hypotropia การใช้

There are also vertical tropias ( hypertropia and hypotropia ) and cyclotropias.
If the image of the right eye is higher than that of the left, this means the right eye is lower than the left . This could be either a right hypotropia or a left hypertropia.
In Graves ophthalmopathy, it is not uncommon to see an esotropia ( due to pathology of the medial rectus muscle ) co-morbid with a hypotropia ( due to pathology of the inferior rectus muscle ).
A cyclodeviation may thus be corrected at the same time with a correction of a vertical deviation ( hyper-or hypotropia ); cyclodeviations without any vertical deviation can be difficult to manage surgically, as the correction of the cyclodeviation may introduce a vertical deviation.
Depending on the symptoms, the surgical correction of cyclotropia may involve a correction of an associated vertical deviation ( hyper-or hypotropia ), or a Harada Ito procedure or another procedure to rotate the eye inwards, or yet another procedure to rotate it outwards.
