She had no visual symp- toms but had been identified as being at risk of retinal toxicity due to the length of time on treatment and the significant cumulative dose received. On review, visual acuity was the following: right eye 6/7.5, left eye 6/12. Further investigation demonstrated classical findings of HCQ toxicity (Fig. 1). HCQ-induced retinal toxicity is more common than previ- ously thought . The new British Society for Rheumatology/ British Health Professionals in Rheumatology guidelines recommend formal ophthalmic investigation at baseline and at annual intervals in patients receiving treatment beyond 5 years. This should take the form of retinal imaging techniques to include spectrum domain OCT as traditional methods including Amsler charts are not sufficient . This will have implications for service provision. Updated guid- ance from the Royal College of Ophthalmologists is currently in consultation phase.
