Abstract

As accommodation and repeated tonometry were known to change the level of intraocular pressure, sometimes they may give a misleading indication for the diagnosis and management of early glaucoma, ocular hypertension and low tension glaucoma. The object of this study was to investigate the effects of accommodation and repeated tonometry on intraocular pressure in Korean adults. Repeated tonometry was performed on 120 normal Korean eyes with visual acuity of 20/20 or more under controlled condition of accommodation and relaxation using Goldmann applanation tonometry and Schiotz tonometry. The results were as follows: 1. In repeated Goldmann applanation tonometry, a statistically significant reduction in mean intraocular pressure was produced during accommodation but not during relaxation. The maximum reduction of 3.25mmHg was produced during four minutes of accommodation and significant reduction of 2.01 mmHg was shown in first one minute of accommodation. 2. In repeated Schiotz tonometry, a statistically significant reduction in mean intraocular pressure was produced during accommodation but not during relaxation. The maximum reduction of 3.71mmHg was produced during four minutes of accommodation and significant reduction of 2.39 mmHg was shown in first one minute of accommodation.
