Severe Dry Eye in Thyroid Eye Disease: When PROKERA May Be Part of Treatment

Dry eye does not always stay “just dry eye.” Sometimes it becomes more intense, more constant, and more disruptive than people expect. In thyroid eye disease, that matters because dryness is often not only a tear problem. It can be a sign that the surface of the eye is too exposed, too inflamed, or not healing the way it should. In other words, the symptom may sound familiar, but the cause can be very different.

A quick refresher: thyroid eye disease (TED) is an inflammatory condition that affects the tissues around the eyes. It is most commonly linked to Graves’ disease. TED can make the eyes feel dry, gritty, red, watery, and light-sensitive, and it can also cause swelling, lid retraction, bulging, and double vision. Those changes can leave the front surface of the eye more exposed than usual, which is one reason dry eye symptoms can become severe.

Below are some of the signs that dry eye in thyroid eye disease may be more serious — and when PROKERA may become part of treatment.

1. The dryness feels constant, not occasional

Most people with routine dry eye have ups and downs. Their eyes may feel worse after screens, wind, or a long day, then better with rest or drops. In thyroid eye disease, dryness often feels more persistent. Patients may wake up uncomfortable, feel dry throughout the day, and still feel irritated even after repeated use of artificial tears. TED-related ocular surface disease is common, and research suggests it is driven not only by exposure from bulging or lid retraction, but also by inflammation affecting the eye surface itself.

Why it’s easy to dismiss: Dry eye is so common that many people assume they simply need more drops or a different brand.

2. The eyes water even though they feel dry

This confuses a lot of patients. They think, “How can my eyes be dry if they keep watering?” But watering does not rule out dry eye. In TED, the surface of the eye may be irritated enough to trigger reflex tearing, even while the tear film remains unstable and the eye surface remains poorly protected. The American Thyroid Association notes that open eyelids in TED can cause the eyes to feel dry and can also cause extra tearing.

Why it’s easy to dismiss: Many people assume tearing means the eyes are not dry, when in fact it can be a sign of surface irritation.

3. The eyes feel exposed, especially at night or in the morning

One of the biggest reasons TED-related dryness becomes severe is exposure. If the eyelids are pulled open more than usual, or if the eyes do not close fully at night, the cornea can dry out and become irritated. This is sometimes called exposure keratopathy. AAO describes common symptoms of exposure keratopathy as pain, foreign-body sensation, tearing, light sensitivity, and blurry vision.

Patients often notice this as morning burning, waking up with eyes that feel painfully dry, or the feeling that the eyes are always too “open.” In TED, that symptom matters because it suggests the surface of the eye may not be getting enough protection between blinks or during sleep.

Why it’s easy to dismiss: People often blame nighttime irritation on a fan, air conditioning, or a bad night’s sleep.

4. Blurry vision comes from the surface, not just the prescription

Severe dry eye in TED can make vision fluctuate. Some moments are clearer, and some are blurrier, especially after blinking, reading, or using screens. That happens because the cornea needs a smooth, healthy tear film to focus light properly. When the surface is inflamed or unstable, vision can seem inconsistent even if the glasses prescription itself has not changed. TED-related dry eye is often evaporative and is associated with lagophthalmos, which means incomplete eyelid closure.

Why it’s easy to dismiss: Patients may assume they need stronger glasses, when the bigger issue may be an unstable, exposed ocular surface.

5. Standard dry-eye treatment is not doing enough

Artificial tears are often the first step, and they can be very helpful. But there are times when the eye surface needs more than lubrication alone. If someone is using drops frequently and still has severe burning, redness, light sensitivity, or surface pain, it may mean the problem is not only dryness but also active surface damage or poor healing. Reviews of TED-related ocular surface disease emphasize that this is a common burden in TED and not always adequately addressed by ordinary dry-eye measures alone.

Why it’s easy to dismiss: Many patients keep trying more drops for months because “dry eye treatment” sounds like the obvious answer.

6. The cornea may need healing support, not just moisture

This is where the treatment conversation changes. Once the surface of the eye becomes inflamed or damaged enough, the goal is no longer just to make the eyes feel better. The goal is to help the cornea heal. PROKERA is a self-retained cryopreserved amniotic membrane device used to support healing of damaged ocular surfaces. BioTissue describes it as a medical device used for anti-inflammation, anti-scarring, and healing of damaged eye surfaces. Published literature also describes cryopreserved amniotic membrane as being used for a range of ocular surface disorders.

In practical terms, PROKERA may be considered when TED-related dryness has progressed to significant ocular surface disease, especially when exposure, inflammation, or poor corneal healing are part of the picture. It is best thought of as a surface-healing treatment, not as the main treatment for the entire thyroid eye disease process.

Why it matters: If the front of the eye is struggling to heal, adding moisture alone may not be enough.

7. Severe dry eye can be a clue that the thyroid eye disease itself needs more attention

Sometimes the severe dryness is the main problem. Sometimes it is a sign that the broader thyroid eye disease is also becoming more significant. If the eyes are very exposed because of lid retraction or bulging, or if there are also symptoms like swelling, pressure, or double vision, then treatment may need to address more than the corneal surface. That is why severe dry eye in TED should not be viewed in isolation. It is often one part of a larger disease pattern.

Why it’s easy to dismiss: Patients and even clinicians may focus on the dryness alone and miss the fact that TED is driving the exposure and inflammation.

Why severe dry eye in TED matters

Severe dryness is not only uncomfortable. It can interfere with reading, screen use, driving, sleep, and overall quality of life. More importantly, if the cornea stays exposed and inflamed, it becomes more vulnerable to injury. AAO’s exposure keratopathy guidance makes clear that the cornea can suffer when the eye is not adequately protected. In TED, that makes surface symptoms more than a comfort issue.

This is why patients with thyroid eye disease should pay attention when dryness starts to feel different — more intense, more constant, or less responsive to standard treatment. Severe dry eye may be the symptom that brings someone in, but the bigger goal is protecting the eye surface before damage becomes harder to reverse.

Treatments Available

Treatment often starts with the basics:

• preservative-free artificial tears

• thicker ointment at night

• moisture protection and careful lid closure strategies

• close monitoring of the cornea when exposure is significant

If the surface of the eye is significantly inflamed or damaged, PROKERA may be considered as part of treatment to support corneal healing. It is a biologic corneal bandage made with cryopreserved amniotic membrane and is used for damaged ocular surfaces.

If thyroid eye disease itself is more active or more clinically significant, the treatment plan may also need to address the underlying TED process. That is where broader TED treatments, including disease-directed therapy, may enter the discussion. The right plan depends on whether the main issue is surface damage, active orbital disease, or both.

What to do if this sounds like your eyes

If your eyes are:

• painfully dry

• red or light-sensitive most days

• watering even while feeling dry

• hard to keep comfortable at night or in the morning

• blurry because the surface never feels stable

• not improving with ordinary dry-eye treatment

it may be time to ask whether your thyroid eye disease is causing more serious ocular surface problems.

Action steps

Schedule an eye evaluation, mention any history of Graves’ disease or thyroid problems, and be specific about whether your symptoms are constant, worsening, or not responding to standard treatment. If you are having severe pain, marked light sensitivity, or worsening vision, do not wait to bring it up.

What this means for your eyes

Severe dry eye in thyroid eye disease is not always “just dry eye.” Sometimes it is a sign that the surface of the eye is too exposed, too inflamed, or not healing properly. That is when treatment may need to go beyond drops alone. For the right patient, PROKERA may be one part of that plan — not because it replaces all other TED treatment, but because the cornea sometimes needs active healing support.
