I understand.
Hubby's first retinal detachment, he waited to long to see the eye doctor. A week. They sent him to s specialist. Who thought it was just a broken blood vessel in his eye.
Two weeks later he was back, and they did surgery. The worst great retinal tear they had ever seen. And wasn't visible because of the blood.
He never regained his only six month old 20/20 vision in that eye! His cataract surgery six months before had given him better vision than he had had in his life.
Four months, later, the other retina detached. On the same road. Across the railroad tracks, on the way to work.
By the time he got to work, he had no vision.
That surgery was on Monday, only three days later.
The surgeon felt confidant waiting that long. And except for a tiny corner of vision, that eye fully healed.
