Without equivocation, if she did not dilate your pupils then she could not have seen the entire extent of your retina, unless your pupils are naturally 10mm in diameter and stay that way. She can also not rule out a retinal tear, hole, or break or even RD on the basis of how big your PVD is. To attempt to do so is a dangerous assumption. Again, it is still a rare event to get a retinal hole, break, or tear or RD from this event, but you are certainly still at risk. As an ophthalmologist (a Medical Doctor and eye surgeon), I would not be sure that you didn't have a retinal problem unless I dilated your pupils and did a comprehensive retinal exam. In addition, a retinal hole can just as easily turn into a retinal detachment as can a retinal tear or break.
Please let me explain a fundamental difference between optometrists and ophthalmologists. An optometrist is a person who has a college degree who went to 4 years of optometry school to study the general workings of the eyes, but most specifically the optics of the eyes. Their training qualifies them to prescribe glasses, contact lenses, conduct general, healthy eye exams and to facilitate more complex low vision aids for persons with decreased vision. They are usually adept at general eye health concerns, but they are not medical doctors.
An ophthalmologist, like me, is a medical doctor. I have a four year college degree and then attended four years of medical school and graduated with an M.D.. I am, therefore, trained in every process of disease and physiology in the human body. I am a trained surgeon and understand how the diseases of the body in general affect the health of the eye and vice versa. Ophthalmologists have much more training, experience, and knowledge regarding the medical diseases of the eyes because this is the bulk of our training.
I would not advise seeing an optometrist for an urgent or potentially urgent problem with the eyes because many of them do not know the extent to which they don't know important principles.
Yes, you are correct. The general public trusts everything that is said by an optometrist because, for all they know, this person is an "eye doctor." It is true that their optometry degree is a "doctorate" degree and therefore they are eligible to be called doctors. But they are not medical doctors or physicians. They are doctors of optometry.
If this optometrist has established a practice of not dilating patients who have new onset PVDs just because she can see the PVD when the pupil is not dilated, then she is skirting a dangerous path.
