Antidepressants Cause Dry Eyes, Blurred Vision – Doctors Urge Eye Checks

When Ming Wang, MD, an ophthalmologist at Wang Vision Institute, based in Nashville, TN, raised the alarm about eye trouble linked to antidepressants, the numbers were stark: roughly one in five Americans is on a prescription for an antidepressant or anti‑anxiety drug, and many of them report uncomfortable vision changes.

The warning didn’t stop there. Michelle Riba, MD, professor of psychiatry at the University of Michigan Comprehensive Depression Center in Ann Arbor, Michigan, reminded colleagues that blurry vision can tip patients already battling glaucoma or dry‑eye syndrome over the edge. Likewise, Ethan Tittler, MD, a retinal specialist with the Central Valley Eye Medical Group in Stockton, California, noted an odd paradox: some patients cry more because the medication’s dryness triggers a reflex tearing response.

Why Eye Problems Matter

Imagine reaching for a newspaper and the words blur like you’re looking through a foggy window. For a young professional who needs to read a contract, that kind of “near‑focusing difficulty” can feel like a career‑killing snag. The issue isn’t just cosmetic; chronic dry eye can lead to corneal abrasions, increase infection risk, and in severe cases, accelerate cataract formation.

Data from the American Academy of Ophthalmology suggest that dry‑eye disease affects about 16 million adults in the U.S. Adding a medication that further reduces tear production is like turning up the heat on an already simmering pan.

• 1 in 5 Americans take an antidepressant or anti‑anxiety drug.
• Up to 30% of SSRIs users report new‑onset dry‑eye symptoms.
• Patients over 65 on certain agents face a 40% higher cataract risk.

What the Science Says

A recent study published in MedCrave Online examined 212 patients on escitalopram or sertraline. Researchers used the Schirmer test (which measures tear production) and the Ocular Surface Disease Index (OSDI) questionnaire. The longer the drug exposure, the worse the scores – a clear dose‑duration relationship.

Interestingly, while both drugs produced similar Schirmer results, sertraline users tipped the OSDI scale a notch higher, hinting at subtle pharmacodynamic differences. Yet, the study cautioned that the sample size was modest, so broader trials are needed.

Beyond SSRIs, tricyclic antidepressants (TCAs) like amitriptyline bring anticholinergic side‑effects that can dilate pupils (mydriasis) and impair accommodation, sometimes precipitating acute angle‑closure glaucoma in predisposed eyes. Monoamine oxidase inhibitors (MAOIs) add a vascular twist: dietary tyramine spikes can trigger hypertensive crises that manifest as retinal hemorrhages.

Doctors Weigh In

"The most commonly prescribed anti‑anxiety medications are the SSRIs," says Dr. Wang. "They are known to cause near‑focusing difficulty such as blurred vision when reading, related to changes in pupil and ciliary muscle function." He added that younger patients, who rarely need reading glasses, are often the most surprised by the onset of presbyopia‑like symptoms.

Dr. Riba emphasized the compounding factor of pre‑existing eye disease: "Blurry vision can be particularly bad and even debilitating if a patient has another eye condition, such as glaucoma or dry eye." She urges psychiatrists to ask about ocular discomfort during each follow‑up.

From the retinal side, Dr. Tittler observes, "Antidepressant medications are associated with dry eyes. The symptoms frequently coincide with dry mouth, creating that burning, gritty sensation that many patients describe as 'sand in the eye.'" He also notes the paradoxical tearing in some cases, which can confuse patients into thinking they have allergic conjunctivitis.

Risks Across Different Drug Classes

Below is a quick glance at the most common ocular side‑effects by antidepressant class:

1. SSRIs (e.g., fluoxetine, sertraline, citalopram) – dry eye, blurred near vision, potential cataract risk.
2. TCAs (e.g., amitriptyline, nortriptyline) – mydriasis, reduced accommodation, acute angle‑closure glaucoma.
3. MAOIs (e.g., phenelzine, selegiline) – possible retinal vascular changes during hypertensive crises.
4. Atypicals (e.g., bupropion, mirtazapine) – occasional blurry vision, rare reports of ocular inflammation.

Older adults deserve extra attention. A legal analysis by CFK Law highlighted that patients 65 and older on certain SSRIs or TCAs have up to a 40% increased chance of developing cataracts within five years of continuous use.

Recommendations for Patients and Clinicians

For anyone starting or continuing an antidepressant, the rule of thumb is simple: add an eye‑check to the medication routine.

• Ask your psychiatrist or primary‑care doctor about any new eye discomfort, even if it seems minor.
• Schedule a baseline exam with an ophthalmologist, especially if you have glaucoma, dry‑eye disease, or a history of angle‑closure events.
• Consider artificial tears or prescription cyclosporine drops if dryness becomes bothersome.
• If you notice sudden blurry vision, flashes, or halos around lights, seek urgent care – it could signal angle‑closure glaucoma.
• Regularly review medication lists; sometimes a switch to a lower‑anticholinergic agent reduces eye side‑effects without compromising mental‑health benefits.

Ultimately, the goal is to keep the eyes in sync with the mind. When patients understand that their eye irritation might be medication‑related, they’re more likely to report it, leading to earlier interventions and better adherence to both psychiatric and ocular treatments.

Key Facts

• One‑fifth of Americans take antidepressants or anti‑anxiety drugs.
• SSRIs are most often linked to dry eye and near‑vision blur.
• Long‑term use correlates with higher OSDI scores and reduced tear production.
• TCAs can precipitate acute angle‑closure glaucoma.
• Patients over 65 have a markedly higher cataract risk.
