Hello Marianne and Leonard,
I can understand how difficult it must be, especially with the decision to operate in a day.
The causes of a retina detachment can be many. Likely, the hemorrhage was a manifestation of the underlying cause.
What was diagnosed 3 months ago during the initial hemorrhage? The most common that we see are bleeding due to diabeties. If not due to diabeties, then due to hemorrhagic PVD.
Let me explain, a PVD or posterior vitreous
detachment is when the gel within your eyes liquifies, collapses on itself and start to pull away from the the walls of the eye. This is a normal process and not bothersome to most people. Sometimes, the gel is firmly attached to the different parts of the wall of the eye (blood vessels, retina). If this is the case, when it pulls away, it can cause bleeding, or retinal tears or holes.
A retinal tear or hole puts you at risk for a retinal detachment
. If caught early enough, it can be lasered to strengthened (like spot-welding) the surrounding retina. There are cases where tears and holes are missed, despite having a good and thorough exam.
Without knowing more about the details, it's diffcult to get be specific, but I suspect it may be one of those 2.
Tumors of the eyes can also causing bleeding. I suspect that is why they did the blood work and chest Xray. Tumors of the eye can be easily seen though. I suspect the bleeding was bad enough, that they couldn't see anything but blood.
I wish you husband well. The surgery can be pretty involving and after the surgery, the doctor may ask you to be in certain positions (face down, right side...) if there is gas in the eye to help the retina stay attached. This can vary from 2 weeks to 6 weeks.
