Presentation Transcript

  1. Surgeon Ophthalmologist? Physician

  2. Anterior surgeon Posterior surgeon Ophthalmology • Oculoplasty • Cornea Glaucoma • Retina • Strabismology • Neuroophthalmology • Ocular pathology

  3. Modern Intraocular Surgery Inflow Microcomputer outflow

  4. Modern strabismology Modern Neuroophthalmology Some Sensorial Aspect of Strabismus that interest Me.

  5. Confusion Diplopia or suppression Diplopia

  6. Suppression

  7. Amblyopia • Strabismic Amblyopia : inhibition by cortical competition between dissimilar images • Anisometropic Amblyopia : Abnormal binocular interaction Deprivation of form vision • Visual Deprivation Amblyopia

  8. Anomalous Correspondence Objective Location Subjective localization

  9. Infantile Esotropia • Amblyopia • Upshoot or downshoot on adduction • DVD/DHD • Manifiest-latent nystagmus • Asymmetric OKN • Large angle(over 30 prism) • Stable angle(may increase) • No apparent CNS involvement

  10. Primary Exodeviations • Exophorea • Intermittent Exotropia • Constant Exotropia • Progress : suppression

  11. Dissociated Vertical Deviation

  12. Mechanisms of stereoscopic vision: the disparity energy model Izumi Ohzawa Current Opinion in Neurobiology 1998, 8: 509-515

  13. Introduction • Barlow et al.: Neuronal response : Tune to variety of stereoscopic depths. Farther or on the fixation plane or closer • Poggio et al : V1 V2 complex cell respond to DRDSs. Only second stage of visual cortical processing

  14. The correspondence problem False matches Two-dimensional map

  15. Binocular RF mapping Method

  16. Disparity Energy Model

  17. Energy landscape Multiple disparity tuning curve Energy landscape Perception of depth !

  18. Energy landscape and strabismus The Normals The Strabismics
