MOSCOW - Dozens of partygoers at an outdoor rave near Moscow last week have lost partial vision after a laser light show burned their retinas, Russian health officials said on Monday. Moscow city health department officials confirmed 12 cases of laser-blindness at the Central Ophthalmological Clinic, and daily newspaper Kommersant said another 17 were registered at City Hospital 32 in the center of the capital. Attendees at the July 5 Aquamarine Open Air Festival in Kirzhach, 50 miles northeast of Moscow, began seeking medical help days after the show, complaining of eye and vision problems, health officials told Reuters. http://www.msnbc.msn.com/id/25675477/?GT1=43001
