An herb more commonly known as butcher's broom, ruscus aculeatus is traditionally used for circulation and appears to constrict veins this is thought to reduce pooling of blood in extremities, and the limited evidence appears to be promising.

Convergence insufficiency results from research studies show that about 1 out of every 20 people (5%) have convergence insufficiency most studies have been conducted with school age children or adults and show that the prevalence of convergence insufficiency is similar across all populations.

Insufficiency of accommodation in patients with advanced aids this study determined the amplitude of accommodation in patients with advanced acquired immunodeficiency syndrome (aids) the push-up and minus lens techniques were used to measure the accommodation amplitude of 42 patients with aids, aged 17 to 44 years, and of aged. In 2008, the citt study group reported a randomized controlled trial (rct) of 221 children (9-17 years of age) with symptomatic convergence insufficiency(10) the children were randomly assigned to 1 of 4 treatment conditions: home-based pencil push-ups home-based computer vergence/accommodative therapy and pencil push-ups weekly office.

Abstract the aim of this work was to study the relation between subjective symptoms at near and ocular accommodation in terms of the amplitude of accommodation and the relative accommodation. A pilot study of disparity vergence and near dissociated phoria in convergence insufficiency patients before vs after vergence therapy front hum neurosci 2015 9:419. Purpose the objectives of the present study were to evaluate whether investigator bias influenced the convergence insufficiency symptom survey (ciss) scores of children with normal binocular vision (nbv) in our original validation study, reevaluate the usefulness of the cutoff score of 16, and reexamine the validity of the ciss methods. In addition, the binocular accommodative amplitude improved, whereas the monocular amplitude did not it is likely that the measurement of the binocular accommodative amplitude in subjects with ci is more of a measure of npc than of accommodation, since their reduced disparity vergence mechanism is likely to result in the fixation target’s.
