A comparative study of visual field defects seen in patients with low-tension glaucoma and chronic simple glaucoma.

In a study comparing the visual field defects of patients with chronic simple and low-tension glaucoma differences in the nature of the defect were found between the 2 groups. Patients with low-tension glaucoma had far 'steeper sided' defects than those seen in chronic simple glaucoma (p less than 0.01).
