DIGITAL RETINAL PHOTOGRAPHY
Here is a summary of the benefits of Digital
A scan to confirm a healthy eye or detect the
presence of disease.
An overview or map of the retina, giving your
Optometrist a more detailed view than they can achieve by other means.
The opportunity for you to view and discuss
the images of your eye with your Optometrist at the time of your examination.
We recommend that all our patients receive
this test. It is especially important for patients with a history of high blood
pressure, diabetes, retinal diseases, flashes of light, floaters, headaches and
those with a strong glasses prescription.
Optical Coherence Tomography (OCT) is a
non-invasive diagnostic instrument used for imaging the retina. It has
the ability to detect problems in the eye prior to any symptoms being present
in the patient. With an OCT, Optometrists are able to see a cross section or 3D
image of the retina and detect the early onset of a variety of eye conditions
and eye diseases such as macular degeneration, glaucoma and diabetic
retinopathy (the top three diseases known to cause blindness).
Some eye disorders cannot be visualised with
the naked eye. The normal viewing or photography that takes place
during a comprehensive eye examination does not show what’s happening
under the surface. To see what’s really going on, we can use Optical
Coherence Tomography. It allows us to image the underlying layers of the eye in
a non-invasive way. This is invaluable for picking up problems with the retina
and macula as well as diagnosing and monitoring the progress of progressive diseases
such as glaucoma. It is safe to use as often as you like without risk to the
eye’s delicate tissues.
The OCT allows for detection of other diseases
such as macular holes, hypertensive retinopathy and even optic nerve
damage. Using an OCT allows for early treatment in patients and
dramatically improves the success of these treatments, especially in diseases
such as wet macular degeneration – where the eye disease progresses rapidly.
The OCT has become the standard of care for
the assessment and treatment of most retinal diseases, Optometrists can
determine which retinal disease or eye condition exists in the eye, even before
the patient is aware of any problems.
Corneal topography is a process for mapping
the surface curvature of the cornea, similar to making a contour map of land.
The cornea is a clear membrane that covers the front of the eye (See Anatomy of
the Eye) and is responsible for about 70 percent of the eye’s focusing power.
To a large extent, the shape of the cornea determines
the visual ability of an otherwise healthy eye. A perfect eye has an evenly
rounded cornea, but if the cornea is too flat, too steep, or unevenly curved,
less than perfect vision results.
The purpose of corneal topography is to
produce a detailed description of the shape and power of the cornea. Using
computerized imaging technology, the 3-dimensional map produced by the corneal
topographer aids the Optometrist in the diagnosis, monitoring, and treatment of
various visual conditions.
Many eye and brain disorders can cause
peripheral vision loss and other visual field abnormalities. Visual field tests
are performed by eye care professionals to detect blind spots (scotomas) and
other visual field defects, which can be an early sign of these problems.
The size and shape of a scotoma offer
important clues about the presence and severity of diseases of the eye, optic
nerve and visual structures in the brain. For example, optic nerve damage
caused by glaucoma creates a very specific visual field defect.
Other conditions associated with blind spots
and other visual field defects include diseases of the retina, optic
neuropathy, brain tumors and stroke.
During a routine eye exam, your optometrist
may recommend visual field testing to assess the full horizontal and vertical
range and sensitivity of your vision. These “baseline” visual field
test results can then be used to assess potential changes in your visual field
in the future.
The Humphrey Field Analyzer is a diagnostic tool used to examine a patient’s visual field. The Humphrey Field Analyzer (HFA) is the recognized gold standard of care for early diagnosis and management of ocular diseases resulting in visual field loss.
invested in the Humphrey Field Analyzer …
the HFA has been shown to be extremely accurate.
Early Glaucoma Detection
this technology has been shown to provide earlier detection of vision loss due to glaucoma.
the HFA measures visual fields in as little as two minutes.
Range of Diagnostic tests available
The HFA offers ALL field screening strategies available including Esterman Binocular screening required for drivers licence assessments.
