vision therapy for oculomotor dysfunctions in a relatively large sample of ambulatory, visually symptomatic, predom-inantly adult outpatients having either a mild TBI or a CVA. Methods A computer-based query was obtained for ABI patients examined between October 1, , and October 7, , using either the (new patient evaluation) or Persons with amblyopia, especially those with strabismus, are known to exhibit abnormal fixational eye movements. In this paper, we compared six characteristics of fixational eye movements among normal control eyes (n=16), the non-amblyopic fellow eyes and the amblyopic eyes of anisometropic (n=14) and strabismic amblyopes (n=14).These characteristics include the frequency, magnitude of Cited by:
Vision Problems | 2 MS-Related Vision Problems Optic neuritis, an inflammation of the optic nerve, is the most common visual disorder associated with MS. Symptoms of optic neuritis include blurred vision, dimming of colors, pain when the eye is moved, blind spots and lessening of ability to see contrast (contrast sensitivity).

This book is the outcome of years of research on the correlation between fixation disparity and oculomotor imbalance by Dr. Kenneth Ogle and his colleagues at the Mayo Clinic.
They state that "although the promise of the study was not fully realized, sufficient valuable data was obtained to justify the writing of this monograph."Cited by: 1.

Convergence is the ability to maintain fixation on an oncoming object. It is essential to stability of vision, depth perception and binocular vision.
Lack of convergence will have a negative influence on reading, copying from board to paper, copying paper to paper, driving and participating in. VS LABORATORY VII: FIXATION DISPARITY. INTRODUCTION. Under binocular viewing, subjects generally do not gaze directly at the visual target. Fixation disparity is defined as the difference between the target vergence angle (binocular parallax) and the ocular converence angle during binocular fixation, as shown in Fig.

To maintain balance and navigate space in our physical world, we must organize and integrate information from the visual (eyes), proprioceptive (information perceived through our muscles and joints to tell us where we are in space) and vestibular (inner ears sensing motion, equilibrium and spatial awareness) Dr.
Nathan Davis, ODFor most of us, vision is a term used. A new study, published “online first” on June 6, in JAMA Ophthalmology (formerly Archives of Ophthalmology), concludes that visually impaired individuals have a significantly greater risk of balance authors also offer suggestions to develop more effective fall prevention strategies for individuals with visual impairment or reduced visual acuity.
AFFECT VISION. The vestibular system and the visual system coordinate with each other through brain pathways in order to control visual fixation. The ‘ear to eye’ connection is known as the. vestibulo -ocular reflex (VOR). The VOR has a critical role of keeping the eyes still during head motion.
This is known as gaze stability. The VOR. This paper presents a short history of the development of fixation disparity techniques used in clinical practice and describes the occurrence and characteristics of fixation disparity in various anomalies of binocular vision, some instruments and techniques developed for the investigation of binocular vision and relief of its by: 3.

Optometric vision therapy has been shown to be an effective treatment modality for many types of problems affecting the vision system. Vision therapy services includethe diagnosis, treatment and management of disorders and dysfunctions of the vision system including, but not limited to, conditions involving binocularity.
Two Visual Pathways The focal, central or Parvocelluar visual system is called the "What" vision system. It is responsible for object identification. It allows us to focus on a specific object in the visual field.
This information is interpreted in the occipital lobe. The ambient/peripheral or Magnocellular visual system is the "Where" system responsible. Acute glaucoma: A sudden onset of severe throbbing eye pain, headaches, blurred vision, rainbow halos around lights, red eyes, nausea, and vomiting.
