Sir,

We thank Drs Soomro and Buchan for their interest in our article and for their very pertinent comments regarding the risk of chlamydial conjunctivitis going undiagnosed when clinicians use our diagnostic algorithm to help assess patients presenting with red eye(s). We will add a footnote to the diagnosis of ‘infective conjunctivitis’ to alert the user to consider chlamydia if the patient is in one of the at-risk groups; <40 years of age or has other suggestive symptoms (genital discharge) or signs such as pre-auricular lymphadenopathy or as per our original advice if symptoms persist despite treatment with topical chloramphenicol.
