Keratitis VS Conjunctivitis

Two eye infections often causing confusion are keratitis and conjunctivitis. While both conditions affect the eyes in similar ways, their causes, symptoms, and treatments all differ drastically; we will explore all aspects of both conditions to provide you with more information on managing them effectively. We hope to answer all questions related to both conditions in this article “Keratitis VS Conjunctivitis”so as to provide clarity around managing each in turn. We’ll take an in-depth look into both of them so as to provide greater understanding between them both and how best they should be managed over the coming pages!


Keratitis (corneal inflammation) refers to any disorder involving inflammation of the cornea – the clear, dome-shaped surface covering the front of your eye – such as infections, injuries, dryness or medical conditions that affect its health. It may result in redness in or damage to this layer and causes blurry vision for some individuals.

Keratitis VS Conjunctivitis

Causes of Keratitis

There can be various contributing factors that contribute to Keratitis. They include:


Keratitis can be caused by any number of infections ranging from bacteria, viral, or fungal organisms; common examples being herpes simplex virus, varicella-zoster virus and Fusarium or Aspergillus fungus spores. Such outbreaks could stem from poor hygiene practices, contact lens wear or exposure to polluted water sources.

Eye Injuries

Scratches, cuts or foreign objects can lead to keratitis – contact lens wearers being particularly at risk due to improper handling or cleaning procedures that introduce bacteria or irritants into their eyes which lead to inflammation.


Reduced tear production or excessive tear evaporation can make your cornea susceptible to inflammation, leading to Keratitis. Dry eye syndrome, environmental factors or certain medications could increase risk factors leading to dry eye syndrome leading to dry eyes thereby increasing risk for Keratitis.

Underlying Medical Conditions

Certain conditions, such as autoimmune disease and vitamin A deficiency, can have an adverse impact on immunity or corneal health, increasing your chances of keratitis development.

Symptoms of Keratitis

Keratitis symptoms depend upon its cause and degree of inflammation; common signs include:

  • Eye redness
  • Eye pain or discomfort
  • Blurry or decreased vision
  • Sensitivity to light (photophobia)
  • Excessive tearing or discharge
  • Foreign body sensation in the eye

Treatment Options For Keratitis

Treatment options for keratitis vary based on its underlying cause and severity, including:


Antibiotic, antiviral or antifungal eye drops or ointments may be prescribed to combat infections that lead to keratitis, while corticosteroid eye drops may help decrease inflammation. It’s essential that patients adhere to their prescribed treatment schedule and complete all courses of medication as prescribed.

Pain Management

Over-the-counter and prescription pain relievers may be prescribed to relieve eye discomfort associated with keratitis, providing much-needed relief and speeding healing processes. These medicines may reduce discomfort while speeding the healing process as a whole.

Protective Measures

If keratitis was caused by injury, protective eye patch or bandage should be worn over it to shield and speed healing. In such an instance, follow all instructions from healthcare providers as to when and how long a protective eye patch should remain worn for healing to occur.

Addressing Underlying Conditions

If an underlying medical condition is contributing to keratitis episodes, treating that condition could help stop further episodes and keep eyes healthy overall. This could involve treating any autoimmunity issues or nutritional deficiencies or improving overall eye health issues that contribute.


Conjunctivitis, also referred to as pink eye, is an inflammation of the conjunctiva (thin, clear tissue that covers and lines the white part of your eye and lines its inner surface) that forms on its own under your eyelids and covers part of its white part.

Causes of Conjunctivitis

Conjunctivitis may arise for various reasons, including:


Conjunctivitis can be caused by either bacterial or viral infections. Common sources include Staphylococcus aureus or Streptococcus pneumoniae bacteria while viral conjunctivitis may spread via cold virus infections that spread quickly across an organization’s infrastructure.


Pollen, dust mites or pet dander may trigger allergic conjunctivitis which often becomes seasonal with additional symptoms like sneezing and nasal congestion.


Overexposure to smoke, chemicals or chlorine found in swimming pools may lead to an irritant form of conjunctivitis that does not spread contagiously – whether due to environmental influences or occupational hazards.

Symptoms of Conjunctivitis

Conjunctivitis symptoms depend on its cause and type. Common ones include:

 Redness in the white part of the eye and inner eyelid

  • Itching or burning sensation in the eyes
  • Watery or sticky discharge from the eyes
  • Grittiness or foreign body sensation
  • Swollen eyelids
  • Increased sensitivity to light

Treatment Options For Conjunctivitis

Treatment of conjunctivitis will depend on its cause; each case of this disorder requires its own approach.

Bacterial Conjunctivitis

Antibiotic eye drops or ointments may be prescribed to treat bacterial conjunctivitis; to ensure its efficacy and rapid healing. Warm compresses may help alleviate symptoms while speeding healing processes.

Viral Conjunctivitis

As viral conjunctivitis is caused by a virus, antibiotics will not help treat its symptoms; usually this condition resolves within days to weeks without needing additional medical intervention such as cold compresses and artificial tears for relief from symptoms and pain relief. Cold compresses and artificial tears may provide temporary comfort.

Allergic Conjunctivitis

Avoiding allergens and using antihistamine eye drops or oral medications such as Zyrtec(r) can provide temporary relief of allergic conjunctivitis symptoms, while cold compresses may provide further aid. Identifying triggers will also be effective at helping avoid future episodes of allergic conjunctivitis.

Irritant Conjunctivitis

For effective relief from irritant, cleansing with clean water or saline solution and artificial tears is recommended, while limiting exposure to potential triggers will help avoid future episodes of irritation conjunctivitis.

Keratitis and conjunctivitis are two distinct eye conditions involving inflammation that target different parts of the eye. While keratitis mainly impacts cornea, infections, injuries, dryness or medical conditions could all play a part in its cause while conjunctivitis involves conjunctiva inflammation caused by infection, allergies or exposure to irritants; understanding these differences between them will ensure proper diagnosis and treatment options are applied appropriately.


Can Keratitis and Conjunctivitis Occur Together?

Yes, both keratitis and conjunctivitis may coexist concurrently. When this occurs it is essential that medical assistance be sought immediately for accurate diagnosis and treatment.

Can Keratitis or Conjunctivitis lead to permanent vision loss?

Left untreated or with severe complications surfacing, both keratitis and conjunctivitis could potentially result in permanent vision loss unless identified and treated quickly to minimize complications. Early diagnosis is key in order to avoid lasting vision impairment from occurring; prompt medical diagnosis is also vitally important.

Are keratitis and conjunctivitis contagious?

Though both conditions can be contagious, viral conjunctivitis is particularly contagious and must be carefully managed in order to stay contained and contained from spreading infection from person to person. Therefore, proper hygiene must be implemented at all times when touching or rubbing eyes in order to stop further infection spread.

Do contact lens wearers develop keratitis or conjunctivitis more readily?

Contact lens wearers have an increased risk of keratitis when compared with non-wearers due to bacteria being trapped between the lens and cornea, increasing likelihood of infection and increasing chance of disease transmission. Proper hygiene and lens care practices must be adhered to in order to decrease this risk and keep yourself protected against it.

When should I seek medical help for my keratitis or conjunctivitis?

Symptoms that suggest eye redness, pain or blurriness require seeing an eye care specialist as soon as possible to ensure accurate diagnosis and effective treatments based on what may be underlying factors in your case. They will provide accurate diagnoses & tailor treatments according to what may cause or aggravate symptoms such as redness.
