Can tight necktie be a risk factor in development and progression of primary- Open Angle Glaucoma (POAG)?
Abstract
neckties on intraocular pressure (IOP)measurement using Perkins applanation tonometry method. Eighty eyes of normal 40 subjects and 40 primary open angle glaucoma patients were enrolled. IOP, blood pressure and pulse rate were measured with an open shirt collar and 5 minutes after placing a tight necktie.
All measurements were made by the same examiner. The results showed significant (P <0.05) increase of IOP after a tight necktie in both groups, irrespective of sex. Thus optometrists should advice patients to remove tight neckties before IOP measurements.
