Proliferative vitreoretinopathy
Proliferative Vitreoretinopathy (PVR) (pronounced: pro-lif-er-a-tive vito-ret-in-op-a-thy) is a medical condition that occurs as a complication of retinal detachment, and it is characterized by the growth of membranes on both surfaces of the retina and within the vitreous gel.
Etymology
The term "Proliferative Vitreoretinopathy" is derived from the Latin word proles (offspring), ferre (to bear), vitreus (glassy), retina (net), and pathos (suffering).
Symptoms
The symptoms of Proliferative Vitreoretinopathy include vision loss, blurred vision, and visual field loss. These symptoms are due to the contraction of the membranes which cause retinal detachment and retinal fold.
Diagnosis
The diagnosis of Proliferative Vitreoretinopathy is made by a retinal specialist using ophthalmoscopy and ultrasound imaging. The doctor may also use optical coherence tomography to assess the extent of the retinal detachment.
Treatment
The treatment of Proliferative Vitreoretinopathy involves surgery to remove the membranes and to reattach the retina. This may involve a vitrectomy, where the vitreous gel is removed and replaced with a gas or silicone oil.
Prognosis
The prognosis for Proliferative Vitreoretinopathy is variable. Some patients may regain some vision, while others may have severe vision loss despite treatment.
