Eye Pain: Common Causes and Tests for Diagnosis

Eye pain can be an uncomfortable and sometimes alarming symptom. It can range from a mild irritation to severe discomfort. Understanding the potential causes of eye pain and the diagnostic tests available can help you make informed decisions about your eye health.

What Causes Eye Pain?

Eye pain can be caused by a variety of factors, ranging from minor issues to more serious conditions. Common causes include:

• Dry Eyes: This occurs when your eyes do not produce enough tears or the right quality of tears to keep the eye surface lubricated.
• Conjunctivitis: Also known as pink eye, this is an inflammation or infection of the outer membrane of the eyeball and the inner eyelid.
• Glaucoma: A group of eye conditions that damage the optic nerve, often associated with increased pressure in the eye.
• Corneal Abrasion: A scratch on the surface of the cornea, which can be caused by foreign objects or trauma.
• Uveitis: Inflammation of the uvea, the middle layer of the eye.

Diagnostic Tests for Eye Pain

When experiencing eye pain, healthcare providers may use several tests to determine the underlying cause:

• Visual Acuity Test: Measures how well you see at various distances. It helps identify vision problems that might be causing eye pain.
• Slit Lamp Examination: A microscope with a bright light allows the doctor to examine the structures at the front of the eye, such as the cornea, lens, and iris.
• Tonometry: Measures the pressure inside your eyes. It is crucial for diagnosing glaucoma.
• Ophthalmoscopy: Allows the doctor to look at the back of the eye, including the retina and optic nerve.
• Fluorescein Stain: A dye is applied to the eye to highlight any damage to the cornea, such as abrasions or ulcers.

When to See a Doctor

While some eye pain can be managed at home, certain situations warrant a visit to a healthcare provider:

• Severe or persistent pain
• Sudden vision changes
• Eye pain accompanied by headache, nausea, or vomiting
• Visible injury or foreign object in the eye
• Pain that does not improve with over-the-counter medications

Frequently Asked Questions
