MuleG, Nardi E, Cottone S, Cusimano P, Volpe V, Piazza G, MongioviR, Mezzatesta G, Andronico G, Cerasola G (Universitadi Palermo, Palermo, Italy). Influence of metabolic syndrome on hypertension-related target organ damage. J Intern Med 2005; 257: 503-513. Objectives. The aim of our study was to analyse, in a wide group of essential hypertensive patients without diabetes mellitus, the influence of metabolic syndrome (MS) (defined according to the criteria laid down in the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults) on markers of preclinical cardiac, renal and retinal damage.

Incidence of Retinal Detachment in Germany: Results from the Gutenberg Health Study
2020
<b><i>Purpose:</i></b> To investigate the incidence of retinal detachment in the German population and to assess potential risk factors. <b><i>Methods:</i></b> The Gutenberg Health Study is a population-based cohort study in Mainz, Germany, including subjects (<i>n</i> = 15,010) with an age range from 35 to 74 years at baseline examination. Study participants underwent a comprehensive ophthalmological examination including distant-corrected visual acuity, refraction and slit-lamp examination at baseline examination. A computer-assisted telephone interview was conducted after 2.5 and 5 years, and health events were recorded. The 5-y…
Central retinal vein occlusion in young people.
1992
In a study performed on 20 subjects with central retinal vein occlusion (CRVO) aged 40 years or less we found the ischemic form in 20%. Disc edema was a common finding at the onset, while macular edema was less frequently seen. Systemic or ocular disorders that could be related with the development of the CRVO were often found; a patient was affected with myasthenia gravis and another with Sturge-Weber syndrome: these two diseases were not previously reported in association with CRVO. In only two of the 11 patients followed-up the visual acuity improved. The visual prognosis in CRVO of young people is often poor; the more frequent cause of the reduced visual acuity is chronic cystoid macula…
Bilateral maculopathy after exposure to a laser pointer: Optical coherence tomography angiography findings.
2018
Abstract Case report A 36-year-old man went to the emergency department the day after exposure to a laser pointer. Funduscopy revealed dispersed macular pigment alterations, and optical coherence tomography showed a disruption of the retinal layers. The visual acuity was counting fingers in both eyes. Nine months later, optical coherence tomography angiography showed a rarefaction in the choriocapillaris vascular flow in the area of the laser injuries. Discussion The retinal layer mainly damaged by the laser injury was the retinal pigment epithelium. However, it is suggested that the laser injury could involve tissues beyond the retinal pigment epithelium, since a rarefaction of the chorioc…
ACUTE VISION LOSS AS THE ONLY SIGN OF LEUKEMIA RELAPSE.
2016
Purpose To report a case of unilateral exudative retinal detachment as the sole presentation of relapsing B-type lymphoblastic leukemia in a 35-year-old man after 3 years of remission. Methods Case report. Results A 35-year-old man in complete remission of high-risk type B acute lymphoblastic leukemia (ALL-B) presented with acute vision loss in his left eye. Exudative retinal detachment was diagnosed at initial evaluation. Hematological and ocular studies were performed. Although there was no evidence of blood, cerebrospinal fluid, or bone marrow disease relapse, transvitreal retinochoroidal cytology identified the infiltration of lymphoblastic leukemic B cells with t(12:21) translocation a…
Microalbuminuria, renal dysfunction and cardiovascular complication in essential hypertension
1996
To evaluate the prevalence of microalbuminuria (albumin excretion rate, AER) in a wide hypertensive population, and to evaluate any relationship with cardiovascular damage and renal dysfunction.A transversal study.In 383 hospitalized Caucasian essential hypertensives (198 men, 185 women) of mean age 44 +/- 0.5 years and mean clinic blood pressure 170.3 +/- 0.95/ 103.4 +/- 0.47 mmHg, metabolic parameters, serum creatinine level (Cs), creatinine clearance rate (Ccs), 24 AER and plasma renin activity (PRA) were measured. Furthermore, each patient underwent 24 h ambulatory blood pressure monitoring (ABPM) and echocardiography to measure left ventricular mass, which was indexed both by body surf…
Cilioretinal artery occlusion.
2015
Background: The aim of this study was to evaluate characteristic findings and functional outcome of this rare type of retinal vascular occlusion in a large patient series. Patients and Methods: A retrospective chart review of all patients with a cilioretinal artery obstruction (CAO) seen at the University Eye Clinic Mainz (Germany) over a ten-year period between 1/1999 and 12/2008 was undertaken. The mean follow-up amounted to 42 months. Results: Thirty-three eyes were diagnosed with CAO. Three distinct groups were differentiated: (i) isolated CAO in 20/33 eyes; visual outcome achieving 20/50 in 17/20 eyes; (ii) CAO combined with central retinal vein occlusion in 9/33 eyes; visual outcome a…
Optical coherence tomography-based retinal vessel analysis for the evaluation of hypertensive vasculopathy
2013
Purpose Evaluation of retinal vessels in cardiovascular disease traditionally relies upon funduscopy, but more recently digital photo analysis has expanded the spectrum. As spectral domain optical coherence tomography (OCT) allows an in-vivo assessment of retinal tissue and its vessels on a histological scale, our study aimed at using this tool for the analysis of the retinal vasculature. Methods Circumferential peripapillary OCT scans (3DOCT-2000; Topcon Inc., Tokyo, Japan), with centration on the optic nerve head, were taken from 20 eyes (20 participants) with normal blood pressure and 20 eyes (20 participants) with arterial hypertension above 120 mmHg (mean blood pressure). The diameter …
Optical coherence tomography of chorioretinal and choroidal folds
2007
. Purpose: To report the optical coherence tomography (OCT) findings in cases of chorioretinal and choroidal folds. Methods: Eight subjects with folds of the fundus of the eye were examined with fundus photography, fluorescein angiography, B-scan ultrasonography and Stratus OCT. Results: Two types patterns were found on OCT. Five cases showed undulating retinal as well as retinal pigment epithelial lines of normal thickness; these were defined as chorioretinal folds. The posterior vitreous surface often adhered to the crests of the folds only. Three cases exhibited a wavy appearance of the retinal pigment epithelium and a flat retinal surface; these were classified as choroidal folds. Co…
Congenital neutropenia with retinopathy, a new phenotype without intellectual deficiency or obesity secondary toVPS13Bmutations
2013
Over one hundred VPS13B mutations are reported in Cohen syndrome (CS). Most cases exhibit a homogeneous phenotype that includes intellectual deficiency (ID), microcephaly, facial dysmorphism, slender extremities, truncal obesity, progressive chorioretinal dystrophy, and neutropenia. We report on a patient carrying two VPS13B splicing mutations with an atypical phenotype that included microcephaly, retinopathy, and congenital neutropenia, but neither obesity nor ID. RNA analysis of the IVS34+2T_+3AinsT mutation did not reveal any abnormal splice fragments but mRNA quantification showed a significant decrease in VPS13B expression. RNA sequencing analysis up- and downstream from the IVS57+2T>C…
