When having eyes dilated for glaucoma exam can an ophthalmologist detect diabetic retinopathy?

Yes if present : The dilated eye exam is exactly how we inspect the retina, optic nerve , blood vessels, and other parts for diseases.

As it turns out, not having retinopathy (a good thing) doesn't mean that you don't have diabetes. Your primary doctor determines that. ...Read more

How often is a dilation eye exam recommended if no symptoms exist? Which one is better? Digital retina exam or dilated eye exam?

Depends: At your age, & depending on your eye health, a dilated exam every 3 years is probably sufficient. For myopia yearly exams usually are desirable to check on prescription changes.

Digital retinal imaging exams (Retincamâ„¢) work for big pathologies, but not micro-detailed ...Read more

Optic Nerve RNFL OCT shows thinning temporal- both eyes, 20/20 both eyes, IOP 17 both eyes. Retinal exam normal. Is this significant

Optic Nerve RNFL OCT shows thinning temporal- both eyes, 20/20 both eyes, IOP 17 both eyes. Retinal exam normal. Is this significant

These results could be part of Multiple Sclerosis, if other signs and symptoms support the diagnosis. The thinning of the RNFL is notable, and should be followed up. Would a Concierge visit allow more in depth understanding? ...Read more

For example, hyaloid pathology could be secondary to inflammation and carries a different set of issues. A good dilated is rec. ...Read more
