Premium member Presentation Transcript PowerPoint Presentation: Etiology of Heterophoria and Heterotropia Dr. Huseynova T. Briz-L Eye Clinic, Baku, Azerbaijan Chairman of ADMO YO www.admo.org.az tukezban@gmail.comPowerPoint Presentation: Orthoforia occurs where both visual axes are directed towards the fixation point and do not deviate on dissociation.PowerPoint Presentation: Factors that determine the relative position of the visual axes. Anatomical factors . Innervational factors.PowerPoint Presentation: Factors Responsible for the Manifestation of a Deviation Abnormalities of Fusion Mechanism Reflexologic TheoriesPowerPoint Presentation: HeterophoriaPowerPoint Presentation: Where heterophoria is presented, both visual axes are directed towards the fixation point but deviate on dissociation.PowerPoint Presentation: Classification. Esophoria - convergence excess - divergence weakness - non-specific Exophoria - conveargence weakness - divergence excess - non-specific Hyperphoria/hypophoria Alternating hyperphoria/hypophoria CyclophoriaPowerPoint Presentation: Aetiology. Esophoria Anatomical – enophthalmos, narrow IPD, extraocular muscle anomalies Refractive – suprable hypermetropia, anisometropia High AC/A ratio Weak negative fusional reservesPowerPoint Presentation: Aetiology. Exophoria Anatomical – exophthalmos, wide IPD, extraocular muscle anomalies Refractive – acquired myopia, presbyopia, anisometropia Weak positive fusional reserves Passage of timePowerPoint Presentation: Aetiology. Hyperphoria/hypophoria Refractive – high myopia (heavy eye syndrome) Weak vertical fusional reserves Anatomical – displaced globes, abnormal extraocular muscles, ptosisPowerPoint Presentation: HeterotropiaPowerPoint Presentation: Heterotropia is a condition in which one or other visual axis is not directed towards the fixation point.PowerPoint Presentation: There are a number of different forms of heterotropia: Esotropia Exotropia Hypertropia Hypotropia Cyclotropia Dissociated vertical deviation (DVD) Dissiciated horizontal deviation (DHD)PowerPoint Presentation: Factors Causing the Deviation . Mechanical factors Structural anomalies of extraocular muscles Accommodation and refraction in comitant strabismus Fixation disparity Previous eye surgeries or brain surgeriesPowerPoint Presentation: Factors Causing the Deviation . Other Innervational (Neurologic) Factors in Comitant Strabismus. Paretic elements Anomalies of the brainstem Anomalies of convergence and divergence Vestibular system Anomalies of the visual pathway Brain damage EmbryopathyPowerPoint Presentation: Thank You You do not have the permission to view this presentation.
