Fluorescein angiographic defects of the optic disc in ocular hypertension
M. Loebl and B. Schwartz
Fluorescein angiograms of the optic disc were studied in 23 normal and 29
ocular hypertensive eyes. Significant differences in the frequency
distributions of areas of defects were obtained between normal and ocular
hypertensive eyes. Increased areas of filling defects were noted in ocular
hypertensive eyes as compared to normals. There were also significant
correlations of the areas of filling defects with age and systolic blood
pressure in the ocular hypertensive eyes that were not present in the
normals. These observations support the concept that fluorescein
angiography of the optic disc demonstrates localized areas of impaired
circulation that increase with ocular pressure, age, and systolic blood
pressure. This technique may be useful in separating normal from the ocular
hypertensive patient who shows changes in the circulation of the optic disc
with increased ocular pressure.
