Vitreomacular Traction
Vitreomacular traction (VMT) is caused by an abnormal posterior vitreous detachment (PVD). The vitreous gel lies inside the eye and provides support for the eye to develop properly. As we age, the vitreous gel naturally weakens and breaks down.
At some point in life, a PVD will occur when the vitreous gel collapses away and separates from the retina. In VMT there is an abnormally strong attachment between the macula (part of the retina responsible for central vision) and the vitreous. This stops the separation and instead causes pulling on and potentially distortion of the macula.
FAQ
What are the symptoms of VMT?
Some patients may not have any symptoms, while others may notice a blurring or some distortion of their central vision. Symptoms may include:
- Distorted or wavy vision
- Flashes of light
- Difficulty reading or recognising faces
If you are experiencing any of these symptoms, it is important to consult with one of our ophthalmologists for a proper diagnosis and treatment plan.
How do you treat VMT?
Many patients do not require treatment if their vision is not being affected by VMT. However, there is a small risk of a macular hole developing and some individuals feel reassurance with regular monitoring of the condition with regular ophthalmic examinations and scanning.
A vitrectomy treatment is recommended if the visual symptoms are affecting quality of vision.
What is VMT surgery?
During this surgery, the vitreous gel, that is causing the traction on the macula, is carefully removed. In some instances where a macular hole is present, a gas bubble may be inserted to help flatten the hole and encourage healing. A vitrectomy procedure can typically last between 1 to 2 hours and is performed with either local or general anaesthetic, as an outpatient procedure.
Following the procedure, a gas bubble inside the eye is applied by the consultant and patients are usually required to maintain a face-down position for a certain period to support the gas bubble in correcting the retinal condition.
What is the recovery from this surgery?
Following the surgery, adhering to important post-operative care and recovery tips is essential for ensuring a complete and successful healing process. Here are some suggestions:
- Follow all post-operative care instructions by your ophthalmologist
- Avoid rubbing or putting pressure on the treated eye
- Avoid strenuous activities or heavy lifting
- Attend follow-up appointments for monitoring and evaluation of your eye’s healing process
It typically takes several weeks to achieve complete healing and restoration of vision.
What vision can I expect after VMT surgery?
Patients who have undergone vitrectomy surgery for VMT may experience a gradual improvement in their visual symptoms over time as the eye heals. It’s important to note that while the surgery can help relieve the traction on the macula and improve symptoms, it may not fully restore vision to its pre-VMT state in all cases.
