Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis (SJS/TEN) and Ocular Involvement
Understanding Stevens-Johnson Syndrome and Your Eyes
Stevens-Johnson Syndrome is a severe immune-mediated hypersensitivity reaction that affects your skin and mucous membranes, including the delicate tissues of your eyes. The condition causes widespread inflammation and tissue damage throughout the body. Most cases are triggered by certain medications, though infections can sometimes be the cause.
SJS and toxic epidermal necrolysis are part of a spectrum of disease defined by how much body surface area is affected. When SJS affects the eyes, it targets the surface tissues like the conjunctiva and cornea. Eye involvement happens in the majority of SJS cases and requires specialized care to prevent permanent damage.
During an SJS episode, your immune system attacks the cells that line your eye surface. This reaction causes the protective outer layers to break down and peel away. The result is raw, exposed tissue that becomes inflamed and painful.
The damage can destroy important structures on your eye surface, including the glands that make tears and the stem cells that help your cornea heal. Without proper treatment, scarring between the eyelid and eyeball can develop, creating permanent complications.
Eye symptoms typically appear within the first few days of an SJS episode, often alongside skin and mouth problems. The acute phase of eye damage usually lasts one to three weeks. During this critical window, aggressive eye care is essential to limit tissue destruction.
After the acute phase ends, the healing process begins but can take months. Some eye complications may not become apparent until weeks or even years after the initial episode. This delayed timeline makes long-term follow-up care crucial for all SJS survivors.
The first few days and weeks of SJS determine how much permanent eye damage will occur. Early intervention by an eye doctor can reduce scarring, preserve tear production, and protect your vision. Delays in treatment often lead to complications that are much harder to manage later.
We focus on keeping the eye surface moist, preventing the eyelids from sticking to the eyeball, and controlling inflammation. These steps taken early can make the difference between good visual recovery and permanent impairment.
Recognizing Eye Symptoms and Warning Signs
The earliest eye symptoms of SJS often include redness, burning, and a gritty feeling in both eyes. Your eyes may water excessively or produce thick discharge. Light sensitivity is common and can be quite severe, making it difficult to keep your eyes open in normal lighting.
- Red, bloodshot eyes that worsen quickly
- Burning or stinging sensations
- Feeling like sand or grit is in your eyes
- Excessive tearing or sticky discharge
- Difficulty opening your eyes in light
As SJS progresses into its acute phase, the eye surface begins to break down visibly. You may notice white or yellowish membranes forming over the white part of your eye and inside your eyelids. The skin of your eyelids may blister, peel, or become crusty.
Vision can become blurry during this phase due to surface damage and inflammation. Your eyelids may swell so much that opening your eyes becomes difficult. These severe symptoms require immediate medical attention and specialized eye care.
If you develop eye symptoms while experiencing a skin rash, mouth sores, or fever, seek emergency care immediately. SJS is a medical emergency that requires hospitalization. If you develop a widespread rash plus mouth sores, genital sores, eye pain, or fever, go to the emergency department immediately.
Your medical team should involve an eye doctor right away, even if your eye symptoms seem mild at first. Do not wait to see if symptoms improve on their own. The window for preventing permanent eye damage is very short. Emergency eye care should begin as soon as SJS is suspected, not after the diagnosis is confirmed.
Weeks to months after recovering from SJS, you may develop new eye problems or notice worsening symptoms. These late complications signal that scarring or chronic inflammation is affecting your eye health. Common signs include persistent dryness, worsening vision, or a feeling that your eyelashes are rubbing against your eye.
- Chronic dry, gritty eyes despite using artificial tears
- Gradual vision decline or increased blurriness
- Eyelashes turning inward and touching the eye
- Difficulty opening your eyes fully
- Cloudy or hazy areas on the cornea
- Eyelid margin keratinization causing scratchy friction on the cornea
- Symblepharon progression or ankyloblepharon
- Recurrent corneal erosions or filamentary keratitis
- Persistent photophobia or pain not relieved by lubrication
What Causes SJS and Who Is at Risk
Certain medications are responsible for most cases of Stevens-Johnson Syndrome. Antibiotics, especially sulfonamides, and anti-seizure medications are among the most common triggers. Some pain relievers and gout medications also carry a higher risk. The risk is highest within the first two to eight weeks after starting the drug, especially with rapid titration for some anticonvulsants.
- Sulfonamide antibiotics and related drugs
- Anti-seizure medications like lamotrigine and carbamazepine
- Allopurinol for gout treatment
- Some non-steroidal anti-inflammatory drugs
- Certain antibiotics including penicillins and quinolones
While medications cause the majority of SJS cases, infections can also trigger the syndrome. Viral and bacterial infections, including herpes simplex, mycoplasma pneumonia, and HIV, have been associated with SJS. In some cases, no clear trigger can be identified despite thorough investigation.
If you develop a rash or mouth sores while taking a new medicine, seek urgent medical care. Do not restart the suspected drug.
Anyone can develop Stevens-Johnson Syndrome, but certain factors increase your risk. People with weakened immune systems, including those with HIV or lupus, face higher odds. A previous episode of SJS also increases your risk if you are re-exposed to the trigger.
Women appear to develop SJS slightly more often than men. The condition can occur at any age but is somewhat more common in adults than in children. People taking multiple medications simultaneously may also face increased risk.
Your genes play a role in determining whether you will react to certain medications with SJS. Specific genetic markers make some individuals much more likely to develop the syndrome when exposed to particular drugs. Genetic testing before starting high-risk medications may be recommended in specific cases, especially for people of certain ethnic backgrounds.
- HLA-B1502 before carbamazepine or oxcarbazepine in many East and Southeast Asian ancestries
- HLA-A3101 in some populations before carbamazepine
- HLA-B5801 before allopurinol in several Asian and some non-Asian ancestries
- HLA-B5701 before abacavir
Testing is used selectively and does not replace clinical vigilance. If you have a family member who experienced SJS, inform your doctors before starting any new medication. While SJS itself is not inherited, the genetic susceptibility to certain drug reactions can run in families.
How We Diagnose Eye Involvement in SJS
When we examine your eyes during or after an SJS episode, we carefully assess every part of your eye surface and eyelids. We look for signs of membrane formation, tissue breakdown, and scarring. The examination includes checking your vision, eye pressure, and the health of your cornea and conjunctiva.
We also evaluate your tear production and quality, since SJS often damages the glands that keep your eyes moist. Using a specialized microscope called a slit lamp, we can see fine details of the damage and track how your eyes are healing over time.
Beyond the standard eye exam, we may perform several specialized tests to fully understand the extent of eye involvement. These tests help us plan your treatment and predict which complications you might face later. Most of these tests are quick and cause little to no discomfort.
- Tear film evaluation to measure dryness severity
- Schirmer or tear meniscus assessment to quantify tear production
- Corneal staining to reveal areas of surface damage
- Conjunctival impression cytology to assess tissue health
- Photography to document your eye condition over time
We use standardized grading systems to classify how severely SJS has affected your eyes. These grades range from mild surface inflammation to severe scarring and corneal damage. The initial grade helps us determine how aggressive your treatment needs to be during the acute phase.
Grading also gives us a baseline to track your progress during recovery. We reassess the severity at each follow-up visit to identify any worsening or improvement. This information guides our decisions about stepping up or continuing current treatments, including escalation to measures like amniotic membrane, symblepharon rings, and inpatient frequency of care.
SJS affects multiple body systems, so your eye care must be coordinated with your other doctors. We work closely with dermatologists, hospitalists, and intensive care teams during the acute phase. This collaboration ensures that treatments for your skin and overall condition do not interfere with protecting your eyes.
Early systemic immunomodulatory therapy decisions are made by dermatology and critical care teams and may influence ocular outcomes. We ensure the culprit drug is documented in your medical record and provide clear allergy documentation to prevent re-exposure. We provide regular updates to your medical team about your eye status and any treatments we prescribe. Your other doctors share information about medications and therapies that might affect your eyes. This teamwork approach gives you the best chance of preserving your vision while treating the whole disease.
Treatment Options for SJS Eye Complications
During the acute phase of SJS, preserving your eye surface is our top priority. We use intensive lubrication with preservative-free artificial tears and ointments, often applied every hour or even more frequently. Removing inflammatory membranes from your eye surface may be necessary to prevent scarring.
We take steps to prevent your eyelids from sticking to your eyeball, a complication called symblepharon. This may involve using special devices or materials to keep the surfaces separated while they heal. Standard acute-phase measures include:
- Early placement of self-retaining amniotic membrane for moderate to severe ocular surface involvement, ideally within the first three to seven days
- Use symblepharon rings or conformers to keep the fornices open
- Daily gentle removal of pseudomembranes and sweeping of fornices to prevent adhesions
- Use only preservative-free formulations whenever possible
- Avoid sulfonamide-containing topical antibiotics if a sulfonamide drug triggered SJS
Aggressive treatment during these first weeks can prevent many long-term complications.
We may prescribe several types of eye drops and medications to control inflammation and support healing. Preservative-free artificial tears are used very frequently to keep the eye surface moist. Antibiotic drops or ointments help prevent infection in the damaged tissue.
- Preservative-free artificial tears for intensive lubrication
- Non-sulfa prophylactic antibiotic ointment to reduce infection risk in denuded epithelium
- Topical corticosteroids may be used early under specialist supervision to control inflammation and reduce scarring risk. Dosing and taper are individualized.
Autologous serum or platelet-derived drops are typically introduced in the subacute or chronic phase.
Amniotic membrane transplantation involves placing a thin layer of tissue from human placenta onto your eye surface. This biological bandage reduces inflammation, promotes healing, and may help prevent scarring. We may recommend this treatment during the acute phase if you have severe surface damage.
The procedure is typically performed in an operating room or sometimes at the bedside if you are hospitalized. Self-retaining devices allow bedside placement in hospitalized patients and are most effective when placed early. The membrane dissolves over time as your own tissue heals beneath it. Studies suggest that early use of amniotic membrane may improve long-term outcomes in severe SJS eye involvement.
Many SJS survivors develop chronic dry eye that lasts for years or permanently. Managing this condition requires a multi-layered approach tailored to your specific needs. In addition to frequent artificial tears, we may recommend several evidence-based therapies:
- Punctal occlusion or cautery to retain tears
- Moisture chamber eyewear and home humidification
- Scleral lenses, including PROSE devices, once the surface is stable and fit by specialists
- Topical anti-inflammatory therapies such as cyclosporine or tacrolimus when appropriate
- Autologous serum or platelet-rich plasma drops for severe ocular surface disease
Avoid contact lenses during active disease. Scleral lenses are considered only after stabilization and with specialist guidance. Finding the right combination of therapies often takes time and adjustment.
If scarring causes complications like inward-turning eyelashes, blocked tear drainage, or eyelid abnormalities, surgery may be necessary. Procedures to correct these problems include removing misdirected lashes, reconstructing the eyelid margin, or releasing scar tissue between the eyelid and eyeball. These surgeries aim to improve comfort and protect the cornea from further damage.
- Mucous membrane grafting to treat eyelid margin keratinization and restore a smooth lid margin
- Fornix reconstruction with mucous membrane grafts for symblepharon
- Permanent punctal cautery for severe aqueous deficiency
- Tarsorrhaphy in cases of exposure or recurrent epithelial breakdown
- Limbal stem-cell-based ocular surface reconstruction when feasible; keratoprosthesis types selected by surface wetness
For severe corneal scarring that causes vision loss, corneal transplantation may be considered in specific cases. However, SJS-damaged eyes have lower success rates with standard transplants due to poor tear production and inflammation.
Recovery and Long-Term Eye Care
Healing from SJS eye involvement is a gradual process that unfolds over many months. During the first few weeks after the acute phase, you will likely still have significant redness, discomfort, and light sensitivity. These symptoms should slowly improve, though progress may feel frustratingly slow at times.
Complete healing of the eye surface can take three to six months or longer. Some symptoms, particularly dryness, may never fully resolve and require ongoing management. We monitor your healing closely during this period to catch any complications early and adjust your treatment as needed.
Your daily eye care routine at home is crucial for long-term success. Use your prescribed eye drops and medications exactly as directed, even when your eyes feel better. Keeping your eyes well-lubricated throughout the day prevents further damage to the healing surface.
- Apply preservative-free artificial tears at least four to six times daily or as prescribed
- Use thick ointment in your eyes at bedtime to prevent overnight drying
- Wear wraparound sunglasses outdoors to reduce light sensitivity and protect against wind
- Keep your eyelids clean using warm compresses and gentle cleansing if directed
- Avoid smoke, dust, and other irritants that can worsen symptoms
- Use only preservative-free eye drops unless your doctor advises otherwise
- Use a home humidifier and moisture chamber glasses to reduce evaporation
- Do not use over-the-counter redness relievers or topical anesthetics
- Avoid rubbing your eyes
- Do not wear contact lenses unless your eye doctor has cleared you, and only as directed
We will want to see you frequently during the first few months after SJS. Initial follow-up visits may be weekly or even more often during the acute phase. As your eyes stabilize, we gradually space appointments further apart, but you will likely need to be seen at least every few months for the first year.
Call sooner for worsening pain, light sensitivity, decreased vision, or increased discharge. Even after you achieve stable healing, we recommend ongoing eye exams at least once or twice yearly for life. These long-term visits help us detect late complications early and adjust your care to maintain the best possible vision and comfort.
Protecting your vision after SJS requires lifelong attention and care. Always keep a list of medications or other triggers that caused your SJS episode and share this with every healthcare provider you see. Avoid re-exposure to the trigger, as this could cause another episode with potentially worse eye damage.
Stay vigilant for changes in your eye comfort or vision and report them promptly. Maintain your daily eye care routine even when symptoms are minimal. With proper ongoing care, many SJS survivors maintain functional vision and good quality of life despite the challenges this condition presents.
Frequently Asked Questions
Yes, SJS can lead to permanent vision loss, especially if eye care is delayed or the initial damage is severe. However, with prompt treatment and careful long-term management, many people maintain good functional vision. The degree of permanent impairment varies widely depending on the severity of acute damage and how well late complications are controlled.
Most people who experience eye involvement with SJS need some level of ongoing eye care for the rest of their lives. This typically includes daily use of artificial tears, regular eye doctor visits, and monitoring for late complications. The intensity of care you need may decrease over time, but periodic check-ups remain important even years after your initial episode.
Yes, specialized scleral lenses, including PROSE devices, can help some SJS survivors. These large-diameter lenses vault over the damaged cornea and rest on the white part of the eye. They can improve vision in scarred eyes and provide a reservoir of moisture for severe dry eye. Meticulous hygiene and specialist fitting are required. Not everyone is a candidate, but our eye doctor can evaluate whether these lenses might benefit you. Prosthetic lenses for cosmesis are a different option and are used for appearance rather than ocular surface disease.
SJS can recur if you are exposed again to the medication or trigger that caused your first episode. A second episode often causes even more severe damage than the first. This is why strictly avoiding your known trigger is critical. We provide documentation of your trigger to help you and your medical providers prevent accidental re-exposure.
You should see an eye doctor as soon as SJS is suspected, ideally within the first 24 to 48 hours of symptoms. Early involvement of an eye specialist significantly improves your chances of minimizing permanent eye damage. If you are hospitalized for SJS, request an eye doctor consultation immediately, even if your eye symptoms seem minor compared to your other problems.
They can be beneficial early when prescribed and monitored by an eye specialist. Topical corticosteroids may help control inflammation and reduce scarring risk during the acute phase. Never start or stop them on your own. Your eye doctor will determine the appropriate dosing and taper based on your individual needs.
Seek urgent care immediately. In suspected SJS, the culprit drug is stopped promptly under medical supervision. A rash combined with mouth sores, genital sores, or fever is a medical emergency. Do not restart any suspected medication without clearance from your medical team.
