathophysiology of acute macular neuroretinopathy and paracentral acute middle maculopathy are discussed, as well as current diagnostic techniques...

PURPOSE: Paraneoplastic retinopathy can be the first manifestation of systemic malignancy. A subset of paraneoplastic retinopathy is characterized by negative-type electroretinography (ERG) without fundus abnormality. Here we describe the multimodal imaging and clinico-pathological correlation of a unique case of acute progressive paravascular placoid neuroretinopathy with suspected retinal depolarizing bipolar cell dysfunction preceding the diagnosis of metastatic small cell carcinoma of the prostate...

A 32-year-old woman presented with the acute onset of a small scotoma in the right visual field. She was initially thought to have optic neuritis, but brain magnetic resonance imaging was normal. A review of her symptoms and medications disclosed recent use of oral contraceptives. Near-infrared imaging was the only objective abnormality, consistent with her Amsler grid changes, leading to the diagnosis of acute macular neuroretinopathy.

PURPOSE: To present en face optical coherence tomography (OCT) images generated by graph-search theory algorithm-based custom software and examine correlation with other imaging modalities. METHODS: En face OCT images derived from high density OCT volumetric scans of 3 healthy subjects and 4 patients using a custom algorithm (graph-search theory) and commercial software (Heidelberg Eye Explorer software (Heidelberg Engineering)) were compared and correlated with near infrared reflectance, fundus autofluorescence, adaptive optics flood-illumination ophthalmoscopy (AO-FIO) and microperimetry...
