The Use of HRT II in Glaucoma Prevention

Overview

Altogether 2436 eyes of 1218 healthy persons from the ophthalmological point of view were examined in the screening glaucoma action by means of Heidelberg Retinal Tomograph (HRT II). In 103 persons (8.5 %), the result of the examination was at least in one sector of the optic nerve head graded as “suspicious” of “out of normal range”. In those individuals, the complete ophthalmological examination including visual field examination with the Humphrey perimeter Threshold 24-2 program was performed. Monocular changes in HRT II examination were noticed in 83 patients (in 24 out of them also visual field changes were noticed), while bilateral changes in HRT II examination were noticed in 20 persons (in 5 of them also changes in the visual field). Medical treatment of glaucoma was started immediately after the complete examination in 10 persons, in 6 others the treatment started after next 12 months. The remaining 87 persons (7.1 %) with the abnormal finding in the HRT II examinations are followed up. The HRT II use for the glaucoma screening helped to make the diagnosis of this disease in the early stage in 16 persons (1.3 %), who probably will not otherwise visit the ophthalmologist.
