You will be told if any other tests are necessary and when you should be screened again.

Visual field testing is tested by an individual pressing a button when they see a light on a specialized type of eye test. Screening interval has also been updated. All patients will need a baseline screening before or within 1 year of initiation of hydroxychloroquine. The baseline examination includes a fundus examination. SD-OCT and visual field testing are added to the initial examination if a concurrent maculopathy is present.
