To Evaluate Comparitive Values Ofapplanation, Indentation& Non-Contact Tonometry on Different Refractiveerror Groups
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 10
Abstract
AIM: To compare and contrast the objective measurement of IOP using the Schiotz indentation tonometer, Applanation tonometer and the non-contact air puff tonometer in patients with various refractive errors.MATERIAL& METHODS: A comparative study conducted on a discrete population of 150 patients all of whom attended the outpatient department of our Hospital,Maha Rani LaxmiBai Medical College, Jhansi, INDIA on a voluntary basis;150 patients were selected at random for this study ,came in opd of this medical college for period of 6 month from April 2018 toSeptember 2018.Examination of each patient included slit lamp biomicroscpe and direct ophthalmoscopic examination. Tonometric readings were taken by Goldmann's applanationtonometer, Schiotz tonometer &non-contact tonometer. REULTS: In our study 150 patients were taken & divided into 3groups on the basis of different refractive error ,one is myopic <6D ,second is myopic >6D and third is hypermetropic. In first group schiotz read highervalue more than Perkin’s&non-contact tonometer, in second group Perkin’s reads higher value than schiotz &air puff tonometer and in third group schiotz reads higher than Perkin’s & air puff tonometer. CONCLUSION; we conclude that; in patients with high myopia (> 6 Diopters) a Perkins Applanation tonometer reads higher than Schiotz and Air puff tonometer. In patients with Hypermetropia, Schiotz tonometer reads higher than Applanation and Air puff tonometer.
