Protecting Sight Daily Learning #32: Drawings that show the fragility of Earth. White cataracts are as dreaded as Moby Dick. Yale’s Jackson Institute hosts a superb free webinar on the future of great power conflict.

Welcome to day #32 of my daily learning journal. My goal is to watch one Ted Talk and one cataract surgery each day. In addition, I 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 – Zaria Forman: Drawings that show the beauty and fragility of Earth “Zaria Forman’s large-scale compositions of melting glaciers, icebergs floating in glassy water and waves cresting with foam explore moments of transition, turbulence and tranquility. Join her as she discusses the meditative process of artistic creation and the motivation behind her work. ‘My drawings celebrate the beauty of what we all stand to lose,” she says. “I hope they can serve as records of sublime landscapes in flux.’ ” (

I was drawn to this 7-minute Ted Talk based on the title. Filled with extraordinary compositions and lifelong lessons. And I think I’ve taken more screenshots (around 20) than any other Ted Talk. Now I need to learn how to draw!

2. Cataract Surgery – Uday Devgan MD – Cataract Quiz: Argentinian Flag Sign. Excellent teaching case. Uday’s cases are a must-see everyday.

Right eye. A, Widefield photograph (Optos) showing vascular attenuation, with reduced vessel caliber in the macula (asterisks) and vessels sclerosis in the periphery (black arrowhead). There is a small area of hyperpigmentation in midperiphery just superior to the optic nerve (white arrowhead). B, Fundus autofluorescence image showing peripheral hypoautofluorescence, with mottling in the midperiphery (particularly nasally) contrasting a ring of hyperautofluorescence in the macula.

3C. Video learning – Laser Peripheral Iridotomy: Tips and Tricks (Malik Y. Kahook, MD) (YouTube). Great review of LPI pearls.

4. Book Chapter – Herman Melville – Moby Dick. Listened to Chapters 78-80 via See also Sparknotes (narration) and Gutenberg (book text).

5. (BONUS) – The Jackson Institute at Yale hosted a free webinar today on “The Future of Great Power Conflict.” Included an all-star faculty and the moderator addressed the numerous questions posted via Zoom (including, “Governor Howard Dean just asked …”). The session concluded with numerous teaching points including the potential rise of India.

Please check out my historical documents collections at the Yale Library here. I shared a 5th collection which I recently donated — the private papers of a State Department official and US Ambassador during the Cold War — with Professor Gaddis a few months ago.

Professor Gaddis graciously responded, “Thanks for the heads-up on this.  I’m always interested in new archival materials that I can put my undergraduates to work on.” Stay tuned!
