What is PCV in fundus diseases?

Generally, PCV in fundus diseases refers to polypoidal choroidal vasculopathy, an eye condition characterized by the abnormal growth of choroidal blood vessels forming polyp-like structures, which may affect vision. If concerned, it is advisable to seek medical consultation promptly. Detailed analysis is as follows:

PCV primarily occurs in the choroid layer, where abnormal blood vessels gradually proliferate and form polyp-like protrusions. These protrusions are prone to rupture and bleeding, causing blood or exudate to accumulate beneath the retina, disrupting the normal retinal structure and impairing visual signal transmission, thereby leading to vision problems.

In the early stages, patients may experience blurred vision or floating dark spots in their visual field. As the disease progresses, symptoms such as distorted vision and visual field defects may appear. If the polypoidal vessels bleed significantly, vision can rapidly deteriorate. Some patients may also experience eye pressure, pain, or discomfort, with symptoms typically affecting one eye.

Upon noticing similar symptoms, prompt fundus examination at an ophthalmology clinic is recommended to confirm whether PCV is present. It is important to avoid strenuous exercise or eye trauma in daily life to reduce the risk of vessel rupture. Once diagnosed, patients should follow medical advice for standardized treatment and undergo regular fundus check-ups to prevent further progression of the disease.
