According to certain studies, it has been found these mutations originate from 19 different chromosomes and 56 different genes. The proliferative type of retinopathy can lead to impaired vision or color blindness. Sickle cell patients can develop sickle cell retinopathy, where sickle cells block the small blood vessels in the eye depriving the eye of oxygen and causing damage. In X-linked inheritance , the mother carries the mutated gene on one of her X chromosomes and will pass … Men are more likely to be color blind because of the way color blindness is inherited.

The genes that can determine if you red-green color blindness are passed down on the X-chromosome. Conditions such as color blindness are passed from parents to their children on groups of genes called chromosomes. And color vision may get worse as you get older — often because of cataracts (cloudy areas in the lens of the eye).

Both are found in the retina which is the layer at the back of your eye which processes images. The tiny blood vessels in the retina become swollen, which blocks the oxygen supply to the retina. The colorblindness gene is sex-linked, located on the X-chromosome, so a male need only 1 gene to inherit the trait, but a female needs two of the same gene to inherit. Hydroxychloroquine can cause serious eye problems including damage to the optic nerve and retina and corneal deposits.
