FIGURE 2. Figures 2 and 3 illustrate the importance of the translaminar pressure gradient in a patient who developed profound optic disc edema following surgical IOP lowering in the left eye and was subsequently diagnosed with pseudotumor cerebri (idiopathic intracranial hypertension). The optic nerve in the fellow eye was protected from optic disc edema due to elevated IOP. The optic disc edema resolved following administration of oral acetazolamide therapy.
