Valley Eye Specialists is equipped with a full range of diagnostic imaging equipment to provide a comprehensive ophthalmic assessment for all our adult and paediatric patients. Use of these diagnostic tests provides our doctors with gold standard and vital information that assists in determining an appropriate individual management plan.
Retinal imaging using this camera allows precise documentation of many eye conditions, as well as allowing in depth analysis of conditions that affect the macula, optic nerve, retina, and retinal blood supply. A single image can capture up to 200 degrees of the retina compared to the conventional 30-40 degrees, and in addition this camera can capture other specialised images such as fundus autofluorescence and fundus fluorescein angiography.
This machine tests and documents peripheral vision, which is essential for general navigation including safe mobility and driving. Peripheral vision can deteriorate silently in some conditions; therefore, it is often an important diagnostic test and can also be used to monitor effects of treatment for conditions such as glaucoma. Peripheral vision can also be affected in diabetes, stroke, and general optic nerve and retinal conditions.
This type of photography is commonly used to document the external appearance of the eye. It is an important tool for recording and monitoring ocular surface and eyelid lesions, as well as corneal ulcers and infections. This camera can also be used to photograph the iris and the lens of the eye, again for diagnostic and monitoring purposes.
Are you having cataract surgery? Our IOL master allows accurate measurement of all the dimensions of the eye that allow your ophthalmologist to determine the power and type of Intraocular lens that will be suitable for you to have implanted during cataract surgery. This machine is also routinely used to monitor the axial length of the eye in conditions such as myopia.
OCT stands for Optical Coherence Tomography which uses light waves to provide cross sectional images of the retina and optic nerve. These images have revolutionised diagnosis and management of macular diseases as well as conditions that affect the optic nerve such as glaucoma. Modern ophthalmology relies on this technology to provide information that is unable to be deduced through clinical examination of the eye alone.
B-scan ultrasonography is another way of obtaining information about the internal structures of the eye, and also in viewing the tissues behind the eye. It provides a cross-sectional image of lesions inside the eye and can be used to “see” the back of the eye when there is no other physical way to do so, for example where there is a dense cataract or bleeding inside the eye.
This scan is most commonly used to obtain information regarding the “topography” or curvature of the cornea or “crystal window” of the eye. It can be used to diagnose and monitor dry eye, corneal scars and keratoconus. It is also routinely used as an adjunct in deciding upon the most appropriate intraocular lens choice for patients undergoing cataract surgery.
