Problems with the retina

Seeing a retinal specialist is the right move. Beyond that, other options, like a neuro-ohpthalmologist, will be things you can look at. You will get a diagnosis eventually, just try to be patient- doctors are only human.

How old r u & r u a smoker? Your general ophthalmologist should be able to tell u if u have cataracts. Because the general ophthalmologist would be the one to remove them, so I doubt its cataracts. You may have some changes in the retina which in that case would warrant u to see the retina specialist.

Macular Degeneration is mostly in elderly patients & more pronounced in smokers.

Cataracts is an age related change to the natural lens of ur eye which is in people who r over 50 unless ur were born with congenital cataracts

Retinopathy is in people with Diabetes or long use of any kind of high risk med like Amiodarone, Plaquenil or Prednisone.

A detached retina is unlikely u would have flashing lights, floaters, loss of va like a curtain or window shade covering ur vision.

Good luck! Always good to get more than one opinion

You are doing the best thing possible, which is going to see a retinal specialist.

Best wishes.

It is always good to get a second opinion.

Did you ask him about the intraocular pressure (pressure in your eye)? If its very high, it could be glaucoma.

EDIT: Now glaucoma is ruled out, then I guess it might be the following:

multiple sclerosis - ruled out if movement of the body is fine i.e. no problem with muscles

methanol poisoning - found in anti-freeze, can cause blindness
