Table 2e Management of patients with possible retinopathy

From: The Royal College of Ophthalmologists recommendations on screening for hydroxychloroquine and chloroquine users in the United Kingdom: executive summary

Recommendation Grade
Patients with possible hydroxychloroquine retinopathy should continue drug treatment. This will reduce the risk of inappropriate treatment cessation. GPP
Patients with one abnormal test result on retinal imaging (SD-OCT & widefield FAF) but normal visual fields (including 30-2 protocol if appropriate) should return for annual review as per the screening schedule. This will reduce the risk of inappropriate treatment cessation. GPP
Patients with persistent visual field abnormalities in the context of normal structural imaging (SD-OCT & widefield FAF) may be referred for multifocal electroretinography. Treatment should continue until the outcome of electrophysiology is known. GPP
