Abstract: Accurate intraocular pressure (IOP) measurement is crucial in eye diseases such as glaucoma. Direct measurement of intraocular pressure can avoid the influence of the cornea on the measurement accuracy and clarify the pressure in the posterior eye segment as well as the distribution of the pressure inside the eyeball. Safe and minimally invasive devices are currently available for the pressure measurement of the anterior chamber and the vitreous cavity. Pupillary block, aphakia and the changes in the composition of the vitreous cavity can affect the pressure distribution in the anterior chamber and the vitreous cavity. Performing intraocular pressure measurements can provide more information and new ideas for diagnosis and treatment of malignant glaucoma and other certain diseases.
