The measurements were made in the occipital visual cortex, assessing the response to the binocular and monocular stimulation.Results: 12 out of 12 patients showed an increased cortical response of the healthy eye in comparison to the amblyopic one. Nine of the 12 patients showed larger cortical activation with visual stimulation of the healthy eye compared to the binocular condition analysis. Three out of the 12 cases had a greater activation area when the stimulation was binocular rather than monocular, 2 of whom had a relatively small angle of strabismus.Conclusions: Patients with amblyopia and strabismus could see better with only one eye instead of both eyes. This could be related to inhibition of the binocular function of the brain by the misaligned amblyopic eye.","PeriodicalId":79564,"journal":{"name":"Binocular vision & strabismus quarterly","volume":"24 4","pages":"222-7"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"28587102","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}

The preoperative 3D-VOG shows hypotropia of the left eye (22.5 degrees), minimum exotropia and intorsion together with limitation in the elevation of the left eye with positive passive duction test and pseudoptosis.Results: Surgery was carried out in three stages: 1. Recession of the superior rectus of the right eye (RE) resulting in an improvement in the elevation and the pseudoptosis; 2. Recession of the inferior rectus of the left eye (LE), with improvement in the elevation of the LE but deterioration of the pseudoptosis; 3. Resection of the inferior rectus of the RE which improves both the elevation as well as the pseudoptosis of the LE.Conclusions: We consider the usefulness of the innervational techniques in the incomplete third nerve paralysis with important affectation in the elevation, making it necessary to check and in this case eliminate the restrictive effects although this may influence the effect on the pseudoptosis.","PeriodicalId":79564,"journal":{"name":"Binocular vision & strabismus quarterly","volume":"24 3","pages":"157-62"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"28420067","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}

However, there remain concerns about the effectiveness and complications when, as in this case, there are not standardized treatment protocols.Methods: A retrospective chart review of 133 consecutive patients in one community based ophthalmology practice treated for amblyopia was performed. Treatments evaluated were occlusion only, atropine penalization, and combination of occlusion and atropine. Reverse amblyopia was defined as having occured when the visual acuity of the sound eye was 3 LogMar units worse than visual acuity of the amblyopia eye after treatment.Results: Improvement in vision after 6 months and 1 year of amblyopia therapy was similar among all three groups: 0.26 LogMar lines and 0.30 in the atropine group, 0.32 and 0.34 in the occlusion group, and 0.24 and 0.32 in the combined group. Eight (6%) patients demonstrated reverse amblyopia. The mean age of those who developed reverse amblyopia was 3.5 years, 1.5 years younger than the mean age of the study population, 7/8 had strabismic amblyopia, 6/8 were on daily atropine and had a mean refractive error of +4.77 diopters in the amblyopic eye and +5.06 diopters in the sound eye. Reverse amblyopia did not occur with occlusion only therapy.Conclusions: In this community based ophthalmology practice, atropine, patching, and combination therapy appear to be equally effective modalities to treat ambyopia. Highly hyperopic patients under 4 years of age with dense, strabismic amblyopia and on daily atropine appeared to be most at risk for development of reverse amblyopia.","PeriodicalId":79564,"journal":{"name":"Binocular vision & strabismus quarterly","volume":"24 1","pages":"25-31"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"28075220","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}

{"title":"The effect of testing distance on the bielschowsky head tilt test.","authors":"Rebecca L Hunn, Alison Y Firth","doi":"","DOIUrl":"","url":null,"abstract":"Aims: The Bielschowsky Head Tilt Test (BHTT) is a commonly used test in Orthoptic practice and is used mainly to differentiate between a long standing Superior Oblique and Superior Rectus palsy. No consistent test distance is recommended in the literature and therefore the aim of this study was to determine whether test distance had an effect upon the measurements obtained.Method: Thirteen participants were recruited. Participants had either longstanding or recent onset unilateral Superior Oblique palsy. Prism Cover Test measurements of the vertical angle of deviation were taken whilst the participant tilted their head to either side whilst fixating on a target at 33 cm, 3 m and 6 m.Results: The test distance does have a significant effect on the change in vertical angle measured with head tilted to either side (x2+7.747,DoF 2, p=0.021). When the median values are considered it appears that the significant effect occurs due to a smaller change in angle between head tilt to the affected side when fixing at 3 metres. This was confirmed using the Wilcoxon signed rank test (33cmv3m p=0.039, 3m v 6m p=0.013 and 33cm v 6m p=0.67).Conclusions: The testing distance at which the BHTT is performed appears to have an effect upon the measurements obtained. The clinical importance of the difference in the change of angle with head tilt to either side is debatable due to the fact that the difference in the median measurement value between the three test distances is a maximum of 3 prism dioptres.","PeriodicalId":79564,"journal":{"name":"Binocular vision & strabismus quarterly","volume":"24 1","pages":"33-8"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"28075221","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}
