BACKGROUND: To assess the prevalence of low corneal endothelial cell density and correlates of corneal endothelial cell density among adults attending Mbarara University and Referral Hospital Eye Centre in Uganda. METHODS: In this hospital-based cross-sectional study, participants 18 years and older, were enrolled. We obtained informed consent, and basic demographic data. We also conducted visual acuity, a detailed slit lamp examination, intra-ocular pressure, corneal diameter, tear-film break-up time, keratometry, A-scan, and pachymetry on all participants...

Type V hyperlipoproteinemia or multifactorial chylomicronemia syndrome is a rare lipid disorder triggered mainly by uncontrolled diabetes, obesity, poor diet, or particular medications. It is associated with an increased risk of acute pancreatitis and accelerated coronary artery disease which may manifest in younger age groups. We present a case of a 42-year-old male who presented to the emergency department (ED) complaining of a non-healing hand injury. Upon laboratory workup, the patient was found to have an elevated total cholesterol (TC) of 1129 mg/dL, very low levels of high-density lipoprotein (HDL) and triglycerides (TG) > 4000 mg/dL with an inability to calculate low-density lipoprotein (LDL)...

PURPOSE: To evaluate corneal densitometry (CD) of patients with arcus senilis (AS) and its association with the serum lipid markers. METHODS: This is a cross-sectional, case-control study. The AS diagnosis was made clinically. Forty-five eyes of 45 patients with AS and 38 eyes of 38 age-matched control subjects with no noticeable AS were enrolled in the study. All participants underwent detailed ophthalmologic examination along with corneal Scheimpflug imaging with CD measurement...

Background: Arcus Senilis (AS) appears as a white, grey or blue ring or arc in front of the periphery of the iris, and is a symptom of abnormally high cholesterol in patients under 50 years old. Objective: This work proposes a deep learning approach to automatic recognition of AS in eye images. Material and Methods: In this analytical study, a dataset of 191 eye images (130 normal, 61 with AS) was employed where ¾ of the data were used for training the proposed model and ¼ of the data were used for test, using a 4-fold cross-validation...

INTRODUCTION: The objective of this article is to describe the evolution of Schnyder dystrophy in 3 related patients of different ages and to highlight the discovery of a new mutation unidentified until now. CASE REPORT: We present a series of 3 cases, all first-degree relatives with no suggestion of consanguinity, of different ages (30, 40 and 59 years) and two distinct generations (mother and children). Slit lamp examination revealed the same lesions in our three patients: an early-onset corneal arcus senilis, central corneal deposits, and a gray stromal haze in the two oldest subjects...

BACKGROUND: Femtosecond laser-assisted cataract surgery (FLACS) has grown in popularity among ophthalmologists as a novel technique. However, descemet membrane detachment (DMD) began to be found as the complication after FLACS. We report a case of serious DMD following FLACS due to the inappropriate incision design. CASE PRESENTATION: An 85-year-old man with apparent cornea arcus senilis underwent femtosecond laser-assisted cataract surgery in his right eye. A biplanar model was chosen for the main incision...

The Hypertension Community has 3 conflicting dilemmas: a goal systolic pressure of 120 mm Hg or less (the SPRINT Trials), 40% of our 60,000,000 hypertensives still sustain blood pressures above 140/90 mm Hg, and our most potent antihypertensive drug minoxidil sits on the sidelines, imprisoned in the Food and Drug Administration's Black Box designation. My solutions to these dilemmas are: (1) review of the facts of our most potent antihypertensive drug minoxidil which is essentially free of toxicity, (2) treatment focus on the fundamental cause of high blood pressure, that is excess dietary sodium and, (3) prevention of, and/or reversal of, the fundamental mechanism of worsening hypertension, arteriolar hypertrophy...

PURPOSE: To compare the corneal biomechanical properties and intraocular pressure (IOP) levels in patients with and without arcus senilis (AS). METHODS: Ocular response analyzer measurements were performed on the right eyes of 37 patients with AS (group 1) and 37 control eyes (group 2). Corneal hysteresis, corneal resistance factor, Goldmann-correlated IOP, and corneal compensated IOP were recorded with Ocular response analyzer. Spherical equivalent value of the refractive errors, axial length, central corneal thickness, and IOP measured with Goldmann applanation tonometer were noted for each study eyes...

PURPOSE: To determine the prevalence of corneal arcus, its risk factors, and its relationship to ocular and visual indices. METHODS: In this cross-sectional study, 300 clusters were randomly selected from Shahroud in the north of Iran, using multistage sampling. A total of 20 people were invited to participate from each cluster. After enrollment, all optometric, biometric and ophthalmic exams were conducted on site. RESULTS: Of 6311 people invited, 5190 (82...

AIMS: Homozygous familial hypercholesterolaemia (HoFH) is a rare life-threatening condition characterized by markedly elevated circulating levels of low-density lipoprotein cholesterol (LDL-C) and accelerated, premature atherosclerotic cardiovascular disease (ACVD). Given recent insights into the heterogeneity of genetic defects and clinical phenotype of HoFH, and the availability of new therapeutic options, this Consensus Panel on Familial Hypercholesterolaemia of the European Atherosclerosis Society (EAS) critically reviewed available data with the aim of providing clinical guidance for the recognition and management of HoFH...

We developed a non-invasive device to quantify transparency (T), clear corneal diameter (CCD) excluding arcus senilis, and scleral rim diameter (SRD) of stored corneas. The T value (expressed in % on a relative scale), based on the modulation transfer function principle, referred to the ratio of local contrasts of a special LED backlit chart measured with and without cornea. CCD and SRD (in mm) were automatically calculated by morphologic operations. Firstly, we assessed measurement reproducibility. We then determined the agreement of T and CCD values with 3-level scores given independently by three experts on 179 scientific corneas...

We report the case of a 12-year-old male who developed corneal arcus and multiple skin lesions with a 10-year history of xanthomas. The lesions appeared over his fingers, hands, elbows, knees, buttocks and feet. Laboratory studies showed a total serum cholesterol level of 752.1 mg/dL; a triglyceride level of 96.6 mg/dL; a low-density lipoprotein cholesterol level of 661.3 mg/dL. Findings were consistent with homozygous familial hypercholesterolemia. To our knowledge, this is the first such case to be reported from China...

Familial hypercholesterolemia is a single gene disorder. It has autosomal dominant pattern of inheritance. We report a 28-year-old man who presented with acute myocardial infarction. He had xanthomas and an elevated serum low density lipoprotein cholesterol (LDL-C). His only sibling, 32-year-old brother have similar cutaneous lesions and lipid profile. His mother and maternal uncle died at a young age due to myocardial infarction. This report is to emphasize the need to clinically recognize xanthomas and its familial inheritance with elevated LDL-C, premature atherosclerosis...

PURPOSE: To report the first described cases of peripheral yellow corneal rings secondary to vitamin supplementation for age-related macular degeneration (ARMD). DESIGN: Retrospective single-center case series. PARTICIPANTS: The eyes of 4 patients taking vitamin supplementation for ARMD were examined at the University of Pittsburgh Medical Center Department of Ophthalmology between January 2010 and April 2011. METHODS: We reviewed the medical records of 4 patients with peripheral corneal rings receiving vitamin supplementation for ARMD...

Cornea plana is a rare disease in which the cornea is flattened with a low refractive power. In addition to these features, hypermetropia, deep central corneal opacities, hazy corneal limbus, peripheral scleralization of the cornea and early arcus senilis can also be seen. Closed-angle glaucoma may occur as a result of shallow anterior chamber and narrow angle; however, open-angle glaucoma has also been reported in these patients. Measuring the real intraocular pressure (IOP) value of such eyes is difficult since tonometers are affected by corneal curvature...

PURPOSE: To investigate the prevalence of corneal arcus and its associations. METHODS: The Central India Eye and Medical Study was a population-based study performed in rural Central India on 4711 subjects (age, 30+ years). Corneal arcus was assessed in corneal photographs. RESULTS: The study included 952 randomly selected participants. Mean body mass index (BMI) was 19.8 ± 3.6 kg/m(2), with 786 (41.3%) subjects being underweight (BMI < 18...

OBJECTIVE: To test the hypothesis that xanthelasmata and arcus corneae, individually and combined, predict risk of ischaemic vascular disease and death in the general population. DESIGN: Prospective population based cohort study. SETTING: The Copenhagen City Heart Study. PARTICIPANTS: 12,745 people aged 20-93 years free of ischaemic vascular disease at baseline and followed from 1976-8 until May 2009 with 100% complete follow-up...
