Entropion

Your eye care specialist will start by asking you about your symptoms and medical history. They’ll perform an eye exam, looking for any signs of skin irritation, infection or scarring. They’ll pay close attention to the edges of your eyelid, as there are other medical conditions that can mimic entropion. They want to ensure they make the correct diagnosis to decide the proper treatment.

Tests that are used to diagnose entropion

Your provider may perform several tests to help diagnose entropion. These tests include:

• Snap-back test. Without allowing you to blink, your provider pulls your eyelid down and observes how long it takes to return to its original position.
• Distraction test. Your provider pulls your eyelid away from your eye and measures the distance. They consider more than 6 millimeters abnormal.
• Slit lamp exam. A slit lamp is a special microscope with a bright light that your provider uses to examine your eye, looking for signs of the condition.
