What is Commonly Misdiagnosed as Pink Eye?

Inflammation of the conjunctiva is one of the symptoms of conjunctivitis, an eye condition that affects many people that is defined by inflammation of the conjunctiva, which is the thin membrane covering the white area of the eye and lines the inside of the eyelids. It typically manifests with symptoms including redness, itching, tearing, and discharge and is brought on by viral or bacterial infections, allergies, or irritants. While pink eye is an easy diagnosis, other eye disorders might resemble its symptoms, resulting in a false positive. We will examine a few of the illnesses that are frequently misdiagnosed as pink eye in this post, highlighting their similarities and distinctions. What is Commonly Misdiagnosed as Pink Eye

Conjunctivitis Allergic

Allergic conjunctivitis is a frequent illness that is susceptible to misdiagnosis since it has many symptoms with infectious pink eye. It is caused by allergens such as pollen, pet dander, dust mites, or mold spores coming into contact with the eye’s surface. The conjunctiva becomes inflamed, leading to redness, itching, watering, and sometimes a stringy or watery discharge. The main distinguishing factor between allergic conjunctivitis and infectious pink eye is the absence of contagiousness in allergic conjunctivitis. Allergic conjunctivitis is not transmitted from person to person like viral or bacterial pink eye.

Dry Eye Syndrome

Dry eye syndrome occurs when the eyes do not produce enough tears or the tears evaporate too quickly. While it may not cause redness as prominent as pink eye, it can lead to irritation, a gritty sensation, and occasional redness. Dry eye syndrome may also cause excessive tearing as a reflex response to the irritation. The similarity in the symptom of redness can lead to confusion between dry eye syndrome and pink eye. A key difference is the absence of discharge in dry eye syndrome, which is commonly seen in infectious pink eye.

Bacterial Keratitis

Bacterial keratitis is a dangerous disorder when the cornea, the transparent front surface of the eye, becomes infected. It has symptoms in common with pink eye, particularly bacterial conjunctivitis, such as redness, discomfort, and discharge. The location of the infection and the severity of the symptoms are whatever makes the difference. Extremely painful eyes, light sensitivity, and a foggy or hazy look of the cornea are all common symptoms of bacterial keratitis. Bacterial keratitis must be diagnosed as soon as possible since, if untreated, it can cause visual loss. Read about Borgess Patient Portal

Viral Keratitis

Another disorder whose symptoms are similar to those of viral conjunctivitis is viral keratitis. This is especially true if the patient has recently experienced cold sores or has been infected with the herpes simplex virus. Both illnesses can result in tears, redness, and discomfort. Viral keratitis, on the other hand, targets the cornea specifically and results in a painful irritated eye with a potential vision impairment. Through a thorough eye exam and proper diagnostic testing, an ophthalmologist can distinguish between viral keratitis and viral conjunctivitis.

Subconjunctival Hemorrhage

A subconjunctival hemorrhage occurs when a blood vessel in the conjunctiva bursts, leading to the appearance of a bright red patch on the white part of the eye. This condition can be alarming and may be mistaken for infectious pink eye due to its noticeable redness. However, subconjunctival hemorrhage is typically painless and does not cause itching, tearing, or discharge, which are characteristic symptoms of pink eye.

Contact Lens-Related Issues

Contact lens wearers may experience conditions that mimic pink eye, such as contact lens-induced keratitis or contact lens-related acute red eye (CLARE). These conditions can cause redness, discomfort, and sensitivity to light. A thorough evaluation by an eye care professional is essential to differentiate contact lens-related issues from pink eye, as they may require different management approaches.


Even though pink eye (conjunctivitis) is a common and simple diagnosis, it’s important to be aware of other eye illnesses that might seem quite similar to pink eye. Among the disorders that could be mistaken for pink eye include allergic conjunctivitis, dry eye syndrome, bacterial and viral keratitis, subconjunctival hemorrhage, and problems with contact lenses.

The right diagnosis is essential for choosing the right course of action and avoiding problems. For the best possible eye health and effective management of your disease, you should seek immediate assessment and diagnosis from an eye care specialist, such as an optometrist or ophthalmologist, if you suffer eye redness, irritation, or discomfort. Keep in mind that only a trained eye care professional can correctly identify and treat your unique eye disease, ensuring the best possible result for your ocular health.
