What's the leading cause of vision loss in people over 60? Glaucoma?

Short or long term? The leading cause of correctable vision loss is cataract. Glaucoma causes a slowly evolving loss if unresponsive to treatment and causes much vision loss especially in the third world. The two major causes of uncorrectable loss are diabetes and macular degenration. Diabetes loss is prevalent in the 60's (and younger) while mac degen affects a more elderly age group.
