Cigarette smoke is a complex chemical mixture, involving health-damaging components such as carbon monoxide, ammonia, pyridine, toluene and nicotine. While cognitive functions have been well documented in heavy smokers, spatial vision has been less characterized. In the article, we investigated smoking effects through contrast sensitivity function (CSF), a rigorous procedure that measures the spatial vision. Data were recorded from 48 participants, a group of non-smokers (n = 16), a group of chronic and heavy cigarette smokers (n = 16) and deprived smokers (n = 16); age range 20-45 years...

Bhandari, Sanjeeb Sudarshan, Pranawa Koirala, Nirajan Regmi, and Sushil Pant. Retinal hemorrhage in a high-altitude aid post volunteer doctor: a case report. High Alt Med Biol 00:000-000, 2017.-High-altitude retinal hemorrhages (HARHs) are seen at altitudes more than 3000 m, are usually multiple, flame shaped, and adjacent to blood vessels. Development near the macula causes blurring of vision, otherwise, they are symptomless and self-limiting. They often develop during the first few days after ascent to high altitude and subjects often suffer from acute mountain sickness (AMS) or high-altitude cerebral edema (HACE)...

OBJECTIVES: The primary role of magnetic resonance imaging (MRI) in a patient with suspected optic neuropathy is to rule out nonischemic disorders, and many of the reported cases of ischemic optic neuropathy with positive neuroimaging are atypical forms of ischemic optic neuropathy. We studied the role of diffusion-weighted images of MRI in patients with ocular ischemia. METHODS: We describe the clinical, fundoscopic and neuroimaging characteristics of 3 patients with definite ocular ischemia related to occlusion of the carotid artery...

A 55-year-old man was admitted to our hospital for investigation of high fever, decreased consciousness and bilateral visual impairment. His cerebrospinal fluid analysis revealed pleocytosis of mononuclear cells and an increased protein concentration. FLAIR images revealed multiple high-intensity lesions in the frontal lobe, part of which was enhanced with gadolinium. Despite initiating treatment with acyclovir and corticosteroids, his consciousness and visual acuity deteriorated. Immunopathological examination of brain biopsies showed numerous herpes simplex virus type 2-positive neurons and macrophages, leading to a diagnosis of herpes simplex encephalitis (HSE)...

BACKGROUND: Human toxocariasis, caused by Toxocara canis, T. cati, and T. vitulorum of dogs, cats and ruminants respectively, is recognized as an important zoonotic infection worldwide. The typical clinical syndromes of toxocariasis in humans are ocular larva migrans (OLM) and visceral larva migrans (VLM). The most commonly affected sites of OLM are the peripheral retina and/or vitreous humor. In Sri Lanka, there is a dearth of information on prevalence of ocular infection in our population...

Background: The fundoscopic examination of hypertensive patients, which is an established hypertension-related target organ damage (TOD), tends to be underutilized in clinical practice. We sought to investigate the relationship between retinal alterations and left atrium (LA) volumes by means of real-time, three-dimensional echocardiography (RT3DE), which is the most pivotal predictor of diastolic dysfunction. Methods: Our population consisted of 88 consecutive essential hypertensive patients (age 59...

INTRODUCTION: Neurosyphilis is an infection of the central nervous system by Treponema pallidum, which can occur after the initial syphilis infection. Although commonly associated with late stage disease, patients with early neurosyphilis may present with acute syphilitic meningitis, meningovascular syphilis, or uveitis. CASE: A 28 year old man with a past medical history of HIV (CD4 364);, and recent diagnosis of uveitis presented to the Emergency Department with a positive RPR result...

A retrospective case control study was conducted in the Peking Union Medical College Hospital. Medical records were reviewed for demographic data, clinical features, laboratory results, systemic lupus erythematosus (SLE) disease activity evaluations, and ophthalmic examinations to investigate the clinical characteristics and significance of retinal vasculopathy (RV) in Chinese patients with systemic lupus erythematosus. The prevalence of RV was approximately 0.66% (35/5298) in SLE patients. A total of 60 eyes were involved...

PURPOSE: To report a case of IgG4-related ophthalmic disease (IgG4-ROD) which presented as choroidal and orbital lesions. METHODS: Case report. RESULTS: A 64-year-old man presented with left eye photopsias and a history of IgG4-related perirenal fibrosis. Fundoscopic examination showed multiple bilateral yellow choroidal lesions, and optical coherence tomography showed multiple choroidal lesions. Magnetic resonance imaging of the orbits showed an enhancing lesion present circumferential to the optic nerve, but greater medially, abutting the posterior surface of the left globe...

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...

INTRODUCTION: The combination of bilateral microphthalmos, cystic coloboma and eyelid agenesis is rare. The definite diagnosis of this malformation is established by fundoscopic examination and confirmed by imaging modalities such as ultrasonography (US) and magnetic resonance imaging (MRI). This disorder may be associated with specific chromosomal abnormalities. CASE REPORT: A 1-week-old male newborn was referred for bilateral eyelid agenesis. He was born at term by caesarean for foetal distress, after an uneventful gestation...

BACKGROUND: Data on ocular manifestations of inflammatory bowel disease (IBD) in children are limited. Some authors have reported a high prevalence of asymptomatic uveitis, yet the significance of these observations is unknown and there are no recommendations on which ophthalmologic follow-up should be offered. METHODS: Children with IBD seen at a single referral center for pediatric gastroenterology were offered ophthalmologic evaluation as part of routine care for their disease...

BACKGROUND: The ocular fundus examination is infrequently and poorly performed in the emergency department (ED) clinical settings, placing patients at risk for missed diagnosis of hypertensive emergencies. The aim of this study was to investigate the feasibility of the ocular fundus photography with a smartphone small optical device in an ED setting and to compare it with a traditional ocular fundus examination. METHODS: The study included 52 consecutive patients (mean age 69 ± 16 years, 50% women) presenting to a hospital ED with an acute increase in blood pressure (SBP > 180 and/or DBP > 100 mmHg)...

INTRODUCTION: Retinopathy is a chronic complication with severe functional consequences in patients with sickle cell disease. Its prevalence is not well known in sub-Saharan Africa because of the absence of screening. We report here the results of a routine screening for sickle retinopathy in a Comprehensive Sickle Cell Center in Sub-Saharan Africa. METHODS: Screening of sickle retinopathy was carried out in all sickle cell patients aged 10 and over, followed between 2010 and 2012...

BACKGROUND AND OBJECTIVE: To describe the ocular toxicity of intravitreal carboplatin and etoposide phosphate (VP16P) in Dutch-Belted rabbits. MATERIALS AND METHODS: Twenty-two adult male Dutch-Belted rabbits (Cohort 1) each received a single, bilateral intravitreal injection (0.05 mL). For Cohort 1, safety was assessed via electroretinograms (ERGs) and ocular examination. Of nine total groups in Cohort 1, the first five received the following single agents: Group 1: normal saline; Group 2: VP16P 75 µg; Group 3: VP16P 100 µg; Group 4: carboplatin 4 µg; and Group 5: carboplatin 8 µg...

BACKGROUND: To analyze the most common neurophthalmological conditions that may mimic glaucomatous optic neuropathy and to determine which most often lead to misdiagnosis when evaluated by a glaucoma specialist. METHODS: We reviewed the charts of consecutive patients with optic neuropathies caused by neurophthalmological conditions screened in a single Eye Clinic within a period of 24 months. Within these enrolled patients, we selected the eyes whose fundoscopic appearance could resemble glaucoma based in pre-defined criteria (vertical cup-to-disc ratio ≥0...
