Evaluation of several tests in screening for chloroquine maculopathy
1Department of Ophthalmology, Hadassah University Hospital, Jerusalem, Israel.
Abstract:
Patients receiving antimalarial therapy, specifically hydroxychloroquine, for different periods were evaluated using contrast sensitivity test (CST) and results were compared with those of electro-retinography (EOG), and pattern visual evoked potential (PVEP), and a matching age control group. The results indicated CST to be most sensitive of the evaluated techniques particularly in patients under 40 years old. In 44.4% of the cases CST revealed macular dysfunction of which the other two methods of examination were not capable. Our findings suggest the CST is a reliable and practical method which could be used as an additional screening test for chloroquine maculopathy.
