While the infection is commonly known to affect the genital area, it can also affect other areas including the eye, throat and rectum. Chlamydia in the eye is sometimes referred to as chlamydial conjunctivitis.

Causes of chlamydial conjunctivitis

Similar to an infection in the genital area, chlamydial conjunctivitis is usually caused when the eyes come into contact with the semen or vaginal fluids of someone with a chlamydia infection [2].

Often people with chlamydial conjunctivitis will also have an associated genital infection, of which they may not be aware. If left untreated, a chlamydia infection may pass from the vaginal canal to a baby during childbirth, sometimes causing lung or eye infections in newborns[2].
