Contact Lens Dynamometry: The Influence of Age

Abstract

The relative slopes of the regression lines relating age to diastolic and systolic pressures are steeper in the ophthalmic than in the subclavian artery, indicating that the pressures in the ophthalmic artery increase faster with age than do the associated pressures in the subclavian artery, as measured by the standard sphygmomanometry. This phenomenon may be explained by progressive stiffening of the walls in the carotid and ophthalmic arteries. The effect of age should be taken into account whenever interpreting ophthalmodynamometric measurements for clinical diagnostic purposes.

Enhanced Pressure in the Central Retinal Vein Decreases the Perfusion Pressure in the Prelaminar Region of the Optic Nerve Head

“…The Poph can be measured by ODM, most conveniently by CLD. 17 These abbreviations and definitions described in this report may help to clarify new differentiations of PPs, which are made feasible by the measurement of the CRVP by CLD. An association has been shown between the glaucomatous optic nerve damage and the ODM force that is required to elicit a pulsation of the CRV.…”

Ocular perfusion pressure in glaucoma

“…Therefore, most of them are no longer available commercially. Still available are the suction cup method, and the contact lens dynamometer, which consists of a Goldmann type three mirror lens with an integrated pressure sensor (Stodtmeister et al 2010). As the measurements are subjective and need profound training of the examiner, the instruments have not found widespread use.…”

Specialized Diagnostic Investigations to Assess Ocular Status in Hypertensive Diseases of Pregnancy

“…Ophthalmodynamometry is recommended a routine technique for investigation in pregnancy. New modification in ophthalmodynamometry device consists of pressure sensor with mounting support of Goldman contact lens [23]. Ophthalmodynamometry has shown a lot of promise recently to visualize spontaneous pulsations of central retinal vein in daily ophthalmic practice and also as a non-invasive means to assess intracranial pressure [24,25].…”
