Some issues Dr. Robert J S Mack, MD, MD P C can help you with:

Eye Problems

Millions of people every year have problems with their eyes. Some of the most common eye problems are refractive disorders, glaucoma, diabetic retinopathy, macular degeneration, and cataracts.

Refractive disorders happen when the shape of the eye doesn't let allow someone focus very precisely. They might be myopic (nearsighted), hyperopic (farsighted), or have an astigmatism, which is a focus problem caused by the cornea. Refractive disorders can be corrected by glasses or contacts.

Glaucoma is the leading cause of blindness in the United States. It happens when fluid pressure builds up within the eye and damages the optic nerve. It is treated with medications and surgery.

Diabetic retinopathy is a common complication of diabetes. The retina is tissue at the back of the eye that is filled with numerous, tiny blood vessels. When diabetes damages these delicate blood vessels, they burst or leak, leading to blind spots and blurred vision. Diabetic retinopathy can be treated with laser therapy and surgery, but often vision cannot be restored.

Macular degeneration is common in older adults. The macula is the central part of the retina and is responsible for crisp center vision. Over time, the cells in the macula begin to die, making central vision blurry. An early symptom of macular degeneration is that straight lines appear wavy.

Cataracts happen when the clear lens in the front of the eye becomes cloudy, making things look blurry or faded. They are extremely common in older people. By age 80, more than half of all Americans will have had a cataract. In early stages, prescription glasses and magnifying lenses can help. As the cataracts get worse, surgery to replace the lens may be the best option.

More than just one of the five senses, the eyes are heavily relied upon to communicate, work, and get around every day. It's important to have regular eye exams for vision stays in good shape for years to come.

I've been seeing Dr. Mack for a while. I've had chronic dry eye disease for a very long time. I saw doctor after doctor and all they ever told me was here use this prescription drop. When the problem didn't get better I gave up doctor after doctor but it hurt so bad so I tried one more doc. I literally saw some random review of him on the internet and tried him out. It was no doubt a process but he explained it all to me from the beginning so I understood. My eyes have not felt this good in 20 maybe 30 years. And he keeps working with me. I would recommend him to anyone anytime. There may be a wait at times ... but I'm telling you it is worth it.
