People with drusen, particularly large drusen, are at higher risk of developing age-related macular degeneration (AMD). [PMC free article: PMC4733883] [PubMed: 26493180]. ) Argon green laser treatment was applied directly to the soft drusen in the temporal macula. One spot of argon green laser (100-microns spot at 100 mW for 0. While it is possible to eliminate drusen with this treatment strategy, it has been shown that this fails to reduce the risk of developing the choroidal neovascularisation which causes the blindness associated with age-related macular degeneration.
