Perkins hand-held applanation tonometer. A clinical evaluation.
MANY ophthalmologists measure intra-ocular pressure with the Goldmann tonometer. It is neither portable nor capable of being used with the patient supine, which is disadvantageous in glaucoma screening programmes when it is often necessary to examine sick patients in their homes. An applanation tonometer, which is portable and can be used with the patient supine, sitting, or even standing, has ...
متن کاملUse of the Perkins hand-held applanation tonometer in retinal detachment surgery.
The applanation method is generally accepted as being the most accurate for measuring intraocular pressure. Perkins (i965) described a hand-held portable applanation tonometer. Whitty (I969) reported his results using this tonometer: he found that readings with the hand applanator were slightly (I-I-5 mm.Hg) lower than those taken with the Haag-Streit tonometer, and he felt that this may have b...
متن کاملComparative study of measurement of IOP with Goldmann’s applanation tonometer and Non contact tonometer
Aim : The aim of this study is to validate the efficacy of NCT by comparing its measurements with that of Goldmann’s applanation tonometry and to know if it can be used as a screening tool for glaucoma. Materials and methods : In 400 eyes of 200 adults selected for cataract surgery, IOP was measured first with NCT and 15min later with GAT and the results were compared. Results : The range of IO...
متن کاملComparison of IOPen rebound tonometer with Goldmann applanation tonometer at different IOP levels.
AIM To compare the accuracy of IOPen rebound tonometer with Goldmann applanation tonometer (GAT) in individuals with low, normal and high intraocular pressure (IOP) and to evaluate the effect of central corneal thickness (CCT) on IOP measurements. METHODS This cross-sectional study consisted of 159 participants. IOP of one eye of each subject was measured consecutively with IOPen and GAT. The...
متن کاملA Study of Intraocular Pressure with I Care Tonometer & Applanation Tonometer
Purpose: To compare the Intra Ocular Pressure (IOP) measurements obtained by Applanation Tonometer (AT) & Rebound Tonometer (RT). Methods: The Central Corneal Thickness (CCT) corrected IOP of 100 eyes were measured using first with RT (I Care) followed by AT (GAT). Results were compared statistically using Bland –Altman plot & Deming’s regression analysis. Results: Scatter plot analysis showed ...
