OBJECTIVE To evaluate the results of scanning laser tomography and scanning laser polarimetry (SLP) and the correlations with visual field damage (VFD) in eyes with nonarteritic ischemic optic neuropathy (n-AION) compared with eyes with open-angle glaucoma (OAG). DESIGN Cross-sectional study. PARTICIPANTS Thirty-three eyes of 33 patients with n-AION and(More)
Goldmann applanation tonometry is commonly used for measuring intraocular pressure (IOP) to diagnose glaucoma. However, the measured IOP by conventional applanation tonometry is valid only under the assumption that all subjects have the same structural eye stiffness. This paper challenges in vivo measurement of eye stiffness with a noninvasive approach and(More)
This paper presents novel details on the dynamic behavior of human eyes (see Fig.1). A high speed camera is used to capture the movement of the eye surface, which is excited by an air jet. For one group of subjects the dynamic respose of the eyes ends shortly after the air jet stops. For another group of subjects a distinct offset in the displacement(More)
Non-contact tonometers are widely used to measure the internal eye pressure, i.e. the IntraOcular Pressure (IOP), which is an important parameter for the diagnosis and treatment of glaucoma. During the measurement, the eye is deformed by a short air pulse. Commonly the pressure dependent deformation is estimated from the time when the eye becomes flat,(More)
For the diagnosis and treatment of glaucoma, a reliable and non-invasive measurement method of the internal eye pressure, i.e. the intraocular pressure (IOP), is desired. The IOP resists a deformation of the eye and thus non-contact tonometers, which deform the eye by a short air pulse, are suitable to estimate the IOP. By monitoring the reflection of an(More)
The eye pressure is an important index for judging whether an eye suffers from glaucoma or not. Conventional eye pressure measurements provide us with meaningful data only under the assumption that all the subjects have the same eye stiffness. Our former work, however, says that the assumption is not valid. This work is an extended version. By combining(More)
The internal eye pressure is an important index for judging whether an eye suffers from glaucoma or not. The conventional eye pressure measurement is valid only under the condition that all subjects have the same structural eye stiffness. This paper challenges the practice of measuring the stiffness of a human eye by pressing the cornea with a contact(More)
The contact tonometer is commonly used for measuring the internal eye pressure to diagnose glaucoma. However, the conventional eye pressure measurement is valid only under the assumption that all subjects have the same structural eye stiffness. This paper challenges to measure the contact area between the probe and the cornea in addition to the corneal(More)
