Ophthalmology. 2016. 96 6. As patients are started on hydroxychloroquine, they will have a baseline retinal screen usually at 3 months but certainly within 12 months of starting, organised by the specialist. And screening tests, but that screening begins after one year of therapy for all patients on chloroquine. Screening may be best incorporated into the hospital eye service via virtual clinics. The results of screening should be communicated back to the prescribing doctor, patient and GP as normal, possible or definite hydroxychloroquine retinopathy.

The goal for Plaquenil Screening to detect toxicity early and stop the medication as soon as possible if present. Functional test that focus on central field sensitivity may pick up early toxicity. Early structural changes may be difficult to detect and high resolution optical coherence tomography OCT and fundus autofluorescence are very. Discussion. A risk factor for Plaquenil hydroxychloroquine retinotoxicity is a daily dose that exceeds 5.0 mg of drug per kg of body weight. The tool on the right simply calculates this threshold based on a patient’s real body weight. It’s important to understand that the daily dose is only one risk factor for plaquenil retinotoxicity.
