  2. 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]

  3. 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 ...

  4. Glaucoma - Wikipedia

    en.wikipedia.org/wiki/Glaucoma

    For eye pressures, a value of 28 hPa (21 mmHg) above atmospheric pressure 1,010 hPa (760 mmHg) is often used, with higher pressures leading to a greater risk. [2] [26] However, some may have high eye pressure for years and never develop damage. [2] Conversely, optic nerve damage may occur with normal pressure, known as normal-tension glaucoma. [27]

  5. Intraocular pressure - Wikipedia

    en.wikipedia.org/wiki/Intraocular_pressure

    Intraocular pressure (IOP) is the fluid pressure inside the eye. Tonometry is the method eye care professionals use to determine this. IOP is an important aspect in the evaluation of patients at risk of glaucoma. [1] Most tonometers are calibrated to measure pressure in millimeters of mercury .

  6. Retinal haemorrhage - Wikipedia

    en.wikipedia.org/wiki/Retinal_haemorrhage

    Retinal hemorrhage (UK English: retinal haemorrhage) is a disorder of the eye in which bleeding occurs in the retina, the light sensitive tissue, located on the back wall of the eye. [1] There are photoreceptor cells in the retina called rods and cones , which transduce light energy into nerve signals that can be processed by the brain to form ...

    en.wikipedia.org/wiki/Hypertension

    Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. [11] High blood pressure usually does not cause symptoms itself. [1]

  9. Schwartz–Matsuo syndrome - Wikipedia

    en.wikipedia.org/wiki/Schwartz–Matsuo_syndrome

    Intra ocular pressure can be as high as 60–70 mm Hg and is responsive to aqueous suppressants. [3] Eye pain, blurred vision, headache, nausea, or vomiting may occur due to elevated intra ocular pressure. [1] Visual field defects, photopsia, floaters, blurring of vision etc. may occur due to retinal detachment. [1]
