Funnel retinal detachment, loss of eye?

Would welcome some advice please.

Here's a quick summary. I was born with a cataract in my left eye and have seen on a very limited basis as I never received a lens implant. I recently went to the ophthalmologist due to a hemorrhage blood vessel in my left eye.

After a few visits I found out that I have a severe funnel retinal detachment. Two doctors both agree that an operation has a very low chance of success. Right now I've come to terms with being blind in that eye forever but, i'm trying to do what I can to save that eye. I'm still pretty young (30) and wouldn't would like to do everything in my power to not have a glass eye.

There is neovascularization of the iris, small eye and the eye won't dilate at all.

If I leave that eye alone and treat it well, is there a chance it will go on living? Both doctors think I'm going to lose it but have no idea on time frame. I can see a bright light if shined directly in to the eye but that's about it.

Pretty sad about all this.
