摘要：
An intraocular pressure detecting device includes a pressure generation unit, a light source, an image sensing unit and a processing unit. The pressure generation unit applies pressure to a target surface of an eyeball along a first operation axis direction, such that a deformation is generated on the target surface. The light source emits light that irradiates the target surface along a second operation axis direction, so as to generate a speckle pattern on the target surface. The image sensing unit observes and records an image variation of the speckle pattern along a third operation axis direction. The processing unit is signally connected with the image sensing unit to receive an image of the speckle pattern. The processing unit identifies and analyzes a feature size of the image of the speckle pattern for obtaining an intraocular pressure value of the eyeball. An intraocular pressure detecting method is also described.
