Global Retina Institute is an Arizona-based eye care practice founded by Dr. Robin Ross, focused on retinal health, advanced diagnostics, and compassionate patient care. Serving Central Phoenix and surrounding communities, the institute treats and manages a broad range of medical and surgical vitreous and retinal conditions, including macular degeneration, diabetic retinopathy, retinal tears, and detachments.

Its services include comprehensive retinal evaluations, high-resolution imaging, diagnostic testing, and surgical and nonsurgical treatments. The practice also offers laser floater treatment and dry eye care, and introduces newer technologies such as Valeda by LumiThera. Patients can access a portal, educational resources, mobile check-in, and appointment scheduling.

Care and payment options include self-pay, traditional Medicare, a Medicare membership for same-day multimodal testing, and the GRI Vision Individualized Program. This concierge program provides personalized evaluations, monitoring, priority scheduling, and long-term vision-preservation planning. Beyond Arizona, Global Retina Institute aims to advance retinal research, teach other clinicians, and help expand access to eye care in developing countries, including through efforts in Zambia
