Forms of Macular Degeneration

There are two forms of macular degeneration, dry (non-neovascular) or wet (neovascular). The term neovascular refers to the growth of new blood vessels.

Dry AMD (non-neovascular)

Dry AMD is the most common form of the disease, making up about 85%-90% of all cases of AMD. It is characterized by blurred central vision or blind spots, as the macula begins to deteriorate. Dry AMD is an early stage of the disease and is less severe than the wet form,.

Dry AMD occurs when the aging tissues of the macula begin to thin out and break down. Tiny pieces of white or yellowish protein called drusen begin to appear, which are thought to be deposits from the macular tissue as it deteriorates. The appearance of these drusen are often what leads to a diagnosis of AMD during an eye exam.

With dry AMD vision loss happens gradually, however, the dry form can progress to wet AMD rapidly. There is currently no cure for dry AMD, however there is research that shows that some people can benefit from supplemental vitamin therapy including antioxidants, lutein and zeaxanthin.

Wet AMD (neovascular)

Wet AMD is less common occurring in only about 10 percent of those with AMD. AMD is classified as Wet AMD when abnormal blood vessels begin to grow under the retina and leak fluid and blood into the macula, resulting in blind spots and a loss of central vision. Wet AMD can cause more damage to vision and permanent scarring if not treated quickly, so any sudden blur in vision should be assessed immediately, especially if one is aware that they have AMD. Usually vision loss happens faster and is more noticeable than in dry AMD so the quicker it is treated, the more vision you can preserve.

Dear Richie Eye Clinic & LASIK Center Family and Friends,

As we head into the Holiday Season and the New Year, I have some news to share.

As many of you know, we have added some new doctors to our team in the last couple of years. Dr. Josh Spedding OD, our new Optometrist, joined us last summer and is currently seeing patients in both our Northfield and Faribault offices. We are thrilled to have Dr. Spedding on our team and welcome him and his family to the area.

Dr. Cory Miller, MD joined us in 2021 and we welcomed Dr. Mike Reinsbach, MD to our team this past summer. Both are Board Certified Ophthalmologists and skilled surgeons specializing in High Technology Cataract Surgery with Advanced Lens Implants, LASIK, Retinal injections, MIGS Surgery for Glaucoma, as well as the usual medical and surgical management of eye disease.

With the addition of these high performing providers, I am transitioning my role in 2023 to concentrate on Practice Development while continuing to serve as the Medical Director overseeing our practice protocols and procedures. Dr. Miller and Dr. Reinsbach will be assuming my day-to-day patient care duties.

I have done my best over the past several months to tell everyone of this transition plan while personally introducing Dr. Miller and Dr. Reinsbach; please accept my apologies if I missed any of you during this time.

Rest assured, we will continue our commitment to providing cutting edge care. Starting in 2023 look for Dropless Cataract Surgery, Light-Adjustable Lens Implants, and so much more…

Thank you for the Trust and Confidence you have shown me over the past 32 years. Please feel free to call us at (507) 332-9900 for questions, concerns, or clarification.

Sincerely,

Mike Richie, MD
