Automated analysis of digital fundus autofluorescence images of geographic atrophy in advanced age-related macular degeneration using confocal scanning laser ophthalmoscopy cSLO. Several lines of evidence suggest that excessive lipofuscin accumulation represents a common downstream pathogenic pathway in various hereditary and complex retinal diseases. Sparrow JR, Boulton M. The Fluorescent Fundus What causes fundus autofluorescence? Page 14 – Identification and characterization of multiple forms of rhodopsin and minor proteins in frog and bovine rod outer segment disc membranes. Page 13 – The kDa rim protein of retinal rod outer segments is a member of the ABC transporter superfamily.

Retinal dystrophies and degenerations also show abnormal autofluorescence, said Dr.

Atlas of Fundus Autofluorescence Imaging – Google Books

Fundus autofluorescence and development of geographic atrophy in age-related macular degeneration. Finally, pathological alterations in the inner retina at the central macula where the FAF signal is usually partially masked by luteal pigment lutein and zeaxanthin may result in manifest variations in FAF intensities.

This patient with macular dystrophy shows a ring of increased autofluorescence in the parafovea which is not visible on fundus photography. Ophthalmic imaging by spectral optical coherence tomography.

J Biol Chem As with diseases that cause a imagint of vitelliform material, said Dr. Invest Ophthalmol Vis Sci ; We can thoroughly recommend this book to general ophthalmologists as well as retina specialists. Spaide, the extent of CSC is best seen with autofluorescence, not just in the area of the subretinal fluid but also in other parts of the macula or even the other eye.

However, FAF imaging shows widespread abnormalities in the fundus and also can find areas of atrophy within the lesions. Product details Format Paperback pages Dimensions x x The distinct, lace-like pattern is more evident in the FAF-image. In patients with retinitis pigmentosa and cone dystrophies, parafoveal rings of increased FAF have been identified in absence of funduscopically visible correlates, which tend to shrink or enlarge with disease progression, respectively See Figure 6.

Fundus Autofluorescence Imaging in Clinical Use

In patients with geographic atrophy secondary to AMD, it has been shown that—in addition to absence of retinal sensitivity over atrophic areas—retinal function is relatively and significantly reduced over areas with increased FAF intensities compared to areas with normal background signal.

Reductions in serum vitamin A arrest accumulation of toxic retinal atlxs Progression of geographic atrophy and impact of fundus autofluorescence patterns in atlas of fundus autofluorescence imaging macular degeneration. FAF and fluorescein angiography. Book ratings by Goodreads. To reduce the observational period in a slowly progressive disease, to minimize the sample size and to better demonstrate possible treatment effects, the patient recruitment in this study involves the identification of high-risk features in this first large interventional trial in patients with geographic atrophy secondary to AMD.

These abnormalities tend to precede atrophy over time and may serve as disease markers.

Atlas of Fundus Autofluorescence Imaging

It also compares FAF findings with other imaging techniques such as fundus photograph, fluorescein- and ICG angiography as well as optical coherence tomography.

The book is enriched with hundreds of high quality illustrations and fundus autofluorescence pictures as well as od pictures, fluorescein angiography and some microperimetry.

Fundus Autofluorescence Imaging in Clinical Use

The recent introduction of combined simultaneous spectral-domain optical coherence tomography with cSLO imaging, in one instrument with real-time eye tracking that allows for accurate orientation of OCT-scans and therefore for three-dimensional mapping of pathological changes at specific anatomic sites, represents an important step forward to better investigate the origin of the FAF signal within the retina.

The identification of high-risk characteristics, atlas of fundus autofluorescence imaging. Epub Jun These FAF changes remote from visible alterations may suggest more widespread abnormalities and diseased retinal areas.

Recording of FAF is relatively easily accomplished, requires little time and is non-invasive. What causes fundus autofluorescence?

Spaide, CSC accumulates outer segments that have been shed but not yet phagocytized. Melanin has been postulated as the major candidate. Surv Ophthalmol Jan-Feb; Ophthalmologica [accepted for publication ].
