Intraocular pressure measurement: Goldmann Applanation Tonometer vs non contact airpuff tonometer.
BACKGROUND An accurate assessment of Intraocular pressure (IOP) is vital in establishing diagnosis of Glaucoma and decision making regarding various treatment modalities available. The purpose of this study is to compare Goldmann Applanation Tonometer (GAT) with Air puff tonometer. METHODS Cross-sectional comparative study conducted. 73 eyes from 73 patients were included in this study and in...
متن کاملA Comparative Study of Intraocular Pressure Measurement Using Tonopen and Goldmann Applanation Tonometer
Background: Glaucoma is the world's leading cause of preventable irreversible blindness. The most important risk factor of glaucoma is increase in the intraocular pressure.Hence, timely screening by accurate IOP measurements is of utmost importance. In recent years, Tonopen has emerged as an alternative to Goldmann applanation tonometer which is the ‘gold standard’ for IOP measurement because o...
متن کاملComparability and Influence of Central Corneal Thickness (CCT) on Measurements of Intraocular Pressure (IOP) by Goldmann Applanation Tonometry (GAT) and Non Contact Tonometry (NCT) in Different IOP Ranges
Aim : To compare IOP measurements using GAT and NCT in different IOP ranges (<10, ≥10-25 mm Hg and > 25 mm Hg) and evaluate the effect of CCT on IOP measurements by these techniques. Materials and Methods: IOP was measured by NCT followed by GAT in 188 eyes of 100 glaucoma patients attending glaucoma clinic at Chaithanya Eye Hospital , Trivandrum by a single observer. Mean of three consecutive ...
متن کاملEffect of corneal thickness on intraocular pressure measurements with the pneumotonometer, Goldmann applanation tonometer, and Tono-Pen.
PURPOSE To compare intraocular pressure (IOP) measurements of the Ocular Blood Flow (OBF) pneumotonometer, Goldmann applanation tonometer, and Tono-Pen in eyes with normal corneas of various thicknesses. METHODS IOP was measured with an OBF pneumotonometer, Tono-Pen and Goldmann applanation tonometer in random order in 181 eyes with normal corneas. Central corneal thickness (CCT) was measured...
متن کاملComparison of intraocular pressure measurements with the portable PT100 noncontact tonometer and goldmann applanation tonometry
PURPOSE Noncontact tonometers are useful when regulations preclude use of contact tonometers by medical students and other nonophthalmologists. Our study compared the measurements by the portable, noncontact tonometer (PT100) with Goldmann applanation tonometry (GAT). METHODS This was a prospective study of 98 eyes from 98 patients. Intraocular pressure (IOP) was measured by GAT and the PT100...
