First, direct ophthalmoscopy requires substantial practice for the examiner to be able to view the retina and optic nerve. 4Īlthough direct ophthalmoscopes are widely available in most medical settings, its usefulness is limited by several practical difficulties. 1, 2 Indeed, misdiagnosis or diagnostic uncertainty is reported in over one-third of neurological consultations in the emergency department, 3 and the funduscopic examination often helps identify those serious conditions that would have been missed using only other aspects of the physical examination.

1 Abnormalities of the optic nerve, retina, and choroid can offer clues to the etiology of neurologic disorders, as well as alert the neurologist to underlying systemic diseases that may be contributing to a patient’s neurological condition. The possibility of telemedical consultation offered by digital retinal photography has already increased access to timely and accurate subspecialty care, particularly for underserved areas.Įxamination of the ocular fundus is a fundamental component of the neurologic examination, providing the only opportunity for non-invasive, direct observation of neurologic tissue and its microvasculature. Additionally, several population-based studies have used retinal imaging to relate ophthalmic abnormalities to the risk of hypertension, renal dysfunction, cardiovascular mortality, subclinical and clinical stroke, and cognitive impairment. Non-mydriatic retinal photography has recently gained relevance as a helpful tool for diagnosing neuro-ophthalmologic disorders in the emergency department. Retinal photography has a high sensitivity, specificity, and inter-/intra-examination agreement compared to in-person ophthalmologist examination, suggesting that photographs can be used in lieu of ophthalmoscopy in many clinical situations. Advances in optical technology have made it easier to obtain high-quality retinal imaging, even without pupillary dilation. OCT technology was previously only available in hospitals and large ophthalmological centres.Ocular fundus imaging is routinely used to document and monitor disease progression in ophthalmology.Helps the doctor detect and monitor signs of glaucoma, cataracts, macular degeneration and other eye diseases.Helps the doctor detect and monitor signs of general health problems like high blood pressure and diabetes.

This is NOT an x-ray and the eye is not exposed to any harmful radiation Retinal photography takes a digital picture of the retina similar to a digital camera.Why you should do OCT and Retinal Photography: The OCT has been invaluable in the detection and diagnosis and treatment of eye diseases such as glaucoma, diabetic retinopathy and macular disorders. It is similar to an MRI but the eye structures are seen instantly and without any harmful radiation to the eye. It is a very specialized piece of equipment that allows the doctor to see within the layers of the retina and other structures of the eye. OCT stands for Optical Coherence Tomography. Retinal photographs should be taken every year in order for the optometrist to properly monitor any changes in your eyes and your overall health. This is the most advanced retinal imaging technology and only a handful clinics have it. At our Eaton Centre and Woodbine Centre locations, we have Optomap technology that can take ultra-wide digital retinal scans and imaging (undilated or dilated). This service is highly recommended because it allows the doctor to examine the retina in detail and the picture serves as a permanent record for future reference. Retinal photography is a service that uses a specialized camera to take a picture of the retina. Also, examination of retinal blood vessels and the optic nerve allows the optometrist to assess a patients overall health. It is very important for the retina to be healthy to maintain good vision. It serves the same function as film in a camera. The retina is a thin, light sensitive layer of tissue that lines the back surface of our eye and allows us to see.
