Glaucoma Investigation

The visual field test measures how far in the periphery you can see. Glaucoma reduces your peripheral or side vision and its advanced stage, glaucoma will reduce your side vision to the point where it would be like looking through a ‘loo’ roll. Often patients do not notice any difference until it is too late.

Visual field test can often detect other neurological conditions such as brain tumours. It is also important that patients with sudden onset headaches or even visual migraines to have a visual field.

Edgbaston Eye Clinic boasts one of the most advanced diagnostic Visual Field Analyser

Eye Pressure is one of the most important risk factors for glaucoma. The Goldmann Applanation tonometry is the accepted gold standard for accurate and repeatable eye pressure measurement

The thickness of the cornea influences the pressure measurement. The cornea is often term the ‘window’ to the eye. Measuring the thickness of the cornea is very important factor in the investigation of glaucoma. Edgbaston Eye Clinic is equipped with one of the most advanced ophthalmic diagnostic equipment for accurate measurement of the central corneal thickness.

At Edgbaston Eye Clinic we are very lucky to be able to scan and visualise the drainage system of the eye and then make an assessment of the anatomical structures of the drainage system. This enables us to assess functionality of the drainage system.

We are also very lucky to be able to be able to video the drainage angle functioning. Gonioscopy involves gently putting a lens on the eye after numbing the cornea. The lens is cushion with some tear gel and there is not discomfort to patients.

The retinal nerve fibre layer inside the eye is very susceptible to damage as a result of glaucoma. With conventional tests, it will require approximately 30% of damage to this layer of nerves before it is identified however a scan of the this nerve layer fibre can detect damage at the earliest stage.

Treatment for glaucoma is more effective when it is detected very early. The RNFL scan is a very important test for early detection of any damage to the RNFL. Significant damage to the nerve fibre layer is irreversible and is sight threatening.

Edgbaston Eye Clinic is the only private provider equipped with the most advanced 3D or Stereoscopic ‘Eye Camera’.

The KOWA technology enables use to view the optic nerve in real life. Clinically, this is very important as we can analyse ‘inside’ the optic nerve to either rule out or confirm any damage as a result of glaucoma.

The 3D viewing experience is achieved by wearing 3D glasses. Both clinicians and patients can experience the 3D viewing.
