Three consecutive 10–2 visual fields with a red target in a patient taking hydroxychloroquine at toxic doses who developed retinopathy.

Notes: An incomplete annular scotoma in the zone from 2° to 8° from fixation is seen in the first visual field. This scotoma was reproducible (green-circled scotoma points) and enlarged (blue- and purple- circled scotoma points) from 2009 to 2011.

Abbreviations: FL, fixation losses; FN, false negatives; FP, false positives; FASTPAC, a bracketing strategy proprietary to the Humphrey visual field analyzer.
