Your eyes are made largely of collagen. So when your collagen doesn't behave the way it should, your eyes feel it.
Eye problems in EDS get mentioned occasionally, but rarely broken down by subtype. That's the gap this post is trying to close. Because what's happening in your eyes depends on the type you have, and in some subtypes, it requires serious specialist care.
A 2022 comprehensive review by Asanad et al. in Frontiers in Medicine confirmed that ocular manifestations vary greatly between EDS subtypes and any collagenous structure of the eye can be affected. Full citation in comments. This is the overview. Your subtype has more detail behind it than one post can hold.
What crosses most subtypes
Dry eyes, myopia, and keratoconus occur across multiple EDS types and are worth naming up front because they're frequently missed.
In EDS, scleral collagen changes can reduce the structural resistance of the eye wall, allowing the eyeball to elongate from front to back. This raises the risk of near-sightedness, retinal tears, and retinal detachment. Separately, changes to the vitreous gel inside the eye may also contribute to retinal detachment risk through a different mechanism. Blue sclera appears particularly in cEDS and kEDS/BCS rather than universally.
If you've been shortsighted since childhood and nobody's connected it to your connective tissue, that conversation is worth having.
hEDS and HSD
Dry eye and myopia are the most commonly documented ocular findings here. For some people, untreated dry eye can progress to corneal abrasions or erosions, and in a population with already-compromised connective tissue, that's worth monitoring proactively rather than waiting for symptoms to worsen.
cEDS
Cohort studies have documented drooping eyelids, epicanthal folds, blue sclera, dry eyes, and abnormally slanted eyelid openings in classical EDS. In children, drooping eyelids or epicanthal folds can contribute to amblyopia and strabismus. Both conditions are far more treatable when caught early in childhood, so waiting for a routine check is not the right call here. If your child has cEDS and any of these features are present, ask for paediatric ophthalmology review now.
kEDS (kyphoscoliotic)
Significant ocular risk. Progressive myopia, retinal detachment, and globe fragility are documented features. kEDS has considerable clinical overlap with brittle cornea syndrome, and distinguishing between them requires specialist assessment.
Brittle Cornea Syndrome
One of the 13 recognised subtypes and the most serious ocular picture in the group. Features include extreme corneal thinning, high myopia, blue sclera, progressive keratoconus or keratoglobus, and retinal detachment. Without appropriate ophthalmological management, corneal rupture carries a serious risk of permanent vision loss. Management centres on preventing rupture through protective polycarbonate spectacles, regular corneal monitoring, and assessment for skeletal complications. If you have BCS, ophthalmology is not optional. It is a core part of your care.
vEDS
The eye risk here is vascular rather than structural. Collagen mutations in vascular EDS can cause arterial complications, including carotid-cavernous fistula and cervical artery dissection, that lead to blurred vision or visual field defects. Any sudden visual change in vEDS is an emergency presentation, not a reason to book a routine appointment.
The rarer subtypes
For musculocontractural, spondylodysplastic, periodontal, cardiac-valvular, myopathic, and arthrochalasia EDS, eye-specific research is limited. Ocular involvement has been reported in case literature, even where large studies don't yet exist. If you have a rarer subtype, an ophthalmology referral at diagnosis is reasonable to request, regardless of whether you currently have symptoms. Asanad et al. (2022) found EDS is associated with increased odds of concurrent ocular conditions, supporting referral broadly across subtypes.
If you have EDS and haven't had an ophthalmology review, it's worth requesting one. Tell your optometrist your subtype. Ask specifically about corneal thickness, the length of your eyeball from front to back, and retinal integrity. Standard eye tests don't always measure what matters here.
