Objective: To evaluate the feasibility of short automated static perimetry
using tendency-oriented perimetry in the pediatric population,
Design: Prospective observational case series.
Participants: Fifty normal children age 6 through 12 years.
Testing: Subjects underwent testing with the Octopus TOP-32 program on the
Octopus 1-2-3 automated perimeter, Testing was performed in a typical clini
cal setting without adaptations to the perimeter, prolonged training, or th
e use of custom seating. Each eye was tested twice.
Main Outcome Measures: Ability to complete automated static perimetry tests
with both eyes. Mean sensitivity, mean defect, and loss of variance; gray
scale and numeric representations of the field; duration of each test and o
f the entire session; subjective assessment of each test as normal or abnor
mal; calculation of test specificity. Comparisons by age and test number we
re performed.
Results: All subjects successfully completed all four tests. The mean durat
ion for each test was 2:30 +/- 0.23 minutes. The average time for the whole
session, including training, testing both eyes twice, and rest periods, wa
s 25.8 +/- 4.87 minutes. Improvement in the specificity of the test (fewer
abnormal tests in normal children) occurred in direct relation to subject a
ge (R = 0.5).
Conclusions: Automated static perimetry using short, tendency-oriented prog
rams can be successfully performed in normal children age 6 through 12 year
s in a typical clinical setting. Age was the best predictor of the mean sen
sitivity, reproducibility, and accuracy of the test, with the most reliable
results obtained after 7 years of age. In children 6 to 7 years old, signi
ficant interindividual variability was present, and testing success was mor
e dependent on the child's maturity and ability to concentrate. Short autom
ated perimetry seems to be a promising tool for the evaluation of periphera
l vision in pediatric patients. Ophthalmology 2001;108:157-162 (C) 2001 by
