Psychological Stress and Intraocular Pressure in Glaucoma: A Randomized Controlled Trial.

Purpose: To evaluate the intraocular pressure (IOP) behavior after applying a standardized protocol to induce psychological stress in patients with primary open-angle glaucoma (POAG).

Design: Randomized controlled trial.

Participants: A total of 39 patients with POAG were included: 18 in the stress group and 21 in the control group.

Comparison of variation of intraocular pressure in noncontact tonometry in patients subjected to phacoemulsification and trabeculectomy with phacoemulsification.

Objective: Evaluate the pattern of intraocular pressure (IOP) variations through the pneumatic tonometer, between two specific surgical techniques, and the possible variables that may influence the behavior of this pressure.

Methods: Retrospective cross-sectional study carried out through the review of electronic medical records of a private ophthalmological reference hospital in the city of Goiânia, Goiás, Brazil, from 2012 to 2016, comprising of a sample of 550 eyes. The analyzed variables were, age, gender, IOP, axis, pachymetry, anterior chamber depth, and axial length.
