Strategies for Following Dry Age-Related Macular Degeneration

Spectral domain optical coherence tomography (SDOCT) provides a novel strategy for imaging and monitoring progression in patients with age-related macular degeneration (AMD). The advantage of SDOCT over other imaging modalities or functional tests is that one modality can be used to image both drusen and geographic atrophy while obtaining reproducible, quantitative data on both drusen morphology and the area of geographic atrophy. Moreover, this strategy enables the clinician to follow the disease as it progresses from drusen to both geographic atrophy and choroidal neovascularization. No other imaging modality is able to quantitatively assess all forms of AMD. This unique feature of SDOCT makes it the ideal imaging modality for monitoring patients with AMD, providing routine care, and for following patients in clinical trials designed to assess the efficacy of new drugs for the treatment of dry AMD
