ISLAMABAD: Men with higher blood pressure are more likely to have impaired colour vision, a new study has found. Damage to certain parts of the eye that occurs as a result of high blood pressure could ultimately lead to vision loss and it’s possible that impaired colour vision could be a sign of future problems related to high blood pressure, BBC health reported.
According to researchers, it will be great if acquired colour vision impairment can be a harbinger of future hypertension-related complications.
Knowing that high blood pressure has been tied to certain eye diseases researchers evaluated the relationship between colour vision and eye disease, heart-related risk factors and lifestyle habits. The researchers recruited men ages 20 to 60 years old who were on active duty.
They looked at the men’s medical records, measured their blood pressure and gave them two tests to assess how accurately they could see and discriminate different colours. Both tests involve lining up a certain number of caps in order of hue.
Of the 872 men included in the study, 130 failed one test and 31 failed the other. After the researchers took into consideration other factors such as men’s weight, cholesterol, blood sugar levels and other eye diseases, they found that as blood pressure values rose, the odds of having impaired colour vision increased as well.
