We measured apparent accommodation in 42 pseudophakic eyes (34 patients) after implantation of posterior chamber intraocular lenses. The mean apparent accommodation was 2.03 +/- 1.03 diopters. The mean accommodative power of 16 phakic eyes used as controls was 2.91 +/- 1.29 diopters. The diameter of the pupil appeared to be the most important factor in apparent accommodation--the smaller the pu...

BACKGROUND There is abundant evidence of the affordable, life-saving interventions effective at the local primary health care level in low- and middle-income countries (LMICs). However, the understanding of how to deliver those interventions in diverse settings is limited. Primary healthcare services implementation research is needed to elucidate the contextual factors that can influence the ou...

L'insertion de corps étrangers intrarectal reste dans notre contexte, une curiosité et un tabou. Elle est le plus souvent volontaire par trouble du comportement, pour des fins sexuelles (érotisme ou agressions), pour auto-traiter une constipation ou pour dissimuler l'objet (drogues, etc). Elle est rarement accidentelle. Ces corps étrangers peuvent être de nature très diverse et insolite. L'extr...

Patient and family experiences are important indicators of quality of care and little is known about how family accommodation affects hospital experience. We added questions about accommodation to standardized inpatient pediatric and neonatal intensive care unit family experience surveys at 10 U.S. hospitals to determine the accommodation types used by families, compare characteristics across a...

Although contour rivalry is known to suppress the contribution of the non-dominant eye to some visuomotor mechanisms such as the pupillary light reflex, there have been no reports of the impact of rivalry on accommodation control. In the situation where the accommodation demands in the two eyes are in dynamic conflict, it has been reported that the accommodation response can be modelled in term...

This review was undertaken to address concerns raised by the US Army Corps of Engineers (Corps) regarding the value of projects authorized to improve environmental quality. Value gained from present resource use can typically be measured in monetary terms. More controversial -and prohibited by Corps policy -is the monetary measurement of the nonuse value gained by deferring present-day use in f...

PURPOSE To define the long-term results of accommodation insufficiency and to investigate the correlation between accommodation insufficiency and other factors including near point of convergence (NPC), age, and refractive errors. METHODS From January 2008 to December 2009, 11 patients with acute near vision disturbance and remote near point of accommodation (NPA) were evaluated. Full ophthal...

PURPOSE The relative efficiency of different eye exercise regimes is unclear, and in particular the influences of practice, placebo and the amount of effort required are rarely considered. This study measured conventional clinical measures following different regimes in typical young adults. METHODS A total of 156 asymptomatic young adults were directed to carry out eye exercises three times ...

Steady-state accommodation responses were measured in both eyes as a function of vergence angle and direction of lateral gaze. The measurements were made with a binocular laser optometer. Small speckle patterns were used as fusional stimuli in an otherwise dark field. These patterns have the advantage of providing no blur stimulus to accommodation. Convergence accommodation for vergence angles ...
