How to detect Myopia on the OCT scans?





Hello dear colleagues and students! Today I'm here to tell you how to detect Myopia on the OCT scans by detecting pathological signs of this disease.

This is a scan of our male patient who has Myopia. But if you imagine that you don't know how to detect the disease, what pathological sign you spotted at first?
I believe, 90% of you notice RPE disruption first.

However, RPE disruption is a pathological sign that can be presented in most diseases, be it Wet Amd, DR, Choroidal neovascularization and others.
That is why let's move to the next obvious pathological sign - Ellipsoid zone disruption.

Well, I must agree, Ellipsoid zone disruption is also very common, so let's not stop here.
Now take a look at this pathological sign - Neurosensory retina atrophy.

And the next - Subretinal hyperreflectivity.

Although, OCT scans with myopia or degenerative myopia is quite easy to detect, because they have a specific form, you must remember that these 4 pathological signs are a "starter pack" for Myopia.

I took all these scans from our free education app, where I and my team of retina experts gathered thousands of interesting cases of the most common diseases. I would appreciate if you could test our app and tell me what you think:

Thank you again for your posts.
The first thing I notice from a scan like that is the posterior bulging of the sclera.

I am new to the idea of subretinal hyperreflectivity of the sclera of the posterior pole. Can that be a type of fibroblast proliferation induced by the scleral elongation, i.e. a scar? Is that evidence that pathologic myopia has an inflammatory component? Crazy ideas.
