We report 2 bilateral cases that presented as primary ocular hypertension and primary angle-closure glaucoma, respectively; however, they were subsequently discovered to be harboring secretory pituitary tumors. After transsphenoidal tumor resection, intraocular pressures (IOPs) in all 4 eyes returned to normal levels. Sudden rise in IOP then again served as a primary manifestation of relapse in the second patient with growth hormone secreting pituitary tumor. It was not found feasible for resurgery; thus, patient needed trabeculectomy in both eyes to achieve an optimum control of intraocular tension. We conclude that pituitary adenomas may mimic primary glaucoma without producing vertical hemianopia and cause a reversible rise in IOP. Furthermore, a careful ongoing expert ophthalmologic assessment may serve as a useful clinical marker for early relapse in these tumors.
