Ehlers-Danlos Syndrome and Your Eyes: What Patients Should Know
Updated: Sep 21
What Is Ehlers-Danlos Syndrome?
Ehlers-Danlos syndrome, often called EDS, is a group of inherited connective tissue disorders. Connective tissue helps support the skin, joints, blood vessels, ligaments, and many structures in the eye. People with EDS may have joint hypermobility, stretchy skin, fragile tissue, chronic pain, easy bruising, or delayed wound healing.
Because the eye contains collagen-rich structures such as the cornea, sclera, vitreous, and blood vessels, EDS can sometimes affect vision and eye health. The exact risk depends on the type of EDS, since different forms affect different types of collagen and connective tissue.
How Can Ehlers-Danlos Syndrome Affect the Eyes?
Many people with EDS have normal eye exams, but certain eye findings are seen more often in patients with connective tissue disorders. These can include:
1. Dry Eye
Dry eye is one of the more common eye complaints in people with hypermobility-related EDS. Patients may notice burning, stinging, fluctuating vision, redness, tearing, light sensitivity, or contact lens intolerance.
Dry eye can happen for many reasons, including tear film instability, eyelid laxity, inflammation, and incomplete blinking. In some patients, dryness can also contribute to recurrent corneal irritation or erosions.
2. Nearsightedness and Frequent Prescription Changes
Patients with EDS may be more prone to myopia, or nearsightedness. Some may also have astigmatism or prescription changes over time. A comprehensive eye exam can help determine whether blurred vision is from a simple glasses prescription change or from another issue involving the cornea, lens, or retina.
3. Corneal Changes
The cornea is the clear front window of the eye. Since the cornea depends on collagen for strength and shape, some connective tissue disorders may be associated with corneal thinning, abnormal curvature, or conditions such as keratoconus, where the cornea becomes cone-shaped and causes distorted vision.
Symptoms of corneal changes can include ghosting, glare, halos, light sensitivity, blurry vision that does not fully improve with glasses, or rapidly changing astigmatism. Corneal topography or tomography may be recommended if keratoconus or corneal thinning is suspected.
4. Blue Sclera
Some patients with EDS may have a bluish tint to the white part of the eye, called blue sclera. This can happen when the sclera is thinner than usual, allowing the darker underlying tissue to show through. Blue sclera does not always mean there is an active eye problem, but it can be an important clue that the eye’s connective tissue may be more fragile.
5. Double Vision or Eye Teaming Problems
Some patients with EDS experience double vision, eye strain, headaches with reading, or difficulty keeping their place while reading. This can be related to eye alignment problems, strabismus, or binocular vision dysfunction.
A routine eye chart test may not fully evaluate how the eyes work together, so patients with symptoms may need a binocular vision evaluation.
6. Retinal Concerns
The retina is the light-sensitive tissue in the back of the eye. Some forms of EDS and related connective tissue disorders have been associated with increased concern for retinal problems, including retinal tears or retinal detachment, especially in patients with high myopia or abnormal vitreous changes.
Symptoms that should be treated as urgent include:
New flashes of lightA sudden increase in floatersA curtain, shadow, or missing area in visionSudden vision lossNew distortion or severe blurred vision
These symptoms should be evaluated promptly, often the same day.
Why Eye Surgery Requires Extra Caution
EDS can make tissues more fragile and healing less predictable. This matters for procedures involving the cornea, sclera, eyelids, retina, glaucoma, or cataracts. Patients with EDS should tell their eye doctor and surgeon before any eye procedure, including LASIK, cataract surgery, retinal surgery, eyelid surgery, or glaucoma laser treatment.
This does not mean patients with EDS can never have eye surgery. It means the surgeon may need to take extra precautions, carefully evaluate tissue thickness and healing risk, and choose the safest approach. Studies and clinical reviews have reported surgical considerations and complications in some EDS patients, especially depending on EDS subtype and procedure type.
What Should an Eye Exam Include?
For a patient with Ehlers-Danlos syndrome, an eye exam may include:
A careful glasses prescription checkDry eye evaluationEye pressure measurementSlit lamp exam to check the cornea, sclera, eyelids, and lensDilated retinal examCorneal topography if keratoconus or corneal thinning is suspectedBinocular vision testing if there is double vision, headaches, or eye strainDiscussion of surgical risk before any eye procedure
Not every patient needs every test at every visit, but the exam should be guided by symptoms, EDS subtype, family history, and prior eye findings.
When Should Patients With EDS See an Eye Doctor?
Patients with EDS should consider regular comprehensive eye exams, especially if they have dry eye symptoms, high prescriptions, changing vision, double vision, light sensitivity, a history of retinal problems, or plans for eye surgery.
Seek urgent eye care for sudden flashes, new floaters, a curtain in the vision, sudden vision loss, eye trauma, or severe eye pain.
The Bottom Line
Ehlers-Danlos syndrome can affect more than joints and skin. Because the eyes rely on collagen and connective tissue, EDS may be associated with dry eye, myopia, corneal changes, blue sclera, double vision, and retinal concerns. Most eye issues can be monitored or treated, but early detection is important.
For patients with EDS, the goal is not to worry—it is to be proactive. A comprehensive eye exam can help identify risks early, protect vision, and guide safe treatment decisions.
