  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. Hypertensive retinopathy - Wikipedia

    en.wikipedia.org/wiki/Hypertensive_retinopathy

    Strongly modulated blood flow pulse in central and branch arteries can result from hypertension. Microangiography by laser Doppler imaging [3] may reveal altered hemodynamics non-invasively. Mild signs of hypertensive retinopathy can be seen quite frequently in normal people (3–14% of adult individuals aged ≥40 years), even without ...

  4. Anterior ischemic optic neuropathy - Wikipedia

    en.wikipedia.org/wiki/Anterior_ischemic_optic...

    This optic nerve must penetrate through the wall of the eye, and the hole to accommodate this is usually 20-30% larger than the nerve diameter. In some patients the optic nerve is nearly as large as the opening in the back of the eye, and the optic disc appears "crowded" when seen by ophthalmoscopy. A crowded disc is also referred to as a "disc ...

    In 2018, it was reported that more than 7,000 ophthalmology patients at University Hospital Southampton NHS Foundation Trust, 4,500 with glaucoma and 2,500 with diabetes-related eye problems, had not been given follow-up appointments. The trust said there had been a 5% rise in patients every year and demand had outstripped capacity in most NHS ...

  6. Ischemic optic neuropathy - Wikipedia

    en.wikipedia.org/wiki/Ischemic_optic_neuropathy

    Ischemic optic neuropathy (ION) is the loss of structure and function of a portion of the optic nerve due to obstruction of blood flow to the nerve (i.e. ischemia).Ischemic forms of optic neuropathy are typically classified as either anterior ischemic optic neuropathy or posterior ischemic optic neuropathy according to the part of the optic nerve that is affected.

  7. 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.

  8. Ocular ischemic syndrome - Wikipedia

    en.wikipedia.org/wiki/Ocular_ischemic_syndrome

    Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...

  9. Latanoprost - Wikipedia

    en.wikipedia.org/wiki/Latanoprost

    Latanoprost, sold under the brand name Xalatan among others, is a medication used to treat increased pressure inside the eye (intraocular pressure). [5] This includes ocular hypertension and open-angle glaucoma. [5] Latanaprost is applied as eye drops to the eyes. [5] Onset of effects is usually within four hours, and they last for up to a day.
