what is commonly misdiagnosed as pink eye


Pink eye, also known as conjunctivitis in the medical world, is a common eye ailment characterised by redness, irritation, and discharge. Several other eye disorders, however, can mirror its symptoms, leading to misdiagnosis. Understanding these disorders is necessary for effective treatment and care.

Understanding The Pink Eye

Pink eye is caused by an inflammation or infection of the conjunctiva, the clear membrane that borders the eyelid and covers the white area of the eyeball. Viruses, bacteria, allergies, or irritants can all cause it. If caused by viruses or bacteria, the disease is highly communicable.

Pink Eye is frequently confused with the following conditions:

  • Symptoms of Dry Eye Syndrome: Redness, a gritty feeling in the eyes, and occasionally watery tears.
    Cause: Insufficient tear production or tears of poor quality.
    Unlike pink eye, it is not contagious and is frequently related with environmental variables or screen time.
  • Blepharitis symptoms include red, swollen eyes, crusty eyelashes, and, in some cases, a burning sensation.
    Inflammation at the base of the eyelashes is the cause.
    It primarily affects the eyelids and is frequently a chronic illness.
  • Keratitis symptoms include redness, discomfort, and hazy vision, which may be accompanied by a discharge.
    Cause: Corneal infection or damage.
    The difference is that this condition is more dangerous and, if not addressed, can result in vision impairment.
    Symptoms of Allergic Reactions: Redness, itching, and swelling, typically accompanied by sneezing or a runny nose.
    Allergic reaction to allergens such as pollen, dust, or pet dander.
    Differentiation: Allergic reactions frequently affect both eyes at the same time and are accompanied by other allergy symptoms.
  • Symptoms of Subconjunctival Haemorrhage: A bright red patch on the white of the eye.
    The cause is a tiny blood vessel break behind the conjunctiva.
    The difference is that there is no discharge or substantial discomfort, and it is not contagious.
    Corneal Ulcer Symptoms: Redness, acute discomfort, poor vision, and light sensitivity.
    Infection of the cornea, which occurs frequently in contact lens wearers.
    A more serious condition that necessitates prompt medical attention.

  • The Importance of Correct Diagnosis
    When these illnesses are misdiagnosed as pink eye, they might result in inefficient or hazardous therapies. Antibiotics, for example, are ineffective for viral conjunctivitis and can contribute to antibiotic resistance. Similarly, treating a more serious ailment, such as keratitis, with basic pink eye remedies might aggravate symptoms and lead to complications.


Pink eye symptoms are distinct, yet they overlap with a number of other eye disorders. A healthcare expert should be consulted for an accurate diagnosis and suitable therapy. Understanding the distinctions between these illnesses can aid in identifying the correct problem and getting timely medical attention.
