The Diagnostic Impact of Color Vision

Study suggests reduced survival in bladder cancer patients with color vision deficiency

1

Color vision deficiency (CVD) affects approximately one in 12 males and one in 200 females, impacting their ability to detect visible blood.
2

Patients with bladder cancer and CVD showed lower overall survival rates compared to those without CVD, indicating a potential diagnostic gap.
3

In contrast, no significant survival difference was observed in colorectal cancer patients with CVD, suggesting varying impacts by cancer type.
4

CVD may lead to delayed care-seeking due to misinterpretation of blood in urine or stool, particularly in bladder cancer.
5

The study highlights the need for routine assessment of CVD in clinical practice to improve cancer detection and patient outcomes.
