Spotlight on fundus autofluorescence

2018

Ana M Calvo-Maroto,1 Alejandro Cerviño2 1Department of Ophthalmology, Clínica Universidad de Navarra, University of Navarra, Madrid, Spain; 2Optometry Research Group, Department of Optics and Optometry and Vision Sciences, University of Valencia, Valencia, Spain Abstract: Fundus autofluorescence (FAF) imaging is based on the fluorescence from ocular endogenous fluorophores located in the retinal pigment epithelium and choroid, mainly lipofuscin and melanin. It is a noninvasive technique that provides information about the spatial distribution of lipofuscin/melanin and retinal pigment epithelium health status. An overview about the fluorophores responsible for FAF imaging and t…

Prevalence of visual impairment and refractive errors in an urban area of Mexico

2019

AIM: To determine the distribution of refractive errors in a school-age population in Quintana Roo (Mexico) in the framework of an international cooperation campaign for the prevention of blindness. METHODS: A sample of 2647 school-age children (ranging from 5 to 14 years old) with a mean age of 9.1±1.9 years old were tested by trained volunteers for distance visual acuity (VA) and refractive errors. The first screening examination included uncorrected distance visual acuity (UDVA) and VA with a +2.00 D lens. Inclusion criteria for a second complete cycloplegic eye examination performed by an optometrist were UDVA <20/25 (0.10 logMAR or 0.8 decimal) and/or VA with +2.00 D ≥20/25. RESULTS: A…

Russia and the olympic movement : a study of Russian national identity as described in the newspaper Sovetskij Sport during the winter olympic games …

2010

The topic of the thesis deals with Russia and the Olympic Movement, studying Russian national identity as it is described in the newspaper Sovetskij Sport during three past Winter Olympic Games (1988, 1992, 1994) and the upcoming Winter Olympic Games that take place in Sochi 2014 in the framework of international politics. The research task is to analyze, what kinds of discourses do the writings of Russian Olympic Committee’s leading sports journal Sovetskij Sport use in times of the above mentioned Olympic Games in relation to the “West”. It is studied, in which way can these discourses be understood as representations of national identity in the framework of political upheavals. Politics …

Retinal Straylight Before and After Penetrating Keratoplasty in an Eye with a Post-Herpetic Corneal Scar

2008

Objetivo: Estudio in vivo de la luz dispersa que alcanza la retina en un paciente antes y despues de someterse a una queratoplastia penetrante (o sus siglas en ingles, PKP). Metodos: En un paciente varon de 65 anos con una ulcera corneal herpetica se midio la proporcion de luz dispersa que alcanza la retina tanto antes como despues de una PKP, utilizando para ello un metodo psicometrico denominado "de comparacion por compensacion" («Compensation comparison method», C-Quant straylightmeter, Oculus GmbH, Alemania). Resultados: La cantidad de luz dispersa que alcanza la retina medida antes de la cirugia fue elevada en comparacion con los valores obtenidos en estudios previos en sujetos normale…

Proteome alterations in aqueous humour of primary open angle glaucoma patients.

2019

Aim To unravel the primary open angle glaucoma (POAG) related proteomic changes in aqueous humour (AH). Methods Totally 35 patients listed for cataract surgery (controls: n=12, age: 67.4±13.6y) or trabeculectomy for POAG (n=23, age: 72.5±8.3y) were included. AH samples of those patients were obtained during cataract surgery or trabeculectomy. AH samples were subsequently pooled into the experimental groups under equal contribution in terms of protein amount of each individual patient. Protein samples were analyzed by a linear trap quadrupol Orbitrap Mass Spectrometry device with an upstream liquid chromatography system. The obtained raw data were analyzed using the Maxquant proteome softwar…

Decreased Perifoveal Sensitivity Detected by Microperimetry in Patients Using Hydroxychloroquine and without Visual Field and Fundoscopic Anomalies

2015

Purpose. To evaluate the usefulness of microperimetry in the early detection of the ocular anomalies associated with the use of hydroxychloroquine.Methods. Prospective comparative case series study comprising 14 healthy eyes of 7 patients (group A) and 14 eyes of 7 patients under treatment with hydroxychloroquine for the treatment of rheumatologic diseases and without fundoscopic or perimetric anomalies (group B). A comprehensive ophthalmological examination including microperimetry (MP) and spectral-domain optical coherence tomography was performed in both groups.Results. No significant differences were found in mean MP foveal sensitivity between groupsP=0.18. However, mean MP overall sens…

Pilot Study on Visual Function and Fundus Autofluorescence Assessment in Diabetic Patients.

2015

Purpose. Evaluate optimized fundus autofluorescence (FAF) imaging in early stages of diabetic retinopathy (DR) and relate findings with conventional colour fundus imaging and visual function in diabetic patients and control subjects.Materials and Methods. FAF and colour images were obtained using the CR-2 Plus digital nonmydriatic retinal camera in seven diabetic patients and thirteen control subjects. Visual-Functioning Questionnaire-25 (VFQ-25) and Diabetes Self-Management Questionnaire (DSMQ) were used to assess the quality of life and diabetes self-care. Contrast sensitivity function (CSF) was evaluated with the Vistech 6500 chart.Results. FAF and optimized-FAF imaging showed more retin…

Rapid Regression of Exudative Maculopathy in Idiopathic Retinitis, Vasculitis, Aneurysms and Neuroretinitis Syndrome after Intravitreal Ranibizumab

2012

The idiopathic retinitis, vasculitis, aneurysms and neuroretinitis syndrome is a rare retinal vascular disorder characterized by multiple leaking aneurysmal dilations, retinal vasculitis, neuroretinitis and peripheral vascular ischemia. Visual loss mainly occurs due to the development of retinal neovascularization and/or exudative maculopathy. Although the treatment of choice has not yet been established, retinal photocoagulation seems to be the best option to control the disease and to prevent its progression. Herein, we report a case of idiopathic retinitis, vasculitis, aneurysms and neuroretinitis syndrome with both retinal neovascularization and macular exudation successfully managed wi…
