Abstract

Purpose: To compare intraocular pressure [IOP] between Goldmann leveling tonometry and Diaton ballistic principle tonometry over the eyelids in different patient groups. The use of Diaton as an alternative for mass population measurements for early diagnosis of glaucoma is being studied. Method: 572 eyes of 572 patients were studied. The right eye was randomly assigned as the examination eye. The sample consisted of 54.5% women and 45.5% men of various ages. The vast majority of them are over 60 years old. The groups of patients studied are 22.7% glaucomatous, 24% with age-related macular degeneration, 21.8% diabetic and 43.8% are those who do not suffer from any of the above conditions and we called them healthy. Note that some suffered from glaucoma and diabetes and thus were counted in both groups. Intraocular pressure was measured in both eyes of all the above patients except for 2 of them in whom it was measured in only one eye. All eyes underwent IOP measurement with both Goldmann and Diaton. The values of the measurements were recorded. The Goldmann measurements were performed by the same physician without knowing the results of the Diaton measurements. As well as the measurements using the Diaton method was conducted by the same doctor and always in the same way. The measuring positions used during the examination with the Diaton are sitting or supine. Results: A statistically strong correlation was found between the measurements of the 2 tonometers (p
