Understanding the Dual Diagnosis: Glaucoma and Dry Eye
Glaucoma is a serious eye condition that causes progressive damage to the optic nerve, often associated with high intraocular pressure (IOP). Treatment is aimed at lowering this pressure and preventing further vision loss. Meanwhile, Dry Eye Disease (DED) is a common condition characterized by insufficient tear production or poor tear quality, leading to discomfort and inflammation.
The two conditions frequently overlap for a few key reasons. Long-term use of preservative-containing glaucoma eye drops, such as those with benzalkonium chloride (BAK), is known to cause or exacerbate DED by damaging the ocular surface. Furthermore, the systemic medications used for glaucoma can also contribute to dry eye symptoms. This can create a challenging situation where the very treatment for one condition worsens another.
The Role of Restasis in Glaucoma Patient Care
Restasis (cyclosporine ophthalmic emulsion 0.05%) is an FDA-approved medication specifically for increasing tear production in patients with chronic dry eye due to ocular inflammation. It is not designed to treat glaucoma or lower IOP. Instead, its purpose is to break the inflammatory cycle on the eye's surface that suppresses natural tear production.
Why Restasis is Safe for Glaucoma Patients
A critical concern for glaucoma patients is any medication's potential effect on IOP. Unlike topical steroid eye drops, which can increase IOP over the long term, Restasis is a calcineurin inhibitor and does not cause this side effect. This makes it a safe anti-inflammatory choice for individuals with a history of glaucoma or those at risk of developing the condition. When prescribed by an ophthalmologist, Restasis can be used in conjunction with standard glaucoma therapies, providing relief from dry eye without compromising glaucoma management.
Combining Restasis with Glaucoma Drops
For patients managing both conditions, proper administration of multiple eye drops is essential to maximize effectiveness and minimize side effects. A common recommendation is to wait at least 15 minutes between different eye drop applications. This prevents the second drop from washing away the first, allowing each medication sufficient time to be absorbed and act on the eye's surface. A doctor will typically provide a personalized schedule to ensure both treatments are administered correctly and effectively.
Comparison: Restasis vs. Glaucoma Medication
To better understand how these medications work together, consider their distinct mechanisms and goals.
| Feature | Restasis (Cyclosporine) | Glaucoma Medications (e.g., Prostaglandins, Beta-Blockers) |
|---|---|---|
| Primary Goal | Increase natural tear production by reducing ocular surface inflammation. | Lower intraocular pressure (IOP) by either increasing fluid drainage or decreasing fluid production. |
| Mechanism of Action | Immunomodulator (calcineurin inhibitor). | Varied, e.g., prostaglandin analogues increase uveoscleral outflow; beta-blockers decrease aqueous humor production. |
| Effect on IOP | No effect; does not increase or decrease IOP. | Reduces IOP, which is the primary therapeutic effect. |
| Onset of Action | Gradual; can take weeks to months for full effect. | Relatively quicker, with some effects noticeable within a few weeks. |
| Primary Indication | Chronic Dry Eye Disease due to inflammation. | Open-angle glaucoma, ocular hypertension, and other forms of glaucoma. |
The Broader Context of Ocular Surface Disease in Glaucoma
Ocular surface disease (OSD) is a spectrum of conditions affecting the tear film and eye surface. For glaucoma patients, OSD can be a major issue, impacting their quality of life and adherence to treatment. Preservative-free alternatives for glaucoma drops are sometimes an option, but for many, a medication like Restasis is needed to address the underlying inflammation.
Beyond simply treating dry eye symptoms, managing OSD with cyclosporine can have beneficial downstream effects. Some studies have investigated whether reducing ocular surface inflammation with Restasis after glaucoma surgery can improve surgical outcomes and patient comfort. By creating a healthier ocular environment, it may enhance the success and longevity of certain surgical procedures.
Conclusion: A Synergistic Approach
In summary, the answer to "Can you use Restasis with glaucoma?" is a definitive yes, provided it's under the guidance of an eye care professional. Restasis effectively manages chronic dry eye by targeting the inflammation that suppresses tear production, an issue common among glaucoma patients, particularly those using topical glaucoma medications. Critically, it does so without affecting the intraocular pressure, which is the primary concern for glaucoma management. By combining these two treatments with careful administration, patients can address both conditions effectively, improving comfort and ensuring long-term eye health.
Always consult with your ophthalmologist before starting, stopping, or changing any medication to ensure it is appropriate for your specific condition..

Proper Application of Multiple Eye Drops
- Start with your glaucoma eye drops as prescribed by your doctor.
- Wait at least 15 minutes before applying Restasis, or any other eye drop.
- This waiting period prevents the different medications from diluting each other or washing out, allowing for optimal absorption.
- A doctor can provide a specific schedule, for example, applying Restasis in the morning and evening, separated from your glaucoma drops.
- Be consistent with your application schedule to achieve the best results for both conditions.
Addressing the Root Cause of OSD in Glaucoma
- Many glaucoma drops contain preservatives that can irritate the eye's surface, leading to or worsening DED.
- Restasis acts as an anti-inflammatory, breaking the cycle of inflammation that suppresses natural tear production.
- By addressing the root cause, Restasis helps restore the ocular surface, improving comfort and potentially making patients more compliant with their essential glaucoma regimen.
- For severe cases, a doctor might combine Restasis with short-term steroids or recommend preservative-free glaucoma drop formulations.
Considerations and Side Effects
- Common side effects of Restasis include temporary burning or stinging, redness, and blurred vision, which often improve over time.
- Restasis is not a steroid, so it avoids the long-term risk of increased IOP and cataracts associated with steroid use.
- It is crucial to use Restasis consistently over several months to achieve its full therapeutic effect.
- If you experience severe eye pain, swelling, or signs of infection, contact your healthcare provider immediately.
