Mar 04, 2014 · In the early stages of chloroquine retinal toxicity, there appear psychophysical signs of retinopathy, characterized by a paracentral scotoma on threshold visual field testing, without any observable fundus change; also, possibly, by the presence of color vision defects. Some physicians suggest that lean body weight is more accurate when calculating daily dosage. If available, multifocal electroretinography, spectral domain optical coherence tomog raphy, and fundus. Visual complaints are primarily associated with central vision loss, and visual field or color vision anomalies The multifocal electroretinogram (mfERG) can provide objective corroboration for visual fields, and fundus autofluorescence (FAF) can show damage topographically. This has come to be known as bull’s-eye maculopathy. Automated 10-2 fields with white test object (found to be more sens than red) 4. The earliest signs of toxicity include bilateral paracentral visual field changes (best detected with a red test object) and a subtle granular depigmentation of the paracentral RPE. The drug-induced maculopathy is associated with the following risk factors: Cumulative dose level of 1,000 grams of plaquenil. • Subtle, repeatable visual field defectsshould be taken seriously and Plaquenil is manufactured in only a 200 mg tablet. These OCT alterations included (1) attenuation of the parafoveal ellipsoid zone and (2) loss of a clear continuous interdigitation zone.
