Labels and methods are provided for detecting deposits, including drusen, sub-retinal deposits, basal laminar and linear deposits, and the like. The labels can detect the presence, progression, or regression of hydroxyapatite, which can be indicative of the presence or the potential to develop such deposits. The labels can include a conjugate comprising a hydroxyapatite binding moiety and a label moiety, which can provide a detectable signal upon binding of the conjugate to hydroxyapatite. The labels and methods can be utilized to detect deposits in eye tissue, such as the retina, brain tissue, or the like. Methods are also provided for utilizing the present labels to predict or diagnose a neurodegenerative disease, including age-related macular degeneration. Accordingly, some methods can predict or diagnose age-related macular degeneration, including early signs or advanced forms thereof, based on the presence of hydroxyapatite in a tissue sample obtained from a subject. |
