FIGURE 2.

Stereoscopic optic disc photographs of the right (upper) and left (lower) eyes of a glaucoma suspect. Intraocular pressures ranged between 14 and 20 mm Hg in the right eye and 16 and 32 mm Hg in the left eye before treatment. On medical therapy, pressures ranged between 10 and 18 mm Hg in the right eye and 13 and 20 mm Hg in the left eye. The patient has been followed for more than 15 years while on therapy without progression. Note the mild cup-disc asymmetry with the left cup being slightly larger than the left despite equal optic disc sizes.
