Spotlight on fundus autofluorescence.
2018
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 the usefulness of FAF imaging in the noninvasive assessment and monitoring of retinal diseases, such as age-related macular degeneration, diabetic retinopathy, diabetic macular edema, central serous chorioretinopthy, retinitis pigmentosa and retinal dystrophies, are discussed in this rev…
Eclectic Ocular Comorbidities and Systemic Diseases with Eye Involvement: A Review.
2016
Coexistence of several ocular diseases is more frequent than suspected. In spite of the refractive errors, one or more of the following can be detected simultaneously: glaucoma, cataracts, uveitis, age-related macular degeneration, and dry eyes. In addition, as people age, ocular comorbidities are much more usually seen. Specific diseases are openly acknowledged to affect the eyes and vision, such as diabetes mellitus, hypertension blood pressure, arthritis, hyperthyroidism, neurodegenerative disorders, hematologic malignancies, and/or systemic infections. Recent advances in early diagnosis and therapy of the ophthalmic pathologies have reinforced patient options to prevent visual impairmen…
Proteomics in ocular fluids
2007
The focus of this article is to review recent techniques in proteomic analysis of ocular fluids. These fluids include tears, aqueous humor, and vitreous, they will also be compared to serum analysis. Furthermore, we attempt to summarize some disease correlated biomarkers in ocular fluids that were discovered through different proteomic techniques in eye diseases like dry eye, glaucoma, age-related macular degeneration, uveitis, or diabetic retinopathy. This review is trying to point out the importance of these biomarkers for clinical applications.
Transpupillary thermotherapy (TTT) for age-related macular degeneration (AMD) – Is it time to say good-bye?
2010
Abstract Purpose To evaluate the effectiveness of transpupillary thermotherapy (TTT) for the closure of classic and occult subfoveal choroidal neovascularization (CNV) and to discuss whether TTT is a useful treatment modality for age-related macular degeneration (AMD). Materials and methods The present paper is a retrospective review of the clinical results from a patient group which was treated with TTT in the University Eye Clinic in Mainz. From January 2000 to December 2002, a total of 20 eyes of 20 patients with subfoveal CNV (due to AMD in 16 eyes, due to pathologic myopia in 4 eyes) received TTT. The procedure was delivered using an infrared diode laser at 810 nm, equipped with a modi…
Smoking and age-related macular degeneration: review and update.
2013
Age-related macular degeneration (AMD) is one of the main socioeconomical health issues worldwide. AMD has a multifactorial etiology with a variety of risk factors. Smoking is the most important modifiable risk factor for AMD development and progression. The present review summarizes the epidemiological studies evaluating the association between smoking and AMD, the mechanisms through which smoking induces damage to the chorioretinal tissues, and the relevance of advising patients to quit smoking for their visual health.
Clinical Features and Natural History of AMD on OCT
2009
Despite recent progress, age-related macular degeneration (AMD) remains the leading cause of vision loss in high-income countries, and its incidence appears to be increasing, probably due to longer life span and improved methods of detection.
Towards the new spectral-domain optical coherence tomography based classification of age-related macular degeneration
2012
Abstract Introduction Age-related macular degeneration (AMD) is major social and health problem in industrialised societies. The contribution of the new diagnostic techniques, mainly spectral-domain optical coherence tomography (SD-OCT), has led to a better understanding of this disease. Aim To review the current clinical classification of AMD, to describe the new tomographic classification of wet AMD, and to review the new topographical findings in dry AMD. Development There are two classically described forms of AMD: dry and wet; there are also three progressive stages of severity: early, intermediate and advanced. This purely clinical stratification does not take into account any criteri…
Maintenance of anticoagulant and antiplatelet agents for patients undergoing vitreoretinal surgery
2010
International audience; Purpose: To establish the prevalence of anticoagulant, aspirin, and clopidogrel use in patients undergoing vitreoretinal surgery, and to compare the outcome of peribulbar anesthesia between users and non‐users. Methods: We conducted a retrospective case series in one academic center between January and June 2009. We analyzed the chart of 239 eyes who underwent posterior segment surgery with peribulbar anesthesia. No changes in the anticoagulant regimen were made prior to surgery. We divided patients into 7 groups: group 1: patients with no anticoagulants and 6 groups defined according to the type of anticoagulant or antiplatelet medication. Results: 239 eyes (206 pat…
Retina Summit Karlsruhe 2009
2009
During the this year´s Retina Summit Karlsruhe, an international expert faculty of 20 highly renowned retina specialists and more than 300 participants found their way to Karlsruhe to share their knowledge of the latest trends in surgical technology and pharmacology. After an angiography course on Friday, the 1-day symposium of almost 40 short lectures covered recent developments in age-related macular degeneration and diabetic macular edema, and the implications and challenges associated with microincision vitrectomy surgery, new devices and advances in imaging technologies.
Cholesterol and ocular pathologies: focus on the role of cholesterol-24S-hydroxylase in cholesterol homeostasis
2015
The retina is responsible for coding the light stimulus into a nervous signal that is transferred to the brain via the optic nerve. The retina is formed by the association of the neurosensory retina and the retinal pigment epithelium that is supported by Bruch’s membrane. Both the physical and metabolic associations between these partners are crucial for the functioning of the retina, by means of nutrient intake and removal of the cell and metabolic debris from the retina. Dysequilibrium are involved in the aging processes and pathologies such as age-related macular degeneration, the leading cause of visual loss after the age of 50 years inWestern countries. The retina is composed of severa…
