N: 1. Disease of the eyes, 1690s, from Modern Latin trachoma, from Greek trakhoma “roughness,” from trakhys “rough.”
2. Trachoma continues to be hyperendemic in many of the poorest and most remote poor rural areas of Africa, Asia, Central and South America, Australia and the Middle East.
3. Trachoma is one of the oldest infectious diseases known to mankind. It is caused by Chlamydia trachomatis –a microorganism which spreads through contact with eye discharge from the infected person (on towels, handkerchiefs, fingers, etc.) and through transmission by eye-seeking flies.
If untreated, this condition leads to the formation of irreversible corneal opacities and blindness.
It is responsible, at present, for more than 3% of the world’s blindness but the number keeps changing due to the effect of socioeconomic development and current control programmes for this disease.
4. Chronic inflammatory disease of the eye caused by Chlamydia trachomatis, a bacterium-like microorganism that grows only within tissue cells of the infected host. The conjunctiva becomes thickened and roughened, and deformation may result. Extension of inflammation to the cornea occurs in varying degree; resultant scarring can lead to corneal opacity and blindness. Transmission occurs by personal contact with infective ocular secretions or indirectly by common use of a towel.
