Convergence Excess: Characteristics and Treatment
American Orthoptic Journal, 1999Convergence excess esotropia may result from a high AC/A ratio (accommodative convergence excess), abnormally high proximal convergence (non-accommodative convergence excess), or decreased accommod...

Treatment of Convergence Excess Esotropia: Prism Adaptation
American Orthoptic Journal, 1998Difficulties involved in effectively treating convergence excess esotropia have prompted the extension of the use of prism adaptation to patients with this type of strabismus.

Suppression Associated With Esotropia With Convergence Excess (High AC/A Ratio)
Documenta Ophthalmologica, 1984With binocular perimetry suppression was found for near vision in patients with esotropia with convergence excess, whereas fusion was present for distance. If a bitenuporal stimulation was obtained by means of base-out prisms, diplopia was elicited instead.

The Management of Esotropia With High AC/A Ratio (Convergence Excess)
Journal of Pediatric Ophthalmology & Strabismus, 1985ABSTRACT This paper reviews the long-term follow-up of esotropia with a high AC/A ratio defined as an increase of 20Δ or more of the esotropia at near compared with distance with the full optical correction of any refractive error in place. Ninety-nine patients were studied for an average followup of eight years. Eighty-six achieved

Preoperative prism adaptation in acquired esotropia with convergence excess
Journal of American Association for Pediatric Ophthalmology and Strabismus (JAAPOS), 2003The prism adaptation test (PAT) is used preoperatively to determine the surgical target angle for acquired esotropia. We assessed the surgical outcomes for children with convergence-excess esotropia (near esotropia greater than distance esotropia by 10 prism diopters [PD] or more) whose target angle was based on the results of the PAT geared to the ...

The causes of cyclic excessive convergence at the longwall tailentry
International Journal of Mining Engineering, 1983Longwall panel layouts in the USA differ from other countries in that each panel is blocked out at both sides by at least three parallel panel entries separated by chain pillars. The panel entries may vary in width up to 90 m depending on local conditions.

Modified Y- split and recession of medial rectus muscles in convergence excess esotropia
European Journal of Ophthalmology, 2020Purpose: The convergence excess esotropia (CEET) is defined when near esotropia is greater than the distance by at least 10 PD while the eye is corrected with the full cycloplegic refraction. The purpose of this study is to evaluate the effect of a modified technique of Y- split recession of the medial rectus ...

Slanted Medial Rectus Recession Is Effective in the Treatment of Convergence Excess Esotropia
Journal of Pediatric Ophthalmology & Strabismus, 2014Purpose: To evaluate the surgical outcomes of slanted medial rectus recession in patients diagnosed as having convergence excess esotropia. Methods: Bilateral slanted recession of medial rectus muscles was performed in 16 patients with convergence excess esotropia. The lower margins

Aspheric Contact Lenses Used to Control Convergence Excess
Australasian journal of optometry, The, 1993A 15-year-old female patient presented wearing progressive addition spectacle lenses to help control a condition of convergence excess. She was fitted with aspheric, multifocal, rigid gas permeable contact lenses for cosmetic reasons. The lenses were fitted 1.5 dioptres steeper than the flatter keratometer reading, and incorporated an eccentricity ...
