The Unseen Epidemic

A patient can have 20/20 vision and a normal OCT yet struggle to drive at dusk or function in dim light. The Unseen Epidemic shows primary eye care professionals why impaired dark adaptation may be an early, measurable signal of retinal dysfunction—before structural changes appear on routine imaging.

Written for optometrists, general ophthalmologists, and practice owners, this practical guide explains rod-mediated vision, the evidence linking delayed dark adaptation with retinal disease risk, and how to select patients, perform testing, interpret results, and determine when to monitor, investigate, or refer.

It focuses on patients over 50, those with diabetes or a family history of AMD, users of potentially retinotoxic medications, and patients reporting night-driving difficulty.

The book also examines implementation and economics: wearable testing can fit into staff-led workflow, complement OCT and fundus imaging, support eligible diagnostic services, and distinguish a practice through proactive retinal care.

The Unseen Epidemic helps clinicians act sooner to protect patients' safety, independence, and sight.
