Inflammatory conditions such as uveitis are the most common conditions responsible for this type of retinal detachment. They commonly grow in response to proliferative vitreoretinopathies, most notably diabetic retinopathy.(5) ExudativeĮxudative retinal detachment occurs due to an underlying condition causing buildup of fluid (exudate) between the neurosensory retina (photoreceptor layer) and the retinal pigment epithelium (RPE). Vitreous membranes are usually gliotic, fibrous, vascular, or a combination. No tears or holes are present in this type of retinal detachment. Tractional retinal detachment occurs when vitreous membranes pull on the retina separating it from the RPE. These full-thickness breaks, most commonly due to and held open by vitreoretinal traction, allow fluid from the liquified vitreous to move under the neurosensory retina and further separate it from the retinal pigment epithelium. It affects approximately 0.007-0.018% of the population yearly.(4) Rhegma means “break” in Greek, and these retinal detachments are due to full-thickness breaks in the retina. Rhegmatogenous retinal detachment (RRD) is the most common form of retinal detachment. These include rhegmatogenous retinal detachments, tractional retinal detachments, and exudative retinal detachments. However, in the simplest terminology, there are three primary forms of retinal detachment. There are many classification schemes for retinal detachment. The choroid is a vascular layer immediately posterior to the RPE which provides blood to the outer layers of the retina (the inner layers of retina supplied by branches of the central retinal artery). It recycles vitamin A for use by the retina in the visual cycle, and it keeps fluid from accumulating underneath the retina. It is responsible for nourishing the retina. The retinal pigment epithelium is between the retina and the choroid. Also, the vitreous breaks down and liquefies as we age.Įxternal and posterior to the retina are the retinal pigment epithelium (RPE) and the choroid. It comprises 80% of the volume of the eye and is responsible for providing mechanical support for our eyes during development.(3) However, there is little evidence of a functional purpose of the vitreous after our eyes have fully developed. Think of the vitreous as clear jelly inside the eye comprised of type II collagen and hyaluronic acid. Internal and anterior to the retina is the vitreous. This area of high photoreceptor density is important in retinal detachment as its condition dictates the prognosis of the disease. More specifically, the highest proportion of photoreceptors is in a central 1.5mm zone called the fovea. The macula has a high concentration of photoreceptors and is responsible for capturing central vision. The central portion of the retina is the macula. It is bordered anteriorly by the vitreous and posteriorly by the choroid. The retina is comprised of photoreceptors, neurons, and support cells. It is a thin layer that coats the internal border of the posterior eye. Ltd, Japan since 2015, Optos is approaching its 30th anniversary and proud to be recognized as a leading provider of devices to eye care professionals to provide a more complete approach to patient care.Think of the retina as the film of the camera. More than 2,500 published and ongoing clinical trials as well as thousands of case studies and testimonials show the long-term value of optomap imaging and OCT in diagnosis, treatment planning, and patient engagement.Īs a division of Nikon Co. This combined device facilitates the early detection, management and effective treatment of disorders and diseases evidenced in the retina such as retinal detachments and tears, glaucoma, diabetic retinopathy, and age-related macular degeneration. The most recent innovation from Optos integrates ultra-widefield retinal imaging and image-guided Optical Coherence Tomography (OCT). Our core products produce high resolution optomap images of 82% or 200◦ of the retina, something no other imaging device is capable of in a single comfortable capture. You will find optomap systems in many independent High Street optometrists, as well as eye clinics at Great Ormond Street Hospital in London and Harvard Medical Center in Massachusetts. Today, millions of patients around the world have benefited from optomap® retinal imaging. Optos was founded by Douglas Anderson with the goal to make a patient-friendly device to capture a digital ultra-widefield image of the retina. When a five-year-old boy was blinded after a regular eye exam failed to spot a retinal detachment, his father made it his life’s work to help eye care professionals by revolutionising retinal imaging.
