Trachoma is one of the causes of vision loss. The disease is caused by bacteria and can develop and spread into an epidemic. Recognizing the signs of the disease early and treating it early is the best way to avoid complications caused by the disease.

The cause of trachoma is the bacteria Chlamydia Trachomatis. If trachoma is not treated, or treated late, it can cause complications that damage the cornea, affecting eye function.
