These are the right and left optic nerves of a patient with intraocular pressures of 25mmHg in each eye. Average pressure in a person's eye is 15mmHg. This patient has slightly thicker corneas than average, indicating that true intraocular pressure is a little bit lower than clinically measured intraocular pressure. The deeper and width of the cupping of the optic nerve, which corresponds a little beyond the whitened center in the photos below, the higher the risk or suspicion of glaucoma. This patient requires a visual field test and possibly some other tests to determine if the optic nerve is having any damage from the higher intraocular pressure. Those tests should be performed within 3 months for this patient.
