Matthew G J Trese, Aristomenis Thanos, Yoshihiro Yonekawa, Sandeep Randhawa
The authors present the first case of paracentral acute middle maculopathy as a manifestation of primary antiphospholipid syndrome (APS) with multimodal imaging, including optical coherence tomography angiography (OCTA). The association between APS and ophthalmic sequela is well-known. Recent advances in multimodal imaging, specifically OCTA, allow for better characterization of the mechanism and extent by which retinal arterial thrombosis can cause vision loss. Using advanced imaging modalities, the authors provide a comprehensive assessment of retinal ischemia, which showed not only localized capillary occlusion, but also ischemia of the deep retinal capillary plexus...

The most common complication of coil embolization for cerebral aneurysms is thrombo-embolic stroke; in rare cases, these strokes, can present with central retinal artery occlusion. At our institution, a 53-year-old woman underwent stent-assisted coiling of the aneurysm. The patient's vision was improved immediately after intra-arterial thrombolysis and had further improved 8 months later. This report describes our experience of a rare case of central retinal artery occlusion after coil embolization that was successfully treated by intra-arterial thrombolysis...

PURPOSE: To compare stroke evaluations recommended by retina special-ists and neurologists for retinal artery occlusion (RAO). DESIGN: A cross-sectional survey. METHODS: An anonymous survey was emailed to members of the American Academy of Neurology Stroke Section listserv and vitreoretinal specialists registered with the American Academy of Ophthalmology. The survey was divided based on duration of symptoms before encounter: less than 12 hours, 24-48 hours, and more than 1 week...

PURPOSE: Optical coherence tomography (OCT) has become an important tool in the diagnosis and management of glaucoma; however, there can be overlap in the OCT findings between glaucoma and other diseases. We describe the clinical examination finings and interpretation of OCT imaging that led to the diagnosis of glaucoma masqueraders in a clinical case series. MATERIALS AND METHODS: Four adult patients seen in the glaucoma clinic at the Duke Eye Center were included in a retrospective observational case series...

REVIEW
Robert A Linsenmeier, Hao F Zhang
This article discusses retinal oxygenation and retinal metabolism by focusing on measurements made with two of the principal methods used to study O2 in the retina: measurements of PO2 with oxygen-sensitive microelectrodes in vivo in animals with a retinal circulation similar to that of humans, and oximetry, which can be used non-invasively in both animals and humans to measure O2 concentration in retinal vessels. Microelectrodes uniquely have high spatial resolution, allowing the mapping of PO2 in detail, and when combined with mathematical models of diffusion and consumption, they provide information about retinal metabolism...

BACKGROUND: Susac syndrome is characterised by the triad of encephalopathy with or without focal neurological signs, branch retinal artery occlusions and hearing loss. Establishment of the diagnosis is often delayed because the triad is complete only in a minority of patients at disease onset. This leads to a critical delay in the initiation of appropriate treatment. Our objective was to establish criteria for diagnosis of either definite or probable Susac syndrome. METHOD: The establishment of diagnostic criteria was based on the following three steps: (1) Definition of a reference group of 32 patients with an unambiguous diagnosis of Susac syndrome as assessed by all interdisciplinary experts of the European Susac Consortium (EuSaC) team (EuSaC cohort); (2) selection of diagnostic criteria, based on common clinical and paraclinical findings in the EuSaC cohort and on a review of the literature; and (3) validation of the proposed criteria in the previously published cohort of all Susac cases reported until 2012...

PURPOSE: Ischemic retinal damage can be reversed by hyperbaric oxygen therapy (HBOT) as long as irreversible infarction damage has not developed. However, the time window till irreversible damage develops is still unknown. The study aim was to evaluate the effect of HBOT and determine possible markers for irreversible retinal damage. MATERIALS AND METHODS: Retrospective analysis of 225 patients treated with HBOT for central retinal artery occlusion (CRAO) in 1999-2015...

Susac's Syndrome (SS) is a rare, autoimmune angiopathy characterized by hearing loss, retinal artery occlusions and encephalopathy, which is usually expressed in multifocal neurological signs and symptoms, confusion state and cognitive impairment. There have been few descriptions of neuropsychological assessment of SS. We present a case study of 29-year-old woman who developed full SS. During the post-acute stage of disease, she was admitted to neurorehabilitation ward to improve her cognitive-behavioral and motor functioning...

Retinal artery occlusion leads to profound visual impairment in the affected eye. It is rarely caused by local ophthalmic pathologies. Most patients present with a large number of cardio- and cerebrovascular risk factors. Visual loss is the leading symptom in central retinal artery occlusion (CRAO), whereas a circumscribed visual field defect is claimed in branch retinal artery occlusion (BRAO). Although many attempts have been made to improve the course of the disease, no effective therapy is available. There is some hope that intravenous fibrinolysis could influence the natural course but the therapeutic window is small (ca...

RATIONALE: Systemic lupus erythematosus (SLE) is a complex autoimmune disease characterized by autoantibody production, complement activation, and deposition of immune complexes in tissues and organs. SLE can involve any region of the visual system. Although ocular manifestations are not part of the classification criteria for SLE, they can be observed in up to one-third of the patients with SLE. They are rarely reported at the time of disease onset. Retinal vasculitis is usually associated with active generalized disease...

Background Although acute central retinal artery occlusion is as a stroke in the carotid territory (retinal artery), its management remains controversial. The aim of this study was to assess the feasibility and safety of intravenous thrombolysis delivered within 6 h of central retinal artery occlusion in French stroke units. Methods We performed a retrospective analysis of patients treated with intravenous alteplase (recombinant tissue-plasminogen activator), based on stroke units thrombolysis registers from June 2005 to June 2015, and we selected those who had acute central retinal artery occlusion...

BACKGROUND Central retinal artery occlusion (CRAO) is the occlusion of the central retinal artery resulting in retinal infarction and acute vision loss. Digital subtraction angiography (DSA)-guided superselective ophthalmic artery or selective carotid thrombolysis remains the preferred treatment method for CRAO. This study aimed to evaluate the safety and clinical efficacy of the novel ophthalmic artery branch retrograde thrombolytic intervention for CRAO. MATERIAL AND METHODS Fifty patients with monocular CRAO were enrolled, including 28 males and 22 females (mean age: 55...

The most serious complication of filler or fat injection is blindness. According to a recent systematic review of 98 patients of blindness provoked by filler or fat injection, only 2 patients had the outcome of a complete recovery of vision.In the literature, only 2 papers were found in which hyperbaric oxygen therapy (HBOT) was used in ophthalmic artery obstruction. However, no improvement of vision was obtained in either patient. Recently, the authors treated a patient who had central retinal vein occlusion and cilioretinal artery occlusion with HBOT (daily 2-hour sessions at 253 kPa for 14 days), and his visual acuity returned to normal...

PURPOSE: To determine the number of patients diagnosed over a 5-year period with isolated occlusion of the cilioretinal artery (CRAO) whilst pregnant, as well as to describe the outcomes and ophthalmological sequelae of this condition in pregnant woman. METHODS: A retrospective study of the medical records. RESULTS: From the 135 patients diagnosed with retinal arterial occlusion of all of our series, 20 (14.8%) had CRAO, and 2 (1.48%) of these were pregnant...
