Binocular Vision

In recent times, binocular vision has become increasingly relevant in various contexts. Microsoft Word - BINOCULAR VISION.doc - University of Iowa. Binocular Single Vision may be defined as the state of simultaneous vision, which is achieved by the coordinated use of both eyes, so that separate and slightly dissimilar images arising in each eye are appreciated as a single image by the process of fusion. Thus binocular vision implies fusion, the blending of sight from the two eyes to form a single percept.

General Refraction Techniques - University of Iowa. The goal of the subjective refraction is to achieve clear and comfortable binocular vision. The ability of the refractionist to maintain control during the refraction is directly related to their ability to communicate clearly and directly with the patient.

The subjective refraction starts after retinoscopy, or after auto refraction. Functional Visual Loss - University of Iowa. A patient response of “none” when the fingers are silently displayed in the “non-seeing” field confirms vision in that area. Moreover, monocular and binocular visual field testing: If the patient reports a monocular visual field defect, the visual field test can be repeated with both eyes open. Building on this, monofixation Syndrome - University of Iowa.

The effect of glasses to treat the decreased vision on the left was subjectively insignificant because she had foveal suppression in this eye under binocular conditions related to monofixation syndrome. Convergence Insufficiency - University of Iowa. A randomized clinical trial of vision therapy/orthoptics versus pencil pushups for the treatment of convergence insufficiency in young adults.

Clinical Management of Binocular Vision: Heterophoric, Accommodative, and Eye Movement Disorders. Philadelphia: Lippincott, Williams and Wilkins. EyeRounds.org - Ophthalmology - The University of Iowa. Monofixation syndrome is characterized by peripheral fusion and central suppression. Even though a macular scotoma develops in the non-fixating eye (central suppression), binocular fusion of points in the peripheral retina is retained (peripheral fusion).

EyeRounds.org: Case56 Duane Retraction Syndrome Globe Retraction. Globe retraction and field of single binocular vision can be improved in patients with Duane retraction syndrome through surgical intervention. One could consider inactivation of lateral rectus by disinserting the muscle with reattachment to the orbital periosteum, accompanied by augmented vertical muscle transposition.

INTERMITTENT EXOTROPIA: A Major Review - University of Iowa. Introduction Exodeviations or divergent squint occurs as a result of certain obstacles to development or maintenance of binocular vision and/ or due to defective action of the medial rectus muscles. Additionally, small exophorias are found in high frequency in the normal population and 60-70% of normal newborn infants have a transient exodeviation that resolves by 4-6 months of age (1-3). From another angle, plus Cylinder Subjective Refraction Instructional Video. Similarly, the goal is the least amount of cylinder power that provides for clearest distance vision. Department of Ophthalmology Update.

Orthoptics is an allied health profession pertaining to the study of eye movements and binocular vision. UIHC has one of the few orthoptic training programs in the country and has several orthoptists within our Pediatric Ophthalmology and Strabismus Clinic.
