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

HI
Thank for asking to HCM
I really appreciate your concern, if you have suffering from diabetes and it not being controlled well then this may cause the neurological as well as ophthalmic problem as you have it right now, with proper treatment the symptoms would improve much better but most important is to manage the glucose plasma level on tight rule basis for prevent further retinal damage, what ever the symptoms you have it has to correlate with the ophthalmic finding, in sever case result of laser treatment may not be satisfactory, some confusion may be there with floater and flashes, it may not be retinal tear in other eye, hope this information helps.
