Protecting Sight #160: The magic of Fibonacci numbers. Eye Protection for Patients With COVID-19 Undergoing Prolonged Prone-Position Ventilation. Leonardo, Francesco Melzi, and the battle with his father’s heirs.

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 – Arthur Benjamin: The magic of Fibonacci numbers. “Math is logical, functional and just … awesome. Mathemagician Arthur Benjamin explores hidden properties of that weird and wonderful set of numbers, the Fibonacci series. (And reminds you that mathematics can be inspiring, too!)” (ted.com)

2. Cataract Surgery – Uday Devgan MD – Bad Incisions lead to trouble. Dr. Devgan writes, “The challenge in cataract surgery is that each step builds on the previous. A bad incision will cause leakage and iris prolapse. And that means anterior chamber instability and a greater risk of capsule rupture. And then it just goes downhill from there. So what is the best approach?”

3. Sun L, Hymowitz M, Pomeranz HD. Eye Protection for Patients With COVID-19 Undergoing Prolonged Prone-Position Ventilation. JAMA Ophthalmol. Published online November 19, 2020. doi:10.1001/jamaophthalmol.2020.4988

4. Book Chapter – Leonardo da Vinci by Walter Isaacson. Chapter 26. “Return to Milan.” Chapter discusses the death of Leonardo’s father and battles with other heirs. Leonardo “effectively” adopts 14-year old Francesco Melzi in 1507.
