A Mayo Clinic study regarding this poet’s health afflictions doubts glaucoma, suggesting retinal detachment instead

The Final Jeopardy clue for Tuesday, September 22, 2026, appeared in the category “17th Century Authors” and read: “A Mayo Clinic study regarding this poet’s health afflictions doubts glaucoma, suggesting retinal detachment instead.” The clue points to one of the most important English poets of the 17th century, whose blindness has long been discussed by scholars and physicians.

Who Is John Milton?

The correct response is John Milton. Milton, the author of Paradise Lost, became completely blind by the early 1650s, and the exact medical cause of his blindness has been debated for centuries.

Older explanations often suggested glaucoma, but later medical analysis has questioned that diagnosis. A Mayo Clinic study examining descriptions of Milton’s symptoms argued that retinal detachment was a more plausible explanation.

Milton’s Blindness

Milton began losing his sight in adulthood and was blind by the time he produced some of his greatest works. His condition did not end his literary career; instead, he dictated his poetry and prose to assistants and family members.

The loss of sight became closely associated with his public image and with later interpretations of his writing. His blindness is especially striking because Paradise Lost, his best-known work, is filled with elaborate visual imagery despite being composed after he had lost his sight.

Why Glaucoma Was Questioned

For many years, glaucoma was one of the diagnoses proposed to explain Milton’s blindness. However, surviving accounts of his symptoms do not fit every feature normally associated with that condition.

The Mayo Clinic analysis reconsidered the available evidence and suggested that retinal detachment may better explain the progression of his vision loss. Because there are no modern medical records, any diagnosis remains retrospective and necessarily uncertain.

Retinal Detachment as an Alternative Explanation

Retinal detachment occurs when the retina separates from the tissue beneath it, which can lead to severe vision loss if untreated. In the 17th century, physicians had no modern surgical methods for repairing the condition.

The suggestion that Milton may have suffered retinal detachment helps explain why his blindness progressed despite the treatments available at the time. It also shows how modern medicine can revisit historical accounts and propose new interpretations of famous illnesses.

Milton’s Place in 17th-Century Literature

John Milton was one of the dominant literary figures of his century. In addition to Paradise Lost, he wrote Paradise Regained, Samson Agonistes, political prose, and numerous poems and essays.

His work combined classical learning, biblical themes, political argument, and ambitious poetic style. His influence on later English literature was immense, making him a natural fit for a Final Jeopardy category centered on 17th-century authors.

Why This Final Jeopardy Clue Works

This clue works because it identifies Milton through a lesser-known medical detail rather than through his writing directly. The category gives the literary context, while the reference to blindness and the Mayo Clinic study narrows the answer.

The correct response, John Milton, fits every part of the clue. He was a major 17th-century poet, he became blind, and later medical analysis has challenged glaucoma as the cause while suggesting retinal detachment as a possible alternative.
