What’s the difference between a tropia and a phoria?
These are terms to describe when the eyes are not in alignment with each other. A tropia is always present, while phorias are there “some of the time,” such as when the patient is tired or when fusion is broken (you cover an eye and it starts to drift).
For example: You can have an exotropia or esotropia. You can also have an exophoria and esophoria.
nice thanks

Hi!
I was just wondering if a child has for example a left accommodative esotropia at distance (shown on cover/uncover test), would it also be present at near? Or because at near the patient is already accommodating at a near point, would it be hidden during cover test? Or at near would it be broken down with the alternating cover test and show up as a esophoria?
Thank you very much, not quite sure what happens at near ! Can you ever have a tropia in distance and phoria at near?
so basically tropia ia always a manifest presence while phoria is hidden or in phoria phatients their eyes have the tendency to turn when in such comdition as feelung tired？
nice.
Tropias are not always present, they can be intermittent. Also, phorias are always present if you are looking for them/measuring them correctly. Your answer is a little too simplified.And patients can have a tropia that is only present at one distance or in one field of gaze.
is it possible for both tropia and phoria present at the same time? if yes what is the methode to differntiate between them? thanks alot .
