While therapeutics are available for the treatment of early-stage AMD, there is a lack of interventions for people with advanced AMD. Wet AMD is caused by leakage of blood vessels associated with the retina, whereas dry AMD involves damage to photoreceptors in the macula associated with the build-up of deposits called drusen. dry AMDĪMD can be categorized as either wet or dry AMD. The damage to the cells in the macula, known as macular degeneration, causes a gradual loss of central vision, impairing the ability to view fine details.Īge-related macular degeneration is the leading cause of vision loss in older adults.ĪMD hinders the performance of daily activities, such as reading and driving, and is associated with a decline in quality of life. The macula is the central part of the retina and is involved in sharp, straight vision, also known as central vision. The retina is the innermost layer of the eye, made up of photoreceptors that convert light into nerve impulses. What is age-related macular degeneration?

Overall, this trial showed that the SING IMT appeared to be safe and effective as a low-vision rehabilitation aid in patients with moderate to profound vision loss due to advanced AMD.” “Postoperative changes to the cornea (including changes to the endothelial cell layer) were comparable to those seen in modern cataract surgery. Near visual acuity improved as well,” Wood told Medical News Today. “ that at postoperative month three, 70.83% of patients gained ≥ 2 lines of visual acuity on the eye chart, 58.33% gained ≥ 3 lines, and 25.00% gained ≥ 4 lines of corrected distance visual acuity. Edward Wood, a vitreoretinal surgeon with Austin Retina Associates in Texas who was not involved in the study, said the new technology shows promise. SING-IMT has not yet been approved by the Food and Drug Administration (FDA).ĭr.
It has been approved for use in individuals aged 65 years and older with advanced AMD.Ī second generation of this prosthetic developed by Samsara Vision, Inc., called the smaller-incision new-generation implantable miniature telescope (SING IMT), is designed to reduce the complexity of the surgical process, improve safety, and increase the speed of recovery.Ī recent three-month study suggests that the SING-IMT is safe and improves distance and near visual in people with advanced AMD as well as resulting in lower levels of surgical trauma than its predecessor. This first-generation implant has been described as cost-effective and compatible with other procedures such as cataract surgery.
Previous research has demonstrated that an implantable miniature telescope (IMT) consisting of specialized lenses that serve as a tiny telescope in the affected eye can help reduce AMD-associated deficits in central vision. It is estimated that about 20 million people in the United States have some form of age-related macular degeneration (AMD), a condition that causes central vision loss. A small retrospective study recently showed that the smaller-incision new-generation implantable miniature telescope (SING IMT), an implantable tiny telescope, safely improved both near and distance visual activity.Implantable devices, including sets of lenses that function as a miniaturized telescope with the cornea, have been explored as a potential treatment.There is a lack of effective treatments for advanced AMD, resulting in a lower quality of life and a reduced ability to perform daily activities.Age-related macular degeneration (AMD) is a condition that gradually leads to the loss of central vision due to damage to the macula, the central region of the retina.Share on Pinterest A small, new device that resembles a telescope is being tested as a treatment for age-related macular degeneration.
