Binocular Diplopia

Background: Diplopia is the double vision of a single object, and can be binocular or monocular. Binocular diplopia is caused by the misalignment of the visual axes, with images falling on the fovea of the fixating eye and on the extra-foveal retina of the non-fixating eye, as a consequence of both neurological (i.e., oculomotor nerve palsies, ocular myopathies, neuromuscular junction disorders) and ophthalmic disorders (i.e., decompensation of a pre-existing strabismus). In contrast, monocular diplopia is generally explained by intraocular pathology (i.e., refractive errors, ocular media abnormalities, dry eyes), causing the image of a single object to fall, at the same time, on the fovea and on the extra-foveal retina of the same eye. Methods: We report the case of a 22-year-old woman presenting with acute-onset monocular diplopia. Results: The diagnosis of idiopathic intracranial hypertension (IIH) was based on the presence of papilloedema and elevated cerebrospinal fluid (CSF) pressure. Monocular diplopia resolved after CSF subtraction. Conclusions: We describe a case of monocular diplopia as a presenting symptom of IIH, and discuss diagnostic issues of this possibly underestimated symptom in neurology clinical practice. Careful ophthalmic and neuro-ophthalmic examination can identify clinical features of diplopia, and drive diagnosis and treatment.

Introduction: The average incidence of perioperative stroke during major non-cardiac surgery is less than 1%, suggesting that it is rarely a major problem for the vast majority of patients. Methods: In our paper we present a 46-year-old patient undergoing acute right hemicolectomy who developed right-sided hemiparesis in the perioperative setting. Immediate CTAg examination showed an ischemic stroke in the left hemisphere as a result of left internal carotid thrombosis. A surgical procedure to recanalize the left carotid artery was performed 14 hours from the onset of neurological symptomatology and the neurological deficit gradually recovered fully. Conclusion: Our case report supports studies showing that a thorough diagnostic assessment allows the selection of patients who may benefit from urgent revascularization of acute internal carotid occlusion during the phase of acute brain ischemia.

The myelodysplastic syndrome-myeloproliferative neoplasms (MDS/MPNs) are defined by a group of heterogeneous hematological malignancies resulting from stem cell−driven clonal growth of pathological hematopoietic progenitors and ineffective hematopoiesis, they are characterized concomitant myelodysplastic and myeloproliferative signs. Myelodysplastic/myeloproliferative disorders have been considered to have a higher risk of thrombus formation.We report a rare case about a 64 years old Moroccan woman, experienced renal infarction (RI) associated with pulmonary embolism as a complication of a myelodysplastic/myeloproliferative disorder.The patient complained of acute-onset severe left flank pain, a contrast-enhanced computed tomography (CT) of the chest and abdomen revealed RI by a large wedge-shaped defect in the right kidney with pulmonary embolism.Biological exam showed deep anemia, the bone marrow aspiration found myelodysplasia.the bone biopsy showed signs of myeloproliferatif disease. The karyotype was normal, BCR-ABL, JAK2, CALR mutations were absents, and MPL mutation was positive. The International Prognostic Scoring System (IPSS-R) was 0, and the patient was included to the low risk group.Anticoagulation therapy was initiated with heparin to treat RI and pulmonary embolism. Three months later, pulmonary embolism had resolved without the appearance of additional peripheral infarction.This case emphasizes the need to consider myelodysplastic/myeloproliferative disorders as a cause of infraction renal and pulmonary embolism.
