This is usually a benign, self-limiting, suppurative conjunctivitis due to Chlamydia trachomatis - serotypes D-K.
In adults, the condition usually presents in sexually active young people. The agent tends to infect the urethra of the male and the cervix of the female. Transmission to the eyes is usually from the genitourinary tract. Indirect transmission may occur from unchlorinated swimming pools.
In infants, the agent may be acquired during birth by direct contamination of the conjunctiva with cervical secretions. The condition is then known as chlamydial ophthalmia neonatorum.
