Proliferative Vitreoretinopathy (PVR) is a complication that can occur after retinal detachment surgery. It is characterized by the growth of cells and scar tissue on the retina and vitreous gel, which can cause the retina to wrinkle or detach again.
Causes[edit]
PVR is most commonly caused by an inflammatory response to a retinal tear or detachment. This response can lead to the proliferation of cells and the formation of scar tissue. Other factors that can contribute to the development of PVR include genetic predisposition, the presence of certain chemicals in the eye, and previous eye surgeries.
Symptoms[edit]
The symptoms of PVR can vary depending on the severity of the condition. They may include:
- Decreased vision
- Flashes of light
- Floaters in the field of vision
- A loss of peripheral vision
- A sudden decrease in vision
Diagnosis[edit]
PVR is diagnosed through a comprehensive eye examination. This may include a visual acuity test, a dilated eye exam, and an optical coherence tomography (OCT) scan. In some cases, an ultrasound of the eye may also be performed.
Treatment[edit]
The treatment for PVR is primarily surgical. The goal of surgery is to remove the scar tissue and reattach the retina. This is often done through a procedure called a vitrectomy, in which the vitreous gel is removed from the eye and replaced with a gas or oil bubble. In some cases, a scleral buckle may also be used to support the retina.
Prognosis[edit]
The prognosis for PVR varies depending on the severity of the condition and the success of the treatment. In some cases, vision may be significantly improved. However, in other cases, vision loss may be permanent.
