Yellow Vision

Introduction Yellow vision refers to the yellowing of the object, accompanied by blindness (decreased visual acuity in the context of increased illumination), blurred vision, reduced color vision, and dark spots in the side. Common in eye diseases or drug poisoning.

Cause

Yellow vision is found in carbon monoxide (CO) poisoning, drugs for treating heart disease, digitalis poisoning, excessive deworming mountain stagnation, diuretic hydrochlorothiazide (dioxane urinary plug), and anti-tuberculosis drug ethambutol. Scientists believe that these drugs are directly caused by the cone of color vision. Common to the following diseases: atrial tachycardia with atrioventricular block, CO poisoning, pigmentation disorders, lens disease, aphakic, jaundice, drugs (DDT, sulfa drugs, digitalis, streptomycin, aspirin, barbi Poisoning, allergies, etc.

Blurred vision, photophobia, flash, blind spots, halo around the item, yellow color. If this situation is discovered, it is necessary to go to the top three hospitals to check the situation clearly, so as not to delay the best treatment opportunity.

When you feel it, you need to check the fundus actively. Check the chromatogram and check the blood vessels in your eyes.

Differential diagnosis

1, black eye: is a physiological phenomenon, caused by head ischemia, so most black eyes phenomenon occurs in the case of overweight. The most serious point is the most serious.

2, blue and yellow weak: the difference in color discrimination is called weak color, and its boundary with color blindness is generally not easy to distinguish strictly, but the degree of severity is different. Color weakness includes weak color and partial color weakness (red weak, green weak, blue-yellow weak, etc.). Blue and yellow are also known as the third color blind. The patient's blue-yellow color is unclear and is identifiable to red and green. Blue and yellow are a type of color blindness.

3, blue and yellow blind: blue and yellow blind, also known as the third color blind. The patient's blue-yellow color is unclear and is identifiable to red and green. People with blue-yellow color blindness are difficult to recognize blue and yellow. Blue-yellow blindness includes blue blind (tritanopia, third color blindness) and blue weak (tritanomaly, third color weak). Blue-yellow blindness is one of color blindness.

4, red vision: red vision: negative acceleration is opposite to positive acceleration, inertial force pushes blood from the foot to the head, causing the head to form high blood pressure. The pilot will feel wearing a pair of red glasses, and the surrounding world will become a red world. After the aircraft is changed, the pilot's brain will still feel stinging, his face will swell and he will not open.

5, green vision: green vision because the brain is often affected by some direct stimulation or lesions.
