This is an extraordinarily complicated case. It is unlikely that the flashing is due to traction on the retina since this would likely have been 100% relieved by the massive surgery. I think her retina is damaged and sick and irritable. She is having both "positive" symptoms which are the flashing and colored swirling experiences, and "negative" symptoms which are the blobs where information is missing. You are in highly experienced hands and should refer all concerns to surgeons knowledgeable about her case.
We certainly are staying in close consultation with the doctors. Just hoped we might get some additional insight. We are well aware of the dicey situation we are in. Thanks for your advice.
Call the doctor and let him/her know of the flashes and other symptoms as it could be a sign of redetachment.
Some residual flashes after surgery are normal, after surgery, however, combined with the other symptoms a thorough exam is necessary.
Vision with silicone oil will be worse than without it.
Given all the problems your gf's prognosis is guarded and she should remain under the care of an experienced ophthalmologist.
Also, consider some help from a low vision specialist if her vision loss impacts her daily life significantly.
Thank you Dr. Brown. Could you explain: "She is having both "positive" symptoms which are the flashing and colored swirling experiences, and "negative" symptoms which are the blobs where information is missing."?
Why should we consider flashing and colored swirling to be positive symptoms? Also, to clarify, her blobs are not black. She doesn't have any black areas; the blobs are where the colored swirling is. She has experienced "flashing" and "sparkling" in the blob areas. She has noticed the blob area shrinking slightly over the last couple weeks, but it is still quite predominant.
