The preferential loss of photoreceptor IS/OS junction makes SD-OCT an ideal tool to identify early changes associated with Plaquenil retinal toxicity. PLAQUENIL film-coated tablets cannot be divided, therefore they should not be used to treat patients who weigh less than 31 kg. For radical cure of P. vivax and P. malariae infections, concomitant therapy with an 8-aminoquinoline compound is necessary. It is imperative that patients and physicians are aware of and watch for this drug’s ocular side effects.
