Abstract :

TITLE: To evaluate comparative values of schiotz and applanation tonometry on patients of different age groups.PURPOSE:To Compare two different methods of intra ocular pressure measurement regarding reliability,accuracy and reproducibility of given methods for screening purpose. MATERIALS AND METHODS:From the out patient attendance of DEPARTMENT OF OPHTHALMOLOGY in PANDIT DEENDAYAL UPADHYAY GOVT. HOSPITAL AND MEDICAL COLLEGE,RAJKOT,300 patients were selected at random for this study.Examination of each patient included slitlamp biomicroscpe and direct ophthalmoscopic examination. Tonometric readings were taken by Goldmann�s applanation tonometer, Schiotz tonometer.RESULT AND DISCUSSION:In this study the comparative data obtained on applantion and schiotz tonometer were compared.Schiotz tonometry under estimates the pressure ranging between 16–30 mmHg and overestimates the pressure ranging between 0–15 mmHg.Schiotz tonometer cause decrease in readings of intraocular pressure due to tonographic effect,while multiple readings have no effect on readings taken by goldmann�s applanation tonometer.CONCLUSION:Goldmann�s applanation tonometry is the more reliable,reproducible, method of measuring intra ocular pressure than schiotz tonometer
