My wife had sudden blurred vision back in January. She had prolific retinal detachment due to complications with diabetes. She described it as a blurry mass in both eyes and a line down the center of her left eye, giving her splitscreen vision. Due to insurance complications we weren't able to get surgery until April. The surgeon chose to do one eye at a time, so we decided to do the left eye first. The doctor said the surgery went well, reattached perfectly with minimal scar tissue removed, and he used a silicone bubble to hold the retina in place. It's been six months now and during our last check up he said the retina is healing well and the oil bubble is holding in place. However there might still be a little fluid behind the retina that needs to drain on its own before she can see again. Right now, her vision is completely black in that left eye, and her right still remains detached. I fear that if we delay any more action she could lose her vision completely.
Should I get a second opinion on this or is this normal for this type of surgery?
