Kumar Naren Chandra, Meghraj Kundan
Postoperative visual loss is a rare and devastating complication. The estimated incidence is 0.01-1% after non ocular surgery. It has been reported after spine, cardiac and head and neck surgeries. We report a patient who was operated for cervical laminectomy in prone position and complained of loss of vision in one eye postoperatively. He was thoroughly investigated after visual loss. The case was diagnosed as central retinal artery occlusion (CRAO) of the left eye. Here we consider the potential etiological factors causing this unilateral loss of vision and try to suggest strategies to reduce the incidence of the complication in spinal surgery...

Objective: To report a case of iatrogenic central retinal artery occlusion after embolization and surgical resection of carotid body paraganglioma. Methods: Case report Results: One adult female patient presented with persistent unilateral visual loss after embolization with Embosphere(®) and Contour(®) microparticles of carotid body tumor. Fluorescein angiography revealed intraluminal microspheres in the central retinal artery ramifications. OCT revealed intraretinal spherical, hyporeflective particles with posterior shadowing...

Takayasu arteritis (TA) is a systemic vasculitis of unknown etiology that affects the aorta and its primary branches or large arteries in the proximal upper or lower extremities. Ocular manifestations of TA include microaneurysm formation, small-vessel dilation, arteriovenous anastomosis, retinal ischemia, and neovascular glaucoma. We herein report a case involving a 23-year-old Asian woman who presented with isolated acute anterior ischemic optic neuropathy and was initially misdiagnosed with optic neuritis...

PURPOSE: We report on a case of Acanthamoeba keratitis (AK)-related reactive ischemic posterior segment inflammation following intraocular surgery in a patient with primary Sjögren's syndrome (PSS). CASE REPORT: A 48-year-old female patient with severe protracted AK underwent uneventful cataract surgery upon development of a corneal scar. Four weeks postoperatively, she experienced a rapid loss of vision to no light perception. Central retinal artery occlusion and ischemic optic neuropathy could be excluded, and a diagnosis of PSS was made...

BACKGROUND AND PURPOSE: We aimed to determine the incidence of co-occurring cerebral ischemia, extent of cerebral small vessel disease, and vascular risk profile of patients with acute retinal ischemia. METHODS: RETIS (Frequency of Acute Silent Brain Infarction and Systematic Evaluation of Stroke Risk in Retinal Ischemia) was a single-center, prospective, observational study comprising ophthalmologic examination, brain magnetic resonance imaging, and extensive diagnostic work-up of vascular risk factors and stroke cause...

PURPOSE: To describe the technique of simultaneous keratolimbal autograft and penetrating autokeratoplasty to restore monocular vision of a blind patient with limbal stem cell deficiency (LSCD). METHODS: A patient with acquired monocular vision due to loss of the left eye owing to LSCD postblast injury presented with acute loss of vision in the right eye due to central retinal artery occlusion. Simultaneous keratolimbal autograft and penetrating autokeratoplasty were performed in attempt to restore his vision in the left eye...

PURPOSE: Retinal ischemia is a common feature shared by numerous eye diseases. Ischemic insult leads to retinal dysfunction and neuronal death. Lycium barbarum polysaccharides (LBP), extracts from an anti-aging and anti-oxidation Oriental medicine, are well known for eyesight preservation. We have previously reported the effect of LBP on cell death, blood ocular barrier and oxidative stress within 24 hours in a mouse model of retinal ischemia. This study focuses on retinal function and looks for ultrastructural and cellular correlates after a relatively long period of reperfusion for 7 days...

CASE REPORT: The case is presented of a young man with an atypical haemolytic-uraemic syndrome (aHUS), complicated with bilateral serous retinal detachment, cotton wool spots, and a branch artery occlusion. Treatment with plasmapheresis, haemodialysis and systemic eculizumab led to the blood and urine parameters returning to normal, as well as resolution of the retinal anomalies. Genetic analysis show both mutations in complement factor H and C3. DISCUSSION: Haemolytic-uraemic syndrome (HUS) is a thrombotic microangiopathy characterised by microangiopathic haemolytic anaemia, thrombocytopenia, and acute renal failure...

The neuropeptide pituitary adenylate cyclase activating polypeptide (PACAP) has two active forms, PACAP1-27 and PACAP1-38. Among the well-established actions are PACAP's neurotrophic and neuroprotective effects, which have also been proven in models of different retinopathies. The route of delivery is usually intravitreal in studies proving PACAP's retinoprotective effects. Recently, we have shown that PACAP1-27 delivered as eye drops in benzalkonium-chloride was able to cross the ocular barriers and exert retinoprotection in ischemia...

Background: Vision loss is a rare but serious complication of facial hyaluronic acid (HA) filler injection, for which there is no proven rescue therapy. Retrobulbar hyaluronidase injection is advocated by many plastic surgeons as an emergency treatment, but has not been carefully assessed for its efficacy. Objectives: To evaluate the efficacy of retrobulbar hyaluronidase injection as a rescue treatment for vision loss caused by HA filler embolization. Methods: Patients with vision loss caused by HA filler embolization were treated with retrobulbar hyaluronidase injection...

BACKGROUND: The effect of pancreas transplantation on diabetic retinopathy remains inconclusive. Herein, we report six patients with type 1 diabetes mellitus (DM) who underwent pancreas transplantation and developed acute macular edema and peripapillary soft exudate with rapid progression to proliferative diabetic retinopathy. METHODS: In this retrospective observational study, diabetic patients who underwent pancreas transplantation in a single medical center and developed symptomatic acute macular edema and peripapillary soft exudate within 3 months after the operation were enrolled...

A 32-year-old woman experienced dizziness and headache for 5 months. She also complained of painless, progressive bilateral visual loss for several weeks. Before developing the initial symptoms, she had an uncomplicated pregnancy except for dizziness and systemic hypotension during the first term. Fundus examination disclosed prominent retinal arteries as well diffuse microaneurysms, widespread intraretinal hemorrhages, and hyperemic optic disks. Brain magnetic resonance imaging revealed multiple supratentorial white-matter lesions suggestive of ischemic strokes...

A 44-year-old male patient presented with features suggestive of transient central retinal artery occlusion (CRAO) followed by permanent CRAO and lateral posterior ciliary artery occlusion. He had diagnostic features of polycythemia vera (PV). When presented for the first time, the patient had features of ocular ischemia such as ocular pain, conjunctival congestion, and retinal opacification but with normal arm-to-retina time and normal arteriovenous transit time. During the second presentation, he had ocular pain, congested conjunctiva, retinal opacification, cherry red spot with box-carrying of retinal vessels, and choroidal infarct (Amalric's sign)...

PURPOSE: To report the youngest female carrier of Fabry disease, complicated by cilioretinal artery occlusion and anterior ischemic optic neuropathy (AION). METHODS: Case report. RESULTS: An 11-year-old girl was referred to our clinic with painless, acute loss of vision in her right eye. Posterior segment examination and fluorescein angiography revealed cilioretinal artery occlusion and AION. Systemic evaluations were unremarkable, except for a low blood α-galactosidase A enzyme level of 242...
