Protecting Sight #248: The search for the true face of Leonardo. Flip & chop, high myopia, ptosis, myasthenia, and Cogan’s lid twitch.

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 – Siegfried Woldhek: The search for the true face of Leonardo. “Mona Lisa is one of the best-known faces on the planet. But would you recognize an image of Leonardo da Vinci? Illustrator Siegfried Woldhek uses some thoughtful image-analysis techniques to find what he believes is the true face of Leonardo.” (ted.com)

4 minutes and superbly fascinating!

2. Cataract Surgery – Uday Devgan MD – 1016: flip and chop in high myopia. Excellent pearls & technique.

3A. Andrew Lee MD – Diagnostic Approach to Ptosis. Bookmark this video for the next patient who comes in with ptosis.

3B. Dr. Cogan’s sentinel 1965 paper on the Cogan lid twitch: Cogan DG. Myasthenia Gravis: A Review of the Disease and a Description of Lid Twitch as a Characteristic SignArch Ophthalmol. 1965;74(2):217–221. doi:10.1001/archopht.1965.00970040219016
