Some of the diagnostic tests the Save Sight Institute clinic specialises in:

Digital Retinal Angiography
allows us to view angiograms in real time. It also allows electronic storage
of the images on CD for portability in a format useful for teaching purposes.
The digital angiogram can have a number of digital filters applied which
obtain reasonable results even in patients with lens opacities. The Institute
also records colour slide photographs of the retina, both for the patient's
record and for teaching purposes.

Digital Fundus & Anterior Segment Photography
allows us to document the appearance of the anterior and posterior structures
of the eye. This helps monitor recovery from or progression of various
diseases over time as well as assisting in explaining to patients where
and how their eye problem is occurring.

Heidelberg Retinal Angiography
allows us to perform digital Fluorescein and Indocyanine Green angiography
with three-dimensional resolution, improving the diagnosis of retinal and
choroidal pathologies such as diabetic retinopathy and macular degeneration.
Infrared and Autofluorescent imaging on this machine provide new ways of
identifying various manifestations of retinal disease.

Visual Evoked Potentials and Multifocal Visual Evoked Potential
record the electrical responses from the eye when presented with a visual
stimulus such as a flashing light or chequered screen. They assist in the
diagnosis and management of disorders such as optic neuritis, optic tumours
and various retinal disorders.

The AccuMap
is an objective recording of the visual field relying on the responses
from the eye and brain, thus making it a more reliable way of mapping visual
fields. This is extremely useful in the diagnosis and management of various
retinal disorders such as glaucoma and optic neuritis.

Full Field Electroretinography
measures the electrical response from the various cell types in the retina
using electrodes placed on the cornea of the eye and the skin around the
eye. It is used to diagnose various retinal disorders such as retinitis
pigmentosa, rod-cone dystrophies and retinoschisis.

Multifocal Electroretinography
records separate responses from localised areas of the retina. It is very
useful in the diagnosis of retinal diseases, particularly macular diseases
such as macular telangectasia.

is used to measure the resting potential of the retina and is used to assess
the function of the retinal pigment epithelium. It is used for the diagnosis
of diseases such as retinitis pigmentosa and congenital stationary night

Optical Coherence Tomography (OCT)
testing is used for the diagnosis and management of retinal diseases such
as macular degeneration, macular edema, macular holes, retinal tumours,
vitreous tractions and detachments, retinal dystrophies as well as glaucoma.

IOL Master
measures the axial length of the eye necessary for calculation of intraocular
lenses in cataract surgery.

B Scans
are used to monitor various retinal disorders such as retinal tumours and
retinal detachments.

Ultrasound Biomicroscopy (UBM)
is a new techniques used to obtain images of the anterior segment of the
eye at microscopic resolution. It is used in the assessment and diagnosis
of glaucoma, iris cysts and tumours, ocular traumas and intraocular lens

is used to analyses the thickness of the cornea which is extremely important
for monitoring various corneal diseases and glaucoma.

The Pentacam
images the anterior segment of the eye, providing three dimensional images
of the anterior chamber of the eye, measurement of the corneal thickness
and corneal topographic measurements of the front and back surfaces of
the cornea.

Confocal Microscopy
is a specialised diagnostic test of the cornea only available at the Save
Sight Institute Clinic. It is used to monitor the number, density and quality
of endothelial cells that line the back of the cornea.

Optos Widefield Imaging & Angiography
is a digital camera capable of capturing colour, red-free, autofluorescence
and angiography images from the far periphery of the retina with a 200
degree view of the retina. It is designed to aid in the diagnosis and
monitoring of diseases or disorders of the retina. It is also equipped with
a ResMax option for greater resolution and smaller field images. It is a
non-contact imaging system and pupil dilation is not necessary in most
cases, making it a user-friendly and patient-friendly camera.

Heidelberg Spectralis SD-OCT is an OCT with high resolution and
high definition imaging of the retinal layers allowing greater precision in
the diagnosis and therefore management of diseases of the retina and
optic nerve. It also incorporates the Enhanced Depth Imaging (EDI)
modality to improve the imaging of deeper retinal structures for greater
understanding of disease processes and better management outcomes.
