At VRM Toronto, we are proud to offer our patients the very best in retinal care through our advanced retinal diagnostic imaging technology and access to vitreoretinal surgical services as described below.
Vitreoretinal Surgery & Cataract Surgery
We are pleased to offer access to vitreoretinal surgery along with advanced cataract surgery services. We believe in timely access to surgical care in a safe and comfortable environment for our patients. Our surgeons have experience with both simple and complex cataract and vitreoretinal diseases and are dedicated to maximizing the visual outcomes of all our patients in each situation. At VRM we look forward to reviewing your surgical options at your visit.
Laser Treatment for Vitreous Floaters (Vitreous Opacities)
Vitreous floaters are a common result of aging of the gel in the eye and are often associated with posterior vitreous detachment (PVD). Occasionally, floaters are associated with potentially blinding pathology, such as retinal tear, retinal detachment, vitreous hemorrhage, or inflammation. At VRM we offer options for treating visually significant vitreous opacities (or floaters) using a novel yag laser. Click here to learn more.
Angiography is a well-established procedure used to view circulation and leaking or damaged blood vessels in the retina that commonly occur in diseases such as diabetic retinopathy, vascular occlusions, age-related macular degeneration, central serous chorioretinopathy, and hypertensive retinopathy. Fluorescein angiography uses a bright yellow contrast dye to show the circulation of the retinal vessels. Indocyanine Green angiography uses a green-colored dye to highlight the choroid, a layer deeper than the retina. In both types of angiography, the dye is injected into the arm and a rapid sequence of pictures are taken to view the dye as it flows into the eye. Both tests only takes a few minutes to complete and provide vital information to help the physician determine the best course of treatment.
Recent advances in imaging have allowed us to visualize the entire retina in a single photograph. This can be very helpful since changes in the retina sometimes extend beyond what can be visualized with a standard fundus (retina) camera. In these cases, the best option may be to document the pathology with an ultra-widefield camera. At VRM Toronto, we have helped to pioneer the advancement of this technology. This approach to photographing the retina has revolutionized the diagnosis, treatment, and monitoring of conditions affecting the periphery of the retina that range from vascular disorders to retinal detachments and tumors.
Fundus Autofluorescence is a non-invasive imaging modality which evaluates the health of the pigmented cells of the retina: the retinal pigmented epithelium (RPE). These cells have a number of functions, the most important of which is to connect to our vision cells (rods/cones). In conditions where the RPE is damaged, such as retinal degenerations (retinitis pigmentosa, age-related macular degeneration, central serous retinopathy), autofluorescence imaging can assist in evaluating the health of the RPE cells and in providing a better understanding of the status of the retinal condition.
OCT Angiography (OCTA) is a scan that detects the motion of flowing blood cells. OCTA creates an image similar to intravenous angiography, but without the injection of contrast dye, making this a non-invasive alternative to the traditional procedure. It is used as an adjunct to traditional OCT to identify abnormal blood vessels in Age-Related Macular Degeneration, Retinal Vein Occlusion(s), and Diabetic Retinopathy as well as other retinal vascular diseases.
Swept-Source Optical Coherence Tomography
Swept-Source Optical Coherence Tomography is the newest generation OCT that utilizes rapidly tuned frequencies of light over a broad bandwidth, allowing very fast, deep, and wide scanning of the retina and adjacent tissues with good penetration through cataracts and blood. This provides a more detailed cross-sectional view of the eye, improving recognition of structures that are unable to be seen on conventional OCT scans, such as conditions that affect the choroid and vitreoretinal interface.
Microperimetry allows for precise mapping of patients' vision by examining the central portion of the retina known as the macula. This technology is a step forward from the traditional eye chart and, in eyes with retinal disease, can be an important tool in understanding the sensitivity of the retina and in pinpointing the cause of visual problems. Results from microperimetry can be correlated with other imaging modalities, such as angiography, or OCT to better diagnose a retinal condition.
