Which visual symptom is commonly reported by patients with CNV (Choroidal Neovascularization)?

Patients with choroidal neovascularization (CNV) commonly report distorted vision as a visual symptom due to the abnormal blood vessel growth in the choroid underneath the retina. This aberrant growth can lead to fluid leakage, scarring, and light distortion, all of which can significantly impact the visual perception of straight lines, causing them to appear wavy or warped. This phenomenon is often referred to as metamorphopsia, which is specifically associated with retinal disorders like CNV.

While fluctuations in vision and other symptoms can occur in various eye conditions, they are not as specifically characteristic of CNV as distorted vision. Color blindness is typically unrelated to the mechanisms of CNV, which primarily affects the central visual pathways rather than color processing. Night blindness can also occur for different reasons and is not a primary symptom associated with the conditions leading to CNV. Therefore, distorted vision is the most representative symptom for patients dealing with CNV.
