How to Pronounce Proptosis

Proptosis is pronounced prop-TOH-sis. Say it like "PROP" (rhymes with "drop"), then "TOSIS" (sounds like "toe-sis"). The stress falls on the second syllable, so TOH gets the emphasis: prop-**TOH**-sis.

Many people stress the first syllable by accident, saying **PROP**-tosis instead of prop-**TOH**-sis. Remember: the emphasis belongs on TOH, the middle part of the word.

Yes! Proptosis breaks into three syllables: prop-to-sis. When you say it slowly, you'll hear three separate parts. The second syllable (to) gets the stress, making it sound like prop-**TOH**-sis when spoken at normal speed.

Proptosis comes from Greek. The prefix 'pro-' means "forward," and 'ptosis' (pronounced TOH-sis) means "a falling or dropping." Put together, proptosis literally means "a falling forward," which describes the main feature of this condition.

The related term 'exophthalmos' (pronounced ex-op-THAL-mus) means the same thing and is often used interchangeably in medical settings. Both words describe the same condition, though proptosis is the more common term in everyday medical conversation.

Proptosis is a medical way of saying that one or both eyes are bulging or sticking out more than normal. If someone has proptosis, their eye or eyes appear to be pushed forward out of the eye socket.

The word 'ptosis' (TOH-sis) is related—it means a drooping or sagging, often used to describe a drooping eyelid. Another related term is 'exophthalmos,' which means the same thing as proptosis. All three words share Greek roots related to movement or position of body parts.

A doctor might say: "The patient presented with proptosis of the left eye." This means the patient's left eye was bulging forward more than it should be. It's a neutral, descriptive term used to report a visible finding.
