Intraocular pressure (IOP) is the fluid pressure inside the eye which is responsible for maintaining the shape of the globe.Intraocular pressure (IOP) is an eye parameter of fundamental importance for the diagnosis of several eye conditions, including glaucoma, ocular hypertension, uveitis and trauma.The aim of this study is to evaluate the difference between IOP measurements taken by a Goldmann Applanation Tonometer and those taken by an Air-Puff Tonometer and to observe the reliability of Air Puff to be a screening tool.In this cross sectional observational comparative study using random sample. The study population comprised 020 eyes from 100 participants males and females (including: relatives of patients, medical students, nurses and patients complaining from errors of refraction) attending the ophthalmic outpatient clinic In Benha University Hospital with age ranged between 18:80 years old. An informed consents were taken from all participants.All patients in this study underwent Full history and full ophthalmic examination and assessment of visual acuity: Uncorrected visual acuity (U.C.V.A.), best corrected visual acuity (B.C.V.A.), Refraction using NIDEK Auto-Refractometer-Keratometer, anterior segment examination by slit-lamp biomicroscopy, Intraocular pressure (IOP) measurement using Goldman Applanation Tonometer (Haag – Streit At 900˚ Swiss Made) and air- puff Tonometer ( Topcon Japan CT-80) , fundus examination (including posterior vitreous, disc and macular examination)
