Atopic Keratoconjunctivitis
What Is Atopic Keratoconjunctivitis?
If you have severe eczema, your immune system overreacts to substances that are usually harmless. This same immune response can affect your eyes, leading to AKC. The inflammation that affects your skin can also attack the delicate tissues around and inside your eyes.
Ocular symptoms are common in atopic dermatitis. True atopic keratoconjunctivitis affects a subset of adults with moderate to severe atopic dermatitis, and reported rates vary widely by study. The eye inflammation often appears years after your skin condition begins, typically during your late teens or twenties.
AKC causes symptoms that can significantly impact your daily life and comfort. You may notice these problems throughout the year, not just during certain seasons.
- Intense itching of the eyes and eyelids that may worsen at night
- Burning or stinging sensations in your eyes
- Thick, stringy mucus discharge
- Redness and swelling of the eyelids and eye surface
- Sensitivity to light that makes it hard to be outdoors or in bright rooms
Avoid rubbing your eyes, since rubbing can worsen inflammation and increases the risk of corneal damage.
Unlike seasonal allergic conjunctivitis that affects millions of people each spring and summer, AKC is present year-round and involves both your conjunctiva and cornea. Seasonal allergies typically cause mild redness and itching that goes away on its own or with simple over-the-counter drops.
AKC is much more severe and can damage your cornea, potentially leading to scarring and vision loss. The eyelid involvement is also more pronounced in AKC, with thick, scaly skin on the lids that resembles the eczema patches on other parts of your body. Keratoconus, a progressive corneal thinning often linked to chronic eye rubbing, is more commonly associated with atopy and requires early detection.
Some symptoms mean you need to see our eye doctor right away, even if you have a scheduled appointment coming up soon. These urgent warning signs suggest that your condition may be getting worse or that a serious complication has developed.
- Sudden decrease in your vision or blurry vision that does not clear with blinking
- Severe eye pain that interferes with your normal activities
- Extreme sensitivity to light that forces you to stay in dark rooms
- Feeling like something is scratching your eye with every blink
- Discharge that is yellow or green and very thick
- New eye pain and light sensitivity or a sudden drop in vision while using steroid eye drops
Without proper treatment, AKC can lead to several serious problems that may permanently damage your eyesight. The chronic inflammation puts stress on multiple parts of your eye over time.
Additional complications to watch for:
- Keratoconus, a progressive thinning and bulging of the cornea that can be worsened by eye rubbing
- Herpes simplex keratitis, which can be more frequent in people with atopic disease and is made worse by steroid drops
- Eyelid and conjunctival scarring that can lead to misdirected lashes and chronic irritation
Repeated inflammation can cause scarring of your cornea, making it cloudy instead of clear. You may also develop cataracts at a younger age than most people, often in your thirties or forties rather than your sixties or seventies. Additionally, the long-term use of steroid eye drops, which are sometimes needed to control severe flare-ups, can increase your risk of developing glaucoma and cataracts. We also look for corneal ulcers. Shield ulcers are more typical of vernal keratoconjunctivitis but can occur in long-standing AKC.
Who Is at Risk for Atopic Keratoconjunctivitis?
Having atopic dermatitis is the single biggest risk factor for developing AKC. The more severe your eczema, the higher your chances of experiencing eye involvement. People with mild, occasional eczema rarely develop AKC.
If your eczema affects your face and eyelids, you face an even greater risk. The skin inflammation around your eyes can spread to the eye surface itself, triggering the chronic allergic response that defines AKC.
Many people with AKC have what doctors call the atopic triad, which means they have three related allergic conditions. Along with atopic dermatitis, these individuals also suffer from asthma and hay fever (allergic rhinitis).
- Asthma or a history of wheezing, especially if it started in childhood
- Seasonal or year-round allergic rhinitis with sneezing and congestion
- Food allergies, particularly to common triggers like eggs, milk, or nuts
- A family history of any of these allergic conditions
While AKC is always present to some degree, certain exposures can make your symptoms flare up and become more uncomfortable. Identifying your personal triggers helps you manage the condition more effectively.
- Dust mites in bedding, carpets, and upholstered furniture
- Pet dander from cats, dogs, or other furry animals
- Pollen during high-count days in spring and fall
- Smoke from cigarettes, fires, or cooking
- Strong fragrances in perfumes, cleaning products, or air fresheners
AKC most commonly appears in young adults, usually between the ages of 20 and 50. However, symptoms can begin in your teenage years if you have had severe eczema since early childhood. The condition affects men more often than women, though we do not fully understand why this pattern exists.
Symptoms often fluctuate over the years, with some periods being worse than others. Many people find that their AKC remains active for decades, requiring ongoing management throughout much of their adult life.
How We Diagnose Atopic Keratoconjunctivitis
When you come in with symptoms that might be AKC, we start by asking detailed questions about your medical history, especially any skin conditions or allergies you have. We want to know when your symptoms started, what makes them better or worse, and how they affect your daily activities.
We then examine the skin around your eyes and your eyelids carefully, looking for the thick, scaly patches that are typical of eczema. We also look for signs that you have been rubbing your eyes frequently, such as darkened skin on the eyelids or loss of eyelashes.
We use a special microscope called a slit lamp to examine your eye surface in detail. This instrument shines a narrow beam of bright light into your eye, allowing us to see the conjunctiva, cornea, and other structures at high magnification.
- Checking for inflammation, redness, and swelling of the conjunctiva
- Looking at the blood vessels in the white part of your eye to assess inflammation
- Examining the area where your upper eyelid meets your eye for papillae (small bumps)
- Inspecting your tear film and the quality of your tears
- Everting the upper eyelid to examine the tarsal conjunctiva for papillae
- Measuring tear production when indicated, such as with a Schirmer test
- Ordering corneal topography or tomography if keratoconus is suspected
To see if your cornea has been damaged by chronic inflammation, we place a special orange dye called fluorescein in your eye. This dye is harmless and temporarily stains any areas where the outer layer of your cornea has been worn away or damaged. When we shine a blue light on your eye, these damaged areas glow bright green.
We also look for other corneal changes that can occur with long-standing AKC, such as scarring, blood vessels growing into the normally clear cornea, or corneal ulcers. If we find significant corneal involvement, we may need to monitor you more closely and adjust your treatment plan. If we suspect early keratoconus, we will perform corneal topography or tomography to map corneal shape and detect early changes.
We evaluate how severe your AKC is by looking at multiple factors together. The severity determines how aggressively we need to treat your condition and how often you need follow-up visits.
Mild cases have limited redness and itching with no corneal involvement. Moderate cases show more inflammation, persistent symptoms, and early corneal changes like punctate (tiny) damage. Severe cases involve significant corneal scarring, vision loss, or complications like cataracts.
Several other conditions can cause red, itchy eyes, so we need to make sure we have the correct diagnosis. We check for infections like bacterial or viral conjunctivitis, which require different treatments. We also rule out other forms of allergic eye disease, such as vernal keratoconjunctivitis, which affects younger people and has seasonal patterns.
- Checking for signs of blepharitis (eyelid inflammation from other causes)
- Testing your eye pressure to detect any glaucoma
- Examining the lens inside your eye for early cataract formation
- Looking for signs of dry eye disease, which often occurs alongside AKC
Treatment Options for Atopic Keratoconjunctivitis
One of the most important treatments for AKC is using artificial tears frequently throughout the day. These lubricating drops wash away allergens from your eye surface, dilute inflammatory substances in your tears, and provide a protective coating over your cornea. We typically recommend preservative-free artificial tears if you need to use them more than four times a day, ideally in single-use vials.
You can use these drops as often as you need, even every hour if your eyes feel dry or irritated. Many of our patients find that keeping a bottle of artificial tears with them at all times helps prevent symptoms from becoming severe. Use single-use vials for very frequent dosing to reduce preservative toxicity and bottle contamination.
Antihistamine eye drops work by blocking the histamine that your body releases during an allergic reaction. These drops can quickly reduce itching and redness when you use them at the first sign of symptoms. Mast cell stabilizers work differently by preventing your immune cells from releasing histamine and other inflammatory substances in the first place.
Some newer eye drops combine both an antihistamine and a mast cell stabilizer in one bottle, giving you both immediate relief and longer-term prevention. We may recommend using these drops two to four times daily, depending on how severe your symptoms are. Avoid over-the-counter redness-relief decongestant drops, which can cause rebound redness and dryness.
When your AKC flares up severely, we may prescribe steroid eye drops to quickly reduce inflammation. These powerful medications can dramatically improve your symptoms within a few days. However, steroids carry risks when used long-term, including increased eye pressure and cataract formation.
We use steroid drops only for short periods during severe flare-ups, then taper the dose gradually as your symptoms improve. We will monitor your eye pressure closely if you need steroid drops, checking it at regular intervals to catch any increases early. We typically check your eye pressure within 2 to 4 weeks of starting a steroid and at intervals afterward. Do not use leftover steroid drops or someone else's prescription. If infection is suspected, especially herpes simplex keratitis, we avoid steroids and treat the infection first.
For ongoing control of AKC without the risks of long-term steroids, we may recommend immunomodulator eye drops. These medications include cyclosporine eye drops and off-label topical tacrolimus, which is often used as an eyelid ointment or as compounded ophthalmic drops. They suppress the overactive immune response in your eyes without raising eye pressure or causing cataracts. They work well for maintaining control once we have gotten your symptoms under better management.
Immunomodulator drops typically take several weeks to reach their full effect, so you need to be patient and use them consistently. Some people experience mild burning or stinging when they first start these drops, but this usually improves after a few weeks of use.
If your AKC is very severe or does not respond well to eye drops alone, we may work with your primary care doctor or allergist to add oral medications. Oral antihistamines can help control the overall allergic response in your body, potentially reducing eye symptoms as well.
- Non-sedating antihistamines taken once daily for general allergy control
- Short courses of oral steroids for severe flare-ups that do not respond to eye drops
- Oral immunosuppressive medications in rare cases of treatment-resistant AKC
- If significant blepharitis or meibomian gland dysfunction is present, we may add short courses of topical antibiotic ointment or oral medications such as doxycycline
Biologic medications target specific parts of the immune system involved in allergic inflammation. Dupilumab, a biologic approved for moderate to severe atopic dermatitis, may help some people with AKC by reducing systemic type 2 inflammation. Use for AKC is off-label.
Dupilumab can also cause or worsen eye inflammation in some patients. If a biologic is used, we coordinate closely with your dermatologist and monitor your eyes for side effects.
Other systemic options we may discuss with your dermatologist or allergist for refractory disease:
- Omalizumab (anti-IgE) for selected severe allergic disease
- JAK inhibitors used for atopic dermatitis that may improve ocular symptoms when skin disease is controlled
These medications are given as injections, usually every two weeks, and may produce significant improvement in both your skin and eye symptoms over several months. Because biologics are expensive and require ongoing injections, we typically reserve them for people with severe, difficult-to-control disease.
When AKC leads to serious corneal or eyelid complications, we may recommend procedures to preserve your vision and comfort. These are typically performed by a cornea specialist.
- Superficial debridement of corneal plaques or shield-like lesions plus bandage contact lenses and topical antibiotics
- Amniotic membrane grafts or resection of large tarsal papillae in refractory disease, performed by a cornea specialist
- Punctal occlusion in severe ocular surface dryness to improve tear retention
- Corneal collagen cross-linking to halt progression of keratoconus when indicated
- Corneal transplantation for visually significant scarring or thinning that does not respond to other treatments
Managing AKC at Home
Keeping a symptom diary can help you identify what makes your AKC worse. Write down when your symptoms flare up and what you were exposed to in the hours or days before. Over time, patterns may emerge that point to specific triggers you can avoid.
Once you know your triggers, take steps to minimize exposure. If dust mites worsen your symptoms, use allergen-proof covers on your pillows and mattress, wash bedding in hot water weekly, and reduce clutter where dust can accumulate. If pet dander is a problem, keep pets out of your bedroom and wash your hands after touching them.
Applying a clean, cool washcloth to your closed eyelids for 5 to 10 minutes several times a day can provide significant relief from itching and reduce swelling. The cool temperature helps calm inflammation and gives you a safe way to soothe your eyes without rubbing them.
- Use a freshly laundered washcloth each time to avoid introducing bacteria
- Soak the cloth in cool (not ice-cold) water and wring out excess moisture
- Place the compress gently over your closed eyelids
- Avoid rubbing your eyes, even with the compress in place
Regular eyelid hygiene removes inflammatory debris, allergens, and bacteria from your eyelid margins and lashes. This simple step can reduce irritation and make your other treatments work better. We recommend cleaning your eyelids once or twice daily, especially if you notice crusting or debris on your lashes.
Use a gentle, fragrance-free eyelid cleanser or preservative-free lid wipes on a clean cotton pad or your fingertip. Avoid baby shampoo, which can irritate the ocular surface and destabilize the tear film. Close your eye and gently massage the eyelid margin and base of the lashes, then rinse thoroughly with lukewarm water. Pat your eyelids dry with a clean towel.
For eczema of the eyelids, your dermatologist may recommend nonsteroidal calcineurin inhibitor creams, such as tacrolimus or pimecrolimus, to limit steroid exposure near the eye. Avoid chronic use of potent steroid creams on the eyelids because they can increase the risk of glaucoma and cataracts.
Wearing contact lenses when you have active AKC is generally not recommended. Contact lenses can trap allergens against your eye surface and make inflammation worse. The lenses can also become coated with mucus and protein deposits more quickly when your eyes are inflamed, leading to discomfort and poor vision.
If your AKC is well controlled and you really want to wear contacts, talk with us first. We can help you decide if it is safe and, if so, recommend daily disposable lenses that you throw away each night, reducing the buildup of deposits and allergens. Avoid all contact lenses during active flares. If you have corneal irregularity such as keratoconus, rigid gas permeable or scleral lenses may be considered once your eyes are quiet, and must be fit and monitored by a specialist. Do not wear contact lenses while using steroid eye drops.
Making your home environment as allergen-free as possible helps reduce the overall burden on your immune system. Focus on your bedroom first, since you spend many hours there each night.
- Remove carpeting and use hardwood or tile floors that are easier to keep dust-free
- Use a HEPA air purifier in your bedroom and other rooms where you spend time
- Keep windows closed during high pollen days and use air conditioning instead
- Vacuum frequently with a HEPA-filter vacuum cleaner
- Avoid down pillows and comforters, which can harbor dust mites and mold
Long-Term Care and Monitoring
The frequency of your follow-up visits depends on how severe your AKC is and how well it is controlled with treatment. If you have mild AKC that is well managed, we may see you every 6 to 12 months. However, if your condition is moderate to severe, or if you are using steroid eye drops, we will want to see you much more frequently, perhaps every 1 to 3 months.
During these visits, we recheck your eye surface for signs of improvement or worsening inflammation, measure your eye pressure, and examine your cornea for any new damage. These regular exams allow us to adjust your treatment plan as needed and catch complications early.
Because AKC itself and the steroid medications used to treat it both increase your risk of cataracts and glaucoma, we screen for these conditions at every visit. We measure your eye pressure with a quick, painless test and examine the lens inside your eye for any clouding that might indicate early cataract formation.
If we detect increased eye pressure or early cataracts, we change your treatment plan to minimize further risk. This might mean reducing or stopping steroid drops and switching to other medications, or scheduling more frequent monitoring visits. We also ask about and review any steroid creams used on the eyelids, since long-term periocular steroids can raise eye pressure and increase cataract risk.
At each visit, we carefully examine your cornea for signs of new damage or progression of existing problems. Early detection of corneal issues allows us to treat them before they cause permanent scarring or vision loss. We look for areas of thinning, new blood vessel growth, or the formation of corneal ulcers.
- Repeating fluorescein staining to check for surface damage
- Measuring corneal thickness if we are concerned about thinning
- Taking photographs to document changes over time
- Referring you to a cornea specialist if severe complications develop
- Corneal topography or tomography to detect early keratoconus and monitor progression
- Early procedural care when needed, such as superficial debridement of plaques with a bandage contact lens and topical antibiotics, or amniotic membrane for persistent epithelial defects
You should contact our office right away if you notice any sudden changes in your vision or if your symptoms become much worse despite following your treatment plan. Do not wait until your next scheduled appointment if you develop severe pain, significant vision loss, or intense light sensitivity that keeps you from going about your normal activities.
Also call us if you have been using steroid eye drops and notice halos around lights, eye pain, or headaches, as these can be signs of elevated eye pressure. If you develop a fever along with eye discharge and redness, you may have an infection that needs immediate attention.
Managing AKC works best when your eye doctor, dermatologist, and allergist communicate with each other about your care. Your dermatologist manages your skin eczema, which often improves your eye symptoms as well. Your allergist can help identify specific triggers through allergy testing and may prescribe medications or immunotherapy (allergy shots) to reduce your overall allergic burden.
Let each of your doctors know about medications prescribed by the others, since some treatments can help multiple conditions at once. For example, the biologic medication dupilumab can improve both severe eczema and AKC, making coordination between your dermatologist and eye doctor especially important.
Frequently Asked Questions
Unfortunately, there is no cure for AKC at this time. Like the underlying atopic dermatitis that causes it, AKC is a chronic condition that requires ongoing management. However, with proper treatment and trigger avoidance, most people can control their symptoms well and prevent vision-threatening complications. Some individuals find that their symptoms become less severe over time, especially as they learn to manage their triggers effectively.
Many people with AKC notice that their symptoms gradually become less severe as they age, particularly after age 50. This improvement often mirrors what happens with the underlying eczema, which also tends to become milder in later adulthood. However, any corneal scarring or vision loss that occurred during active disease will not improve on its own, which is why early and consistent treatment is so important.
You can wear eye makeup if your AKC is well controlled, but you need to be very careful about what products you use and how you apply them. Choose fragrance-free, hypoallergenic makeup specifically labeled for sensitive eyes. Replace your eye makeup every three months to prevent bacterial buildup, and never share makeup with others. Remove all eye makeup thoroughly each night before bed using a gentle, tear-free makeup remover. If you notice that certain products make your symptoms worse, stop using them immediately.
Most eye doctors advise against wearing contact lenses during active AKC flare-ups because they can make inflammation worse and increase your risk of corneal complications. However, if your condition is very well controlled with treatment and you have no corneal damage, we may allow daily disposable soft contact lenses. Never sleep in your lenses, and remove them immediately if your eyes become red, painful, or uncomfortable.
While both AKC and vernal keratoconjunctivitis (VKC) are severe forms of allergic eye disease, they affect different age groups and follow different patterns. VKC typically occurs in children and young individuals, often boys living in warm climates, and usually improves after puberty. The symptoms follow a seasonal pattern, worsening in spring and summer. AKC, in contrast, affects adults with atopic dermatitis, persists year-round, and often continues for decades without spontaneous improvement.
Allergic conditions including atopic dermatitis and AKC do run in families, but having AKC does not mean your children will definitely develop it. If you have AKC and your partner also has allergic conditions, your children face a higher risk of developing eczema, asthma, hay fever, or related problems. However, many children with atopic dermatitis never develop AKC. If your child has eczema, watch for signs of eye involvement like persistent redness, itching, or rubbing, and bring them in for an eye exam if you notice these symptoms.
Getting Help for Atopic Keratoconjunctivitis
If you have atopic dermatitis and are experiencing persistent eye redness, itching, or irritation that lasts beyond a few days, schedule an appointment with our eye doctor for a comprehensive evaluation. Early diagnosis and treatment can prevent serious complications and preserve your vision for years to come. We will work with you to develop a personalized treatment plan that controls your symptoms and fits into your lifestyle.
