<s>[INST] I have diabetic retinopathy and had a hemmorrage last thursday. Will the floaters in my eye cause me to see shadows that i might confuse with flashes? I did have a retinal tear in the other eye but it has been lasered and has been looked at by my specialist, but could the laser cause me to see lights as well? They are really flashing lights, just more flickers of lights [/INST] Hello, Thanks for the query.Following retinopathy (proliferative) if pre-retinal  bleeding occurs, then the blood is not rapidly cleared from the posterior cavity of the eye. This can affect vision. After a certain period floater remain in the eye which can create some hindrance to the vision. Plus after the laser burns some flash lights are seen. These do not affect vision, but will remain. One need not worry about it. But it is essential to get a periodic retinal examination doen to see if there is any worsening of the existing condition. Plus strict blood glucose control is also a must. Thanks </s>
