BACKGROUND Amblyopia and its risk factors have been demonstrated to be more common among children from low socioeconomic backgrounds. We sought to investigate this association in a region with orthoptic-delivered screening and whole population coverage, and to also examine the association of the Health Plan Indicator (HPI) with screening outcome. METHODS Screening examination outcomes, postco...
We hypothesize that binocular coordination of saccades is based on continuous neuroplasticity involving interactions of saccades and vergence. To test this hypothesis we study reading saccades in young students who were diagnosed for vergence disorders before and after vergence rehabilitation. Following orthoptic evaluation and symptomatology screening, 5 weekly sessions of vergence rehabilitat...
The purpose of this study was to investigate the incidence, etiology, treatment modalities, morbidity and types of diplopia in zygomatic complex fracture. Fifty patients with zygomatic-complex fractures who had attended the out-patient review clinic at Manchester Royal Infirmary in Manchester United Kingdom formed the study group. Information for the study was gathered from patient records from...
Fixation disparity is a minute ocular misalignment under conditions of binocular single vision and is typically detected in primary eye care practices in the UK using the Mallett Unit Fixation Disparity Test. This instrument creates natural viewing conditions, when the patient's binocular system is fused using both central and peripheral fusion locks. This allows the examiner to determine the m...
30 patients of intermittent ACDS were studied prospectively for a period of 8 weeks to 1 year to evaluate the role of orthoptics in the management of these cases. In patients with convergence insufficiency and a maximum deviation of 25 PD or less the orthoptic treatment was found to be effective in offering symptomatic relief and improving binocular functional status. A reduction in the maximum...
[TOP] Office-based vergence/accommodative therapy may be considered medically necessary for patients with symptomatic convergence insufficiency if, following a minimum of 12 weeks of home-based therapy (e.g., push-up exercises using an accommodative target; push-up exercises with additional base-out prisms; jump to near convergence exercises; stereogram convergence exercises; recession from a t...
Prior studies have pointed toward a link between the saccadic and vergence systems, coordinating binocular saccadic movements. Recent studies have shown that vergence deficits in children induce poor binocular coordination during saccades, but none of them have studied ocular motility in children during a daily task such as reading. The present study tests whether vergence deficits in children ...
We recently reported acuity development in the amblyopic eye of a 60-year-old patient after loss of vision in her non-amblyopic eye. Here, we focus on the training that we implemented, based on new insights from psychophysical procedures aiming at functional visual improvement of adults ("perceptual learning"). We alternately used the following procedures: grating acuity (Teller-Cards); contras...

Anisometropy as a first step on a way forward future amblyopic child, can be prevent and treat if this condition is recognased on time. Second step is wisdom, right contact lens fit on bothes eyes. As follow, some ortoptic-pleoptic procedures depending on (objective, subjective squinting angle, state of fusion, visus on bothes eyes and separatly each eay and condition of nervus opticus (VEP), n...
