What ocular rosacea does
Rosacea is best known as a skin condition, with facial redness and flushing. Ocular rosacea is its eye form: a chronic inflammation of the eyelid margins (blepharitis) and the tear film, causing redness, burning, stinging, a gritty feeling, light sensitivity and blurred vision.[1] Dysfunction of the eyelid oil glands (meibomian gland dysfunction, or MGD) is a typical feature.[1]
It’s common. Estimates of how many people with skin rosacea also have eye involvement range from 10% to 50%, and ocular rosacea can occur without skin signs. Eye symptoms don’t always track how severe the skin is.[1]
In more severe or untreated cases, ocular rosacea can involve the cornea, causing keratitis, new blood vessels growing into the cornea, scarring, thinning, and even perforation.[1] Treatment is stepwise: eyelid and skin hygiene, lifestyle changes, and medicines.[1]
How it can affect scleral lens wear
We didn’t find studies of scleral lenses in people with ocular rosacea specifically. What research does show is that the eyelid problems at the heart of rosacea matter for scleral lens wearers in general:
- Eyelid disease is common among wearers. In a study of 49 habitual scleral lens wearers, dilated blood vessels along the lid margin (telangiectasia) were found in 61% of those wearing lenses for ocular surface disease and 19% of those wearing them for an irregular cornea.[2]
- Fogging is linked to the front surface and inflammation. In 48 wearers, fogged vision was associated with poor wetting of the lens’s front surface.[3] In a larger survey, wearers with midday fogging more often reported redness or irritation, which the authors took as a sign that eye surface inflammation may contribute.[4]
So a scleral lens fitted over untreated lid inflammation may fog, film over, or feel irritating. That’s one reason lid treatment usually continues alongside the lens. The blepharitis and MGD page goes into fogging in more detail.
When a scleral lens may help
If rosacea has scarred your cornea and made it uneven, a scleral lens can smooth out the surface for clearer vision, much as it does for other corneal scarring. If you have severe dry eye alongside rosacea, the fluid reservoir can keep the cornea bathed through the day. See severe dry eye.
One point to raise with your fitter: corneal blood vessel growth can be a complication of both rosacea and scleral lens wear. With lenses, it’s mainly linked to low oxygen, inflammation, overwear, and poorly fitting lenses. The review notes that deeper, larger vessels may point to an underlying disease.[5] If rosacea has already caused vessel growth, your fitter will want to watch it at each visit.
Common questions
My skin rosacea is mild. Can my eyes still be affected?
Yes. Eye symptoms don't always match the severity of the skin, and ocular rosacea can occur without obvious skin signs. If your eyes are often red, burning or gritty, ask your eye doctor to check your eyelids.
Should I get my rosacea under control before being fitted?
That's a sensible question to ask your eye doctor. Eyelid inflammation is linked to fogging and irritation through scleral lenses, so many people do better when the lids are being treated. Your doctor can tell you whether your eyes are ready for a fitting.
Will a scleral lens protect my cornea from rosacea?
It may protect the surface from drying and from the rubbing of the eyelids while you wear it, but it doesn't treat the inflammation that drives rosacea. Keep following the treatment plan for your lids and skin.
