Visual and Endocrine Recovery Following Conservative and Surgical Treatment of Pituitary Apoplexy: A Meta-Analysis

Abstract

Background: Pituitary apoplexy (PA) can manifest with visual and endocrine defects. The literature lacks strong support for either surgical or conservative management with respect to symptomatic improvement of these deficits. This meta-analysis compared visual and endocrine outcomes in conservative and surgical treatment of PA.

Methods: A systematic literature search was performed in PubMed, Cochrane, and Ovid MEDLINE for articles published between 1988 and 2018. Recovery outcomes were binarized, such that complete and partial improvements were combined as "improvement." Primary outcome variables evaluated via a binary random-effects model were improvements in endocrine dysfunction, visual field and acuity deficits, and ophthalmoplegia or ocular nerve palsy.

Results: Of 483 published articles, 14 studies comprising 457 cases (259 surgical treatments and 198 conservative treatments) were included. On initial examination, 58% of patients had endocrine dysfunction, 37% had visual acuity or field deficit, and 47% had ophthalmoplegia or ocular nerve palsy. Evaluation of outcomes for surgically and conservatively treated patients yielded odds ratios of 0.609 (95% confidence interval [CI], 0.199-1.859; P = 0.383), 0.763 (95% CI, 0.307-2.374; P = 0.763), 1.167 (95% CI, 0.433-3.146; P = 0.760), and 0.801 (95% CI, 0.305-2.105; P = 0.653) for improvements in endocrine dysfunction, visual acuity dysfunction, visual field dysfunction, and ophthalmoplegia or ocular nerve palsy.

Conclusions: Both surgical intervention and conservative management of PA can lead to visual and endocrine recovery, although the management decision may heavily rely on severity of initial deficits. Treatment of PA can be multifaceted and tailored to the individual case and clinical judgment. Further investigation into appropriate intervention based on longitudinal outcome data is warranted.
