Abstract :

TITLE: To evaluate comparative values of non contact 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 PANDEET 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, Non contact tonometer. RESULT AND DISCUSSION: In this study the comparative data obtained on applantion and non contact tonometer were compared. noncontact tonometry can be used for screening purpose as it gives reliable values compared to goldmann�s applanation tonometer for the pressure ranges between o-15 mmHg. Non contact tonometry had a tendency to overestimate very high pressures and under estimates at law pressure. CONCLUSION: Goldmann�s applanation tonometry is the more reliable and reproducible method of measuring intra ocular pressure than non contact tonometer.
