Quantitative evaluation of drusen on photographs.
Visualizing and tracking drusen is important in managing age-related macular degeneration. Color fundus photography (CFP) is common in clinical practice, but quantitative evaluation of drusen in CFPs is difficult because of the varying background of the macula, retinal pigment epithelium (RPE), and choroid. Spectral-domain optical coherence tomography (OCT) provides high-resolution visualizatio...
متن کاملQuantitative comparison of drusen segmented on SD-OCT versus drusen delineated on color fundus photographs.
PURPOSE Spectral domain-optical coherence tomography (SD-OCT) may be useful for efficient measurement of drusen in patients with age-related macular degeneration (AMD). Areas identified as drusen from semiautomated segmentation of drusen on SD-OCT were compared to those identified from review of digital color fundus photographs (CFPs). METHODS Twelve eyes with nonneovascular AMD were prospect...
متن کاملDrusen measurement from fundus photographs using computer image analysis.
Drusen are yellowish deposits at the level of the retinal pigment epithelium and are frequently associated with age-related maculopathy (ARM). Drusen often change in size and number over time and may be followed by atrophic or exudative macular degeneration. A quantitative method to measure the development of drusen is needed for controlled studies of the natural history, prognosis, and treatme...
