Protecting Sight #203: Grit: The power of passion and perseverance. Floppy iris, direct chop, and AI for sea-fans in sickle cell retinopathy. Elihu Yale & the fortune made from Indian jewels.

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, podcast, or significant work.

Here is today’s list:

1. Ted Talk – Angela Lee Duckworth: Grit: The power of passion and perseverance. “Leaving a high-flying job in consulting, Angela Lee Duckworth took a job teaching math to seventh graders in a New York public school. She quickly realized that IQ wasn’t the only thing separating the successful students from those who struggled. Here, she explains her theory of “grit” as a predictor of success.” (

My claim to fame is that Angela Lee Duckworth and I were in the same high school French class (Madame Rollins)! I’ve watched this talk numerous times and have also listened to her podcast, “No Stupid Questions“. For those, like me, who suffer from Imposter Syndrome, this talk is most helpful.

2. Cataract Surgery – Dr. Neto Rosatelli – Phaco Clip #120 Floppy Iris and Direct Chop. Great technique & Dr. Rosatelli shares excellent pearls in the subtitles.

3. Cai S, Parker F, Urias MG, Goldberg MF, Hager GD, Scott AW. Deep Learning Detection of Sea Fan Neovascularization From Ultra-Widefield Color Fundus Photographs of Patients With Sickle Cell HemoglobinopathyJAMA Ophthalmol. Published online December 30, 2020. doi:10.1001/jamaophthalmol.2020.5900

AI will continue to transform ophthalmology in the years ahead.

4. Diana Scarisbrick and Benjamin Zucker. Elihu Yale: Merchant, Collector & Patron. Part II, Chapter 1, “A Fortune From Jewels.” Fascinating chapter on the India-London diamond trade. The book mentions 17th century merchant Jean-Baptiste Tavernier (Wikipedia), who wrote a detailed guide to the Indian trade & the map above. A most-interesting YouTube video below on today’s diamond mining industry.

5. Diamond Mining in Panna, India (YouTube).
