Bring Hope Back to Patients with Late-Stage Age-Related Macular Degeneration (AMD)

Late-Stage Age-Related macular degeneration (AMD) is the most advanced form of AMD, the leading cause of legal blindness in the U.S. (1) Currently there is no known treatment that can cure for Late-Stage AMD (bilateral geographic atrophy or disciform scars on both eyes).

Central vision loss resulting from Late-Stage AMD cannot be corrected with glasses, contact lenses, anti-VEGF injections, or surgically implanted intraocular lenses (IOLs). (1) Individuals with this level of bilateral vision loss may use external appliances such as hand-held magnifying eyeglasses or a head-mounted telescope in order to enlarge images onto the retina. There are other assistive devices that increase illumination to enhance visual acuity. However, these devices have inherent limitations known to ophthalmologists and other eye care specialists (e.g., limited field of view, disruption of image stability; vestibular-ocular reflex issues with head motion; poor compliance and utilization; and limited utility in dynamic ‘on-the-go’ or social situations).

Implantable Telescope Prosthesis Mechanism of Action

Samsara Vision’s FDA-approved telescope prosthesis (Implantable Miniature Telescope by Dr. Isaac Lipshitz), or IMT, is indicated for patients with End-Stage AMD. Although the IMT does not completely reverse all vision loss due to AMD, it has been shown to significantly improve both central visual acuity and quality of life, which can make a profound and meaningful impact on your patient’s interaction with their world around them. (1,2) The micro-optical telescope is implanted in one eye to magnify objects onto healthy photoreceptors in areas surrounding the macula. This increases the image size and resolution afforded to the perimacular retina. The telescope-implanted eye is then used for central vision; the non-implanted eye is used for peripheral vision. A multidisciplinary team led by a Retina Specialist provides patient identification, candidacy assessment, follow-up, and visual training/rehabilitation.
