Esophoria is an eye condition involving inward deviation of the eye, usually due to extra-ocular muscle imbalance. It is a type of heterophoria. Cause. Causes include: Refractive errors; Divergence insufficiency; Convergence excess; this can be due to nerve, muscle, congenital or mechanical anomalies.
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.
If the eye was exotropic, covering the fixating eye will cause an inwards movement; and if esotropic, covering the fixating eye will cause an outwards movement. The alternating cover test, or cross cover test is used to detect total deviation (tropia + phoria).
Amblyopia. 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 ...
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 ...
Aniseikonia. Aniseikonia is an ocular condition where there is a significant difference in the perceived size of images. It can occur as an overall difference between the two eyes, or as a difference in a particular meridian. [1] If the ocular image size in both eyes are equal, the condition is known as iseikonia. [2]
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 .
The Eye of Providence can be found on the reverse of the Great Seal of the United States, as seen on the U.S. $1 bill, depicted here. 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 ...
Thalassophobia (from Ancient Greek θάλασσα (thálassa) 'sea', and φόβος (phóbos) 'fear') 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 Seafarer is an Old English poem giving a first-person account of a man alone on the sea. The poem consists of 124 lines, followed by the single word "Amen". It is recorded only at folios 81 verso – 83 recto [1] of the tenth-century [2] Exeter Book, one of the four surviving manuscripts of Old English poetry.
