Eye & Retinal Imaging

Retinal and Optic nerve OCT scans (Zeiss CIRRUS 6000 OCT) allow high resolution non-invasive imaging scans from the front of the eye (cornea, iris, lens) to the back of the eye (macula, retina, and optic nerve). OCT scans are vital to the diagnosis and management of a wide range of eye conditions, including glaucoma, macular degeneration, diabetic retinopathy, epiretinal membrane, macular hole and other retinal conditions.

OCT Angiography allows non-invasive imaging of the retinal blood vessels, taking glaucoma and retinal disease management and treatment planning to the next level. OCT Angiography is a quick and comfortable test that allows the doctor to assess the blood flow patterns in the patient’s retina without using radiation or the need for intravenous dye. This test assists in the diagnosis and treatment of conditions such as diabetic retinopathy, macular degeneration (AMD) and retinal vein occlusion.

Visual field testing maps out your peripheral vision and is important in assessing conditions such as glaucoma, optic nerve swelling, retinal diseases, fitness to drive, as well as certain neurologic conditions such as stroke. Eastwood Eye Specialists has the latest equipment, Zeiss Humphrey Field Analyzer 3, which is the internationally accepted gold standard in visual field testing and used by leading glaucoma specialists.

Ocular biometry is a critical part of planning cataract surgery. This equipment measures the shape and size of the patient’s eye including the curvature of the cornea (front window of the eye), the relative position of the lens (cataract) within the eye, as well as the length of the eye, amongst several other important parameters that makes each person’s eye unique. These measurements are then analyzed by complex mathematical prediction formulae to allow the eye surgeon to select the most suitable intraocular lens implant (IOL) for the patient for their desired visual outcome from cataract surgery. At Eastwood Eye Specialists, our surgeons use the latest IOL Master 700, which uses the latest SWEPT Source Biometry technology, allowing Central Corneal Topography for precise measurement of astigmatism as well as “total keratometry” that directly measures both the front and back curvatures of the cornea. Our biometry equipment also acquires reference images of the patient’s eye, so that this information is then used in the operating theatre, where the image is then used for intra-operative matching with the live eye image as seen through the operating microscope during surgery. This “markerless toric IOL implantation” technique allows the most precise implantation of the new lens during cataract surgery.

Ultra-Widefield (UWF) Retinal Camera obtains high-resolution images from the macula and optic nerve to the far periphery of the retina. Such camera images far greater and wider area of the back of the eye (up to 267 degrees field of view) than traditional retinal cameras (45-50 degrees view). At Eastwood Eye Specialists, we have the latest Zeiss CLARUS 700 fundus camera that captures true colour, high-resolution retinal images down to 7 microns in an expansive ultra-widefield view.

Fundus Fluorescein Angiography (FFA) involves taking a series of photos of the retina whilst a fluorescent dye passes through the retinal blood vessels. This specialized test is used by Medical Retina specialists to diagnose and treat certain sight-threatening retinal conditions such as diabetic retinopathy, retinal vascular occlusion, macular degeneration and uveitis (inflammatory eye disease). FFA provides additional information such as leakage from blood vessels and more extensive imaging than what is possible with OCT Angiography.

Fundus Autofluorescence (FAF) is an important non-invasive retinal imaging modality that detects the natural fluorescent properties of lipofuscin within the specialized cells, called retinal pigment epithelium, that line the back of the eye. Unique FAF patterns are detectable in various eye conditions such as retinal atrophy in dry macular degeneration (AMD), central serous retinopathy (CSR), degenerative retinal conditions such as Retinitis Pigmentosa, as well as optic nerve drusen.
