Glaucoma and Depression: A Large Review Finds a Link, but Not the Direction

Glaucoma is usually discussed in numbers: eye pressure, nerve-fiber thickness, visual-field scores. Living with a lifelong, sight-threatening condition also affects mood. A systematic review in the journal Depression and Anxiety pulled together the research on depression among people with glaucoma.

What the researchers did

The team searched ten databases through March 27, 2026, and included 49 studies. Sixteen studies, covering 14,030 people with glaucoma and more than 4.4 million people without it, were used to compare the odds of depression between the two groups. Thirty-eight studies with 21,705 glaucoma patients were used to estimate how common depression is in glaucoma.

What they found

• People with glaucoma had about 2.8 times the odds of depression compared with people without glaucoma.
• About 26% of people with glaucoma had depression or depressive symptoms, although estimates varied widely between studies.
• The link held up when the authors removed studies with self-reported glaucoma, unclear diagnosis, or one very large database study.
• Long-term evidence was limited. One UK Biobank cohort suggested people with glaucoma had a higher later risk of hospitalization for depression.

What the study cannot tell us

The authors rated the certainty of the evidence as very low, because the studies were observational and very different from one another. It is not clear whether glaucoma leads to depression, depression affects glaucoma, or both influence each other. They suggested eye care should include practical depression awareness and referral pathways.

What I tell patients and families

• Feeling worried or low after a glaucoma diagnosis is common, and it is worth mentioning at your visit.
• Low mood can make it harder to keep up with drops and appointments, so support helps both mind and eyes.
• If you notice persistent sadness, loss of interest, or sleep changes, talk with your primary care doctor or a mental health professional.
• If you are in crisis, call or text 988 in the United States.

At Khanna Vision Institute we try to make glaucoma care a conversation, not just a set of measurements. For more plain-language reading on eye conditions, see pieineye.com.
