Direct Ophthalmoscopy |Tips and Tricks|

[@bearbear3133]

This is the best and most comprehensive basic explanation of fundoscopy I've ever found! Sometimes, the underlying mechanism is quite the challenge, but here, the image & animation made it easy to tackle. There is also no information overload. And I like how you explain things so clearly ma'am!😊

Thank you!!

[@chitlurnvishwanath3211]

All the videos from insight ophthalmology highly, clearly and very informative videos.

[@InsightOphthalmology]

Thank you !! 😊

I always get blurry image from DO but now I know how to use compensatory lens from your video and will try it. Thank you ma’am for discussing such basic yet important topic.

[@InsightOphthalmology]

Happy to help! With a little practice you will master it soon :)

Yes,enjoyed the video, but I was more curious about the two convex lenses system... Like why there are 2 convex lenses in the ophthalmoscope, what are their power, how much they are separated from each other etc

[@Joei2049]

Thank you so much for this in-depth discussion Dr, been really struggling with this. How do you determine the ratio of the arteries to that of the veins i.e. A/V ratio, I hear the normal ratio is 2/3 but i don't really understand how that is determined?

[@InsightOphthalmology]

It's a rough estimate where we compare the size of the vein and artery near the disc area of the retina. Roughly if we feel that the vein is about 1.5 times larger than the artery, we say it's 2/3. It's very subjective

Mam..please upload video on recent adv..

[@declanlarkin5023]

The field of view you say is lesser in miopes?. That raises a few questions for me [being a physicist's son]. Firstly, when using binoculars the further away the image viewed the more of it you can see - so if the back of the eye is further away should you not see a wider field. The other query is that regardless of the depth of an eyeball does the focusing adjustments/lens diopter we select not correct that focus to the same relative spot. Such that the focal point [on the retina] is where the 2 lines will intersect and needn't be futher apart on hypermetropes as you illustrate [ie because you have selected a more convex lens]? PS No offence, just looking to learn - I'm a first principles type learner - If I can follow the logic I can always remember or work it out again later.

Thanks Dr

[@InsightOphthalmology]

Welcome

[@Doctor09090]

Mam you explain various dipter power with which we can visualize different structures of eyes .....but i try these power but got blur vision...so plzz explain ...in video you explain at 24:33 min

If pt and doctor both had the different refractive erorr means,, how to adjust the lens mam?

[@InsightOphthalmology]

Usually the examiner wears his/her correction during the exam so it's enough to consider the refractive error of the patient. If not then a rough method is to just rotate the lenses and see where we are able to find the clear image. Another method is to find the net refractive error and use the lens accordingly..it is the algebraic sum
