Knock Knock Eye: Why Are My Eyes So Sensitive to Light?

Description

This week I ran into something online that made my ophthalmologist brain short-circuit: a brand-new CDC statement about autism and vaccines that… let’s just say does not follow how science actually works. So I’m breaking down the logic, the frustration, and why “prove it’s not true” is one of the worst arguments in medicine.


Then, because I can only rant for so long before needing to retreat into eyeball science, I walk through two new “Signs & Symptoms” differentials, light sensitivity and anisocoria. Plus, I got strep throat on a cross-country flight, which I do not recommend at age 40.




Takeaways:




  • Why the CDC’s new autism/vaccine phrasing misunderstands the entire concept of scientific evidence.




  • How to think about light sensitivity like an ophthalmologist (hint: start with the cornea).




  • A simple trick for figuring out which pupil is the abnormal one in anisocoria and why it matters.




  • Why strep throat hits like a freight train once you’re over 35, especially in the middle of a business trip.




  • A reminder that neuro-ophthalmologists are magical creatures who can diagnose a Horner syndrome with nothing but a dark room, a penlight, and an unreasonable amount of patience.
