Nutrition and Eye Health: Why Protein Matters

Nutrition and eye health are connected in ways patients sometimes underestimate. The structures of the eye — the lens, the retina, the optic nerve — are metabolically demanding tissues that depend on a steady supply of specific nutrients. Among the macronutrients and micronutrients that matter, protein plays a quiet but important role. This article looks at why protein matters for the eye, how much an adult typically needs, and how protein fits into the broader nutritional picture for long-term ocular…

Perimetry: Advances in Visual Field Testing

Perimetry — the formal mapping of the visual field — has been a foundational tool in ophthalmology for over a century. Goldmann perimetry, the manual technique developed in the 1940s, set the standard for how we evaluate the visual field for decades. The transition to standard automated perimetry in the 1980s made testing more reproducible and easier to perform. The next set of advances is changing the rate at which we can detect disease progression — and that has clinical…

Eye health is a lifelong project. The conditions that cause vision loss in adulthood — cataracts, age-related macular degeneration, glaucoma, diabetic eye disease — develop over years or decades, often silently.

What I’ve Learned in Twenty Years of Eye Surgery

This is the personal essay among the more clinical articles on this site. I've thought about putting it down for some time, and the request to mark twenty years in practice was the right occasion. The lessons that matter most to me as a surgeon — the ones that shape how I work today — are not the technical ones. The technical knowledge is the floor. What matters more, decades in, is the framework that surrounds the technique. The right…
