Ophthalmology | The National EM Board (MyEMCert) Review Course 

Very nice lecture! I enjoyed it. Just want to clarify on "cherry red spot": the retina receives 2 blood supplies (retinal and choroidal vasculatures). When you have an CRAO, the retinal vasculature is completed block. So the whole retina appears pale. In order to produce the most precise vision, the fovea is not covered by retinal vessels - that is, the choroid is the only blood supply for the fovea. That is why the fovea appears bright red in CRAO.

I can’t thank you enough for uploading these are immensely helpful to ED providers all over the world

Hey Great Video! I Just wanted to say- in case of a CRAO, there is no fixed or dilated pupil according to my understanding. CN3 is still intact therefore consensual pupillary response is normal, however as you mentioned direct pupillary response is impaired due to the retinal stroke. The pupil isn't fixed because it still responds to light shone on the consensual eye and is not dilated because its parasympathetic supply is still intact :) It does have an RAPD- shine on the normal eye = both constrict, shine on abnormal eye = return to original size and then shine again on normal eye = both constrict.

thank you for this beautiful breakdown. im now much less scared of eye patients!

the spelling of ophthalmology is much clearer when it is pronounced correctly. the 'ph' when followed by 'th' makes an F sound in English

Explanation for RAPD is just wrong. She explained total APD but not relative.

Prima
