Sorry to hear about your husband but I'm glad that he is on the mend.
I am a retina surgeon and can tell you for a fact that this has nothing to do with stress.
The flashes of light and floaters tell me you are having a posterior vitreous
detachment....here is some information on this issue:
You are likely experiencing a PVD or posterior vitreous detachment, a common event that happens in many people.
You have a thick gel material in the middle of your eyes called the vitreous. Over time as it liquefies, this gel material collapses on itself, forms little clumps that you can see as dots, lines or bugs. As these clumps form the vitreous pulls away from the wall of the eye. In the process it can stimulate the retina -- causing the flashes that you may see.
It is recommended that you see your ophthalmologist to look at the retina to make sure there are no problems such as a retinal hole or tear. In most cases, there are no problems, but this exam is precautionary and allows for preventative treatment of any lesions that are found.
If you notice a sudden increase in floaters, flashes of light (like a lightning storm), or a shadow/veil in the periphery of your vision, this can be worrisome for a retinal detachment. You would need to contact your ophthalmologist promptly in that case.
I am concerned about the vision changes you are having out of the corner of your right eye. I believe the reason you notice poles looking curved is because your retina in that area is detached and bowed forward, causing straight things to look curved.
I would be a lot happier if you could be seen by an eye surgeon tonight. If that is not possible, do not lift, bend, or carry heavy objects. Rest your eyes and go to sleep. Watching TV is ok but I would rather you not read and for sure do not shake your head/eyes.
Do not eat or drink anything after midnight (not sure what time it is on your side of the world; it is 9 pm Thursday here) except for a sip of water to take your usual medicines. Expect that you will be having eye surgery
Does this make sense to you?
