What bacterium is responsible for causing trachoma infections leading to irreversible corneal damage?
*Chlamydia trachomatis*
Trachoma is identified as a specific infectious cause of corneal opacity that has historically affected particular geographic areas, leading to severe vision impairment or blindness. The causative agent is the bacterium known as *Chlamydia trachomatis*. The mechanism involves recurrent infections that trigger inflammation within the eye structure. Over time, this persistent inflammation leads to the scarring of the inner surface of the eyelid. As this scarred lid rubs repeatedly against the front of the eye—the cornea—it results in irreversible mechanical damage to that transparent surface. Although public health initiatives have managed to reduce its global burden significantly, it remains an important public health consideration in specific endemic regions.
