Diagnostic tools

The following tools are available to help you and your eye doctor identify signs of symptomatic VMA:

  • Amsler grid
  • Optical coherence tomography (OCT) scan

Both are simple tests that can be performed at your eye care professional’s office or at home.

Amsler grid

The Amsler grid is a tool that eye doctors use to detect vision problems resulting from damage to the macula.

Optical coherence tomography

If you report symptoms such as blurred vision or wavy lines in your vision, your eye care professional can confirm whether you have symptomatic VMA by using technology called optical coherence tomography (OCT). OCT is a noninvasive technique that uses light to visualize the layers below the eye's surface.

OCT of a Normal Eye

This OCT scan is from an aging eye
and shows no signs of the vitreous
and macula sticking together.

OCT of a Patient with Symptomatic VMA

This OCT scan clearly shows that
the vitreous is stuck to and pulling
on the macula.

Untreated symptomatic VMA

As can be seen in the OCT image, when the vitreous sticks to the macula of a patient with symptomatic VMA, it can start pulling on it. This may lead to a macular hole, so it is important for you to report all symptoms and any changes in your vision.

If your eyesight gets worse and your eye care professional is concerned about more harm being done to your eye, treatment may be recommended.

Don't wait. Take action, go visit you eye care professional to help protect your vision from this progressive condition.

Indication

JETREA® (ocriplasmin) Intravitreal Injection, 2.5 mg/mL, is a proteolytic enzyme indicated for the treatment of symptomatic vitreomacular adhesion.

Important Safety Information
Warnings and Precautions
  • A decrease of ≥ 3 lines of best-corrected visual acuity (BCVA) was experienced by 5.6% of patients treated with JETREA and 3.2% of patients treated with vehicle in the controlled trials. The majority of these decreases in vision were due to progression of the condition with traction and many required surgical intervention. Patients should be monitored appropriately.
  • Intravitreal injections are associated with intraocular inflammation/infection, intraocular hemorrhage and increased intraocular pressure (IOP). Patients should be monitored and instructed to report any symptoms without delay. In the controlled trials, intraocular inflammation occurred in 7.1% of patients injected with JETREA vs 3.7% of patients injected with vehicle. Most of the post-injection intraocular inflammation events were mild and transient. If the contralateral eye requires treatment with JETREA, it is not recommended within 7 days of the initial injection in order to monitor the post-injection course in the injected eye.
  • Potential for lens subluxation.
  • In the controlled trials, the incidence of retinal detachment was 0.9% in the JETREA group and 1.6% in the vehicle group, while the incidence of retinal tear (without detachment) was 1.1% in the JETREA group and 2.7% in the vehicle group. Most of these events occurred during or after vitrectomy in both groups.
  • Dyschromatopsia (generally described as yellowish vision) was reported in 2% of all patients injected with JETREA. In approximately half of these dyschromatopsia cases there were also electroretinographic (ERG) changes reported (a- and b-wave amplitude decrease).
Adverse Reactions
  • The most commonly reported reactions (≥ 5%) in patients treated with JETREA were vitreous floaters, conjunctival hemorrhage, eye pain, photopsia, blurred vision, macular hole, reduced visual acuity, visual impairment, and retinal edema.
