Fundus autofluorescence imaging in hereditary retinal diseases

Area of Science:

• Ophthalmology
• Medical Imaging
• Retinal Diseases

Background:

• Fundus autofluorescence (FAF) visualizes intrinsic fluorophores in the retina.
• Lipofuscin accumulation in retinal pigment epithelium (RPE) cells is a key factor in retinal diseases.
• FAF is a non-invasive, rapid imaging method for routine clinical use.

Purpose of the Study:

• To review the basic principles of FAF imaging.
• To summarize FAF findings in various hereditary retinal diseases.
• To highlight the expanding clinical applications of FAF.

Main Methods:

• FAF imaging utilizes intrinsic fluorophores for visualization.
• The technique maps changes in the RPE/photoreceptor complex and macular pigment.
• Data is presented from studies evaluating hereditary retinal disorders.

Main Results:

• FAF detects abnormalities not visible with funduscopy, fluorescein angiography (FA), or optical coherence tomography (OCT).
• It is crucial for differential diagnosis, delineating affected retinal areas, and monitoring disease progression.
• FAF facilitates genotype-phenotype correlations in retinal diseases.

Conclusions:

• FAF is an essential tool for evaluating macular dystrophies and hereditary retinal disorders.
• Its ease of use, non-invasive nature, and diagnostic value increase its clinical relevance.
• FAF imaging provides unique insights into retinal disease pathology and progression.
