Correct answer: "OAG onsets gradually, initially presenting with little or no symptoms."

Explanation: Primary open‑angle glaucoma is chronic and insidious, often painless, and causes progressive peripheral (not central) visual field loss that may go unnoticed until advanced. Sudden painful onset with blurred vision is characteristic of acute angle‑closure glaucoma, not OAG.
