It occurs in Fabry’s disease and as a side effect of various systemic medications, namely Corneal deposits called vortex keratopathy or corneal verticillata result from binding to cellular lipids and deposition of the drug in the basal epithelial layer of the cornea. Discontinuation of the drug usually causes the deposits to disappear over time.

    Novel technologies such as optical coherence tomography (OCT), fundus autofluorescence (FAF) and multifocal electroretinogram (mf ERG) may provide the earliest structural and functional evidence of toxicity in these stages.

Toxic maculopathy is usually reversible only in its earliest phases. If these drugs have caused skin, eyelid, corneal hydroxychloroquine or hair changes, this may be an indicator of possible drug-induced retinopathy. If cornea verticillata is associated with a drug that is known to produce retinal toxicities—most notably hydroxychloroquine, chloroquine, chlorpromazine, and tamoxifen—patients should be routinely monitored with automated visual fields plus spectral-domain optical coherence tomography SD OCT.
