noted macular pigment irregularity with small drusen, inner-outer segment layer disruption and thinning of the outer nuclear layer. The presence of bull’s-eye maculopathy indicates the disease has been progressing for years, resulting in foveal thinning and likely vision loss. all noted RPE atrophy, with the latter two specifically noting bull’s-eye maculopathy patterns, resembling chloroquine toxicity. In patients at risk or those with unclear presentation, optical coherence tomography (loss of IS/OS junctions), fundus autofluorescence (focal hyper or hypoautofluorescence), and multifocal electroretinography (paracentral depressions) may be … The risk is increased for patients taking more than 5mg/kg/day, those also taking Tamoxifen, and those with renal impairment.
