Im sorry to hear about your symptoms. Now a negative after image is a part of normal vision in many individuals. these can occur after focusing on a bright light for a period of time and can last for 2-3 seconds afterwards. This can also occur when you change from a dark to extremely bright environment. It can also occur if you have had surgery like cataract surgery etc. Now it is very rarely a sign of serious eye disease and since you have had the OCT test done that indicates that major issues are unlikely.

Now there are diseases which can cause increased appearance of negative afterimages, for example this can occur in autoiimmune retinopathy. This is a condition in which the body targets it own retina with antibodies however that too should show up on the OCT test because the OCT looks directly at the retina to rule out any retinopathies. However it would still be wise to get this evaluated by visiting an opthalmologist. He can do a fundoscopy in his office to look for any changes and then proceed for further testing if necessary.

But in almost 95% of the cases, presence of negative afterimages are normal but if these are persistent, as they are in your case then an eye exam is necessary. You can talk to your opthalmologist about autoimmune retinopathy among other things.
