A nurse is providing education to a 70-year-old client newly diagnosed with open-angle glaucoma. The client asks why they were not aware of any vision problems until the disease was already advanced. Which explanation best describes why open-angle glaucoma is often detected late?
- Open-angle glaucoma progresses slowly and initially affects peripheral vision, which clients frequently do not notice.
- Open-angle glaucoma causes sudden, painful pressure spikes that clients often attribute to headaches.
- Open-angle glaucoma primarily causes central vision loss first, making it difficult to read but easy to overlook.
- Open-angle glaucoma causes increased tearing and eye redness that clients mistake for allergies.
