Conjunctivitis, commonly known as pink eye, is an inflammation of the conjunctiva—the thin, transparent membrane covering the white part of the eye. It may be caused by a viral or bacterial infection, allergies or irritation. Many cases can be safely assessed during an online consultation.

Symptoms

Common symptoms of conjunctivitis include:

• Redness in one or both eyes

• Watery or sticky eye discharge

• Itchy or irritated eyes

• Gritty or burning sensation

• Crusting of the eyelids, particularly on waking

• Excessive tearing

• Mild blurred vision that clears after blinking

• Swollen eyelids

Symptoms may affect one eye initially before spreading to the other.

Causes

Conjunctivitis can have several different causes, including:

• Viral infections

• Bacterial infections

• Allergies (such as hay fever)

• Contact lens irritation

• Smoke, dust or chemical irritants

Viral and bacterial conjunctivitis are contagious and can spread easily through close contact.

Diagnosis

A diagnosis can usually be made based on your symptoms and medical history.

During your consultation, your doctor will assess whether your conjunctivitis is more likely to be viral, bacterial or allergic, as this determines the most appropriate treatment. If your symptoms suggest a more serious eye condition, you may be advised to attend an in-person assessment.

Treatment

Treatment depends on the underlying cause.

Your doctor may recommend:

• Lubricating eye drops

• Cold compresses to relieve discomfort

• Good hand hygiene to reduce the spread of infection

• Avoiding contact lenses until symptoms have resolved

If a bacterial infection is suspected, antibiotic eye drops or ointment may be prescribed following an assessment.

When should I seek urgent medical care?

You should seek urgent medical attention if you have:

• Severe eye pain

• Sudden loss of vision

• Sensitivity to light (photophobia)

• A significant eye injury

• Symptoms while wearing contact lenses accompanied by severe pain or reduced vision

• Increasing redness or swelling despite treatment

These symptoms may indicate a more serious eye condition requiring urgent assessment.
