Eye Infections

An eye infection is probable if you have any of the following symptoms: discomfort, swelling, itching, or redness around your affected eye. Viral, bacterial, and fungal eye disorders may be treated differently depending on their etiology.

Because eye infections aren’t tricky to detect, it’s best to have them treated as soon as possible.

These eight most common eye infections are covered here to determine what’s causing them and what to do about them.

Conjunctivitis/pink eye

Conjunctivitis is one of the most frequent infections of the eye. The thin outermost membrane was covering your eyeball, the conjunctiva, becomes contaminated with bacteria or a virus, which causes blood vessels in the conjunctiva to leak.

Your eyes will get pink or red and irritated as a consequence.

Allergic reactions or exposure to chemicals like chlorine in pools may also cause it.

Bacterial or viral conjunctivitis is very infectious. You may continue distributing the infection to others for up to two weeks after the infection. If you notice any of the following symptoms, make an appointment with your doctor.

  • Tinted eyes with a ruby or pink hue
  • wake up ocular discharge that is the heaviest.
  • persistent itching or the sensation that something is always in your eyes
  • Tears, particularly in one eye, are more frequent than average.

Depending on the kind of conjunctivitis you have, you may need one or more of the following therapies:

  • For eye infections caused by bacteria, you may use antibiotic drops, ointments, or oral drugs. In most cases, symptoms subside within a few days after taking antibiotics.
  • Viral: There is no known cure for this illness. After 7 to 10 days, symptoms begin to subside. Clean, warm, moist cloths may alleviate eye irritation, so wash your hands regularly and minimize eye contact with others.
  • Over-the-counter (OTC) antihistamines like Benadryl or Claritin may help alleviate the symptoms of an allergic reaction. Antihistamine eye drops and anti-inflammatory eye drops may be used to ease the symptoms of allergies and hay fever.

They have infected cornea resulting in infectious keratitis. The cornea protects your pupil and iris from the outside world a transparent covering. A bacterial, viral, fungal, or parasitic infection or an eye injury may cause keratitis. A condition isn’t necessarily to blame for keratitis, just cornea swelling. Keratitis symptoms include:

  • Inflammation and redness in your eye
  • irritation or pain in the eyes
  • extra tears or an irregular outpouring of tears
  • opening and closing of the eyelids are painful or uncomfortable.
  • Vision loss or fuzzy vision are examples of this.
  • having something caught in your eye and cause increased sensitivity to light

As soon as you discover any keratitis symptoms, make an appointment with your doctor to get the infection under control. Treatments for keratitis include:

  • Bacterial. A keratitis infection may typically be treated with antibacterial eye medicines within a few days. In the case of more severe illnesses, oral antibiotics are usually prescribed.
  • Fungal. Because of the fungal infection, you’ll require antifungal eye drops or medicine to get rid of it. This might take anything from a few weeks to many months.
  • Viral. A virus cannot be eradicated. A few days to a week of oral antiviral medicine or eye drops might be used to treat the infection. Even after successful therapy, the symptoms of viral keratitis may recur.


Bacterial or fungal infections may cause endophthalmitis, an inflammation of the eye’s inside. Endophthalmitis is the most prevalent cause of Candida fungal infections.

Cataract surgery, for example, may lead to this illness, although it is uncommon. It’s also possible that it happens if something gets stuck in your eye. Following surgery or an eye injury, you should be on the lookout for the following signs and symptoms:

  • eye discomfort that ranges from moderate to severe
  • loss of vision in one or both eyes
  • visual acuity is impaired
  • eye and eyelid redness or swelling
  • discharge of pus from the eye
  • strong light sensitivity

The infection’s etiology and severity determine treatment. Before anything else, you’ll need a needle to inject medicines straight into your eye to treat the disease. A corticosteroid injection may also be used to reduce inflammation.

The infection can only be treated as soon as the object that caused it is removed. Never attempt to remove an item from your eye on your own; call 911 or go to the nearest emergency room.

As soon as you finish taking antibiotics and removing any foreign objects, your symptoms will begin to improve.

Inflammation of the skin folds that cover your eyes is known as blepharitis. The oil glands at the base of your eyelashes can become clogged, resulting in this type of inflammation. Bacteria may be the cause of blepharitis.

Blepharitis can generate a variety of symptoms, some of which are documented below:

  • redness, itchiness, and swelling of the eye or eyelid
  • an overly oily eyelid
  • burning sensation in the eyes
  • Fumbling as if something is lodged in your eyeballs
  • a heightened ability to see in the dark
  • making a more significant number of tears than normal
  • the appearance of crust in the lashes or around the edges of your eyes

Blepharitis may be treated in a variety of ways, including:

  • Swelling in the eyelids may be alleviated by rinsing them with warm water and patting them dry with a clean cloth.
  • Using eye drops or ointments containing corticosteroid steroids to reduce inflammation
  • To keep your eyes moist and avoid dryness, use lubricating eye drops.
  • Taking antibiotics in the form of eye drops, ointments, or oral medicine


An oil gland on the outside corners of your eyelids may produce a pimple-like protrusion called a sty (sometimes spelled hordeolum). A buildup of dead skin, oils, and other debris may lead to an overgrowth of germs in your gland. Eventually, an abscess develops due to the infection.

Symptoms of a sty include:

  • sensitivity or discomfort
  • Irritation or itching
  • swelling
  • making a more significant number of tears than normal
  • the appearance of crust on your eyelids
  • production of tears

Sties may be treated in a variety of ways, including:

  • For 20 minutes a few times a day, apply a clean, warm, wet towel to your eyelids
  • Cleansing your eyelashes with gentle, fragrance-free soap and water
  • We are Discontinuing contact lenses or eye makeup until the infection has subsided while using over-the-counter (OTC) pain medications such as acetaminophen (Tylenol).
  • The use of antibiotic ointments to combat the proliferation of pathogens

If the pain or swelling persists after your therapy, make an appointment with your doctor. In 7 to 10 days, a sty should be gone. Ask your doctor if there are any other options if it doesn’t work.
