In the past I have experienced some visual disturbance when taking steroids, usually start up when reducing the dose after 30mg a day for ten days. This time I had my own private 'firework show' seeing bursts of bright light and areas with fragmented vision in both eyes. After this had been happening for half an hour I phoned 111 who advised that I should see a GP 'within two hours'. Was seen really quickly by a GP at my local practice and he referred me the Eye Clinic the following day. The doctor there said that it was almost certainly a side effect of the steroids. Has anyone else experienced this?
