BACKGROUND: We report a rare case of optic neuropathy following dacryocystorhinostomy (DCR) in a 57-year-old female patient with May-Hegglin anomaly. CASE PRESENTATION: The patient was presented with sudden onset of vision loss for the left eye after DCR under general anesthesia. Her best corrected visual acuity was light perception in the left eye. Relative afferent pupillary defect was detected in her left eye. Magnetic resonance imaging of the orbit revealed an hyperintensity at the intra-orbital segment of the left optic nerve on T2-weighted image and Flair image. The patient was diagnosed with acute postoperative optic neuropathy and treated with methylprednisolone. Although her vision partially improved, she was left with a visual field defect in the left eye. CONCLUSIONS: In patients with hematologic diseases, postoperative vision loss can occur following even minor surgery under general anesthesia, such as DCR. Therefore, preoperative counseling regarding the risk of visual loss should be given to high-risk patients.
Acute retinal arterial ischemia, including vascular transient monocular vision loss (TMVL) and branch (BRAO) and central retinal arterial occlusions (CRAO), are ocular and systemic emergencies requiring immediate diagnosis and treatment. Guidelines recommend the combination of urgent brain magnetic resonance imaging with diffusion-weighted imaging, vascular imaging, and clinical assessment to identify TMVL, BRAO, and CRAO patients at highest risk for recurrent stroke, facilitating early preventi...

Purpose To reassess the prevalence and incidence of post–cataract surgery optic neuropathy (PCSON) in the modern era. Design Retrospective cohort study. Methods Setting: Single-center tertiary care practice. Study Population: All patients with a diagnosis of nonarteritic anterior ischemic optic neuropathy (NAION) seen in the Wilmer Eye Network system between January 1, 2010 and December 31, 2014 were included. Inclusion was based on the following: (1) a history of an acute unilateral decrease in...
Nosso objetivo e descrever a ocorrencia de neuropatia optica isquemica anterior nao-arteritica (NOIA-NA) apos vitrectomia posterior para tratamento do buraco macular. Uma mulher de 56 anos de idade previamente higida apresentou buraco macular de espessura total no olho direito (OD) e uma relacao escavacao disco pequena em ambos os olhos. No quinto dia de pos-operatorio ela notou uma perda visual subita e indolor OD associado a presenca de um defeito pupilar aferente relativo e pressao intraocula...

Background:Perioperative ischemic optic neuropathy (ION) causes visual loss in spinal fusion. Previous case–control studies are limited by study size and lack of a random sample. The purpose of this study was to study trends in ION incidence in spinal fusion and risk factors in a large nationwide ad

Abstract Background Context Perioperative visual loss (POVL) after spinal deformity surgery is an uncommon but severe complication. Data on the incidence and risk factors of this complication after corrective surgery in the pediatric population are limited. Purpose The present study aimed to investigate nationwide estimates of POVL after corrective surgery for pediatric scoliosis. Study Design This is a retrospective study that uses a nationwide database. Patient Sample The sample includes 42,33...

Purpose To describe the clinical characteristics of and risk factors for the development of optic neuropathy after pars plana vitrectomy (PPV) for macula-sparing primary rhegmatogenous retinal detachment (RRD) repair. Design Retrospective case-control study. Participants Seven patients who underwent PPV for macula-sparing primary RRD with subsequent development of optic neuropathy and 42 age- and gender-matched control patients undergoing PPV for macula-sparing primary RRD. Methods Retrospective...
Summary MYH9-related disease (MYH9-RD) is one of the most frequent forms of inherited thrombocytopenia. It is transmitted in an autosomal dominant fashion and derives from mutations of MYH9, the gene for the heavy chain of non-muscle myosin IIA. Patients present with congenital macrothrombocytopenia with mild bleeding tendency and may develop kidney dysfunction, deafness and cataracts later in life. The term MYH9-RD encompasses four autosomal-dominant thrombocytopenias that were previously descr...
Acute angle closure glaucoma is a rare complication of general anesthesia. However, in case of delayed diagnosis, it may lead to blindness. We present a case of bilateral acute angle closure glaucoma after cervical spine surgery under general anesthesia in a hypermetropic patient. In this case, the most likely trigger was the use of ephedrine, but nefopam administration and the prone surgical position are discussed as additional potential factors.
