Department of Neurology, Pusan National University Hospital, Pusan National University School of Medicine and Medical Research Institute, Republic of Korea. A 25-year-old man developed prolonged loss of vision in the left eye. Examination revealed that visual acuity was 20/20 in the right eye and 10/20 in the left eye, with a left relative afferent pupillary defect. Fundoscopy showed multiple cotton wool spots in the left whole retina with normal optic disc. Fluorescein angiography (FA) revealed markedly delayed arterial, venous and recirculation time in the left eye without retinal arterial or venous occlusion. Bone marrow aspirate confirmed polycythemia vera. After the patient underwent phlebotomy, his visual acuity markedly improved and cotton wool spots in the retina disappeared. On follow-up FA, delayed arterial and venous filling, and recirculation time also became normalized. This case suggests that ischemic damage of the retina due to the great viscosity of blood may be a possible mechanism of monocular visual loss in polycythemia vera. Clinicians should be aware that isolated monocular visual loss may be an initial manifestation of polycythemia vera, since if untreated, polycythemia vera carries a high risk of permanent complications due to intravascular thrombosis.

Department of Neurology, University of Saskatchewan, Saskatoon, SK, Canada. Optic neuritis is a common cause of visual loss in young patients, typically presenting with painful monocular visual loss and decreased color vision. Visual function generally spontaneously improves over weeks, and 95% of patients return to visual acuity of at least 20/40 within 12 months. The initial magnetic resonance imaging (MRI) helps stratify the risk of multiple sclerosis (MS) in patients with acute isolated optic neuritis. In the Optic Neuritis Treatment Trial, the 10- year risk of MS in the group of patients with at least one MRI T2 lesion was 56%, whereas the 10-year risk with a normal baseline MRI was 22%. A normal MRI in concert with painless optic neuritis, severe optic nerve head edema, peripapillary hemorrhages, or a macular star defines a very low MS risk subgroup. High-dose steroids hasten the rate, but not the final extent, of visual recovery in optic neuritis, and the decision to use this therapy is individualized. Interferon beta-1a therapy should be considered in selected high-risk patients. PMID: 16819420 [PubMed - in process] Who loves ya.

Links Transient monocular visual loss patterns and associated vascular abnormalities.Bruno A, Corbett JJ, Biller J, Adams HP Jr, Qualls C. Neurology Service, Veterans Administration Medical Center, Albuquerque, NM 87108. To determine if certain transient monocular visual loss patterns predict the associated vascular abnormalities, we prospectively evaluated 100 consecutive patients. Each patient had hematologic tests, a carotid artery study (arteriography in 74, duplex ultrasonography in the remaining 26), and an ophthalmologic examination. Patients with altitudinal or lateralized transient monocular visual loss were more likely to have carotid artery stenosis, carotid artery ulceration, cardiac sources of emboli, or visible retinal emboli than patients with other visual loss patterns. Our findings suggest that altitudinal or lateralized transient monocular visual loss is primarily caused by embolism but that other visual loss patterns are usually caused by nonembolic mechanisms.

Links [Recovery of sickle cell disease ischemic maculopathy after erythropheresis: a clinical case study.][Article in French] Leveziel N, Kirsch O, Lautier-Frau M, Driss F, Offret H, Labetoulle M. Service d'Ophtalmologie, CHU du Kremlin-Bicetre, Le Kremlin-Bicetre, Paris. The authors report a case of a young patient with a recent decrease in unilateral vision. He had homozygote sickle cell disease with multiple general complications. Fundus examination was normal apart from a mild alteration of the macular reflect in the left eye, but fluorescein angiography showed multiple arteriolar macular occlusions, explaining the decrease in vision in the left eye. After erythropheresis, vision acuity improved and fluorescein angiography showed reperfusion. This case suggests that transfusional exchange may improve acute macular ischemia secondary to sickle cell disease. PMID: 16141931 [PubMed - indexed for MEDLINE] Who loves ya.
