Esophoria is an eye condition involving inward deviation of the eye, usually due to extra-ocular muscle imbalance. It is a type of heterophoria .
Heterophoria is an eye condition in which the directions that the eyes are pointing at rest position, when not performing binocular fusion, are not the same as each other, or, "not straight". This condition can be esophoria, where the eyes tend to cross inward in the absence of fusion; exophoria, in which they diverge; or hyperphoria, in which ...
Ophthalmology. Esotropia is a form of strabismus in which one or both eyes turn inward. The condition can be constantly present, or occur intermittently, and can give the affected individual a "cross-eyed" appearance. [1] It is the opposite of exotropia and usually involves more severe axis deviation than esophoria.
Anisometropia is a condition in which a person's eyes have substantially differing refractive power. [1] Generally, a difference in power of one diopter (1D) is the threshold for diagnosis of the condition . [2] [3] Patients may have up to 3D of anisometropia before the condition becomes clinically significant due to headache, eye strain, double vision or photophobia. [4]
Thalassophobia. Thalassophobia (from Ancient Greek θάλασσα (thálassa) 'sea', and φόβος (phóbos) 'fear') [1] is the persistent and intense fear of deep bodies of water, such as the ocean, seas, or lakes. Though very closely related, thalassophobia should not be confused with aquaphobia, which is classified as the fear of water itself.
The Eye of Providence or All-Seeing Eye is a symbol depicting an eye, often enclosed in a triangle and surrounded by a ray of light or a halo, intended to represent Providence, as the eye watches over the workers of mankind. [1] [2] [3] A well-known example of the Eye of Providence appears on the reverse of the Great Seal of the United States ...
Christianity. "The eye of a needle" is a portion of a quotation attributed to Jesus in the synoptic gospels : "I tell you the truth, it is hard for a rich man to enter the kingdom of heaven. Again I tell you, it is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God."
Richat Structure. / 21.114700°N 11.394300°W / 21.114700; -11.394300. The Richat Structure, or Guelb er Richât ( Arabic: قلب الريشات Qalb ar-Rīšāt ), is a prominent circular geological feature in the Adrar Plateau of the Sahara. It is located near Ouadane in the Adrar Region of Mauritania.
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 .
Ophthalmology. Epiphora is an overflow of tears onto the face, other than caused by normal crying. It is a clinical sign or condition that constitutes insufficient tear film drainage from the eyes, in that tears will drain down the face rather than through the nasolacrimal system. [1]
