In 24 ocular hypertensive patients, two optic disc fluorescein angiograms were obtained a mean of 3.9 years apart. Using computerized image analysis, we measured the area of pallor and the fluorescein-filling defect area within the disc and the fluorescein circulation parameters representing the filling rates of optic disc, choroid, and retinal vessels. The results indicated that increase in pallor and fluorescein-filling defect areas, as well as a slowed filling rate of the retinal veins, correlated with glaucomatous progression.

The ocular hypertensive eyes showed significant increases in pallor but not in cupping compared to normal eyes. There was also a significant positive correlation of cupping with age in normal eyes but not in ocular hypertensive eyes.

September 1980
A comparison of two or more disc fluorescein angiograms performed on separate occasions was done on 60 eyes of normal subjects and patients with ocular hypertension, primary open-angle glaucoma, and low-tension glaucoma. Clinically stable patients did not show any change in their disc angiographic filling patterns. Eyes that developed new visual-field defects with increased disc cupping and pallor correspondingly showed new absolute filling defects or areas of hypofluorescence.

Arch Ophthalmol
August 1980
The two-point fluorophotometry technique was used to analyze quantitatively absolute fluorescein filling defects or hypofluorescent areas in glaucomatous optic discs. Significant differences were found between hypofluorescent and normal fluorescent areas. The hypofluorescent areas had slower and lesser filling of fluorescein and a slower disappearance of fluorescein compared with normal fluorescent areas.
