  2. Ocular hypotony - Wikipedia

    en.wikipedia.org/wiki/Ocular_hypotony

    Ocular hypotony is divided into statistical and clinical types. If intraocular pressure is low (less than 6.5 mm Hg) it is called statistical hypotony, and if the reduced IOP causes a decrease in vision, it is called clinical. [4]

  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. Intraocular pressure - Wikipedia

    en.wikipedia.org/wiki/Intraocular_pressure

    Ocular hypertension (OHT) is defined by intraocular pressure being higher than normal, in the absence of optic nerve damage or visual field loss. [ 13 ] [ 14 ] Ocular hypotension, hypotony, or ocular hypotony , is typically defined as intraocular pressure equal to or less than 5 mmHg.

  5. Glaucoma - Wikipedia

    A study with 1636 persons aged 40-80 who had an intraocular pressure above 24 mmHg in at least one eye but no indications of eye damages showed that after five years 9.5% of the untreated participants and 4.4% of the treated participants had developed glaucomatous symptoms, meaning that only about one in ten untreated people with elevated ...

  7. Flammer syndrome - Wikipedia

    en.wikipedia.org/wiki/Flammer_syndrome

    Best known is the higher risk of normal tension glaucoma, a disease with an impaired regulation of blood flow in a large number of patients. [9] If glaucomatous damage occurs despite normal eye pressure or if glaucomatous damage is progressive despite normalized intraocular pressure, frequently Flammer syndrome is the cause.

  8. 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]

  9. 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 ...
