Exophoria. Exophoria is a form of heterophoria in which there is a tendency of the eyes to deviate outward. [1] During examination, when the eyes are dissociated, the visual axes will appear to diverge away from one another. [2] The axis deviation in exophoria is usually mild compared with that of exotropia.
A fixation disparity is not constant within a certain observer, but can vary depending on the viewing conditions. If test prisms with increasing amount are placed in front of the observer’s eyes, the fixation disparity changes in the eso direction with base-in prisms and in the exo direction with base-out prisms (Fig. 3).

Plant taxonomy. Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two.
Specialty. Ophthalmology. Exotropia is a form of strabismus where the eyes are deviated outward. It is the opposite of esotropia and usually involves more severe axis deviation than exophoria. People with exotropia often experience crossed diplopia. Intermittent exotropia is a fairly common condition. "Sensory exotropia" occurs in the presence ...
Rosaceae (/ roʊˈzeɪsiː.iː, - si.aɪ, - si.eɪ /), [4][5] the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera. [6][7][8] The name is derived from the type genus Rosa. The family includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. [9]
Ilex vomitoria. Ilex vomitoria, commonly known as yaupon (/ ˈjɔːpɒn /) or yaupon holly, is a species of holly that is native to southeastern North America. [2] The word yaupon was derived from the Catawban yą́pą, from yą- tree + pą leaf. [3] Another common name, cassina, was borrowed from Timucua [4] (despite this, it usually refers to ...
