. About 7 yrs ago I got knocked over by a woman's pushchair & hit my head the first time, trauma can cause the detachment, I had headaches for 3 weeks after & floaters then when it finally detached I had bright light flashes & floaters got worse it seemed like I'd got big black spiders crawling over my face, not ashamed to say I screamed, frightened the life out of me, thought they were spiders, I'm petrified of spiders, went straight to A&E they told me that's when it finally detached, but this eye now has othere problems also, before I had a Periphial tear, and a bleed and had it lazerd, got macular so that's added risks, the detachment happens to most people after 50urs old cos of age doctor said, so it would probsbly happen anyway at sometime, but was told this can happen after catarach op but I didn't know that, everythink has risks. My othere eye is ok I presume, it has macular but, just got to get on with it, stress will only cause more problems, sorry been moaning to long I do apologise
