In the spring of 1868 a conference was held at Fort Laramie, in present day Wyoming, which resulted in a treaty with the Sioux. This treaty was to bring peace between the whites and the Sioux who agreed to settle within the Black Hills reservation in the Dakota Territory. The Black Hills of Dakota are sacred to the Sioux Indians. In the 1868 treaty, signed at Fort Laramie and other military posts in Sioux country, the United States recognized the Black Hills as part of the Great Sioux Reservation, set aside for exclusive use by the Sioux people.
As it relates to the eye, rheumatoid arthritis may lead to conditions such as dry eye, scleritis, or uveitis. Dry eye is a common condition in which the eyes do not produce adequate tears, leading to redness and irritation.
That prompts the lacrimal glands to produce so many tears that they overwhelm the eye's natural drainage system. Tear production tends to lessen with age, so dry eyes are more common in older adults. Some medical conditions and medications can also lead to dryness, as can a dry and windy environment. But the most common cause of dry eye syndrome is a chronic condition called keratoconjunctivitis sicca (KCS). People with this condition make tears, but the tears do not contain enough water. In addition to excessive tearing, symptoms of dry eye syndrome may include blurred vision, itchy eyes, or burning eyes.
