In this episode I explore the science behind eye dilation and whether there’s a way to reverse it (spoiler: there isn’t). I also discuss space blindness, a phenomenon astronauts experience due to fluid shifts in microgravity, and what NASA is doing to combat it.

Takeaways:

You Can’t Reverse Eye Dilation (Safely): Dr. Flanary explains why pilocarpine, a medication that constricts pupils, isn’t an effective solution for reversing dilation and can even increase the risk of retinal detachment in nearsighted individuals​.

Space Blindness Is a Real Condition: Long-term space travel can cause swelling of the optic nerves and changes in vision due to fluid shifts, leading NASA to study ways to mitigate these effects​.

Cataract Surgery Patients Say the Darndest Things: Light sedation during cataract surgery makes patients extra chatty, leading to some hilarious surgery-day stories, including unexpected marriage proposals from patients​.

What Causes Ocular Rosacea? This chronic eye condition is linked to facial rosacea, causing redness, irritation, and even corneal inflammation in severe cases​.

Amniotic Membrane Transplants Are a Game Changer: Donated placental tissue is being used to heal severe eye injuries and neurotrophic keratopathy, proving that amniotic tissue has powerful regenerative properties​.
