What is Choroidal Neovascularization (CNV)? Symptoms & Causes

 If you do not know what Choroidal Neovascularization is, this blog post will provide all your answers. Besides that, if you are a PG student, you must stay tuned until the end because we have something exciting to share with you.


So let's start!


Choroidal Neovascularization occurs when new and abnormal blood cells emerge from a layer of blood vessels (the choriocapillaris) via a thin barrier, the Bruch's membrane and enter into areas under the retina.


In other words, when any person gets diagnosed with Choroidal Neovascularization, they experience extreme vision loss as the new blood vessels that are growing are unlike the normal ones. 


The reason behind the loss of vision is that when these damaging blood vessels grow in the macula, the core region of the retina that allows us to see the world and its light, they can cause discomfort to the patient and cause painless loss of vision. 

Causes of Choroidal Neovascularization


CNV can happen due to many factors such as:


  • Extreme nearsightedness

  • Certain eye injuries

  • Damaged brunch membrane

  • Any kind of physical injury or trauma

  • Inflammatory diseases

  • Genetic or hereditary disorders

Symptoms of CNV

You may not notice at first, but many signs point you towards CNV. Its symptoms include the following:


  • Blurred vision

  • Distorted images

  • Flickering of lights

  • A blind or dark spot in the centre

  • Change of color vision

Experiencing these symptoms might be concerning for the patients. This is why a doctor with advanced skills and knowledge must diagnose and treat them.
