Perimetry advances — Dr. Ivey Thornton visual field testing

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…

Domiciliary Optometry: Home-Based Eye Care

Domiciliary optometry — eye care delivered in a patient's home rather than a clinic — is a long-established model in the United Kingdom.

This article describes how the UK model works, what evidence supports it, what limitations apply, and what the analogous…

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…
