Yes, they probably have a better background to be a neurosurgeon that specializes in lesions that compress the chiasm too. This statment makes it difficult for me to take anything you say too seriously.
Also, I have big problems with some of the above listed "primary care " eye tasks.
Ordering CT/MRI - how many of these do you order in your training? Some comprehensive ophthalmologists worry about ordering MRI because they may not order the correct series or may not be comfortable reading it themselves. Many community radiologists struggle at reading these. If you are not as good as they are, you are waiting time and money and more importantly may hurt patients.
Glaucoma care: I have observed some ODs that can handle some of this. However, a recent OD referral from a doc just out of training to our practice regarding a patient with worsening visual fields over the past year made me wonder. The referral letter even mentioned "I did not perform gonioscopy." What a comical statement given the fact she showed up in chronic angle closure OU with a 20 degrees of visual field left in the right eye. Any MD or OD can miss things. If you cannot do or do not do gonioscopy you have no business treating glaucoma.
Diabetic Retinopathy - Severe diabetic retinopathy is not becoming rarer. There is more diabetes in this country and people with access to healthcare are becoming diagnosed at earlier stages. For many this does little for prognosis. Overall, it has added to the number labeled with the diagnosis "diabetes" - some with blood sugars of 130 on no meds. Anything beyond background diabetic retinopathy does not belong in an OD office.
Amblyopia/Strabismus - A recent discussion on this board on how to prescribe glasses for various refractive errors by a pre-od member forces me to place this on the list. The various answers (and there were plenty) make me feel this must not be taught well in certain curriculums. If you cannot give answers that make sense to a pediatric eye expert, you should not be treating this.
New Flashes and floaters - For many reasons...
I really would rather not enter this argument again, but this post shows a vast ignorance of OD training. Your glaucoma story is an anecdote and proves nothing. I can give you anecdotes about patients who've seen OMDs too, but all it prove is there are dumb OMDs out there just like there dumb ODs.
Optometrists shouldn't care for anything other than background DR? Why not? Just because you say so?
And again, I still don't understand the lack of outrage from OMDs about primary care docs, and PAs and NPS for that matter, treating all red eyes with sulfacetamide. If you guys want to spout off about how ODs shouldn't be dealing with glaucoma or diabetes or amblyopia or flashes/floaters, how about you get your own house in order first. Then we'll talk.
