- RA (the most common disease cause) and Paget disease of the cervical spine can cause atlantoaxial dislocation or subluxation, basilar invagination, or platybasia. Metastatic tumors that affect bone can cause atlantoaxial dislocation or subluxation.

Esotropia For specific information, see infantile esotropia and accommodative esotropia. Esotropia can also be secondary to other conditions. Poor vision can cause in-turning of an eye. Various neurological conditions (hydrocephalus, stroke, etc.) can cause an eye to turn inward. A number of medical conditions can cause esotropia (thyroid eye disease, Duane syndrome, etc.).

Cover Tests In the case of a phoria, or latent deviation, the examiner observes the eye underneath the occluder. In the case of a phoria, the uncovered eye does not move however the eye that is under the cover will deviate when occluded and return to a straight position when the occluder is removed. The cover-uncover test can differentiate whether the misalignment is a phoria or a tropia.

- 22) It may be indicated by the presence of a subluxated lens, phacodonesis (increased mobility of the lens) or iridodonesis (increased mobility or tremulousness of the iris).

Definition Shoulder subluxation can lead to soft tissue damage as traction damage can occur due to gravitational pull forces and poor protection is offered by a weak shoulder. Shoulder subluxation is usually quite painful, and there might be a partial numbness of the shoulder, arm and hand.[21]

3D Skeletal System: Atlas, Axis, and the Atlanto-Axial Relationship The ligaments in the spine support and reinforce the joints between the vertebrae. The atlas and axis in particular work with the ligaments to move the neck. The atlas and the occipital bone form the atlanto-occipital joint, which allows neck flexion.When you nod your head as if to say yes, that is neck flexion.The atlas and axis form the atlanto-axial joint, which allows head rotation.he atlas and axis in particular work with the ligaments to move the neck.

exotropia Divergence of the lines of vision of the two eyes. Divergent squint. In exotropia one eye points at the object of regard, the other is directed outwards. In exotropia acquired in adult life there is usually double vision (diplopia). In childhood, the false image may be suppressed and long-term visual acuity may be affected in one eye. See also ESOTROPIA.

- Eyeglasses do not correct visual loss that occurs when a pituitary tumor has affected the optic nerves or optic chiasm. Eyeglasses are used to focus light in front of the eye. When the optic nerve or chiasm is injured, the problem causing loss of vision is behind the eye.

- Atlanto-axial instability or AAI describes an increased flexibility between the first and second bones of the neck. Most individuals with Down syndrome have some increased flexibility of joints, called ligamentous laxity, which can affect any of their joints.

Differential diagnosis of unilateral retro-orbital pain, photophobia They say that ophthalmologists should consider cervicogenic eye pain in the differential diagnosis of unilateral eye pain. The woman had developed the symptoms a day or two after left optic nerve sheath fenestration (ONSH) for vision loss secondary to neuroretinitis. She experienced the pain for most of every day for 3.5 years after the surgery.

Entropion correction Procedure For other patients, a lateral tarsal strip procedure, often combined with a lower eyelid retractor advancement, is performed in the operating theatre. This is a very convenient operation for the patient as no sutures need to be removed.

Everything You Should Know About Monovision Surgical monovision: The effects of monovision can also be achieved with LASIK (Laser In Situ Keratomileusis) surgery. Instead of using contact lenses, LASIK surgery is used to adjust one eye for focusing on far-away objects, and one eye for focusing on close-up objects.he reverse is true for focusing on objects that are closer. For monovision patients, the dominant eye will be fitted with the contact lens that is suited for driving or other activities that require focusing on objects far away. Closer objects may appear to be blurrier through this eye.

Aphakia in Adults and Children Aphakia also causes loss of accommodation, meaning that the eye cannot maintain its focus on an object as that object moves closer or farther away. Other vision changes you may notice include erythropsia, in which objects appear reddish, and cyanopsia, in which everything appears to have a blue tint.

Agnosia It is usually associated with brain injury or neurological illness, particularly after damage to the occipitotemporal border, which is part of the ventral stream. Agnosia only affects a single modality, such as vision or hearing.

Atlanto-axial joint The atlantoaxial joint is a joint in the upper part of the neck between the first and second cervical vertebrae; the atlas and axis. It is a pivot joint. The atlantoaxial joint is of a complicated nature. It consists of no fewer than four distinct joints. There is a pivot articulation between the odontoid process of the axis and the ring formed by the anterior arch and the transverse ligament of the atlas.

Description Atlanto-axial joint. Search. The atlanto-axial joint is a joint between the first and second cervical vertebrae; the Atlas and Axis. It is a complex joint made up of three synovial joints and constitutes the most mobile articulation of the spine.otions Available. Rotation is the primary movement at this joint - 50% of cervical rotation (50°) comes from the atlanto-axial articulation. This is allowed by the pivot articulation between the odontoid process of the axis and the ring formed by the anterior arch and the transverse ligament of the atlas.

Visual Midline Shift Syndrome Some patients may have an anterior visual midline shift, causing a forward lean (flexion), or a posterior midline shift, causing a backward lean (extension). When a patient develops a visual midline shift, physical therapy or occupational therapy treatments for balance, transfer, or ambulation may plateau.

Vision and Rehabilitation After Brain Trauma (Part 2) Nystagmus is a repetitive movement of the eyeball during which the eye seems to drift off target and then quickly corrects to re-gaze at the target. This condition can occur after brain injury and causes considerable reduction of visual clarity as well as a sense of dizziness.

Craniocervical Junction Disorders These disorders can put pressure on the lower parts of the brain, the top part of the spinal cord, or nearby nerves. The resulting symptoms can be serious. For example, misalignment of the first and second spinal bones (atlantoaxial subluxation or dislocation) can put pressure on the spinal cord.
