Your assessment and "odds" by your retina surgeon are the best indication of what improvement might be expected. Silicone oil is used in only the most severe and recurrent retina detachments and before the oil was available almost all of these eyes went completely blind. I would suggest you use the search feature and archives and read the many helpful posts and discussions by people that have had this type of surgery and their concerns and frustrations, it will be very helpful to you and has been discussed often. Also remember to take special care of your other 'good' eye by regular examinations, avoiding eye injury and living a healthy livestyle (regular medical exams, no smoking, no excess alcohol, no cannabis, watch blood pressure, cholesterol, blood sugars, weight and exercise, wear proper eye protection) JCH MD
