Protecting Sight #125: Using “The Force” to monitor vital signs. Zonular dehiscence, ROP, angiographic abnormalities, & anti-VEGF agents. What’s your personal vision?

Welcome to my daily learning journal. My daily goal is to watch one Ted Talk and one cataract surgery. I also plan to read one journal article and read/listen to a book chapter, short story or significant work.

Here’s today’s list:

1. Ted Talk – Dina Katabi – A new way to monitor vital signs (that can see through walls). “At MIT, Dina Katabi and her team are working on a bold new way to monitor patients’ vital signs in a hospital (or even at home), without wearables or bulky, beeping devices. Bonus: it can see through walls. In a mind-blowing talk and demo, Katabi previews a system that captures the reflections of signals like Wi-Fi as they bounce off people, creating a reliable record of vitals for healthcare workers and patients. And in a brief Q&A with TED curator Helen Walters, Katabi discusses safeguards being put in place to prevent people from using this tech to monitor somebody without their consent.” (

2. Cataract Surgery – Uday Devgan MD – Cataract Quiz: What happened here?. Dr. Devgan writes in part, “Our quiz features a video from Gustavo Hüning, MD, MBA from Brazil and it shows an unusual situation that happens during IOL insertion.” Have enjoyed watching Dr. Hüning on many webinars in the last few months. Excellent teaching case.

3. Journal – Shah N, Gupta MP, Chan RVP. Persistent Angiographic Abnormalities After Intravitreal Anti–Vascular Endothelial Growth Factor Therapy for Retinopathy of PrematurityJAMA Ophthalmol. 2018;136(4):436–437. doi:10.1001/jamaophthalmol.2017.4172

4. Book Chapter – The Swiss Family Robinson by Johann David Wyss – Chapter 28-31. (Gutenberg | enotes)

Berkshire Hathaway meeting 2018

5. “What’s Your Personal Vision?” – Sean Murray (Real Time Performance) – 3 minute read. I met Sean while standing in line at the Berkshire Hathaway meeting (we probably got in line around 4 am!). Sean’s got a great blog and podcast. Enjoyed his podcast episode on stoicism, which led me to Marcus Aurelius’ Meditations a few months ago.
