  2. Intraocular pressure - Wikipedia

    en.wikipedia.org/wiki/Intraocular_pressure

    Differences in pressure between the two eyes are often clinically significant, and potentially associated with certain types of glaucoma, as well as iritis or retinal detachment. Intraocular pressure may become elevated due to anatomical problems, inflammation of the eye, genetic factors, or as a side-effect from medication. Intraocular ...

  3. Ocular hypertension - Wikipedia

    en.wikipedia.org/wiki/Ocular_hypertension

    Ocular hypertension is the presence of elevated fluid pressure inside the eye (intraocular pressure), usually with no optic nerve damage or visual field loss. [1] [2]For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [3]

  4. Glaucoma - Wikipedia

    en.wikipedia.org/wiki/Glaucoma

    A major risk factor for glaucoma is increased pressure within the eye, known as intraocular pressure (IOP). [1] It is associated with old age, a family history of glaucoma, and certain medical conditions or the use of some medications. [6] The word glaucoma comes from the Ancient Greek word γλαυκός (glaukós), meaning 'gleaming, blue ...

  5. Visual impairment - Wikipedia

    en.wikipedia.org/wiki/Visual_impairment

    Glaucoma is an eye disease often characterized by increased pressure within the eye or intraocular pressure (IOP). [61] Glaucoma causes visual field loss as well as severs the optic nerve. [62] Early diagnosis and treatment of glaucoma in patients is imperative because glaucoma is triggered by non-specific levels of IOP. [62]

  6. Pseudoexfoliation syndrome - Wikipedia

    en.wikipedia.org/wiki/Pseudoexfoliation_syndrome

    The blockage leads to greater-than-normal elevated intraocular pressure [2] which, in turn, can damage the optic nerve. [7] The eye produces a clear fluid called the aqueous humor which subsequently drains such that there is a constant level of safe pressure within the eye, but glaucoma can result if this normal outflow of fluid is blocked.

  7. Ocular tonometry - Wikipedia

    en.wikipedia.org/wiki/Ocular_tonometry

    Tonometry is the procedure that eye care professionals perform to determine the intraocular pressure (IOP), the fluid pressure inside the eye.It is an important test in the evaluation of patients at risk from glaucoma. [1]

  8. Normal tension glaucoma - Wikipedia

    en.wikipedia.org/wiki/Normal_tension_glaucoma

    Over many years, glaucoma has been defined by an intraocular pressure of more than 20 mm Hg. Incompatible with this (now obsolete) definition of glaucoma was the ever larger number of cases that have been reported in medical literature in the 1980s and 1990s who had the typical signs of glaucomatous damage, like optic nerve head excavation and thinning of the retinal nerve fiber layer, while ...

  9. Anterior chamber of eyeball - Wikipedia

    en.wikipedia.org/wiki/Anterior_chamber_of_eyeball

    The anterior chamber is the aqueous humor-filled space inside the eye between the iris and the cornea's innermost surface, the endothelium. [1] Hyphema, anterior uveitis and glaucoma are three main pathologies in this area. In hyphema, blood fills the anterior chamber as a result of a hemorrhage, most commonly after a blunt eye injury.
