Corneal Transplantation

Corneal Transplantation is a technique for replacing diseased or damaged cornea with clear corneal tissue from a deceased donor. If only a single layer of the cornea is damaged it may be able to be replaced with a partial thickness transplant. If multiple layers or the entire thickness of the cornea is involved then a full thickness transplant is required called a Penetrating Keratoplasty. Unlike transplantation of other organs, most patients that receive a corneal transplant do not need to take powerful oral immunosuppressive medications. Topical steroid drops are used to prevent rejection and control inflammation. At Eyecare Medical Group we partner with Eye Banks across the country to provide our patients with the highest quality graft tissue. We perform several transplants each week using both full thickness and partial thickness techniques. It is from the generosity of people who choose to become organ donors that we are able to pass along the gift of sight to our patients. It is my privilege to assist in the donor’s generosity and an honor to facilitate this sight saving surgery.

Slowing Nearsighted Progression

About Nearsighted or Myopic Progression
Myopia is a common disorder, affecting approximately one-third of the U.S. population. High myopia is associated with an increased risk of sight-threatening problems, such as retinal detachment, choroidal degeneration, cataracts, and glaucoma. Slowing the progression of myopia could potentially benefit millions of children in the U.S. To date, few clinical approaches for myopia control and slowing myopic progression have proven to be consistently effective. Treatment options such as undercorrection of myopia, gas permeable contact lenses, and bifocal or multifocal spectacles have all been proven to be ineffective for myopia control, although one recent clinical trial using executive top bifocal spectacles on children with progressive myopia has shown to decrease the progression to nearly half of the control subjects. The most effective methods are the use of orthokeratology contact lenses, soft bifocal contact lenses, and certain eye drops not specifically approved for this use. We encourage parents children experiencing rapid myopic progression to discuss which if any of these options might be helpful or appropriate for their children.

If you or someone you know has a question about myopic progression or the ways to slow nearsighted prescription increases, feel free to discuss your concerns with us and please call Eyecare Medical Group, 53 Sewall Street, Portland, Maine 04102 at 888-374-2020, visit Eyecare Medical Group, Google+ or facebook.com/eyecaremedicalgroup to schedule an appointment.

Special Eye Exams Predict Diabetic Retinopathy Damage

Recently reported information in Retina Today from research conducted at the Joslin Diabetes Center’s Beetham Eye Institute demonstrated that for people with diabetes who are showing evidence of diabetic retinopathy, it is of important predictive value for us to carefully evaluate lesions not simply the center of the retina, but more importantly those in the periphery of the retina, as these changes generally tell us that the disease will progress more rapidly. What we now know is that these peripheral lesions, which are not detected by traditional eye imaging, correlate very closely with the loss of retinal blood flow called retinal “non-perfusion” which tells us that there is damage to the small blood vessels or capillaries in the retina.

Thus, if you are diabetic and we are following you for retina changes and diabetic retinopathy we may recommend that we take both the routine retina photographs and fluorescein angiography of the central retina as well as the peripheral retina. If this extra measure of safety is required we will advise you of this extra step at the time of your diabetic eye exam.

Fortunately, with early detection, diagnosis and treatment the last decade or so has given us many major success stories for the treatment of diabetic eye disease, including diabetic macular edema (DME), with drugs that target a protein called vascular endothelial growth factor (VEGF). It’s possible that such anti-VEGF drugs might also help to treat peripheral lesions and slow or even eliminate the risk of progression.

If you or someone you know has diabetes, having regular eye exams and testing to prevent vision loss from diabetic retinopathy is an important part of your care. Please schedule a diabetic eye exam by calling Eyecare Medical Group, 53 Sewall Street, Portland, Maine 04102 at 888-374-2020, or visit Eyecare Medical Group, Google+ or facebook.com/eyecaremedicalgroup to schedule an appointment.

Monitoring Multiple Sclerosis with Eye Testing

About Multiple Sclerosis
Multiple sclerosis (MS) is a debilitating neurological disease that can cause patients to experience decreased vision due to optic neuritis, an inflammation of the optic nerve, as well as diplopia or double vision. We believe that MS occurs because there is an abnormal response of the body’s immune system whereby it is directed against the central nervous system (CNS), which is made up of the brain, spinal cord and optic nerves. Within the CNS, the immune system attacks myelin-the fatty substance that surrounds and insulates the nerve fibers as well as the nerve fibers themselves. When any part of the myelin sheath or nerve fiber is damaged or destroyed, nerve impulses traveling to and from the brain and spinal cord are distorted or interrupted, producing a wide variety of symptoms.

About Optical Coherence (OCT) Eye Testing for MS
In our office, we routinely use very precise imaging technology called Optical Coherence Tomography (OCT) as part of evaluation, diagnosis and monitoring glaucoma and retina diseases because it allows us to examine the actual nerve fibers of the retina and the optic nerve.

Recent research has taught us that OCT can be used to monitor the degree of atrophy of specific retinal layers-called the “inner plexiform layer” and “ganglion cell layer”-and used as an as an indicator of neuronal tissue damage in patients with multiple sclerosis (MS). For patients with Multiple Sclerosis this is quite valuable as it gives us a non invasive in office test, that in concert with their neurologists, helps us help patients asses the stability of their disease as well as their response to new medications or treatments.

If you or someone you know has been diagnosed with MS or has questions about the eye problems that can be associated with Multiple Sclerosis, please call Eyecare Medical Group, 53 Sewall Street, Portland, Maine 04102 at 888-374-2020, visit Eyecare Medical Group, Google+ or facebook.com/eyecaremedicalgroup to schedule an appointment.

Dry Eye Discomfort Slows Reading

Dry Eye Slows Reading Speed
Anyone who experiences the symptoms of dry eye is familiar with dryness, discomfort, burning, light sensitivity and even watering that can mark the presence of dry eye disease. But, did you know that dry eye problems and disease can impact visual function? Researchers reporting in Cornea compared visual function using reading tests including the Radner Reading Test, the International Reading Speed Texts [IReST], and the Wilkins Reading Test and studied cognitive function, fatigue, dry eye symptoms, reading acuity, reading rate and blink rate. The results showed significantly lower reading rates in all reading tests in patients with dry eye and a significantly increased fatigue level when reading in dry eye patients.

If you suffer from symptoms of dry eye such as dryness, burning, light sensitivity or watering and have noticed an uncomfortable slowing of your reading ability and even greater eye fatigue or tired eyes when reading, please call Eyecare Medical Group, 53 Sewall Street, Portland, Maine 04102 at 888-374-2020, visit Eyecare Medical Group, Google+ or facebook.com/eyecaremedicalgroup to schedule an appointment.

Dry Eye Disease and Hair Loss

About Dry Eye and Hair Loss
What do dry eye and hair loss have to do with each other? As it turns out, recent research suggests there may very well be a link through your immune system. Alopecia means hair loss. When a person has a condition called Alopecia Areata the hair falls out in round patches on the scalp or elsewhere on the body. Alopecia is not contagious and it is not due to anxiety as some people think. Alopecia is actually due to your immune system attacking the hair follicles and resulting in hair loss. This disease is most occurs in otherwise healthy people. We now know that people with alopecia often suffer from dry eye disease. Researchers examined a series of patients who were previously diagnosed with Alopecia Areata and compared them to a control group who did not have the hair loss problem. They had each patient complete an Ocular Surface Disease Index (OSDI) questionnaire and evaluated their tear film using a Schirmer Test for tear quantity, a tear break-up time test and corneal staining stage tests. Dry eye disease (DED) was diagnosed in 84% of Alopecia Areata patients and in 15% of the controls, and there was a significant difference between the groups. They believe that a certain type of cell mediated autoimmunity has a key role in BOTH Alopecia Areata and dry eye disease and that the inflammatory mechanisms causing Alopecia Areata may trigger dry eye disease or vice versa. Based on this research it is recommended that all patients with Alopecia Areata be examined and evaluated for dry eye disease.

If you or someone you know suffers from Alopecia Areata hair loss and wish to be evaluated for dry eye disease and problems, please call Eyecare Medical Group, 53 Sewall Street, Portland, Maine 04102 at 888-374-2020, visit Eyecare Medical Group, Google+ or facebook.com/eyecaremedicalgroup to schedule an appointment.



Quality of Life after Cataract Surgery

Cataract Surgery Quality of Life
When we think of the impact that cataracts have on people, it is pretty easy to identify that vision decline or loss comes mainly from the blurry cloudy vision that cataracts cause, but also the night vision problems from the glare and haloes associated with cataracts. What is much more important than the vision loss itself is the negative impact on patient’s quality of life. Recent research published in Acta Ophthalmologica studied the effect of patient quality before and after having cataract surgery. The researchers compared patients with no known cataracts of the same age, health and lifestyle to those who had cataracts before and after cataract surgery. When compared with the general population, cataract patients had much lower health-related quality of life (HRQoL) than those without cataracts as measured by five dimensions: seeing, moving, hearing, performing their usual activities and general discomfort and symptoms. Then at 12 months after cataract surgery there was significant improvement in the quality of life index (HRQoL) across these same dimensions. While this seems obvious, it is a reminder that cataracts and vision loss affect more than just vision and reason to avoid suffering if you feel that your vision might be impacting your quality of life.
