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 کاملEvaluation of the Perkins handheld applanation tonometer in horses and cattle
The objective of this study was to evaluate and validate the accuracy of the Perkins handheld applanation tonometer for measuring intraocular pressure (IOP) in horses and cattle. Both eyes of 10 adult horses and cattle were evaluated in a postmortem study. The eyes from 10 clinically normal adult horses and cattle were also examined after bilateral auriculopalpebral nerve block and topical anes...
متن کاملDiagnostic accuracy of the iCare rebound tonometer compared to the Perkins applanation tonometer in assessing intraocular pressure in rural patients.
BACKGROUND Vision health is recognized as a critical unmet need in North America. The ocular morbidity associated with glaucoma results from increased intraocular pressure (IOP) and early detection is crucial for the management of glaucoma. Our objective was to find a diagnostically accurate screening tool for intraocular hypertension that can be used in rural communities. We sought to validate...
متن کاملComparative evaluation of intraocular pressure with an air-puff tonometer versus a Goldmann applanation tonometer
PURPOSE Tonometry, or measurement of intraocular pressure (IOP), is one of the most important examination procedures in ophthalmic clinics, and IOP is an important parameter in the diagnosis of glaucoma. Because there are numerous types of tonometer available, it is important to evaluate the differences in readings between different tonometers. Goldmann applanation tonometers (GATs) and noncont...
