The current prospective randomized trial evaluates the diagnostic specificity of the CISS. Patients and Methods Surveys were completed by 118 adolescent patients who presented for routine eye examinations. Scores were compared between patients who could be classified as having convergence insufficiency (CI) or normal binocular vision (NBV). In addition, a comparison was done between self- and practitioner-administered CISS scores within these groups. Results The mean CISS score did not differ significantly between NBV patients (14.1 ±11.3, range of 0 to 43) and CI patients (12.3 ±6.7, range of 3 to 28); P = 0.32. Mean CISS scores were lower when physician-administered (11.4 ±7.9) than when self-administered (16.3+11.4); P = 0.007.

Since its inception, October 7, 1940, approximately 90% of all certified orthoptists (C.O.) have consistently maintained membership in their professional society. Approximately 80% of AACO members attend AACO-sponsored scientific meetings at least once annually. And 17–20% of members are actively involved in AACO leadership, management, and activities. Eye care has changed dramatically over the last 75 years, and orthoptics has successfully adapted to survive due to the fortitude and resilience of its practitioners. The AACO has weathered opposition from much more powerful competitors, ever-increasing health care regulation, and an evolution in the standard management of strabismus, only to emerge transformed and even more durable. One constant remains: the qualities that inspired thirty-three individuals to create a profession and a society dedicated to the care of patients with strabismus and disorders of binocular vision, and the education of parents, orthoptists, and ophthalmologists exist in every orthoptist today.

Patients and Methods Sixty-three patients were evaluated with a new device for the measurement of exclusive visibility during binocular rivalry. The patients were consisted of twenty-three with exotropia (XT), twenty with intermittent exotropia [X(T)], twenty with exophoria (XP), respectively. Device is composed of two retinometers, their holders in which angle and position can be adjustable and a PC for data storage and analysis. In each of eyes, exclusive visibility of one stimulus during binocular rivalry was measured for 60 sec, and the strength of ocular dominance was evaluated by the difference of exclusive visibility between dominant and nondominant eye. Results The difference of exclusive visibility time between dominant and nondominant eye were 9.8 ± 3.7 sec in the XT group, 6.1 ± 4.1 sec in the X(T) group and 2.2 ±1.5 sec in the XP group, respectively. There were significant differences between XT and X(T) (P < 0.01) as well as between XT and XP (P < 0.001). Conclusions The present result indicates that sensory dominance was obviously influenced by ocular deviations since exclusive visibility of dominant eye was prolonged with decreasing the opportunity of normal binocular vision such as XT or X(T).","PeriodicalId":76599,"journal":{"name":"The American orthoptic journal","volume":"65 1","pages":"67 - 72"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3368/aoj.65.1.67","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69585114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

That term is not adequately descriptive, since this finding can occur without the patient having been allowed to fuse. The purpose of this study is to investigate the possibility that this phenomenon is mediated by the preponderance of binasal retinal disparity and uncrossed localization that occurs with near fixation. Patients and Methods Ten patients with intermittent exotropia who manifested TPF were measured at 6 m, 1/3 m, again at 1/3 m after 1 hour of monocular occlusion, and at 1/3 m with a peripheral crossed localization stimulating device (PCLSD) that simulated the retinal bitemporal disparity and peripheral crossed localization usually found with distance fixation. Results For the ten patients, the mean measurement at distance was 28.3Δ ± 3.1, initially at near was 4Δ ± 3.9, at near after prolonged monocular occlusion was 25.3Δ ±5.3, and at near with the PCLSD was 18.5Δ ± 4.1. The differences between the initial near measurement and the measurement with the PCLSD, and between the PCLSD and post-prolonged monocular occlusion were significant with P < 0.001 and P = 0.0049, respectively. Conclusions What has been previously referred to as TPF in fact appears to be convergence induced by the preponderance of binasal retinal disparity and/or peripheral uncrossed localization typically found with near fixation. For simplicity, I propose the term TPF should be replaced with the “Scobee Phenomenon.”","PeriodicalId":76599,"journal":{"name":"The American orthoptic journal","volume":"65 1","pages":"73 - 80"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3368/aoj.65.1.73","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69585155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
