[Toxic maculopathy caused by antimalarial drugs: detection using spectral domain OCT: case reports].
Antimalarial drugs, such as chloroquine, are useful in the management of rheumatic diseases, but may cause a potentially blinding condition known as toxic maculopathy. This report describes the findings on standard and on high-resolution spectral domain ocular coherence tomography performed in a CirrusTM HD-OCTdevice in two patients with chloroquine maculopathy. In one case, a very similar aspect of retinal pigment epithelium (RPE) plaque atrophy occured in both angiographic and HD-OCT images obtained by 'en-face' (coronal) segmentation. In another patient with clinical signs of maculopathy and no angiographic abnormalities, signs of RPE atrophy could also be observed in HD-OCT scans, raising the possibility that this technique may allow the early detection of the disease.
