What cause the sclera turn brown?
There are 3 main colours that your sclera can go- red/blue/yellow. A blue sclera is usually due to a condition known as osteogenesis imperfecta. This is a genetic bone disorder which results in a deficiency in the connective tissue throughout the body. The sclera contains connective tissue. The reason that the sclera appears blue is that the sclera is very thin in this condition so you can see the underlying choroid. A yellow sclera occurs with age. This is basically due to fatty deposits in the sclera causing a yellow appearance. Red sclera means blood. This can be a result of either episcleritis or scleritis. Episcleritis is a sudden, painless redness of the eye and is easily treated. Scleritis is a gradual onset of a painful, red eye and it is considered to be of medical urgency as if left untreated, it can lead to blindness.
