Famous impressionist painters suffered vision impairment and loss, which may have inspired the impressionist movement. Monet had well-documented vision problems. Degas lost central vision in one eye, in his thirties; and in the other eye in his fifties. Cassatt was diabetic, suffered from diabetic retinopathy and cataracts, and underwent multiple operations on her eyes. She reported her vision becoming dimmer, but continued to paint with oils using more vibrant colors. DuMaurier had retinal problems and was blind in his left eye.
The same types of vision losses exist today; and modern treatment is often medications, procedures and surgery directed at improving vision, or slowing or stopping vision loss. The root causes of many eye diseases and the means to prevent development of common eye diseases remain poorly understood.
Infectious pathogens will emerge as the cause of many non-traumatic eye diseases and syndromes. Chlamydia pneumonia, chlamydia trachoma, chlamydia psittacosis, H-pylori and toxoplasmosis can attack the eye, and damage the eye and vision, in a manner similar to the damage caused by the same pathogens in other organs and body systems.
