Keratoconjunctivitis: symptoms, causes and treatment of inflammation of the cornea and conjunctiva
Keratoconjunctivitis often disguises itself as a simple eye irritation, and that's where its insidiousness lies. In reality, it's a simultaneous inflammation of the cornea and conjunctiva, which can affect vision. Its causes vary, so choosing treatment at random is dangerous.
We'll explain how to recognize the disease, how it differs from similar conditions, and how we help patients.

Why does keratoconjunctivitis occur?
The causes of keratoconjunctivitis are divided into several groups. The choice of treatment directly depends on these causes. Let's look at the main ones.
Viral and bacterial causes
Inflammation is often caused by viruses, including adenoviruses, and bacteria. The viral form is usually accompanied by profuse lacrimation and redness. Bacterial inflammation is more often accompanied by purulent discharge from the eyes and sticky eyelids.
Allergic keratoconjunctivitis
A reaction to pollen, dust, or other allergens causes allergic rhinitis. It is characterized by severe itching, watery eyes, and swelling. This inflammation often worsens during certain seasons.
Keratoconjunctivitis sicca and tear film disorder
Keratoconjunctivitis sicca is associated with a disruption of the tear film, which moisturizes and protects the surface of the eye. When tears are insufficient, the cornea dries out, causing a burning sensation and a gritty sensation in the eyes. This condition is closely related to dry eye syndrome.
Contact lenses, dry air and visual strain
Inflammation can be triggered by poor lens hygiene, dry air, and prolonged screen time. Contact lenses, if worn incorrectly, can damage the surface of the eye. Therefore, if you experience discomfort, you should temporarily remove your lenses and consult a doctor.
Symptoms of keratoconjunctivitis
The symptoms of keratoconjunctivitis are easily mistaken for simple irritation, so seeking help is often delayed. They vary depending on the type and severity. Let's look at what to look for.
Early signs that are often ignored
First, the eyes become red, with a gritty sensation and mild itching. These are followed by tearing and discomfort when blinking. At this stage, a person often assumes the eye is simply tired.
Signs that require immediate eye contact with an ophthalmologist
Pain, severe photophobia, and decreased vision should raise concern. Profuse purulent discharge and persistent redness are also worrisome. Below are symptoms that require immediate eye contact:
- Eye pain has developed
- Increased photophobia
- Vision has decreased
- Purulent or profuse discharge
- Redness persists for several days
- Symptoms interfere with contact lens wear
If at least one of these signs is present, don't wait: corneal involvement requires an examination.
How does the disease affect vision and quality of life?
Due to corneal involvement, vision may become blurred, especially in bright light. Constant discomfort interferes with work, reading, and wearing lenses. Therefore, treatment should be sought promptly.
How to distinguish keratoconjunctivitis from conjunctivitis and keratitis
These conditions are similar in appearance, but their dangers and treatments differ. A doctor can help you understand them, and below we'll explain the key differences.
Differences in symptoms
Conjunctivitis affects only the mucous membrane, and vision is usually preserved. Keratitis is an inflammation of the cornea with severe pain and photophobia. Keratoconjunctivitis combines the symptoms of both conditions and is therefore more severe.
Why self-diagnosis is dangerous
Similar symptoms with different causes require different treatments. Drops that help with one form of the disease can be harmful for another. Therefore, self-diagnosis often leads to errors and wasted time.
When differential diagnostics is needed
If the inflammation persists, recurs, or is accompanied by pain and decreased vision, a differential diagnosis is necessary. The doctor will determine the type and cause to determine the correct treatment. Without this, treatment will be random.
Keratoconjunctivitis diagnostics in our center
Diagnosing keratoconjunctivitis begins with an examination and collecting complaints. Our goal is to confirm inflammation, assess the condition of the cornea, and find the cause. Let's break down the steps.
- Ophthalmologist examination and patient history First, the ophthalmologist will determine how long ago the symptoms began and what preceded them. Contact with allergens, contact lens wear, and past infections are important. These details help to determine the specific form of the disease.
- Slit lamp examination of the cornea and tear film The primary method is a slit lamp examination under magnification. The doctor assesses the condition of the cornea and conjunctiva, looking for surface defects. Additionally, the tear film is checked, as dry eyes often contribute to inflammation.
- Tests and additional studies, if needed If dry eye is suspected, a Schirmer test is performed, which measures tear production. Sometimes, a sample is taken for analysis to identify the causative agent. The extent of the examination depends on the clinical picture.
Keratoconjunctivitis treatment
How we select therapy depending on the cause
Some treatments are effective for viral conjunctivitis, while others are effective for bacterial and allergic conjunctivitis. For the dry form, moisturizing is paramount. Therefore, a doctor first determines the cause and then prescribes treatment.
Drops, anti-inflammatory and maintenance therapy
Depending on the form, drops with different effects and anti-inflammatory therapy are used as indicated. For dryness, artificial tears are used to protect the surface. All treatments are combined to avoid damaging the cornea.
What you should not do on your own
Do not use hormonal drops or antibiotics without a prescription. Do not continue wearing lenses if you experience pain or redness. Heat and random treatments for infections can also worsen the condition.
How long does recovery take and how is follow-up performed?
The time frame depends on the cause and severity of the inflammation. For some, improvement occurs quickly, while for others, treatment takes longer and requires follow-up. Follow-up examinations show how the cornea is healing.
In our practice, keratoconjunctivitis is most often managed if the patient seeks treatment at the first symptoms. We don't just relieve redness – we also look for the cause of the inflammation, assess the condition of the cornea, and select the appropriate treatment. – Ophthalmologist
Comparison of forms of keratoconjunctivitis
To make it easier to differentiate between the forms, we've summarized their main features in a table. The final conclusion is still made by the doctor after an examination.
| Form | Underlying cause | Typical symptoms | What the doctor does |
|---|---|---|---|
| Viral | Infection | Redness, watery eyes, discomfort | Antiviral and symptomatic therapy |
| Allergic | Reaction to an allergen | Itching, watery eyes, swelling | Antihistamines, eliminating the trigger |
| Dry | Lacric dysfunction Films | Burning, sandy, stinging eyes | Moisturizing drops, correcting the cause |
| Bacterial | Bacterial infection | Discharge, eyelid sticking | Antibacterial therapy as prescribed |

What is keratoconjunctivitis?
The conjunctiva is a thin mucous membrane that covers the white of the eye and the inner surface of the eyelids. The cornea is the transparent front layer through which light passes. When inflammation affects both structures at once, keratoconjunctivitis develops.
Because the cornea is involved, this condition is more serious than a simple inflammation of the mucous membrane. It often affects vision and requires careful diagnosis. Therefore, it is important not to treat it haphazardly, but first to understand the cause.
How does it differ from regular conjunctivitis?
With regular conjunctivitis, only the mucous membrane is inflamed, and vision is usually not affected. When the cornea is involved, the following symptoms appear:
It is the involvement of the cornea that distinguishes keratoconjunctivitis and makes it more dangerous.
What forms of the disease are more common?
The forms are differentiated by cause: viral, bacterial, allergic, and dry. The presentation and treatment depend on the form. A doctor's examination helps determine which form the patient has.
