Specialist Equipment

At Optitech, we strive to keep to the front end of technology. Over the past 20 years, there has been a rapid advancement in technology for use in every aspect of eye care. In particular, the development of retinal digital cameras and more advanced imaging devices has vastly improved our detection of:

  • Diabetic eye disease
  • Early glaucoma
  • Age-related macular degeneration
  • Moles in the retina (or naevi)

We offer this more enhanced eye examination to both our NHS and private patients at a small additional cost. This imaging is very safe and quick, involving only a few flashes of light. We usually incorporate it with your eye examination, especially if pre-booked.

Retinal Imaging

The introduction of digital imaging made a significant impact on the delivery of eye health in optometry. This instrument allows the capture of images of the retina at the back of your eye. These pictures can be viewed instantly on the computer screen, and manipulated using a magnification tool to provide a more in-depth assessment of subtle features.

This technique makes the examination more comfortable for you, as we no longer need to peer into your eyes at close proximity for such a lengthy period of time.

The special filters used by the retinal camera afford the advantage of better detection of 'moles' in the eye (technically called 'naevi'!) that can be more easily missed using traditional examination techniques. Retinal imaging also enables us to detect better early signs of small haemorrhages and blockages in your retinal capillaries that can indicate high blood pressure, high cholesterol or diabetes. It is now the mainline method of screening and monitoring diabetic eye disease.

Topcon 3D Ocular Coherence Tomography (OCT)

This latest technology has revolutionised the examination of the most important features of the retina, namely the optic nerve (structure that carries information back to the brain), and macula (central part of the retina).

Scans captured using the OCT provide invaluable information for both the early detection, and diagnosis of various eye conditions that may have otherwise been missed until a later stage in the disease process. By investigating deeper layers of the retina in a 3-dimensional image, the device looks beneath the surface, much like an ultrasound scan. Images can be acquired within a few seconds, in a simple and comfortable manner, with the patient experiencing light flashes during the measurement.

Our optometrists have undertaken vigorous training to analyse scans precisely, working alongside local ophthalmologists to inform decision-making and referrals for further investigation. OCT scans can be carried out for patients of all ages, but we recommend in particular, the following groups:

Individuals aged over 40 years, as these persons are more at risk of conditions such as glaucoma and macular degeneration
Those with a family history of age-related macular degeneration, glaucoma, or diabetes
Where results of previous tests in the eye examination warrant more frequent monitoring of the retina (e.g. a mole at the back of the eye)
As a baseline measurement for any age group, so that there is a reference for us to compare against if any future symptoms or conditions arise
The prognosis for conditions such as glaucoma, diabetic macular oedema and macular degeneration is better when detected and treated at an early stage to prevent further loss of vision.

Humphreys Field analyser

This is a tool for measuring the human visual field, it is used by optometrists, orthoptists and ophthalmologists, particularly for detecting monocular visual field.

The results of the Analyser identify the type of vision defect. Therefore, it provides information regarding the location of any disease processes or lesion(s) throughout the visual pathway. This guides and contributes to the diagnosis of the condition affecting the patient's vision. These results are stored and used for monitoring the progression of vision loss and the patient's condition.

This equipment is used in early detection of Glaucoma and other optic nerve related conditions. It is the hospital gold standard visual field equipment for detecting and monitoring changes in the optic nerve.

Goldmann Contact Tonometer

This provides a more accurate eye pressure measurement relative to the standard 'puffer' or the non-contact tonometer. It is the main choice of equipment preferred by hospital eye specialists.

Tonometry is generally performed upon an anesthetized ocular surface.The tonometer device lightly touches the surface of the eye, ever so slightly indenting the cornea. The resistance to indentation is measured by a precisely calibrated pressure sensing device, the tonometer.

Corneal Topographer

This non-invasive medical imaging equipment maps the surface curvature of the cornea, the outer structure of the eye. Since the cornea is normally responsible for some 70% of the eye's refractive power, its topography is of critical importance in determining the quality of vision and corneal health.
