Ectropion can usually be diagnosed with a routine eye exam and physical. Your doctor may pull on your eyelids during the exam or ask you to close your eyes forcefully. This helps him or her assess your eyelid's muscle tone and tightness.
If your ectropion is caused by a scar, tumor, previous surgery or radiation, your doctor will examine the surrounding tissue as well.
Understanding how other conditions cause ectropion is important in choosing the correct treatment or surgical technique.
