Eye care equipment

The “puff-of air” test

The name for this is non-contact tonometry (NCT). This is where a trained person uses a machine to blow air on to the eye to determine the intraocular pressure (IOP).  This test can help detect signs of glaucoma as well as other conditions.

Slit lamp

This piece of equipment is used to shine light to the front and back of the eye. The practitioner then uses a binocular microscope to examine the structures of the eye in more detail.

Visual fields machine

This is used to assess a patients’ peripheral vision. It helps detect blind spot in the vision which the patient may not be aware of. This test can help detect conditions such as glaucoma and also signs of possible damage to the brain.

Digital retinal photography

This machine allows the structures of the retina to be captured as a digital image. This allows the optometrist to detect signs of damage. It is useful for records as it allows images to be compared over a number of years which can help detect signs of deterioration. It is often used as a screening tool for diabetic patients.

Optical Coherence Tomography (OCT)

This is a fairly new piece of equipment which a lot of opticians now have. This allows the optometrist to view the health of the eye in greater detail. The OCT scan allows you to see structures beneath the surface of the eye. It can help detect conditions such as macular degeneration and glaucoma earlier. The OCT scan is often a chargeable service as it is not included in the standard eye tests, however the benefits make it worthwhile having done.
