    摘要: An excitation force (internal or external) and phase-sensitive optical coherence elastography (OCE) system, used in conjunction with a data analyzing algorithm, is capable of measuring and quantifying biomechanical parameters of tissues in situ and in vivo. The method was approbated and demonstrated on an example of the system that combines a pulsed ultrasound system capable of producing an acoustic radiation force on the crystalline lens surface and a phase-sensitive optical coherence tomography (OCT) system for measuring the lens displacement caused by the acoustic radiation force. The method allows noninvasive and nondestructive quantification of tissue mechanical properties. The noninvasive measurement method also utilizes phase-stabilized swept source optical coherence elastography (PhS-SSOCE) to distinguish between tissue stiffness, such as that attributable to disease, and effects on measured stiffness that result from external factors, such as pressure applied to the tissue. Preferably, the method is used to detect tissue stiffness and to evaluate the presence of its stiffness even if it is affected by other factors such as intraocular pressure (IOP) in the case of cornea, sclera, or the lens. This noninvasive method can evaluate the biomechanical properties of the tissues in vivo for detecting the onset and progression of degenerative or other diseases (such as keratoconus).

    摘要: An excessive amount of pressurized air is inhibited from being blown to an eye of a patient during measurement of a corneal shape deformation amount. In a non-contact tonometer having a piston, a driving unit to drive the piston, a fluid ejection unit to blow air pressurized by driving the piston toward a cornea of an eye to be inspected, and an intraocular pressure measuring unit to detect a deformed state of the cornea and measure an intraocular pressure, there are provided a piston displacement restricting unit that restricts a displacement amount when the piston pressurizes the air, and a changing unit to change the displacement amount to be restricted by the piston displacement restricting unit.

    摘要: In an ophthalmic instrument that directs a fluid pulse at a cornea to cause reversible deformation of the cornea and monitors the corneal deformation to generate a deformation signal, the shape of the deformation signal is analyzed with respect to deformation signal data from a statistical population of eyes to calculate a deformation signal score indicating a degree of probability that the deformation signal corresponds in shape to a normal deformation signal for normal eyes in the population. In calculating the deformation signal score, significant geometrical signal parameters are calculated and combined. The deformation signal score may be used as a basis to keep or discard intraocular pressure measurements in a non-contact tonometer, and/or as a basis to conduct further diagnostic screening.

    摘要: Systems and methods of sensing intraocular pressure are described. An example miniaturized intraocular pressure (IOP) monitoring system is provided using a nanophotonics-based implantable IOP sensor with remote optical readout that can be adapted for both patient and research use. A handheld detector optically excites the pressure-sensitive nanophotonic structure of the IOP-sensing implant placed in the anterior chamber and detects the reflected light, whose optical signature changes as a function of IOP. Optical detection eliminates the need for large, complex LC structures and simplifies sensor design. The use of nanophotonic components improves the sensor's resolution and sensitivity, increases optical readout distance, and reduces its size by a factor of 10-30 over previous implants. Its small size and convenient optical readout allows frequent and accurate self-tracking of IOP by patients in home settings.
