Ophthalmology: tropias versus phorias

This video shows animated cartoons demonstrating the difference between a tropia and a phoria. We go over the cover-uncover test and the cross-cover test. This segment was extracted from the Pediatric Ophthalmology lecture from OphthoBook.com

You do realize, that in no way, do these remedies address the actual problem. ?? If there is an underlying neurological problem, that could be treated, wouldn't the prisms, or especially surgery, cover up the actual issue. Obviously the body is adapting for a reason . . . right. The intelligence of the body has a reason. Or do we take another Tylenol . . . another pepsid . . . . another benadryl.

@DrJam0073 The cause of ocular misalignment must be determined 1st, but diplopia is rarely caused by "treatable" neuro problems. Most double vision is from aging decompensation, or untreatable strokes that you have to wait to see if the cranial nerve will repair itself

Prism and surgery are not a "fix" but a way to keep our patient from suffering from double vision. In children, you need to fix eye alignment quickly (even surgery) or they will develop permanent vision loss from amblyopia .

Thank you for uploading this video, very helpful.

When determining the size of a phoria which direction should the prism base be held in front of the eye?

Wow.....thanks for this....I just had corrective surgery for esotrophia...lazy eye went inward. It was my 4th surgery. I had 2 as a kid, and now I am 39. Praying this will totally straighten my eye. The weird thing is that my eyes are not level horizontally either. One eyebrow/eye is higher than the other. Why would this be? Could it have been from the corrective surgery that went bad on me when I was kid. They had to stop surgery because was hemoraging to much.

Hi, I am 32 years old and try to do this test a week ago, but the doctor was so rush on the tests she did.

My dominant eye is the right one, and she placed the prism over my left eye.

On your video you showed that it should be placed on the dominant eye.

She ask me to look to a letter H and with the prism, I started to see a hallow (no double) H on the right of it.

Should I look for another doctor or did I understand your video incorrectly.

Thank you

Leo
