  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. Humphrey visual field analyser - Wikipedia

    en.wikipedia.org/wiki/Humphrey_Visual_Field_Analyser

    Figure 1 - Humphrey field analyser. Humphrey field analyser (HFA) is a tool for measuring the human visual field that is commonly used by optometrists, orthoptists and ophthalmologists, particularly for detecting monocular visual field.

  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. Visual field test - Wikipedia

    en.wikipedia.org/wiki/Visual_field_test

    A visual field test is an eye examination that can detect dysfunction in central and peripheral vision which may be caused by various medical conditions such as glaucoma, stroke, pituitary disease, brain tumours or other neurological deficits.

  6. Ocular tonometry - Wikipedia

    en.wikipedia.org/wiki/Ocular_tonometry

    The ocular response analyser (ORA) is a non-contact (air puff) tonometer that does not require topical anaesthesia and provides additional information on the biomechanical properties of the cornea. It uses an air pulse to deform the cornea into a slight concavity.

  7. Glaucoma - Wikipedia

    en.wikipedia.org/wiki/Glaucoma

    The study found that Black adults were about twice as likely to be affected by glaucoma as White adults. Glaucoma prevalence was 1.62% among individuals aged 18 and older and 2.56% among those aged 40 and older, while vision-affecting glaucoma occurred in 0.57% and 0.91% of these age groups, respectively.

  8. Hypertensive retinopathy - Wikipedia

    en.wikipedia.org/wiki/Hypertensive_retinopathy

    Signs of damage to the retina caused by hypertension include: [citation needed]. Laser Doppler imaging of the papilla of a patient with hypertension. Arteriolar changes, such as generalized arteriolar narrowing, focal arteriolar narrowing, arteriovenous nicking, changes in the arteriolar wall (arteriosclerosis) and abnormalities at points where arterioles and venules cross.

  9. Brimonidine/timolol - Wikipedia

    en.wikipedia.org/wiki/Brimonidine/timolol

    A 12-week prospective, randomized, double-blinded study in 371 glaucoma and ocular hypertension patients with inadequate IOP control on monotherapy compared the efficacy and safety of 0.2% brimonidine tartrate/0.5% timolol fixed combination twice daily with the concomitant use of 0.2% brimonidine tartrate twice daily and timolol 0.5% twice ...
