Protecting Sight #41: The art of the Metaphor. Congratulations to Michael F. Chiang, MD, National Eye Institute Director-Elect! Savoring the last chapters of Moby Dick.

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 – James Geary – Metaphorically speaking (Dec 2009). “Aphorism enthusiast and author James Geary waxes on a fascinating fixture of human language: the metaphor. Friend of scribes from Aristotle to Elvis, metaphor can subtly influence the decisions we make, Geary says.” (

I listened to this talk twice today. Fascinating. As Elvis would sing, “I’m all shook up.”

2. Cataract Surgery – Uday Devgan MD – Challenging Uveitic Cataract. Great case and especially the process to assess a glaucoma tube’s status.

Congratulations to Michael F. Chiang, MD, newly appointed Director of the National Eye Institute. Pictured with David Chang, MD at the Chinese American Ophthalmology Society dinner.

3A. Journal article – Michael F. Chiang MD. How Does the Standard of Care Evolve? Anti-Vascular Endothelial Growth Factor Agents in Retinopathy of Prematurity Treatment as an Example. Ophthalmology. 2018;125(10):1485-1487. doi:10.1016/j.ophtha.2018.04.018.

I remember learning in the first days of medical school that half of what we were taught (and memorized) would no longer be true just a few years later. Great article.

t-Distributed Stochastic Neighbor Embedding Visualization of Features Extracted From an Intermediate Layer of a Trained Convolutional Neural Network for Plus Disease Diagnosis in Retinopathy of Prematurity
“This visualization demonstrates that the convolutional neural network is able to automatically generate features that roughly separate the 3 diagnoses and that they appear to run along a continuum of disease severity.” JAMA Ophthalmol. 2018;136(7):803–810.

3B. Brown JM, Campbell JP, Beers A, et al. and Chiang MF. Automated Diagnosis of Plus Disease in Retinopathy of Prematurity Using Deep Convolutional Neural Networks. JAMA Ophthalmol. 2018;136(7):803–810. doi:10.1001/jamaophthalmol.2018.1934

Congratulations to Michael F. Chiang, MD on his appointment to become Director of the National Eye Institute. Michael and I were residents in Baltimore together two decades ago! Both articles above are excellent and just a sampling of the Director-Elect’s work on moving ophthalmology forward.

4. Book Chapter – Herman Melville – Moby Dick. Listened to Chapters 128-132 via See also Sparknotes (narration) and Gutenberg (book text).

What is it, what nameless, inscrutable, unearthly thing is it; what cozening, hidden lord and master, and cruel, remorseless emperor commands me; that against all natural lovings and longings, I so keep pushing, and crowding, and jamming myself on all the time; recklessly making me ready to do what in my own proper, natural heart, I durst not so much as dare? Is Ahab, Ahab?

Ahab (speaking to himself), Chapter 132

Once I finish Moby Dick – savoring the last few chapters – I plan to find and enjoy 1-2 college level lectures. Usually I look to YouTube, Coursera, or Open Yale Courses. Please send me your favorite lectures!

5. #NoRubberBullets & #NotOneMoreEye Campaign – I reposted my blog on eye safety with rubber bullets & tear gas yesterday. The blog post is here. A shout-out also to Esther Choo, MD MPH @choo_ek who posted the tweet above. Her tweets often go viral and have greatly helped the mission of protecting sight. #TearGasEyeSafety

Please send me feedback. Would appreciate suggestions of Ted Talks, cataract videos, and journal articles to learn from and share.
