Autofluorescence imaging of pingueculae

British Journal of Ophthalmology, 2008
To analyse the autofluoresence (AF) properties of pingueculae and compare the size of AF with the extent of the visible lesion.Forty eyes of 23 patients with pingueculae were included in the study. AF images were obtained using an HRA2 confocal scanning laser ophthalmoscope; anterior segment photographies were obtained using TRC-50IX, IMAGEnet 2000 ...

Autofluorescence of living cells

Journal of Microscopy, 1998
We have investigated the autofluorescence of viable mammalian cells (DU‐145 and V79) with a confocal laser scanning microscope equipped with a UV laser. Our aim was to investigate the autofluorescence dependence on different treatments in mitochondria and lysosomes by using different reagents and to improve the confocal laser scanning microscope image ...

Autofluorescence of treated retinoblastoma

Journal of American Association for Pediatric Ophthalmology and Strabismus, 2011
To describe the autofluorescent features of retinoblastomas after treatment.Standard fundus photography and autofluorescence (AF) photography (580 nm excitation, 695 nm barrier filter) were performed on 88 tumors of 61 patients. Clinical features were correlated with autofluorescent features.The mean patient age at AF was 10.3 years.

Autofluorescence Endoscopy

Gastrointestinal Endoscopy Clinics of North America, 2009
Autofluorescence endoscopy is a wide area imaging technique, with the ability to rapidly examine a large surface area of gastrointestinal mucosa to detect small areas of dysplasia or cancer. It has potential in diseases such as Barrett's esophagus, ulcerative colitis, and gastric cancer, in which large areas of mucosa may harbor areas of dysplasia or ...

Autofluorescence of Visual Receptors

Nature, 1969
SINCE 1878 when Kuhne reported the faint bluish fluorescence of the dark adapted retina and its brighter greenish supplementation when the visual pigments were bleached1, these observations have been little used or extended2,3. Early in 1966, during another investigation, one of us noticed the interesting microscopic autofluorescence pattern shown in ...

Fundus Autofluorescence

Fundus autofluorescence (FAF) imaging is a noninvasive and rapid technique to visualize fluorophores in the fundus. The physical principle is based on the excitation of certain molecules by a specific wavelength of light and emission through a longer wavelength.

Diagnostic Techniques: Autofluorescence

2013
Autofluorescence is a relatively new, noninvasive diagnostic tool recently introduced in the armamentarium of intraocular tumor diagnosis and characterization. This technique may reveal the effects of choroidal tumors on the overlying retinal pigment epithelium and may also provide specific information on intrinsic pigments that compose and ...

AUTOFLUORESCENCE OF CHOROIDAL MELANOMAS

RETINAL Cases & Brief Reports, 2007
To report autofluorescence findings for two patients with choroidal melanomas.Records and photographs for two patients with choroidal melanomas were reviewed. Fundus autofluorescence photography was performed using the Heidelberg confocal SLO system (Heidelberg Retina Angiograph; Heidelberg Engineering, Dossenheim, Germany).Both patients had lipofuscin

Panoramic Autofluorescence

Optometry and Vision Science, 2012
ABSTRACT Purpose. Recent technological advances in fundus autofluorescence (FAF) are providing new opportunities for insight into retinal physiology and pathophysiology. FAF provides distinctly different imaging information than standard photography or color separation.
