Glaucoma: Your Eye Pressure, Scans and Field Tests as Research Data

Every figure in this guide comes from a published source, linked where it appears and kept in CureCircle's evidence base with the source's own words. It is not medical advice. Read on 7 November 2026.

Glaucoma takes sight slowly and quietly, which is why it is followed so closely: pressure readings, scans of the optic nerve, visual field tests, every year or more often, for life. Each visit adds a measurement, and together they show whether treatment is holding the disease still. Those long series of eye scans and tests, with the person's own account of drops, side effects and what they notice in daily life, are exactly what research on glaucoma, including AI that reads eye scans, learns from.

How many people live with it

A study in the American Journal of Ophthalmology estimated that the number of people aged 40 and over with open-angle glaucoma was 80.5 million in 2024, rising to 186.6 million by 2060. Among people aged 40 to 79, about 23.46 new cases per 10,000 people arise each year.

The records worth keeping

NICE's guideline on glaucoma describes the tests and treatment that leave records:

• An optic nerve image at diagnosis: NICE says to obtain an optic nerve head image at diagnosis for baseline documentation, often an OCT scan. Later scans are compared with it.
• Regular reassessment: for stable glaucoma, between 12 and 18 months for low risk, and between 6 and 12 months for high risk. Each visit records pressure and often a visual field test.
• Eye drops or laser: a generic prostaglandin analogue eye drop if laser treatment is not chosen or not suitable. Your prescription history shows every change.
• The referral letter, which should come with the results of all examinations and tests.

If you do not have your scan reports or field tests, ask your eye clinic for a copy.

What sharing it is worth

CureCircle values every contribution with a public benchmark built from what health data has sold for. A complete glaucoma story with the records the guideline lists comes to about $172 per licence on the benchmark today, and about $329 per licence with four eye scans added as image files. Every line and its source is on the glaucoma page.

A licence is not a one-off sale: the same de-identified story can be licensed to several research teams, and you earn a share each time.

How to share it

You start by writing what you live with in your own words; a few quick questions follow, then an AI interviewer asks about the details only you know, and you rate every treatment you tried, from drops to laser to surgery. You can add scan reports, field test printouts, clinic letters and the scans themselves as PDFs or photos, and the AI reads them into your own medical file. Before anything is shared, you read the de-identified summary and decide.

Start your story, or read what your health data is worth first.
