Ophthalmic diagnostic testing

At The Chelmsford Eye Clinic, Essex our goal is to achieve the best clinical outcomes for all our patients. Our approach combines the skills of our consultant-led eye health team with the latest diagnostic technology and the highest standards of patient care.
We also understand how important it is to take the time to explain diagnoses, treatment options, procedures and expected outcomes to ensure the whole experience at The Chelmsford Eye Clinic is as comfortable as possible.

 

Glaucoma tests

  •  Computerised Visual Field Assessment: this will map out the function of the retinal nerves at the back of the eye. The simple hi-tech assessment detects, plots and analyses less sensitive and blank areas of the patient’s field of vision.
  •  Optical Coherence Tomography (OCT): this provides exceptional detail of the structure of the optic nerve. The detailed statistical analysis makes it possible to detect glaucoma damage before vision is lost.
  •  Retinal Photography: this high resolution digital camera photographs the back of the eye recording even the smallest abnormality.
  •  Central corneal thickness: the thickness of the front surface of the eye is scanned and measured to provide a more accurate interpretation of the pressure inside the eye. For example, a thin cornea underestimates a pressure reading so this additional measure is important for accurate detection. Incidentally, a thin cornea is also a risk factor for glaucoma in itself.
  •  Consultation: the health of your retina, optic disc and structures of the eye are examined using a slit lamp and ophthalmoscope by our consultant surgeon. The pressure in the eye is measured using the gold standard applanation tonometer attached to the slit lamp. This is the only part of the testing which patients may find slightly uncomfortable but anaesthetic eye drops with yellow dye are used to allow the instrument to painlessly touch the front of the eye.

 

Retinal problems and macular disorder testing

  • Visual acuity: a computerised eye test to assess the patient’s sight.
  •  Optical Coherence Tomography test: the OCT uses the latest definition scanning technology to record magnified cross sectional images of the retina and macular. A colour photograph of the retina is also recorded. OCT detects problems early to allow medical practitioners to initiate treatment to preserve and save eyesight. OCT has revolutionised the early detection and treatment of retinal conditions such as Wet Age Related Macular Degeneration (Wet AMD) that damages precise and central vision.
  •  Consultation: the health of the retina, optic disc and structures of the patient’s eye are examined using a slit lamp and ophthalmoscope by our consultant surgeon.

 

Squints/lazy eye test

  •  A full eye examination, including measurement of visual acuity and refraction, is required to look for any treatable causes that need correcting such as a need for spectacles.
  •  An orthoptic assessment is also required for any squints that may be present so that visual acuity and coordination of the eyes can be assessed.
