Introduction to Automated Static Perimetry1

Automated perimetry is the current gold standard to diagnose glaucoma and its management. The main aim of this book is to make the ophthalmologist to understand the basic fundamentals of automated static perimetry, to select the most appropriate test to the clinical condition he is dealing with, to understand the visual field printouts and to interpret the printouts without much difficulty so that he should be able
  1. To identify a field defect.
  2. To decide whether the field defect is due to glaucoma.
  3. To make a reasonable decision whether the defect is progressive one or not.
 
 
 
Reasons for Computerized Perimetry
  1. Reproducible testing conditions.
  2. Data-storage capability: Results can be compared overtime and analyzed using expert system software.
  3. More sensitive testing: Many researchers claim static perimetry to be superior to kinetic perimetry to identify defects.
  4. Easy operation and menu driven software make automated perimetry easy to learn and to use.
 
History
1970 -
The original octopus perimeter was first introduced. Because of its room size and high expensive nature it became unpopular.
1982 -
Humphrey field analyzer was first displayed at American Academy of Ophthalmology.
1983 -
August- Michael Patella showed its first clinical trail.
1984 -
February- started production and became very popular because of its small size and affordable price.
