  2. Ocular hypertension - Wikipedia

    en.wikipedia.org/wiki/Ocular_hypertension

    For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [3] It is estimated that approximately 2-3% of people aged 52-89 years old have ocular hypertension of 25 mmHg and higher, and 3.5% of people 49 years and older have ocular hypertension of 21 mmHg and higher. [4]

  3. Eye disease - Wikipedia

    en.wikipedia.org/wiki/Eye_disease

    This is a partial list of human eye diseases and disorders. The World Health Organization (WHO) publishes a classification of known diseases and injuries, the International Statistical Classification of Diseases and Related Health Problems, or ICD-10. This list uses that classification.

  4. 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.

  5. List of systemic diseases with ocular manifestations - Wikipedia

    en.wikipedia.org/wiki/List_of_systemic_diseases...

    There are many diseases known to cause ocular or visual changes. Diabetes , for example, is the leading cause of new cases of blindness in those aged 20–74, with ocular manifestations such as diabetic retinopathy and macular edema affecting up to 80% of those who have had the disease for 15 years or more.

  6. Glaucoma - Wikipedia

    en.wikipedia.org/wiki/Glaucoma

    Ocular hypertension (increased pressure within the eye) is an important risk factor for glaucoma, but only about 10-70% of people - depending on ethnic group - with primary open-angle glaucoma actually have elevated ocular pressure. [24] Ocular hypertension—an intraocular pressure above the traditional threshold of 21 mmHg (28 hPa) or even ...

  7. 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 ...

  8. Posner–Schlossman syndrome - Wikipedia

    en.wikipedia.org/wiki/Posner–Schlossman_syndrome

    Ocular hypertension (IOP 30 - 70 mmHg) with open angle of anterior chamber and unilateral mild granulomatous anterior uveitis are hallmark signs of Posner–Schlossman syndrome. [2] On slit-lamp examination, conjunctival injections, epithelial corneal edema, [ 3 ] small to medium-sized fine keratitic precipitates, aqueous cells and flare may ...

  9. Non-arteritic anterior ischemic optic neuropathy - Wikipedia

    en.wikipedia.org/wiki/Non-arteritic_anterior...

    Fluorescein angiographic studies [9] [10] have demonstrated that during the acute phase of NAION, there is a delay in blood flow to the optic disc, suggesting a potential impairment in the arteries directly supplying it. Other research indicates that a drop in blood pressure within specific critical areas of the optic disc's blood supply ...
