Can glaucoma affect your balance?

Conclusions.: Glaucoma patients display differences in their visual and somatosensory contributions to quiet standing balance compared with control subjects, associated with the degree of binocular visual field loss. This suggests that balance control may be compromised in this patient group.

Does glaucoma affect mobility?

Glaucoma is associated with a modest decrease in mobility performance. Walking speed decreases with severity of the disease as estimated by threshold perimetry.

What does fixation loss mean?

Fixation losses occur when the patient reports seeing a stimulus that is presented in the predicted area of the physiologic blind spot. False positives occur when a patient presses the button when no stimulus is presented.

How would you describe visual field defects?

A visual field defect is a loss of part of the usual field of vision, so it does not include severe visual impairment of either one eye or both. The lesion may be anywhere along the optic pathway; retina to occipital cortex.

When does an altitudinal field defect cross the Merid-Ian?

shows loss of all or part of the superior half or the inferior half of the visual field of one or both eyes, and which respects the horizontal meridian. In case the field defect crosses the horizantal merid- ian than the field defect could no longer be called an altitudinal field defect.

What does inferior hemianopia mean in medical terms?

Inferior hemianopia: Inferior hemianopia is when loss of vision occurs in the lower visual field of either the left, right, or both eyes.

Who are patients with superior altitudinal field defect?

Some patients with bilateral optic neuropathies particularly those who develop bilateral simultaneous or non-simultaneous ante- rior ischaemic optic neuropathy(AION ) develop a superior altitudinal field defect in one eye and an inferior altitudinal field defect in the other.

How does the retinal hemifield slide effect the eye?

Patients with the retinal hemifield slide phenomenon may complain about a range of ocular manifestations including “doubling” strip of central vision, “missing” strip of central vision, or visual hemifields “sliding” respective to one another. In bitemporal hemianopia, each eye has a loss of its temporal field of vision.
