Patients with intermittent exotropia and exophoria plus ortho subjects underwent measurement of saccadic reaction times (SRTs) to compare those occurring in one eye and those occurring with alternating cover tests (ACTs). Twenty-five subjects were studied. Results for the intermittent exotropia...
The purpose of this study was to evaluate the effectiveness of orthokeratology (OK) lenses with an increased comparison factor (ICF) of 1.75D in the treatment convergence insufficiency (CI) exophoria (EP). This was a prospective, self-controlled study of 60 eyes (30...
"My friend wanted to show how far he could throw that log. So, he helicoptered it over his head, faster and faster and when he let go, it hit my eye at full speed,” a young lady of 19 years...
Orthoptists see a wide range of conditions that can range from reduced binocular single vision (BSV) that may be solved with exercises, to more extreme neurogenic cases requiring further intervention. Because of this variety, it is important to be able...
Although respiratory symptoms are the most frequent manifestation of COVID-19, multi-organ involvement has been demonstrated, including ocular manifestations. The author investigates how the eye can be affected. The SARS-CoV-2 virus responsible for the COVID-19 pandemic has presented a significant public...

The aim of this study was to investigate the frequency of accommodative and convergence disorders in an optometric clinical population and ascertain tests with the highest sensitivity and specificity in detecting these anomalies. The authors gathered information on symptoms, near...
A retrospective study was conducted to compare the efficacy of medial rectus recession and lateral rectus resection as surgical interventions for divergence insufficiency in 18 patients. These were cases of non-neurological cause. Two patients in each group required postoperative adjustment....
Three groups of subjects were included in this study. Group 1 had typically developing children from five to nine years with heterophoria less than 6PD. Group 2 had 19 children aged five to nine years with intermittent distance exotropia. Group...
In this study the authors evaluate the accuracy and sensitivity of the Plusoptix S08 photoscreener in detecting strabismus problems in 83 patients aged from six months to 40 years (mean 105 months). A pass was achieved for 25 patients and...
This study was designed to investigate the effect of induced vertical disparity by prisms on horizontal fusional reserves at near distance. One hundred and seventy students were recruited and vertical disparity was induced by small vertical prisms of 0.5 and...
