  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]

    The skull bone behind Hermansen’s right eye was gone. In its place was a hole, allowing her brain to press against the eye, which explained the pulsating, said Dr. Netanel Ben-Shalom, a ...

  4. Visual snow syndrome - Wikipedia

    en.wikipedia.org/wiki/Visual_snow_syndrome

    The underlying mechanism is believed to involve excessive excitability of neurons in the right lingual gyrus and left anterior lobe of the cerebellum. Another hypothesis proposes that visual snow syndrome could be a type of thalamocortical dysrhythmia and may involve the thalamic reticular nucleus (TRN). A failure of inhibitory action from the ...

  6. Intraocular pressure - Wikipedia

    en.wikipedia.org/wiki/Intraocular_pressure

    Intraocular pressure varies throughout the night and day. The diurnal variation for normal eyes is between 3 and 6 mmHg and the variation may increase in glaucomatous eyes. During the night, intraocular pressure may not decrease [ 17 ] despite the slower production of aqueous humour. [ 18 ]

  7. Ocular tonometry - Wikipedia

    en.wikipedia.org/wiki/Ocular_tonometry

    When the area of a circle with diameter 3.06 mm (0.120 in) has been flattened, the opposing forces of corneal rigidity and the tear film are roughly approximate and cancel each other out allowing the pressure in the eye to be determined from the force applied.

  8. Blurred vision - Wikipedia

    en.wikipedia.org/wiki/Blurred_vision

    Cataracts: Cloudiness over the eye's lens, cause blurring of vision, halos around lights, and sensitivity to glare. [5] It is also the main cause of blindness worldwide. [2] Glaucoma: Increased intraocular pressure (pressure in the eye) cause progressive optic neuropathy that leads to optic nerve damage, visual field defects and blindness. [6]
