Really Informative and well explained. Better than alot of the talks I attend. To the point. I will be going through your other lectures too. Thank you
Expertly explained , and what could be drowned in complicated technicalities wasn't. was easily understood and really interesting, just been to hospital to confirm central serous retinopathy with one of these scans.
Thank u maam.. this video is very helpful after watching video on visual acuity. I just hinge to ur channel and able to understand a load of things..and well wishes. Please keep this CME uptodate
I an an AMD patient. Thank you for helping me understand how the OCT scan at Singapore's SNEC works. I think it must be a combination TD and SD machine, becos it does TWO distinct scans every time: the first is where a thin beam of red light sweeps from top to bottom; the second is a brilliant flashing bluish light. The operator told be it's just part of one and the same examination. Is that possible?
Mam i recently done my eye check up and doctor said me your left eye are underdeveloped and give me specs with smaller number and i previous done i check up on that time the doctor said go for OCT scan so what i do?
Mam as you interference can only happen when two arms are matched in length, then how we calculate sample arms length and match it with reference arm or vice versa? and by matching did you mean oct won’t be appropriate for too long or too short eyes?
The reference arm acts as a fixed baseline, while the sample arm (reflecting light from the eye) varies based on the structures being measured. The OCT device adjusts the reference arm electronically or mechanically to ensure it matches the sample arm length within the coherence length, enabling interference.
In extremely long (myopic) or short (hyperopic) eyes, older OCT systems might struggle because the reference arm range might not cover the extreme lengths. However, modern swept-source OCT and PCI systems like the IOLMaster 700 can handle a wider range of axial lengths due to their improved coherence detection range and advanced algorithms.
Hello , thank you for the simplified explanation , it was very helpful ❤...yet, I have a question , the OCT uses monochromatic wave , so 1 wave length right? But the SD OCT uses broadband light source (the wave lengths are from 840 to 850nm ) which means it should no longer be monochromatic since the wavelengths aren't equal right? And if that's the case, the waves reflected from the layers of the retina will also be of variable lengths. So how does interference happen in this case (since the reference mirror is fixated) 🙃🙃 sorry if this question is confusing .

The best video about oct..Very simple and very neatly explained ❤️
You're a really good physics teacher in addition to being a good ophthalmologist!
The credit goes to my partner!
TOO SIMPLE AND INFORMATIVE THANKS
Excellent opthalmology channel, congratulations, i am pediatrician.
Really Informative and well explained. Better than alot of the talks I attend. To the point. I will be going through your other lectures too. Thank you
Glad you liked it:)
Great ! 👍
You have very easily explained a difficult topic and made it palatable.
Madam your lectures are excellent.
Glad you like them!
Excellent! Thank you for such detailed information.
Glad it was helpful!
I looked everywhere, this is priceless, thank you.
Expertly explained , and what could be drowned in complicated technicalities wasn't. was easily understood and really interesting, just been to hospital to confirm central serous retinopathy with one of these scans.
Thank you 😊
Excellent video ,superb clarity in knowledge 👍🙏🙏
Very informative mam lot of use ful iam optometrist. Plz uplods morer
clear, consice, and easy to understand. Thank you very much!
Excellent job mam,explanation was very basic which is easy for better understanding , waiting for more videos and to gather knowledge from you ..
Couldn't be explained any better🎉
Simply you are the best

Excellent lecture mam.. nicely explained..keep uploading more videos.. thanks a lot..
Thank you, I will
Thanks for the video, is perfect. It would be great to see one from OCT-A (interpretation, print out, etc) 🙏🙌
It's great ma'am, Explained very nicely 🙏🏻
THE BEST explaination!
Dil khush kr diya❤
Really good and clear explanation. Thank you
You're welcome:)

Fantastic explanation, thank you.
Thank you very much!
You're welcome!
Ma'am thank you❤ can you please do IOLs too
Plz keep Long video for deep knowledge
Sure 👍
Mam plz make a video on taking visual acuity in children
GOD BLESS YOU!
Thank you
Notes available for this video?
thank you
thanks a lot🌹
