Age-Related Macular Degeneration

What is Macular Degeneration?

Macular degeneration, also known as age-related macular degeneration (AMD), is a progressive eye disease that primarily affects the macula, the central part of the retina responsible for sharp, central vision. It is a leading cause of vision loss in individuals over the age of 50, impacting activities such as reading, driving, and recognizing faces.

Types of Macular Degeneration:

There are two main types of macular degeneration: dry AMD and wet AMD. Dry AMD, which is more common, occurs when the lightsensitive cells in the macula gradually break down, leading to blurred or distorted vision. Wet AMD, although less common, is more severe and occurs when abnormal blood vessels grow beneath the retina, leaking fluid and blood, causing rapid vision loss.

Causes and Risk Factors

While the exact cause of macular degeneration is not fully understood, several factors can increase the risk of developing the condition. These include age, genetics, smoking, obesity, high blood pressure, and prolonged exposure to UV light.

Symptoms of Macular Degeneration

Macular degeneration often progresses slowly and may go unnoticed in its early stages. Common symptoms include:

Blurred or distorted central vision
Difficulty reading or recognizing faces
Dark or empty areas in the central vision
Straight lines appearing wavy or distorted

Types of Macular Degeneration Tests

Visual Acuity Test

This test measures how well you can see at various distances. It's often performed using an eye chart to assess central vision clarity.

Dilated Eye Exam

During a dilated eye exam, eye drops are used to enlarge the pupil, allowing the eye care professional to examine the retina and optic nerve for signs of Macular Degeneration

Amsler Grid Test:

The Amsler Grid is a tool used to detect distortions or changes in central vision. Patients are asked to focus on the grid while reporting any areas of distortion or missing lines, which may indicate Macular Degeneration.

Optical Coherence Tomography (OCT)

OCT is a non-invasive imaging test that provides high-resolution crosssectional images of the retina. It helps detect abnormalities in the macula, such as fluid accumulation or thinning of the retinal layers.

Patient Reviews

We saw Dr Sevigny in the Arcadia office on an emergency visit for my 2 year old. I would highly recommend him to anyone who asks! Dr Sevigny and his staff showed immediate attention to my toddler’s pain by getting us in within ten minutes of my initial phone call. We were very happy with our unplanned experience and want to thank Dr Sevigny and his staff for doing an amazing job as well as showing compassion and great care. Thank you so much!

My son had an all the sudden vision problem today at school and when I called the office Dr Mark wasn't working but he came to the office to evaluate my son for a possible Retna tear. Luckily it was not but a huge thank you for such wonderful service from the staff and Dr. Wonderful to have such family like service in our little town

If it wasn't for Dr. Mark Sevigny I would be blind. He also discovered a genetic eye condition in me that hadnt been found in me in 22 years of wearing glasses since age 2 1/2 that no other eye Dr. had noticed before. He has treated me for multiple other conditions, and has been there for me since I first walked into his practice. The Office Staff now treat me like a regular with how often I have to go for testing, they have watched my 3 year old grow. It's like my 2nd family there.

I've always had quick yet thorough appointments. I've been with much of this staff for as long as I have been in need of glasses (20+ years). As a young child, this was the only doctor I was not afraid to visit, and now continuing with them as an adult I continue to feel very comfortable and welcomed! Major shout out to the reps who have taken the time to help me select frames and lenses. Even though I haven't always known what I wanted, they were patient and willing to assist me. 10/10 would recommend their office!
