The evaluation of chronic glaucoma begins with a medical history and eye examination.

Physical findings in someone with chronic glaucoma may include:

• Abnormal retina
• Abnormal visual acuity

The diagnosis must be confirmed through testing.

Tests that may be used to evaluate chronic glaucoma include:

• Perimetry:
• Checking the entire visual field for defects
• Funduscopic examination:
• Normal retina
• Glaucoma retina
• Gonioscopy:
• Using a special lens to examine the areas of the eye that drain fluid to keep the pressure within the eye normal.
• Measurement of the pressure within the anterior chamber of the eye
• Visual acuity measurement
