What is Symptomatic VMA?

As a person gets older, the central gel that fills the eye called the vitreous liquefies and loses shape, leading to separation of the vitreous from the retina located at the back of the eye. This separation is a normal part of aging and is called a posterior vitreous detachment (PVD). However, if the separation is not complete, small areas of the vitreous can remain attached to the macula, the part of the retina that is responsible for your sharp, central vision. If this attachment causes the retina to be pulled, the condition is called symptomatic vitreomacular adhesion (symptomatic VMA). It can lead to distortion of your vision, a decrease in vision, and/or a loss of central vision in more severe cases.

Who is at Risk for Symptomatic VMA?

Much like posterior vitreous detachment (PVD), symptomatic VMA typically occurs in individuals over the age of 50 and is most common in elderly individuals over the age of 70. It is also slightly more common in women and nearsighted individuals.

What are the signs and symptoms of Symptomatic VMA?

Symptomatic VMA may lead to various symptoms such as distortion of your vision, a decrease in vision, and/or a loss of central vision.

How Does Symptomatic VMA Damage My Eyes?

Symptomatic VMA is a result of the macula, center of the retina, being pulled. This pulling disrupts the retinal architecture and can lead to several problems such as vitreomacular traction and full thickness macular hole.

Eye care professionals are able to detect symptomatic VMA through a complete, dilated eye examination including an optical coherence tomography (OCT) examination. During the eye exam, the eye doctor widens the pupil of the eye (dilates the eye) with eye drops to allow a closer look at the inside of the eye. The OCT examination provides images of the back of the eye including the vitreous and retina, allowing eye doctors to accurately diagnose symptomatic VMA. Diagnosis is difficult without an OCT examination.

Current options for patients with symptomatic VMA are “watchful waiting,” surgical removal of the vitreous gel (vitrectomy), and intraocular injection of medication.

If you’re a layperson, this is the way you probably think of generics: They’re the exact same products in different packaging.

The FDA agency’s definition of bioequivalence is surprisingly broad: A generic’s maximum concentration of active ingredient in the blood must not fall more than 20% below or 25% above that of the brand name. This means a potential range of 45%, by that measure, among generics labeled as being the same.

There are other differences. The generic must contain the same active ingredient as the original. But the additional ingredients, known as excipients, can be different and are often of lower quality. Those differences can affect what’s called bioavailability — the amount of drug that could potentially be absorbed into the bloodstream.

These and other factors need to be taken into consideration, especially if your medicate is designed to save your eyesight or other vital organs.
