In this paper, further investigation by fluorescein angiography and electroretinography (ERG) was undertaken to substantiate the possible toxic maculopathy due to quinine usage. Again, positive Amsler chart tests were found in 3 of 14 (21%) of the drug addicts with blurred vision, a common complaint among these patients. The results of 5 fluorescein angiography examinations demonstrated no leakage of dye, especially in the macula. Twenty-four ERG examinations revealed no statistical differences between the test group patients and the control subjects. It was concluded that there is a definite need to carefully examine the eyes of any person who has used quinine for a long time since positive Amsler chart tests were found in 37% of the drug addicts.
