Automated Static Perimetry

Abstract

PART ONE: BASICS 1. Introductory Concepts Anatomy and Function of the Eye Visual Field Correspondence of the Retina and Visual Field Boundaries of the Visual Field 2. Basis of Quantitative Perimetry Visual Characteristics Within the Visual Field Units of Light Intensity Threshold Sensitivity in Terms of Stimulus Intensity Frequency-of-Seeing Curve and Short-Term Fluctuations Long-term Fluctuation Subjective Stimulus Brightness Background Intensity Contrast Sensitivity and Veiling Glare Refractive Error and Retinal Blur Stimulus Size and Spatial Summation Temporal Summation and Stimulus Deviation Learning Effects Fatigue Effects Kinetic and Static Stimuli Chromatic Perimetry Other Types of Perimetry 3. Topographic Classification of Visual Field Defects Anatomical Basis Prechiasmal defects Postchiasmal Defects Stato-kinetic dissociation (Riddoch Phenomenon) 4. Visual Field Loss in Glaucoma Local and diffuse loss Anatomic basis of nerve fiber bundle pattern Hemifield asymmetry and nasal steps Point of Fixation Generalized Depression Summary and Examples PART TWO: OFFICE PERIMETRY 5. Clinical Static Perimetry Basic Goals Mainstream Perimetric Protocols The Original, Classic Central Static Threshold Test New Thresholding Algorithms Determining Test Reliability Current Thresholding Algorithms: Summary Suprathreshold Tests Structuring the Test Conditions 6. The Single Field Printout Basic Identification Reliability Parameters Questions and test time Raw Test Results Total Deviation (From Normal Values For Age) Pattern Deviation (Localized Loss) Global Indices Plain Language Analysis 7. Interpretation of a Single Field Reliability Is The Field Abnormal? How Advanced Is The Disease? Artifacts 8. Selection of Automated Tests Glaucoma Diagnosis in the Office Population Screening for Glaucoma Following the Patient with Glaucoma Neurologic Conditions Retinal Diseases Blepharoptosis Driving Qualification Visual Impairment and Disability Programs That are Obsolete or Rarely Used 9. Follow-Up Examinations Establishing a Baseline Follow-up Visual Field Examinations An Overview Change Analysis Printout Pointwise Changes Interpretation Conclusion 10. Alternate and Supplemental Techniques Amsler Grid Confrontation Techniques PART THREE: TECHNIQUE 11.
