Colorado Retina Associates is a thirteen physician, owned and led, sub-specialty eye care practice providing medical and surgical care of vitreoretinal eye disease. Colorado Retina provides comprehensive retinal treatment for age-related macular degeneration (AMD), diabetic retinopathy, retinal vascular disease, retinal detachments, ocular tumors, uveitis/inflammatory eye disease, inherited retinal degenerations and numerous other vitreoretinal conditions.
Uveitis refers to a group of inflammatory and infectious diseases in and around the eye, including iritis, pars planitis, scleritis, birdshot chorioretinopathy and retinal vasculitis. Patients often have systemic autoimmune conditions that are associated with their uveitis.
The macula is the part of the retina responsible for our most detailed central vision and is essential for precise vision. Age-related Macular Degeneration (AMD) is the leading cause of blindness in the US today, affecting approximately 10 million people.
A Retinal Vein Occlusion (RVO) involves blockage of blood trying to leave the eye through the retinal veins, commonly occurring in persons over the age of 55 years and is usually associated with high blood pressure, high cholesterol, diabetes, and/or cigarette smoking.
Diabetes is the leading cause of preventable blindness in the US. There are many ways in which diabetes impacts the eye, including swelling of the macula (the most important, central part of the retina), decreased oxygen delivery, and new growth and bleeding of diseased blood vessels.
An ERM (also known as macular pucker) is a growth of scar tissue over the macula, the portion of the retina providing central vision. Typically due to age related eye changes, ERM development is also associated with a retinal tear and detachment, eye trauma, and diabetes.
Inherited retinal diseases (IRDs) are a group of genetic disorders that affect the retina’s ability to transmit light-related information to the brain. Typically, IRDs cause a slow loss of vision, beginning with decreased night vision and loss of peripheral (side) vision.
The macula is the part of the retina responsible for our most detailed central vision and is essential for precise visual activities like reading and driving. A macular hole occurs when a full thickness defect develops in the very center of the macula, usually due to age related changes.
Intraocular tumors are evaluated with a variety of diagnostic imaging technologies to make a diagnosis and create a personalized clinical plan. Benign lesions are typically monitored but may be treated to improve vision. Malignancies are treated in coordination with oncology teams.
Many conditions can lead to a retinal detachment, in which the retina separates from the back wall of the eye. The typical symptoms of a retinal detachment include floaters, flashing lights, and a shadow in the peripheral vision that can move toward the center of vision.
"I couldn't have been more pleased with this appointment!"
Dr. Courtney completely explained my condition and answered all my questions before I even gave him my list of questions. Dr. Courtney is extremely kind and communicates very well, putting everything in simple to understand language. He is very reassuring, explains available treatment, and is very gracious and willing to be available to care for you in the future. Definite 5 star rating. Thank you Dr. Courtney!!!!
"I'm back to seeing 20/20 again and couldn't be happier!"
I am so thankful for Dr. Courtney! I had multiple retinal tears that he repaired and, later, had a retinal detachment that he also corrected. His office staff has always been so helpful and he takes as much time as you need to understand your issues. Highly recommend Dr. Courtney!
"I highly recommend Dr. Adam and his associates!"
I recently had surgery to correct a macular pucker in my left eye. I am so grateful to have been referred to Dr. Adam and Colorado Retina Associates. Dr. Adam is probably the best doctor I've ever had, bar none. He is beyond competent, explains everything, is patient w/questions (even the repeated ones!) a great listener, kind and caring. In fact, the entire staff at CRA are amazing. They exemplify the best in how medicine should be practiced. I highly recommend Dr. Adam and his associates!
"From the moment I first set foot in the office I was treated with kindness, respect and care."
I was referred to Dr. Adam for a detached retina. From the moment I first set foot in the office I was treated with kindness, respect and care. Dr. Adam explained everything to me in a manner that made sense, every step of the way. After my surgery he was very hands on with my recovery journey and took a very practical, non-aggressive approach to my healing. He did not treat me just like another patient, he was always concerned and when I made strides in the right direction, he was just as happy and excited as I was. The whole staff is great, very easy to work with and super accommodating. I would recommend Dr. Adam and Colorado Retina Associates without hesitation every time. Thank you!
"Dr. Mimi Liu of Colorado Retina Associates is a surgeon of the highest professional expertise!"
For 5+ years I’ve avoided surgeries in both EYES because the surgery name ends with the word ‘PEEL’! OMG! Not only did Dr. Mimi Liu of Colorado Retina Associates meticulously perform this intricate, delicate surgery, but her confident-yet-gracious patient care skills quieted my many fears. She’s a surgeon of the highest professional expertise! If your eye doctor tells you that you need a macular membrane peel, immediately call Colorado Retina Associates and meet with Dr. Mimi Liu!
"The most compassionate team I have ever had to be involved with for my health"
I saw Dr. Hovland for my Ocular Melanoma treatment of Plaque Radiation. He and his staff are the most compassionate team I have ever had to be involved with for my health. They go out of their way for their patients, are very kind and gentle and reassuring about everything. I only wish I was much closer so I could see them often. You will not ever regret seeing these people!
"The care they have given us has gone beyond anyone else we have seen"
We came all the way from Evansville, Indiana to see Dr. Hovland, for the purpose of enucleation due to choroidal melanoma. When we got to Colorado Retina we were immediately comforted by them. They made us feel like we were the only patients they had to see that day. Such a thorough visit; which included much education for us and very specific looking at the mass in my eye. We left Colorado Retina Associates with me having two 👁👁! And being very encouraged! We realize from our visit that things could change in the future; but if they do we'll know we are in amazingly expertise and caring hands.
"Thanks for saving my vision."
